Wildlife Society Bulletin 42:430-437. \| Abstract \| Download	2018-09-30	Southern flying squirrels (Glaucomys volans; SFS) nest in naturally formed cavities in snags and hardwoods found in mature, oak (Quercus spp.)–hickory (Carya spp.) forests. Intensive forest fragmentation of the Midwest United States limits the number of available nesting trees. We quantified annual nest-site selection patterns by southern flying squirrels across fragmented landscapes of west-central Illinois,USA. We used radiotelemetry to measure nest-tree use by 55 SFS (30 males, 25 females) captured during 2014–2016. Of 105 nest trees used by SFS, live trees and snags comprised 75% and 25%, respectively. Probability of diurnal nest-tree use increased 1.08/1.00-cm increase in diameter-breast-height and by 1.50/1-unit increase in the number of overstorymast trees between random and nest-tree habitat areas (i.e., 300-m2 circular plots). Similarly, probability of diurnal nest-tree use increased 1.29/1-unit increase in the number of snags between random and nest-tree habitat areas. Our results revealed no intersexual differences in patterns of nest-site selection, which may reflect the tendency for SFS to compensate for reduced availability of key structural attributes (i.e., snags, overstory trees) across fragmented forests by exhibiting similar intersexual patterns of nest-tree use. Use of natural cavities for denning is encouraging, but also underscores the importance of unharvested oak–hickory forests in contributing essential habitat to SFS populations in fragmented Midwestern landscapes

Yates, J. R., C. J. Watkins, and M. C. Quist. 2016. Precision of hard structures used to estimate age of common carp. Northwest Science 90:195-205. \| Abstract	2016-06-30	Common carp Cyprinus carpio is a widely distributed non-native cyprinid in North America that often alters water quality and fish assemblage structure outside of its native distribution. Understanding age distributions and dynamic rate functions is critical for effective management of systems influenced by common carp, but requires the use of calcified structures that are accurate, precise, and have high readability. Otoliths (i.e., asteriscus) have been validated, but their removal requires sacrificing fish. In addition, unpublished studies have noted poor readability and difficulty in estimating ages from sectioned and whole otoliths. Various non-lethal hard structures for ageing common carp have been evaluated, but a comprehensive evaluation of the precision and relative readability among widely-used hard structures is lacking for common carp. We examined age estimates obtained from asteriscus otoliths, scales, pectoral fin rays, and dorsal spines of 207 common carp from Crane Creek Reservoir and Lake Lowell in southwestern Idaho. All structures were sectioned except for scales. Between-reader precision (i.e., between two readers), readability and its relationship with precision of age estimates (i.e., confidence ratings), and differences in age estimates among hard structures were evaluated. Percent agreement (PA) was lower and the coefficient of variation (CV) was higher for otoliths (PA = 18.4%; CV = 17.6) and scales (PA = 29.7%; CV = 15.4) compared to fin rays (PA= 51.7%; CV = 4.9) and dorsal spines (PA = 65.2%; CV = 3.0). Otoliths and scales had significantly lower mean confidence ratings assigned by readers than dorsal spines and pectoral fin rays. Furthermore, both readers displayed higher confidence in assigning ages to dorsal spines than pectoral fin rays. In general, age estimates from scales and sectioned otoliths were lower than both fin rays and dorsal spines. Between-reader analysis showed high exact and within-1 year agreement, low CV, and higher confidence ratings for sectioned dorsal spines when compared to the other structures.

(2018) Efficiently approximating the pareto frontier: hydropower dam placement in the Amazon basin. Proceedings of the Thirty-Second AAAI Conference on Artificial Intelligence. \| Abstract	2018-03-31	Real–world problems are often not fully characterized by a single optimal solution, as they frequently involve multiple competing objectives; it is therefore important to identify the so-called Pareto frontier, which captures solution trade-offs. We propose a fully polynomial-time approximation scheme based on Dynamic Programming (DP) for computing a polynomially succinct curve that approximates the Pareto frontier to within an arbitrarily small > 0 on treestructured networks. Given a set of objectives, our approximation scheme runs in time polynomial in the size of the instance and 1=. We also propose a Mixed Integer Programming (MIP) scheme to approximate the Pareto frontier. The DP and MIP Pareto frontier approaches have complementary strengths and are surprisingly effective. We provide empirical results showing that our methods outperform other approaches in efficiency and accuracy. Our work is motivated by a problem in computational sustainability concerning the proliferation of hydropower dams throughout the Amazon basin. Our goal is to support decision-makers in evaluating impacted ecosystem services on the full scale of the Amazon basin. Our work is general and can be applied to approximate the Pareto frontier of a variety of multiobjective problems on tree-structured networks.

Good practices for species distribution modeling of deep-sea corals and sponges: data collection, analysis, validation, and communication. Submitted to Frontiers in Marine Science. \| Abstract	2020-05-31	Resource managers in the United States and worldwide are tasked with identifying and mitigating trade-offs between human activities in the deep sea (e.g., fishing, energy development, and mining) and their impacts on habitat-forming invertebrates, including deep-sea corals and sponges (DSCS). Related management decisions require information about where DSCS occur and in what densities. Species distribution modeling (SDM) provides a cost-effective means of identifying potential DSCS habitat over large areas to inform these management decisions and data collection. Here we provide recommendations of good practices for DSCS SDM, especially in the context of data collection and management applications. Managers typically need information regarding DSCS encounter probabilities, densities, and sizes, defined at sub-regional to basin-wide scales and validated using subsequent, targeted data collections. To realistically achieve these goals, we recommend integrating available data sources in SDMs including fine-scale visual sampling and broad-scale resource surveys (e.g., fisheries trawl surveys). When possible, we recommend models fitted to presence-absence and density data rather than models fitted only to presence data, which are difficult to validate and can confound estimated probability of occurrence or density with sampling effort. Ensembles of models can provide robust predictions, while multi-species models leverage information across taxa and facilitate community inference. We also recommend that analysts include environmental predictor variables representing multiple spatial scales, model residual spatial autocorrelation, and quantify prediction uncertainty. To facilitate the use of models by managers, predictions should be expressed in units that are widely understood and should be validated at an appropriate spatial scale using a sampling design that provides strong statistical inference. We present three case studies for the Pacific Ocean that illustrate good practices with respect to data collection, modeling, and validation; these case studies demonstrate it is possible to implement our recommendations in real-world settings.

Paddlefish: Ecological, Aquacultural, and Regulatory Challenges of Managing a Global Resource. American Fisheries Society Symposium 88, Bethesda, MD. \| Abstract	2019-07-31	Recent advances in fisheries techniques have provided insights into distribution, abundance, habitat use, and life history for several fish species, many of which are applicable to Paddlefish (Polyodon spathula). We highlight three new, promising techniques for assessing Paddlefish populations, including: hard-part chemistry for identifying sources of recruits (both wild and stocked fish) and reconstructing environmental history of individual fish, advances in sonar technology for habitat mapping and abundance estimation, and development of eDNA as a detection tool where traditional fisheries gears are insufficient. We also identify potential impediments to applications of these techniques and recommend steps needed to further assess and enhance their applicability to Paddlefish management and conservation.

Through this retrospective we highlight the remarkable historic fisheries resources and causative reasons for establishing public fisheries agencies and the American Fisheries Society (AFS). Through a review of primary historical documents and literature for North America, this paper identifies: factors contributing to the founding of AFS and public fish commissions; shows how selected resource issues evolved; and documents how and why selected fisheries and aquatic habitat policies changed in response to those issues. Overexploitation, landscape-scale habitat alterations, mining, and dams were the causative agents for emergence of fisheries agencies and the AFS, and these factors remain relevant today. Beginning in the 1960s, North Americans grew tired of degraded waters and fisheries and forced policy changes that have directly and indirectly affected the fisheries we manage today. The historical events and resulting corrective legislation are taken for granted by those unaware that AFS has actively participated in developing policies to address these environmental issues. Further, AFS continues to play a vital role in identifying key issues, providing conduits for information to cope with impairments, and advocating for policies to conserve intact habitats and improve degraded systems. The struggles documented in this paper offer crucial lessons as we continue to be challenged by legacy resource issues and face emerging environmental stressors such as climate change as well as regression in long-standing environmental protection policies.

Marine Biology 166:4. \| Abstract	2018-12-31	Restoration of oyster habitat across Louisiana may offer a valuable approach to mitigating anthropogenic nutrient inputs to coastal estuaries. The eastern oyster (Crassostrea virginica) and the reefs they create provide significant ecosystem services, including potential nutrient mitigation via bioassimilation, burial, and oyster-mediated denitrification. This study measured bioassimilation, burial, and oyster-mediated sediment denitrification in near-shore shallow-water (< 1 m water depth) and deep-water (> 1 m water depth) oyster reefs in Louisiana. Carbon (C) and nitrogen (N) in shell and tissue was within the range of previous studies, but was found to be influenced by reproductive status, size, and habitat type. Changes in tissue percent N and C post spawning combined with significant reductions in tissue weight from the release of gametes, resulted in 20 and 46% reduction in tissue N and tissue C load (mg) for a 100 mm oyster, respectively. Percent N and C buried in sediments were highest at shallow-water reefs (0.52  0.05% and 8.92  0.89% respectively), likely due to their close proximity to the marsh edge and thus exposure to a greater influx of detrital material. Closed-system ex-situ incubations indicated net denitrification in all habitat types studied, with the highest rates exceeding 600 µmol m-2 hr-1 during the summer, but no enhancement attributable to oyster reefs specifically. Considering the large extent of reefs and oyster production across coastal Louisiana, oyster habitats may still contribute to nutrient mitigation, but their unique contribution likely comes from bioassimilation, and removal of tissue and or shell from the system. Efforts to predict oyster reef nutrient mitigation requires incorporating timing of harvest and habitat context.

Management decisions to address these effects (i.e., adaptation) require an understanding of the relative vulnerability of various resources to these stressors. To meet this need, the four Landscape Conservation Cooperatives along the Gulf partnered with the Gulf of Mexico Alliance to conduct this Gulf Coast Vulnerability Assessment (GCVA). Vulnerability in this context incorporates exposure and sensitivity to threats (potential impact), coupled with the adaptive capacity to mitigate those threats. Potential impact and adaptive capacity reflect natural history features of target species and ecosystems. The GCVA used an expert opinion approach to qualitatively assess the vulnerability of four ecosystems: mangrove, oyster reef, tidal emergent marsh, and barrier islands, and a suite of wildlife species that depend on them. More than 50 individuals participated in the completion of the GCVA, facilitated via Ecosystem and Species Expert Teams. Of the species assessed, Kemp’s ridley sea turtle was identified as the most vulnerable species across the Gulf Coast. Experts identified the main threats as loss of nesting habitat to sea level rise, erosion, and urbanization. Kemp’s ridley also had an overall low adaptive capacity score due to their low genetic diversity, and higher nest site fidelity as compared to other assessed species. Tidal emergent marsh was the most vulnerable ecosystem, due in part to sea level rise and erosion. In general, avian species were more vulnerable than fish because of nesting habitat loss to sea level rise, erosion, and potential increases in storm surge. Assessors commonly indicated a lack of information regarding impacts due to projected changes in the disturbance regime, biotic interactions, and synergistic effects in both the species and habitat assessments. Many of the assessors who focused on species also identified data gaps regarding genetic information, phenotypic plasticity, life history, and species responses to past climate change and sea level rise. Regardless of information gaps, the results from the GCVA can be used to inform Gulf-wide adaptation plans. Given the scale of climatic impacts, coordinated efforts to address Gulf-wide threats to species and ecosystems will enhance the effectiveness of management actions and also have the potential to maximize the efficacy of limited funding.

DOI:10.1038/s41598-018-32937-7. \| Abstract \| Download \| Publisher Website	2018-09-30	Spatial heterogeneity, or composition and configuration of a landscape, plays a role in many biological and ecological processes. In spatial ecology, understanding movements of a species in relation to the landscape can assist wildlife managers in better understanding other processes, including habitat use and disease transmission. In the northeastern United States (Northeast), chronic wasting disease has been detected in populations of white-tailed deer (Odocoileus virginianus), and understanding the relationship between landscape and size of home range may provide a basis for disease surveillance and containment efforts. The objectives of our study were to (1) compare size of home range between sexes and among study areas for white-tailed deer occupying a continuum of forested landscapes from highly fragmented to contiguous and (2) investigate relationships between size of home range and measures of landscape composition and configuration. We observed differences in size of 95% home range between males (3.77 km2) and females (1.83 km2) across all study areas, as well as between deer in highly fragmented and contiguous landscapes. We developed 20 linear regression models that contained measures of landscape that were correlated with size of home range, and the best model showed that size of home range increased with connectivity of forest cover. Understanding this relationship may provide a foundation for disease surveillance efforts, because size of home range may represent the scale at which disease will spread. Therefore surveillance should be conducted in a manner that reflects connectivity of landscape at a local scale.

We developed and tested 2 estimators based on a combination of GPS radiocollar location-fix failure and distance traveled between locations. We developed a quantitative method employing Generalized Additive Models to smooth time series of wolf data to estimate denning onset. In contrast, 3 study authors with first-hand experience with the study wolves implemented a subjective method of estimating denning onset by visual inspection of detection and distance traveled data. We then tested the visual method for repeatability by subjecting it to 10 wolf experts not associated with this study. Side-by-side comparison of estimators indicates that denning onset can be precisely measured using GPS detection success and distance traveled. Furthermore, the visual-inspection method was simple and rapid to implement and yielded more accurate (relative to assumed onset dates of denning-onset dates) and precise results compared to the quantitative estimator. Although the Generalized Additive Model based approach had the advantage of estimating denning onset objectively following a set of prescribed rules in a statistical inferential framework, we found the method required significant technical capacity to implement and did not represent an improvement over simple visual-inspection–based estimates of denning onset.

Northwest Science 89:280-296. \| Abstract	2015-12-31	Knowledge of the population structure and dynamics of nonnative species is critical for determining potential problems and solutions for management. Numerous species have been introduced to Coeur d’Alene Lake, Idaho over the last century, but minimal research has been completed to understand their population dynamics. The objective of this study was to describe the population demographics and dynamics of northern pike Esox lucius and smallmouth bass Micropterus dolomieu, two important nonnative sport fishes in the system. Age and size structure of northern pike and smallmouth bass were similar across bays. The oldest northern pike was age 7 and the oldest smallmouth bass was age 11. The recruitment coefficient of determination was 0.99 for northern pike and 0.98 for smallmouth bass, indicating very stable recruitment. Total annual mortality was estimated as 66% for northern pike and 42% for smallmouth bass. Growth of northern pike in Coeur d’Alene Lake was comparable to the 50-75th percentiles of growth exhibited by lentic northern pike populations across North America. Growth of northern pike in Coeur d’Alene Lake was most similar to populations in the north-central and northeast United States with fast growth rates and short life spans. In contrast, smallmouth bass growth was extremely slow and generally fell within the 5th percentile of lentic smallmouth bass populations in North America. Smallmouth bass growth in Coeur d’Alene Lake was similar to other populations in northern regions of the United States displaying slow growth rates with high longevity. Results of this study provide important insight on nonnative northern pike and smallmouth bass population dynamics.

Comparing the effects of swimming exercise and dissolved oxygen on the performance, health, and welfare of early-rearing Atlantic salmon Salmo salar. Aquaculture Research. \| Abstract	2017-09-30	Swimming exercise, typically measured in body-lengths per second (BL/s), and dissolved oxygen (DO), are important environmental variables in fish culture. While there is an obvious physiological association between these two parameters, their interaction has not been adequately studied in Atlantic salmon Salmo salar. Because exercise and DO are variables that can be easily manipulated in modern aquaculture systems, we sought to assess the impact of these parameters, alone and in combination, on the performance, health, and welfare of juvenile Atlantic salmon. In our study, Atlantic salmon fry were stocked into twelve circular 0.5 m3 tanks in a flow-through system and exposed to either high (1.5-2 BL/s) or low (<0.5 BL/s) swimming speeding and high (100% saturation) or low (70% saturation) DO while being raised from 10g to approximately 350g in weight. Throughout the study period, we assessed the impacts of exercise and DO concentration on growth, feed conversion, survival, and fin condition. By study’s end, both increased swimming speed and higher DO were independently associated with a statistically significant increase in growth performance (p<0.05); however, no significant differences were noted in survival and feed conversion. Caudal fin damage was associated with low DO, while right pectoral fin damage was associated with higher swimming speed. Finally, precocious male sexual maturation was associated with low swimming speed. These results suggest that providing exercise and dissolved oxygen at saturation during Atlantic salmon early rearing can result in improved growth performance and a lower incidence of precocious parr.

Transactions of the American Fisheries Society 145:786-794. \| Abstract \| Download	2016-06-30	Fishery-independent surveys are an important source of information for making inferences about the temporal dynamics of ecologically and recreationally important fisheries. For example, time-series of catch per effort data are often examined for the presence of long-term trends. However, it is also of interest to know if certain sampled locations are exhibiting temporal patterns that deviate from the overall pattern exhibited across all sampled locations. These ‘unusual’ sites may be the result of site-specific abiotic (e.g., habitat) or biotic (e.g., the presence of an invasive species) factors that cause them to respond differently to natural or anthropogenic drivers of population dynamics or to management actions. We present a Bayesian model selection approach that allows for detection of ‘unique’ sites—locations that display temporal patterns with documentable inconsistencies from the overall global average temporal pattern. We apply this modeling approach to long-term gillnet data for yellow perch in Oneida Lake, but the approach is also relevant to shorter time-series data. We used this approach to identify six unique temporal patterns among 15 sampled locations, and describe the magnitude of difference between these patterns and the lake-wide average. Detection of unique sites may be informative to management decisions related to prioritization of rehabilitation or restoration efforts, stocking decisions, determination of fishable areas, and to further understanding changes to ecosystem dynamics.

Avian community response to vegetation and water level management in restored wetlands at the Humacao Nature Reserve, Puerto Rico. Caribbean Naturalist 72:1-24. \| Abstract \| Download	2020-02-28	Coastal wetlands of the Caribbean have been greatly reduced in area and quality, and information on wildlife responses to management is lacking. We applied wetland management practices (disking, water level management) in a site historically disturbed by <i>Saccharum spp.</i> L. (sugarcane) cultivation at the Humacao Nature Reserve, southeastern Puerto Rico, and evaluated avian community response. We conducted weekly bird surveys and nest searches on disked and non-disked plots within recently constructed impoundments. The avian community shifted from 16 upland dominated species pre-restoration, to 67 wetland-dependent species at the end of our study (2001-2002). Ordination analysis indicated avian guild use of plots varied with environmental variables. Bird species diversity was not influenced by treatment, month, or salinity levels but was influenced by water depth and vegetation cover. Bird abundance was influenced by water depth, but not by treatment, month, salinity or vegetation cover. Furthermore, water depths of 0.10 – 0.20 m and salinity ≤ 15 ppt promoted habitat conditions suitable for a diverse wetland avian community. We located 268 nests of 8 wetland bird species and observed adults with young of various other waterbirds, including species of conservation concern such as <i>Dendrocygna arborea</i> (West Indian Whistling Duck) and <i>Porzana flaviventer</i> (Yellow-breasted Crake). Bird community responses suggest that management practices (i.e., water level management and soil disturbance) can improve wetland biodiversity in abandoned sugarcane fields of Puerto Rico. Moreover, these practices may benefit wetland biodiversity in other Caribbean islands with a similar history of land use and habitat degradation.

Transactions of the American Fisheries Society 146:584-593. [Featured Article] \| Abstract	2017-04-30	Unexpected shifts in the state-space conditions of an ecosystem can result in unintended and undesirable conditions, jeopardizing conservation efforts and efficacy of natural resource management. Previous research has identified general statistical behaviors associated with major ecological shifts, yet reliable prediction of these events remains limited. Development of statistical indicators to detect and forecast large-scale change (i.e., regime shifts) in ecological systems could prove valuable for better understanding population dynamics, continuing effective monitoring of fisheries resources, and allowing for timely management actions. Changes in mean and variance have been previously associated with large-scale shifts in ecosystems; here we provide evidence that source components contributing to total variability may also be responsive to large-scale shifts and therefore have potential as new statistical indicators of ecological response to a changing environment. We present a case study from Oneida Lake in NY that evaluates walleye catch rates over time in response to changes to tropho-dynamics and an exotic species invasion. Our results indicate that variance structure provides insight into how an ecosystem changes across space and through time, and also may serve as an indicator of instability and transition into an alternate stable state.

Limnology and Oceanography: Methods 13: 568-586. \| Abstract	2015-11-30	Golden alga (Prymnesium parvum) is a toxic haptophyte that has caused considerable ecological damage to marine and inland aquatic ecosystems worldwide. Studies focused primarily on laboratory cultures have indicated that toxicity is poorly correlated with the abundance of golden alga cells. This relationship, however, has not been rigorously evaluated in the field where the mix of toxic compounds produced by golden alga may differ from cultures, and environmental conditions are also different. The ability to predict toxicity using readily-measured environmental variables and golden alga abundance would allow managers rapid assessments of ichthyotoxicity potential without laboratory bioassay confirmation, which requires additional resources to accomplish. To assess the potential utility of these relationships, several a priori models relating lethal levels of golden alga ichthyotoxicity to golden alga abundance and environmental covariates were constructed. Model parameters were estimated using archived data from four river basins in Texas and New Mexico (Colorado, Brazos, Red, Pecos), their predictive ability was quantified using cross-validation, sensitivity, and specificity, and the relative importance of environmental covariates was determined by Akaike Information Criterion (AIC) values and Akaike weights. Overall, abundance was a generally good predictor of ichthyotoxicity as cross validation of golden alga abundance-only models ranged from ~80% to ~90% (leave-one-out cross-validation). Environmental covariates improved predictions, especially the ability to predict lethally toxic events (i.e. increased sensitivity), and top-ranked environmental variables differed among the four basins. These associations may be useful for monitoring as well as understanding the abiotic factors that influence toxicity during blooms.

Journal of Experimental Biology 223: doi: 10.1242/jeb.226563. \| Abstract	2020-09-30	Variation in life history expression is thought to arise from selection acting through physiological mechanisms, but selection pressures may differ or even conflict between life stages. High offspring predation risk can favor fast growth rates among species that may be achieved by faster post-natal metabolic rates. Faster metabolism, on the other hand, may create costs for adults, such that species with low adult mortality rates may be expected to minimize such adult costs through slower metabolism. Thus, mortality at the two different life stages may differentially influence offspring metabolism. We tested these possibilities among 43 songbird species studied on three continents. We found that nest predation risk and adult mortality probability were indeed interactive in their association with offspring metabolic rates across species. Our results provide a rare example of ecological sources of mortality during different life stages being correlated with post-natal metabolic rate as a mechanism underlying offspring growth.

Journal of Fish Biology 89:1720-1739. doi:10.1111/jfb.13078 \| Abstract	2016-09-30	Increased freshwater growth of juvenile steelhead Oncorhynchus mykiss improved survival to smolt and adult stages, thus prompting an examination of factors affecting growth during critical periods that influenced survival through subsequent life stages. For three tributaries with contrasting thermal regimes, a bioenergetics model was used to evaluate how feeding rate and energy density of prey influenced seasonal growth and stage-specific survival of juvenile O. mykiss. Sensitivity analysis examined target levels for feeding rate and energy density of prey during the growing season that improved survival to the smolt and adult stages in each tributary. Simulated daily growth was greatest during warmer months (1 July to 30 September), whereas substantial body mass was lost during cooler months (1 December to 31 March). Incremental increases in annual feeding rate or energy density of prey during summer broadened the temperature range at which faster growth occurred and increased the growth of the average juvenile to match those that survived to smolt and adult stages. Survival to later life stages could be improved by increasing feeding rate or energy density of the diet during summer months, when warmer water temperatures accommodated increased growth potential. Higher growth during the summer period in each tributary could improve resiliency during subsequent colder periods that lead to metabolic stress and weight loss. As growth and corresponding survival rates in fresh water are altered by shifting abiotic regimes, it will be increasingly important for fisheries managers to better understand the mechanisms affecting growth limitations in rearing habitats and what measures might maintain or improve growth conditions and survival.

Landscape and flow metrics affecting the distribution of a federally-threatened fish: Improving management, model fit, and model transferability. Ecological Modelling 342 (2016) 1–18 \| Abstract	2016-10-31	Truncated distributions of pelagophilic fish have been observed across the Great Plains of North America, with water use and landscape fragmentation implicated as contributing factors. Developing conservation strategies for these species is hindered by the existence of multiple competing flow regime hypotheses related to species persistence. Our primary study objective was to compare the predicted distributions of one pelagophil, the Arkansas River Shiner Notropis girardi, constructed using different flow regime metrics. Further, we investigated different approaches for improving temporal transferability of the species distribution model (SDM). We compared mean annual flow with three additional flow metrics, the 75th percentile of daily flow, the number of zero-flow days, and the number of days above 55th percentile flows, to examine the relative importance of flows during the spawning period. Building on an earlier SDM, we added the covariates well water use, point-source discharges, and non-native species presence to a structured variable framework. We assessed the effects on model transferability and fit of reducing multicollinearity using Spearman’s rank correlations, variance inflation factors, and principal component analysis, as well as altering the regularization coefficient (β) within MaxEnt. The 75th percentile of daily flow was the most important flow metric related to structuring the species’ distribution. The number of wells and point source discharges were also highly ranked. At the default level of β, model transferability was improved using all methods to reduce collinearity; however, at higher levels of β, the correlation method performed best. Using β = 5 provided the best model transferability, while retaining the majority of variables that contributed 95% to the model. This study provides a workflow for improving model transferability and also presents water-management options that may be considered to improve the conservation status of pelagophils.

North American Journal of Fisheries Management 38:549-564. DOI: 10.1002/nafm.10048 \| Abstract	2018-06-30	Endemic to the Apalachicola River Basin of the southeastern U.S., the Shoal Bass Micropterus cataractae is a fluvial-specialist sportfish that is imperiled because of anthropogenic habitat alteration. To counter population declines, restorative stocking efforts are becoming an increasingly relevant management strategy. However, population-genetic structure within the species is currently unknown, but could influence management decisions like brood source location. Leveraging a range-wide collaborative effort to collect and genotype specimens with 16 microsatellite loci, our objective was to characterize range-wide hierarchical population structure and genetic differentiation of Shoal Bass, including an examination of structuring mechanisms such as relatedness and inbreeding levels. Shoal Bass were collected from 13 distinct locations throughout its range (N ≥ 17 per location). Our results revealed appreciable population structure, with five distinct Shoal Bass populations identifiable at the uppermost hierarchical level that generally corresponded with natural geographic features and anthropogenic barriers. Additional substructure was recovered within several of these populations, wherein differences appeared related to spatial isolation and local population dynamics. An analysis of molecular variance revealed that 3.6% of the variation in our dataset was accounted for among three larger river drainages, whereas 87.4% was within the 13 sample sites. Results provide a population-genetic framework that can inform future management decisions, such as brood source location, so that genetic diversity within- and among- populations is conserved and overall adaptability of the species is maintained.

Journal of the Southeastern Association of Fish and Wildlife Agencies 5:1-9. \| Abstract \| Publisher Website	2018-04-30	The shoal bass (Micropterus cataractae) is a sportfish endemic to the Apalachicola-Chattahoochee-Flint Basin of the southeastern United States. Introgression with several non-native congeners poses a pertinent threat to shoal bass conservation, particularly in the altered habitats of the Chattahoochee River. Our primary objective was to characterize hybridization in shoal bass populations near Atlanta, Georgia, including a population inhabiting Big Creek and another in the main stem Chattahoochee River below Morgan Falls Dam (MFD). A secondary objective was to examine the accuracy of phenotypic identifications below MFD based on a simplified suite of characters examined in the field. Fish were genotyped with 16 microsatellite DNA markers, and results demonstrated that at least four black bass species were involved in introgressive hybridization. Of 62 fish genotyped from Big Creek, 27% were pure shoal bass and 65% represented either F1 hybrids of shoal bass x smallmouth bass (M. dolomieu) or unidirectional backcrosses towards shoal bass. Of 29 fish genotyped below MFD and downstream at Cochran Shoals, 45% were pure shoal bass. Six hybrid shoal bass included both F1 hybrids and backcrosses with non-natives including Alabama bass (M. henshalli), spotted bass (M. punctulatus), and smallmouth bass. Shoal bass alleles comprised only 21% of the overall genomic composition in Big Creek and 31% below MFD (when combined with Cochran Shoals). Phenotypic identification below MFD resulted in an overall correct classification rate of 86% when discerning pure shoal bass from all other non-natives and hybrids. Results suggest that although these two shoal bass populations feature some of the highest introgression rates documented, only a fleeting opportunity may exist to conserve pure shoal bass in both populations. Continued supplemental stocking of pure shoal bass below MFD appears warranted to thwart increased admixture among multiple black bass taxa, and a similar stocking program could benefit the Big Creek population. Further, selective removal of non-natives and hybrids, which appears to be practical with phenotypic identification, may provide increased benefits towards conserving genetic integrity of these shoal bass populations.

Journal of The American Society of Mining and Reclamation 5:45-46 \| Abstract \| Publisher Website	2016-06-30	Within the central Appalachia Coalfields, the aquatic impacts of large-scale land uses are of particular ecological concern. Coal mining practices, particularly surface coal extraction and associated valley fills, both directly and indirectly effect physical stream habitat and water quality. Additionally, many residential areas in this region are concentrated in the stream valley whereby they impact stream and riparian habitat. For example, runoff and untreated sewage into area streams continue to degrade water quality. Identification and quantification of land use impacts to ecosystems are a necessary first step to aid in mitigation of negative consequences to biota. However, oftentimes quantifying physical environmental quality such as stream and riparian habitat can be quite difficult, particularly when there are time or fiscal limitations. Standard protocols such as the U.S. EPA’s Stream Habitat Rapid Bioassessment Protocol have been established to be cost and time effective (Barbour et al 1999). This protocol estimates ten different stream and riparian conditions on a scale of 0 to 20. However, using estimations can be problematic due to large potential variation in the scoring depending on differences in training, experience, and opinion of the personnel doing the estimations. In order to help negate this and provide a simplified process, the U.S. Army Corps of Engineers (USACE) developed a functional assessment for streams that measures 11 stream and riparian parameters along with watershed land use to calculate three different scores, a hydrology score, biogeochemical score, and habitat score. In our study, we examined the correlation of stream salamanders to the three USACE scores. In the summer of 2013, we visited 70 sites (sampled three times each) in the southwest Virginia Coalfields to collect salamanders and quantify stream and riparian microhabitat parameters. Using an occupancy analysis we found strong relationships among three Desmognathus spp. and the USACE Habitat FCI score.

DOI: 10.1002/tafs.10054 \| Abstract	2018-03-31	Recruitment of many fish populations is inherently highly variable interannually. However, this variability can be synchronous at broad geographic scales due to fish dispersal and climatic conditions. Herein, we investigated recruitment synchrony of Silver Carp Hypophthalmichthys molitrix across the Mississippi River basin. Year-class strength (YCS) and synchrony of nine populations (maximum linear distance = 806.4 km) were indexed using catch-curve residuals correlated between sites and related to local and regional climatic conditions. Overall, Silver Carp YCS was not synchronous among populations, suggesting that local environmental factors are more important determinants of YCS than large-scale environmental factors. Variation in Silver Carp YCS was influenced by river base flow and discharge variability at each site, indicating that extended periods of static local discharge benefit YCS. Furthermore, river discharge and air temperature were correlated and synchronized among sites, but only similarities in river discharge were correlated with Silver Carp population synchrony, indicating that similarities in discharge (i.e., major flood) among sites can positively synchronize Silver Carp YCS. The positive correlation between Silver Carp YCS and river discharge synchrony suggests that regional flood regimes are an important force determining the degree of population synchrony among Mississippi River Silver Carp populations.

Herpetological Conservation and Biology 13(2):331-340. \| Abstract \| Download	2018-08-31	Accurate population estimates and assessments of trajectory are an essential part of harvest management for game species and conservation action plans for protected species. Long-term monitoring can lead to ecological understanding by identifying biotic and abiotic drivers of population dynamics. Spotlight surveys are a widely used method to monitor abundance and size-class structure of crocodilian populations. The American Alligator (Alligator mississippiensis) has recovered from significant population reductions in the southeastern United States. The Mississippi Department of Wildlife, Fisheries, and Parks (MDWFP) has conducted alligator spotlight surveys since 1971 to monitor populations. We analyzed this long-term alligator survey dataset to assess possible trends in counts as a proxy for potential population changes. We tested for a positive trend in count data over 46 y and evaluated covariates that could influence counts to assist future survey protocols. Alligator counts during 1971–2016 increased across survey routes in Mississippi. This observed positive response may represent an increase of the alligator population in Mississippi as a result of conservation benefits accrued from improved wetland conditions and species-specific management policies. Evaluation of survey covariates indicated recent rainfall and increasing wind velocity had negative effects on alligator counts while increasing water temperature had a positive effect. Implementing robust survey techniques will improve the reliability of alligator monitoring data and their application to the management of alligator populations. Further, these improved approaches may be useful to other conservation and management agencies as well as for other crocodilian species.

Canadian Journal of Fisheries and Aquatic Sciences 77:1564-1573. \| Abstract	2020-06-30	The ability of PIT tag data to improve demographic parameter estimates has led to the rapid advancement of PIT tag systems. However, ghost tags create uncertainty about detected tag status (i.e. live fish or ghost tag) when using mobile interrogation systems. We developed a method to differentiate between live fish and ghost tags using a random forest classification model with a novel data input structure based on known fate PIT tag detections in the San Juan River, NM, CO, and UT, USA. We used our model to classify detected tags with an overall error rate of 6.8% (1.6% ghost tags error rate and 21.8% live fish error rate). The important variables for classification were related to distance moved and response to flood flows; however, habitat variables did not appear to influence model accuracy. Our results and approach allow the use of mobile detection data with confidence and allow for greater accuracy in movement, distribution, and habitat use studies, potentially helping identify influential management actions improving our ability to conserve and recover endangered fish.

We measured and compared the hydraulic residence time, particle removalefficiency, and measures of velocity using several tools. Computational fluid dynamics was used first tocharacterize hydraulics in the proposed retrofit that included removal of the traditional Burrows ponddividing wall and establishment of four counter rotating cells with appropriate drains and inlet water jets.Hydraulic residence time was subsequently established in the four full scale test tanks using measures ofconductivity of a salt tracer introduced into the systems both with and without fish present. Vertical andhorizontal velocities were also measured with acoustic Doppler velocimetry in transects across each ofthe rearing systems. Finally, we introduced ABS sinking beads that simulated fish solids then followed thekinetics of their removal via the drains to establish relative purge rates. The mixed cell raceway providedhigher mean velocities and a more uniform velocity distribution than did the Burrows pond. Vectorsrevealed well-defined, counter-rotating cells in the mixed cell raceway, and were likely contributingfactors in achieving a relatively high particle removal efficiency-88.6% versus 8.0% during the test period.We speculate retrofits of rearing ponds to mixed cell systems will improve both the rearing environmentsfor the fish and solids removal, improving the efficiency and bio-security of fish culture. We recommendfurther testing in hatchery production trials to evaluate fish physiology and growth.

DOI: 10.1080/02755947.2016.1204391 \| Abstract \| Publisher Website	2016-09-30	Management of Blue Catfish Ictalurus furcatus and Channel Catfish I. punctatus for trophy production has recently become more common. Typically, trophy management is attempted with length-based regulations that allow for the moderate harvest of small fish but restrict the harvest of larger fish. However, the specific regulations used vary considerably across populations, and no modeling efforts have evaluated their effectiveness. We used simulation modeling to compare total yield, trophy biomass (Btrophy), and sustainability (spawning potential ratio [SPR] > 0.30) of Blue Catfish and Channel Catfish populations under three scenarios: (1) current regulation (typically a length-based trophy regulation), (2) the best-performing minimum length regulation (MLRbest), and (3) the best-performing length-based trophy catfish regulation (LTRbest; “best performing” was defined as the regulation that maximized yield, Btrophy, and sustainability). The Btrophy produced did not differ among the three scenarios. For each fishery, the MLRbest and LTRbest produced greater yield (>22% more) than the current regulation and maintained sustainability at higher finite exploitation rates (>0.30) than the current regulation. The MLRbest and LTRbest produced similar yields and SPRs for Channel Catfish and similar yields for Blue Catfish; however, the MLRbest for Blue Catfish produced more resilient fisheries (higher SPR) than the LTRbest. Overall, the variation in yield, Btrophy, and SPR among populations was greater than the variation among regulations applied to any given population, suggesting that population-specific regulations may be preferable to regulations applied to geographic regions. We conclude that LTRs are useful for improving catfish yield and maintaining sustainability without overly restricting harvest but are not effective at increasing the Btrophy of catfish.

DOI: 10.1080/00028487.2016.1143395 \| Abstract	2016-04-30	Species distribution models are useful tools to evaluate species-habitat relationships, though more often developed to evaluate factors controlling fish assemblages in lotic environment and less often in lentic systems. We evaluated species-habitat interactions for commonly captured fishes in six Oklahoma reservoirs using tandem hoop nets. We used hierarchical Bayesian multi-species N-mixture models to evaluate detection- and abundance-habitat relationships. Twelve species were captured, equating to 7,212 fish with channel catfish (46%), bluegill (25%), and white crappie (14%) comprising the majority of the catch. Detection estimates ranged from 8% to 69%, and modeling results suggested that fishes were primarily influenced by reservoir size and context, water clarity and temperature, and land-use types. Species were differentially abundant within and among habitat types, consisting of some fishes being found more abundant in turbid, less impacted (urbanization and agriculture) reservoirs with greater shoreline lengths; whereas, other species were found more often in clear, nutrient rich impoundments with generally less shoreline length and increased percentage agriculture. Our results demonstrate that habitat and reservoir characteristics may differentially benefit species and assemblage structure. This study provides a useful framework for evaluating capture efficiency for not only hoop nets but other gears used to sample fishes in reservoirs.

We did not find a difference in detection probabilities, although only a large difference would have been detectable with our sample size. Extraneous heat signatures from reflected solar radiation and dense vegetation were key factors limiting the usefulness of thermal imagers for locating nests.

Predation by Northern Pikeminnow and tiger muskellunge on juvenile salmonids in a high–head reservoir: implications for anadromous fish reintroductions. Transactions of the American Fisheries Society 145:521-536. \| Abstract	2016-04-30	The suitability of reservoir habitat for rearing anadromous salmonids and interactions with resident fish affect the feasibility of reintroductions above high–head dams. We evaluated the predation risk to anadromous salmonids considered for reintroduction in Merwin Reservoir on the North Fork Lewis River in Washington State for two use scenarios: year–round rearing and smolt migration. We characterized the role of the primary predators, Northern Pikeminnow Ptychocheilus oregonensis and tiger muskellunge Esox, lucius x E. masquinongy using stable isotopes and stomach content analysis, quantified seasonal per–capita predation using bioenergetics modeling, evaluated the size and age structures of the populations, and combined these inputs to estimate predation rates of size–structured population units. Northern Pikeminnow of fork length (FL) ≥ 300 mm were highly cannibalistic with modest seasonal per–capita ¬predation on salmonids, but were disproportionately much less abundant than smaller, less piscivorous conspecifics. The annual predation on Kokanee Oncorhynchus nerka (in biomass) by a size–structured u¬nit of 1,000 Northern Pikeminnow of FL ≥ 300 mm was analogous to 16,000–40,000 age–0 spring Chinook Salmon rearing year–round, or 400–1,000 age–1 smolts migrating April–June. The per–capita consumption of salmonids by Northern Pikeminnow of FL ≥ 200 mm was relatively low, due in large part to spatial segregation during the summer and the skewed size distribution of the predator population. Tiger muskellunge fed heavily on Northern Pikeminnow, other non–salmonids, and minimally on salmonids. Predation by tiger muskellunge, in addition to cannibalism, likely contributed to low recruitment of larger (more piscivorous) Northern Pikeminnow, with the effect being decreased predation risk to salmonids. This study highlights the importance of evaluating trophic interactions within reservoirs slated for reintroduction, as they can be functional migration corridors and may offer profitable juvenile–rearing habitats despite hosting abundant predator populations.

Journal of the Southeast Association of Fish and Wildlife Agencies 4:60-65. \| Abstract	2017-06-30	Accurate age and growth information is essential in successful management of fish populations and for a complete understanding of early life history. We validated daily ring formation, including the timing of first ring formation, for Spotted Gar (Lepisosteus oculatus), a species of conservation concern, through 127 days post-hatch. From fry produced from hatchery-spawned specimens, up to 10 individuals per week were sacrificed and their otoliths (sagitta, lapilli, and asteriscus) removed for daily age estimation. Daily age estimates for all three otolith pairs were significantly related to known age (r² ≥ 0.95), but the strongest relationship existed for measurements from sagittae (r² = 0.98) and the lapillus (r² = 0.98). Age prediction models all resulted in a slope near unity, indicating that ring deposition occurred approximately daily. Timing of ring formation varied among otolith types; sagitta approximately 3 days after hatch, lapillus 7 days after hatch (i.e., swim-up), and asteriscus 9 days after hatch. These results fill a gap in knowledge and can aid understanding of evolutionary processes as well as provide useful information for management and conservation.

Wildlife Biology 22:117 - 123 \| Abstract \| Download	2016-05-31	One key assumption often inferred with using radio-equipped individuals is that the transmitter has no effect on the metric of interest. To evaluate this assumption, we used a known fate model to assess the effect of transmitter type (i.e. tail-mounted or peritoneal implant) on short-term (one year) survival and a joint live–dead recovery model and results from a mark–recapture study to compare long-term (eight years) survival and body condition of ear-tagged only Ameri-can beavers Castor canadensis to those equipped with radio transmitters in Voyageurs National Park, Minnesota, USA. Short-term (1-year) survival was not influenced by transmitter type (wi  0.64). Over the 8-year study period, annual survival was similar between transmitter-equipped beavers (tail-mounted and implant transmitters combined; 0.76; 95% CI  0.45–0.91) versus ear-tagged only (0.78; 95% CI  0.45–0.93). Additionally, we found no difference in weight gain (t9  0.25, p  0.80) or tail area (t11  1.25, p  0.24) from spring to summer between the two groups. In contrast, winter weight loss (t22   2.03, p  0.05) and tail area decrease (t30   3.04, p  0.01) was greater for transmitter-equipped (weight   3.09 kg, SE  0.55; tail area   33.71 cm2, SE  4.80) than ear-tagged only (weight   1.80 kg, SE  0.33; tail area   12.38 cm2, SE  5.13) beavers. Our results generally support the continued use of transmitters on beavers for estimating demographic parameters, although we recommend additional assessments of transmitter effects under different environmental conditions.

We compared the effectiveness of three sampling techniques (small-mesh hoop nets, benthic trawls, boat-mounted electrofishing) for 30 species in the Green (WY, USA) and Kootenai (ID, USA) rivers by estimating detection probabilities (probability of detecting a species given its presence at a site). Electrofishing had the highest detection probabilities for most species, but hoop nets also had high detectability for several species (e.g., adult Burbot Lota lota, juvenile Northern Pikeminnow Ptychocheilus oregonensis). Benthic trawls had low detection probabilities for most fishes. Gear-specific effects were present for most species indicating large differences in gear efficacy among techniques. In addition to gear effects, habitat characteristics also influenced detectability of fishes. Most species-specific habitat relationships were idiosyncratic and reflected differences in the ecology of the species. Overall, this study provides important information on the effectiveness of various techniques targeting fish assemblages and will help improve future sampling efforts in coldwater river systems.

Canadian Journal of Fisheries and Aquatic Sciences. 76:1836-1844. \| Abstract	2019-09-30	Minimizing fishing impacts on seafloor ecosystems is a growing focus of ocean management; however, few quantitative tools exist to guide seascape scale habitat management. To meet these needs, we developed a model to assess benthic ecosystem impacts from fishing gear contact. The habitat impacts model is cast in discrete-time and can accommodate overlapping fisheries as well as incorporate gear-specific contact dynamics. We implemented the model in the North Pacific using fishing data from 2003 – 2017, estimating that habitat in 3.1% of the 1.2 million km2 study area was disturbed at the end of the simulation period. A marked decline in habitat disturbance was evident since 2010 attributable to a single regulatory gear change which lifted trawl gear components off the seafloor. Running scenarios without these gear modifications showed these policies may have contributed to a 24% reduction in habitat disturbance since their implementation. Ultimately, model outputs provide direct estimates of the spatial and temporal trends of habitat effects from fishing – a key component of regulatory policies for many of the world’s fisheries.

Rainbow Smelt (Osmerus mordax) and Alewife (Alosa pseudoharengus) are common prey fish species in lakes throughout North America either as native or non-native species. The establishment of Alewife in the 2000s in a lake with a native Rainbow Smelt population (Lake Champlain) presented an opportunity to study changes in the diet and trophic level of fish already established in the system. Using stable isotope analysis, we found that Alewife became a major component of predator diets, in particular of the diets of Atlantic Salmon (Salmo salar) and Walleye (Sander vitreus). Lake Trout (Salvelinus namaycush) consumed relatively few Alewives. For Walleye (the predator with both pre- and post-Alewife isotope ratios available), the δ15N values decreased significantly from the pre-Alewife period of the late 1990s, indicating that Walleye feed at lower trophic levels when Alewife are present. Predation on Alewife was correlated with the amount of spatial overlap of predators and prey. Our results show that the introduction of Alewife has altered the predator-prey linkages in Lake Champlain; alterations that can have major effects on food web structure and trophic cascades.

Transactions of the American Fisheries Society 145: 649-656. doi: 10.1080/00028487.2016.1143401 \| Abstract	2016-04-30	Timing of hatch in fish populations can be critical for first-year survival and, therefore, year-class strength and subsequent species interactions. We compared hatch timing, growth rates and subsequent mortality of age-0 Rainbow Smelt Osmerus mordax and Alewife Alosa pseudoharengus, two common open-water fish of northern North America. In our study site, Lake Champlain, Rainbow Smelt hatched almost a month earlier than Alewife (hatching began on 26 May for Rainbow Smelt and 20 June for Alewife). Abundance in the sampling area was highest in July for age-0 Rainbow Smelt and August for age-0 Alewife. Later-hatching individuals of both species grew faster than those hatching earlier (0.6 mm/d vs. 0.4 for Rainbow Smelt; 0.7 mm/d vs. 0.6 for Alewife). Mean mortality rate for age-0 Rainbow Smelt was 3.4%/d and for age-0 Alewife was 5.5%/d during the first 45 days of life. Alewife mortality rates did not differ with hatch timing but daily mortality rates of Rainbow Smelt were highest for earlier-hatching fish. Cannibalism is likely the primary mortality source for age-0 Rainbow Smelt in this lake. Therefore, hatching earlier may not be advantageous as the overlap of adult and age-0 Rainbow Smelt is highest earlier in the season. However, Alewife, first documented in Lake Champlain in 2003, may increase the mortality of age-0 Rainbow Smelt in the summer, which should favor selection for earlier hatching.

Conference on Computation and Sustainable Society 2018. \| Abstract	2018-07-31	We provide an exact and approximation algorithm based on dynamic programming and an approximation algo- rithm based on MIP for optimizing for the so-called dendritic connectivity on tree-structured networks in a multi-objective setting. Dentritic connectivity describes the degree of connectedness of a network. We con- sider different variants of dendritic connectivity to cap- ture both network connectivity with respect to long and short-to-middle distances. Our work is motivated by a problem in computational sustainability concerning the evaluation of trade-offs in ecosystem services due to the proliferation of hydropower dams throughout the Ama- zon basin. In particular, we consider trade-offs between energy production and river connectivity. River frag- mentation can dramatically affect fish migrations and other ecosystem services, such a navigation and trans- portation. In the context of river networks, different variants of dendritic connectivity are important to char- acterize the movements of different fish species and hu- man populations. Our approaches are general and can be applied to optimizing for dendritic connectivity for a variety of multi-objective problems on tree-structured networks.

Landscape Ecology 32: 2327-2336. \| Abstract	2017-09-30	Context: Efficient restoration of longitudinal river connectivity relies on barrier mitigation prioritization tools that incorporate stream network spatial structure to maximize ecological benefits given limited resources. Typically, ecological benefits of barrier mitigation are measured using proxies such as the amount of accessible riverine habitat. Objectives: We developed an optimization approach for barrier mitigation planning which directly incorporates the ecology of managed taxa, and applied it to an urbanizing salmon-bearing watershed in Alaska. Methods: A novel river connectivity metric that exploits information on the distribution and movement of managed taxon was embedded into a barrier prioritization framework to identify optimal mitigation actions given limited restoration budgets. The value of ecological information on managed taxa was estimated by comparing costs to achieve restoration targets across alternative barrier prioritization approaches. Results: Barrier mitigation solutions informed by life history information outperformed those using only river connectivity proxies, demonstrating high value of ecological information for watershed restoration. In our study area, information on salmon ecology was typically valued at 0.8-1.2M USD in costs savings to achieve a given benefit level relative to solutions derived only from stream network information, equating to 16-28% of the restoration budget. Conclusions: Investing in ecological studies may achieve win-win outcomes of improved understanding of aquatic ecology and greater watershed restoration efficiency.

In this article, we introduce conceptual modeling methods that incorporate expert ratings about a suite of properties of system components, including assessment of the state of knowledge, the strength of ecological impact, and the state of management or research attention devoted to a given component. Quantitative ratings of the properties of system components are subsequently used to prioritize model components objectively for research or management attention. Two case studies, one on plankton-herring-baleen whale dynamics and one on Chinook salmon strategic research planning, are presented to illustrate techniques. For example, in the Chinook salmon case study, participants constructed a prioritization score that identified system components rated as high ecological impact, but low state of knowledge and low state of management or research attention. By addressing gaps in both knowledge and attention, participants implemented a strategy for research planning that complemented existing Chinook salmon research and management in the study region. The case studies demonstrated that conceptual ecological models could be completed successfully with an economy of time. Conceptual modeling has been implemented across a range of disciplines and provides a useful tool that natural resource management and research groups can use to organize collaborative efforts and communicate research or management progress to stakeholders or funders.

DOI: https://doi.org/10.1016/j.biocon.2017.06.015 \| Abstract	2017-07-31	The remoteness of subarctic and arctic ecosystems no longer protects against invasive species introductions. Rather, the mix of urban hubs surrounded by undeveloped expanses creates a ratchet process whereby anthropogenic activity is sufficient to introduce and spread invaders, but for which the costs of monitoring and managing remote ecosystems is prohibitive. Elodea spp. is the first aquatic invasive plant to become established in Alaska and has potential for widespread deleterious ecological and economic impacts. A rapid eradication response with herbicides has been identified as the priority invasion control strategy. We conducted a multi-lake monitoring effort to assess collateral impacts from herbicide treatment for Elodea in high latitude systems. Variability in data was driven by seasonal dynamics and natural lake-to-lake differences typical of high latitude waterbodies, indicating lack of evidence for systematic impacts to water quality or plankton communities associated with herbicide treatment of Elodea. Impacts on native macrophytes were benign with the exception of some evidence for earlier onset of leaf senescence for lily pads (Nuphar spp.) in treated lakes. We observed a substantial increase in native flora richness after Elodea was eradicated from the most heavily infested lake, indicating potential for retention of native macrophyte communities if infestations are addressed quickly. While avoiding introductions through prevention may be the most desirable outcome, these applications indicated low risks of non-target impacts associated with herbicide treatment as a rapid response option for Elodea in high latitude systems.

DOI: https://doi.org/10.1139/cjfas-2015-0318 \| Abstract	2016-08-31	Missed counts are commonplace when enumerating fish passing a weir. Typically connect-the-dots linear interpolation is used to impute missed passage; however, this method fails to characterize uncertainty about estimates, and cannot be implemented when the tails of a run are missed. Here, we present a statistical approach to imputing missing passage at weirs which addresses these shortcomings, consisting of a parametric run curve model to describe the smoothed arrival dynamics of a fish population and a process variation model to describe the likelihood of observed data. Statistical arrival models are fit in a Bayesian framework and tested with a suite of missing data simulation trials and against a selection of Pacific Salmon (Oncorhynchus spp.) case studies from the Yukon River drainage, Alaska, U.S.A. When compared against linear interpolation, statistical arrival models produced equivalent or better expected accuracy and a narrower range of bias outcomes. Statistical arrival models also successfully imputed missing passage counts for scenarios where the tails of a run were missed.

Fisheries Management and Ecology 25: 296-303. \| Abstract	2018-07-31	The spawning migration travel times of chum salmon Oncorhynchus keta (Walbaum) fitted with gastrically implanted radio tags versus external spaghetti tags were tested over a short (≈60 river km) and long migration route (≈730 rkm) on the Koyukuk river, Alaska, USA. Using a novel application of statistical arrival curve models to infer travel times for uncaptured fish, migrations by chum salmon not directly handled during the study were also assessed. Results demonstrated negligible differences in travel times within migration routes between fish fitted only with spaghetti tags and fish fitted with radio tags, indicating low impacts on migration travel behavior associated with gastric tags once deployed. Conversely, travel times for unhandled fish as inferred by statistical arrival models may have been 12-24% shorter than those for fish captured with gillnets for tagging. These results suggest that if present, chum salmon migration behavior impacts may be more strongly associated with fish capture than tag deployment.

Methods in Ecology and Evolution. https://doi.org/10.1111/2041-210X.13079 \| Abstract	2019-01-31	1. Mixtures of DNA from multiple contributors present a novel opportunity to count individuals to inform fish and wildlife ecology. 2. We apply a likelihood based framework to estimate the number of contributors to a DNA mixture for ecological applications. We then assess the performance of DNA mixture estimation through a combination of simulation analyses, laboratory testing, and a field trial to estimate fish predation rates from stomach content analysis. 3. Simulations indicated reasonably sized genetic marker panels could estimate the number of contributors to mixtures comprised of up to 10 individuals, with potential to resolve larger mixtures with additional markers. Mixture estimates demonstrated robustness to common genotyping errors associated with fish and wildlife genetics applications. Laboratory trials demonstrated that DNA combined from multiple yellow perch (Perca flavescens) could be successfully genotyped with a 14-loci microsatellite panel and led to successful estimation for up to 5-contributor mixtures. Stomach content analysis with DNA mixtures indicated a 5-fold increase in estimated predation rates of yellow perch by largemouth bass (Micropterus salmoides) relative to conventional visual assessment of diet contents which can miss partially digested prey items. 4. DNA mixtures have potential to expand applications of count-based ecological analyses. Technical challenges in generating genotypes from DNA mixtures may initially limit their use, however, advances in next generation genotyping platforms are anticipated to surmount these obstacles. Chiefly, we envision opportunity for DNA mixtures to advance eDNA analysis beyond presence/absence based inference to enumeration of specimens.

Journal of Shellfish Research 36:341-351. https://doi.org/10.2983/035.036.0206 URL: http://www.bioone.org/doi/full/ \| Abstract	2017-08-31	Recognition of the global loss of subtidal oyster reefs has led to a rise in reef restoration efforts, including in the Gulf of Mexico. Reef restoration in the Gulf consists primarily of deploying hard substrate, and allowing oysters to recruit, grow, and proliferate, eventually building a living reef. Despite the large amount of resources devoted to the design and construction of oyster reefs, evaluation of the site prior to reef installation is often limited. Created reef success depends entirely on selecting a location that supports long-term oyster growth and survival, including the recruitment and survival of on-reef oysters. We examined oyster growth, mortality, condition and disease prevalence in different stocks of oysters located in protected cages, as well as oyster recruitment and mortality on experimental reef units in three different locations along the Louisiana Gulf coast in 2011 and 2012. Over a two-year period, our highest salinity site with the highest oyster growth rate in protected cages demonstrated the least likelihood for reef restoration success based on on-reef oyster population failure (high recruitment, 100% mortality). In contrast, our mid-salinity site with moderate oyster growth and on-reef recruitment had low and moderate recruitment and growth rates with low overall mortality, while the lowest salinity site exhibited extreme variability in all oyster responses on and off-reef due to one year of extended low salinity (< 2), and one year of above average salinity. The difference in oyster growth and survival rates between caged oysters and on-reef recruited oysters at each site clearly indicates that restoration suitability indices incorporating both oyster population dynamics and in-situ on-reef biotic and abiotic interactions are critical in better directing site selection for reef restoration efforts.

Wildlife Biology \| Abstract \| Download	2018-09-30	Surveillance for wildlife diseases is essential for assessing population dynamics of ungulates, especially in free-ranging populations where infected animals are difficult to sample. Chronic wasting disease (CWD) is an emerging infectious disease of concern because of the potential for substantial negative effects on populations of cervids. Variability in the likelihood that CWD is detected could invalidate traditional estimators for prevalence. In some instances, deer located after death cannot be tested for infectious diseases, including CWD, because of lack of availability or condition of appropriate tissues. We used various methods to detect infectious diseases that could cause mortality for deer Odocoileus spp. residing in Wind Cave National Park, South Dakota, USA, and we report survival estimates for animals in this population. We included 34 monthly encounters of deer resightings and 67 mortalities. We tested live deer by tonsillar biopsy for CWD and estimated pooled prevalence (mean ± SE) at 5.6 ± 3.0% over the three-year study. Live deer potentially had exposure to several infectious diseases, including bluetongue, epizootic hemorrhagic disease, bovine viral diarrhea, West Nile virus, and malignant catarrhal fever, but no apparent morbidity or mortality from those diseases. We tested survival and influence of covariates, including age and sex, using known-fate analysis in Program MARK. Those data best supported a model with time-invariant encounter probability and an annual survival of 72.8%. Even without direct pressure from hunting within the park, average life expectancy in this population was 3.2 years. Only 68% of mortalities contained sufficient material for CWD sampling (because of predation and scavenger activity) and >42% of these were CWD-positive. These findings underscore the possible biases in postmortem surveillance estimates of disease prevalence because of potential for subclinical infected animals to be removed by predators and not tested.

Spatial Ecology of Urban Striped Skunks (Mephitis mephitis) in the Northern Great Plains: A Framework for Future Oral Rabies Vaccination Programs. Urban Ecosystems 22:539-552. \| Abstract	2019-05-31	Few studies have investigated the ecology of urban striped skunks (Mephitis mephitis) despite their role as a primary rabies vector species paired with an ability to thrive in these landscapes. Information on home range, nightly movements, and habitat selection, is important for informing rabies management decisions such as the placement of oral rabies vaccine (ORV) baits and for management of the species. Our aim was to obtain baseline ecological information with an emphasis on spatial ecology of urban striped skunks in the Northern Great Plains region that is lacking in the literature. We used radio telemetry to track 22 (4 M, 18 F) skunks from September 2016 to November 2016 and March 2017 to November 2017. Size of home range using kernel density estimation with smoothing by least squares cross validation identified males (x ̅ = 4.36 km2, SE ± 0.79) had larger home ranges than females (x ̅ = 1.79 km2, SE ± 0.24). Female skunk home ranges differed by season with the largest home ranges found in summer 2017. However, rate of nightly movements (m/hr) among female skunks did not differ within seasons (x ̅ = 184.79 m/hr, SE ± 0.53). Moreover, we found no evidence that use-availability was associated with habitat type among female skunks. The strongest predictor of habitat use was distance to water sources with female skunks more likely to be found closer to this habitat type; however, we found no association of use with road factors and geographic location within the study area. Targeting ORV efforts in areas near water may be warranted, but considering differences in habitat selection for skunk in urban areas, we caution that ORV baiting programs may not be one-size-fits-all, and a framework for effective bait placement would be most successful with studies similar to ours conducted beforehand.

Wildlife Society Bulletin 40:217-223 \| Abstract \| Download	2016-06-30	In 2003, a reintroduction program was initiated at Badlands National Park (BNP), South Dakota, USA, with swift foxes (Vulpes velox) translocated from Colorado and Wyoming, USA, as part of a restoration effort to recover declining swift fox populations throughout its historical range. Estimates of age-speciﬁc survival are necessary to evaluate the potential for population growth of reintroduced populations. We used 7 years (2003–2009) of capture–recapture data of 243 pups, 29 yearlings, and 69 adult swift foxes at BNP and the surrounding area to construct Cormack–Jolly–Seber model estimates of apparent survival within a capture–mark–recapture framework using Program MARK. The best model for estimating recapture probabilities included no differences among age classes, greater recapture probabilities during early years of the monitoring effort than later years, and variation among spring, winter, and summer. Our top ranked survival model indicated pup survival differed from that of yearlings and adults and varied by month and year. The apparent annual survival probability of pups (0.47, SE ¼ 0.10) in our study area was greater than the apparent annual survival probability of yearlings and adults (0.27, SE ¼ 0.08). Our results indicate low survival probabilities for a reintroduced population of swift foxes in the BNP and surrounding areas. Management of reintroduced populations and future reintroductions of swift foxes should consider the effects of relative low annual survival on population demography.

Rybovich, M., La Peyre, M., Hall, S., La Peyre, J. 2016. Growth and mortality of spat, seed, and market-sized oyster at low salinities and high temperatures. Journal of Shellfish Research. \| Abstract	2016-10-31	Changes in the timing and interaction of seasonal high temperatures and low salinities as predicted by climate change models could dramatically alter oyster population dynamics. Little is known explicitly about how low salinity and high temperature combinations affect spat (< 25 mm), seed (25-75 mm), and market (> 75 mm) oyster growth and mortality. Using lab and field studies, this project quantified the combined effects of extremely low salinities (< 5 psu) and high temperatures (>30°C) on growth and survival of spat, seed, and market-sized oysters. In 2012 and 2013, hatchery-produced oysters were placed in open and closed bags at three sites in Breton Sound, LA, along a salinity gradient which typically ranges from 5 to 20 psu. Growth and mortality were recorded monthly. Regardless of size class, oysters at the lowest salinity site (annual mean = 4.8 psu) experienced significantly higher mortality and lower growth than oysters located in higher salinity sites (annual means = 11.1 and 13.0 psu); furthermore, all oysters in open bags at the two higher salinity sites experienced higher mortality, likely due to predation. To explicitly examine oyster responses to extreme low salinity and high temperature combinations, a series of laboratory studies were conducted. Oysters were placed in 18 tanks in a fully crossed temperature (25°C, 32°C) by salinity (1, 5, 15 psu) study with 3 replicates, and repeated twice for each oyster size class. Regardless of temperature, seed and market oysters held in low salinity tanks (salinity = 1 psu) experienced 100% mortality within seven days. In contrast, at 5 psu, temperature significantly affected the mortality rate; all size class oysters experienced greater than 50% mortality at 32°C, and less than 40% mortality at 25°C. In higher salinity tanks (15 psu), only market-sized oysters held at 32°C experienced significant mortality (> 60%). These studies demonstrate that high water temperatures (> 30°C) and low salinities (< 5 psu) negatively impact oyster growth and survival, and that high temperatures alone may negatively impact market-sized oysters. It is critical to understand the potential impacts of climate and anthropogenic changes on oyster resources in order to better adapt and manage for long-term sustainability.

Canadian Journal of Fisheries and Aquatic Sciences 76: 1862-1873. dx.doi.org/10.1139/cjfas-2018-0290 \| Abstract	2019-09-30	We conducted a comprehensive mark-recapture tagging study to examine the behavior and survival of spring run Chinook salmon (Oncorhynchus tshawytscha) returning to the Interior Columbia River Basin. Our study included adult salmon returning to the Upper Columbia and Snake Rivers, two fish populations that have been protected under the Endangered Species Act for greater than 15 years. This study was prompted by concern that pinnipeds present within the estuary and lower CR during spring may be detrimentally affecting the recovery of these salmon stocks. Over a five-year period we injected adult salmon with Passive Integrated Transponder Tags as they returned to the estuary. We used these data to fit a mixed effects logistic regression model and identify covariates that influence survival to Bonneville Dam (Rkm 235). Modelling indicated sea lion exposure, the abundance of adult shad (Alosa sapidissima) within the lower Columbia River, and whether or not fish had intact adipose fins all influenced survival. Survival ranged from 0.46 to 0.80 annually over the course of the study and was lowest during the last two years.

Canadian Journal of Fisheries and Aquatic Sciences 76:2215-2224. \| Abstract	2019-03-31	Pacific halibut (Hippoglossus stenolepis) bycatch limits many Alaska trawl fisheries and greatly concerns stakeholders from local communities and fisheries that rely on Pacific halibut. To reduce Pacific halibut mortality, Bering Sea trawlers that target flatfish have been developing expedited release procedures to sort Pacific halibut from catches earlier than current regulations allow, while continuing accurate bycatch accounting. We studied survival rates of released Pacific halibut from three trawlers by deploying accelerometer-equipped Popup Satellite Archival Tags (PSATs) on 160 fish handled under expedited procedures. PSATs recorded and transmitted two metrics indicating swimming activity for every two hours while attached to the fish for up to 60 days. Analysis of the resulting survival outcomes largely validated current survival estimation methods, based on structured viability assessments, and found longer fish length, shorter air exposure, and shorter trawl tow duration all improved predicted Pacific halibut survival. Differences in these results were detected between vessel trips and species targeted by trawling. PSATs provided detailed data from all tagged fish, while exposing fish to conditions experienced by normal releases.

In Georgia, the proportion of Whites, which have comprised the largest segment of the recreation resource user base, is declining while the share of other racial groups (i.e., Non-whites) is increasing. Fishery managers benefit by knowing if White anglers differ from Non-white anglers in attributes such as demographic characteristics and fishing behavior and preferences. In this study, we compared the racial differences on angling metrics and other attitudinal variables from an intensively managed fishery. There significant differences between user groups in many of the attributes measured. Differences in demographics, sportfish preference, and harvest-orientated behavior confirm that the White and Non-white anglers constitute two distinct segments of this fishery, and these findings, albeit from one study area, may be applicable to other similar fisheries.

DOI: 10.1111/eff.12407 \| Abstract	2018-09-30	Resource subsidies often have major consequences on recipient species and food webs. While invasive species are known to negatively affect some species and ecosystems, their influences on prey subsidies and effects on recipient consumers are unknown. The green alder sawfly (Monsoma pulveratum) is a recently introduced invasive wasp responsible for defoliating riparian thin-leaf alder (Alnus tenuifolia) stands across southcentral Alaska. To examine the effect of riparian alder defoliation by the larval green alder sawfly on the flow of terrestrial invertebrate prey subsidies to stream salmonids, we sampled 1) terrestrial invertebrate communities on riparian alder foliage, 2) their subsidies to streams, and 3) prey consumption by juvenile Coho Salmon (Oncorhynchus kisutch) along stream reaches with low and high densities of this invasive Hymenopteran. Sawfly biomass peaked mid-summer in all three categories—on riparian alder foliage, as terrestrial subsidies to streams, and ingested by juvenile Coho Salmon. Broader terrestrial invertebrate communities did not decline from sawfly defoliation; instead, invasive sawflies were supplemental prey for juvenile Coho Salmon mid-summer, on top of the background invertebrate subsidy. Our study showed that invasive green alder sawfly defoliation changed terrestrial prey subsidies for these stream fishes, as predicted. Considering that this study was conducted at the early stage of sawfly invasion, the loss of riparian alder is expected to have other ecological consequences that merit further investigation. However, in this case, invasive sawflies did not affect terrestrial subsidies to stream consumers in these study streams in southcentral Alaska.

Hydrobiologia 808:153-161. doi: 10.1007/s10750-017-3415-9 \| Abstract	2018-02-28	Developing effective monitoring methods for elusive, rare, or patchily distributed species requires extra considerations, such as imperfect detection. Although detection is frequently modeled, the opportunity to assess it empirically is rare, particularly for imperiled species. We used Pecos assiminea (Assiminea pecos), an endangered semi-aquatic snail, as a case study to test detection and accuracy issues surrounding quadrat searches. Quadrats (9 x 20 cm; n = 12) were placed in suitable Pecos assiminea habitat and randomly assigned a treatment, defined as the number of empty snail shells (0, 3, 6, or 9). Ten observers rotated through each quadrat, conducting 5-minute visual searches for shells. The probability of detecting a shell when present was 67.4% ± 3.0, but decreased with increasing litter depth and fewer shells present. The mean (± SE) observer accuracy was 25.5% ± 4.3%. Accuracy was positively correlated to number of shells in the quadrat and negatively correlated to number of times a quadrat was searched. The results indicate quadrat surveys likely underrepresent true abundance, but accurately determine presence or absence. Understanding detection and accuracy of elusive, rare, or imperiled species improves density estimates and aids in monitoring and conservation efforts.

Springer. \| Abstract	2016-12-31	Structured decision making (SDM) provides a framework for making sound decisions even when faced with uncertainty, and is a transparent, defensible, and replicable method used to understand complex problems. A hallmark of SDM is that it is a values-based system of decision-making and often includes participation from multiple stakeholders, helping to garner trust and ultimately result in a decision that is more likely to be implemented. The core steps of SDM are used to structure thinking about natural resource management choices, and include: 1) properly defining the problem and the decision context, 2) determining the objectives that help describe the aspirations of the decision maker, 3) devising management actions or alternatives that can achieve those objectives, 4) evaluating the outcomes or consequences of each alternative on each of the objectives, 5) modeling the system and evaluating trade-offs, and 6) implementing the decision. Participatory modeling for SDM includes creating qualitative and quantitative models of how the system works, providing data for these models, and eliciting expert opinion when data are unavailable. In these ways, SDM provides a framework for decision making in natural resources management that includes participation from stakeholder groups throughout the process, including the modeling phase.

Marine Ecology Progress Series, 614: 125-146. DOI: 10.3354/meps12888 \| Abstract	2019-04-30	Fish larvae depend on finding and capturing enough prey for rapid growth during the planktonic phase. The diet of many fish larvae is dominated by copepods, small crustaceans that are highly sensitive to hydrodynamic disturbances and possess strong escape responses. We examined how fish larvae with immature jaws, musculature and fins capture such evasive prey. The kinematics of feeding attempts by larval clownfish (Amphiprion ocellaris) on three developmental stages of copepod (Bestiolina similis) were investigated using high-speed videography. A stealthy approach brought the fish larva within ca. 1 mm of the copepod; shortest distances were observed in early larvae (1 5 days post-hatch [dph]) attacking immature copepods. Peak speeds during strikes increased with fish age and copepod developmental stage (150 to 250 mm s-1) with time to capture <8 ms on average. Most successful captures (70%) were of copepods that failed to initiate an escape response during the strike. If a copepod initiated an escape, capture success decreased to ca. 50% for nauplii and copepodites, and 25% for adults. Adult copepods were more likely to attempt an escape response than copepodites or nauplii. Prey stage and the interaction between strike distance and speed were the parameters that best fit a logistic regression model to the observed captures and escapes. The successful switch to larger and more evasive copepod prey by A. ocellaris larvae did not occur until 7 dph and coincided with ontogenetic changes (post-flexion) and a predatory strategy that included shorter approach phases and greater strike speeds.

Groundwater upwelling regulates thermal hydrodynamics and salmonid movements during high temperature events at a montane tributary confluence. Transactions of the American Fisheries Society doi.org/10.1002/tafs.10259 \| Abstract	2020-08-31	The Smith River is a popular recreational sport fishery in western Montana, but salmonid abundances there are thought to be limited by riparian land-use alterations, irrigation water withdrawals, and high summer water temperatures. We used integrated networks of temperature loggers, PIT-tag antenna stations, and in-situ temperature mapping to investigate thermal hydrodynamics and associated movements of PIT-tagged salmonids at the confluence of Tenderfoot Creek, a major, unaltered coldwater tributary of the Smith River. Contrary to expectations, Tenderfoot Creek itself was not used as a thermal refuge by salmonids during periods of high main-stem water temperatures; rather, its cool outflow into the Smith River was used instead. Mean outflow water temperatures were 2.9 °C lower than those of the Smith River during summer and ranged from 0.5 °C to 6.1 °C less. Moreover, measured and estimated temperatures in the outflow were cooler (by up to 2.8 °C) than in Tenderfoot Creek itself at times as a result of groundwater upwelling at the confluence. Detections of PIT-tagged fish in the thermal plume increased, especially at night, when daily mean water temperatures exceeded 20°C in the main stem Smith River; 4 times as many PIT-tagged fish were detected in the plume (<i>N = </i>52) than along the opposite bank (<i>N = </i>12), which ostensibly afforded better cover. Coldwater tributary confluences may provide superior thermal refuges for salmonids—cooler and more secure than the tributaries themselves—when water temperatures in river main stems are stressful.

Trophic pathways supporting juvenile Chinook and Coho salmon in the glacial Susitna River, Alaska: patterns of freshwater, marine, and terrestrial resource use across a seasonally dynamic habitat mosaic. Canadian Journal of Fisheries and Aquatic Sciences. \| Abstract	2016-08-31	Contributions of terrestrial, freshwater, and marine-derived prey resources to stream fishes vary over time and space, altering the energy pathways that regulate production. In this study we determined large-scale use of these resources by juvenile Chinook and Coho salmon (Oncorhynchus tshawytscha and O. kisutch) in the glacial Susitna River, Alaska. We resolved spatial and temporal trophic patterns among multiple macrohabitat types along a 97-km segment of the river corridor via stable isotope and stomach content analyses. Juvenile salmon were largely supported by freshwater-derived resources, and secondarily by marine and terrestrial sources. The relative contribution of marine-derived prey to rearing salmon was greatest in the fall within off-channel macrohabitats, whereas the contributions of terrestrial invertebrate prey were generally greatest during mid-summer, across all macrohabitats. No longitudinal (upstream-downstream) diet pattern was discernable. These results highlight the large-scale spatial and seasonal patterns of energy flow and the dynamic interplay of pulsed marine and terrestrial prey subsidies to juvenile Chinook and Coho salmon in a large, complex, and relatively pristine glacial river.

American Midland Naturalist 175:113-119. \| Abstract	2016-01-31	Eastern red cedar (Juniperus virginiana) is a fire-intolerant tree species that has been invading and altering grassland ecosystems throughout the American Great Plains and Midwest. Many land managers are interested in removing eastern red cedar to restore native grasslands. As a metric of habitat health, we surveyed small mammals using mark-recapture methods in eastern red cedar forest and 5 other habitats common to the Ozark region. We conducted over 7,000 trap-nights and captured 271 individuals belonging to 9 species, primarily Peromyscus spp., 475 times. The small mammal species composition in eastern red cedar forest was comparable to local mixed oak forests but lower than warm-season grasslands and oldfields. We encountered no small mammal species endemic to eastern red cedar forest. We found that eastern red cedar forest had no unique species and a less diverse small mammal community than the grasslands it replaced. Restoring former grasslands invaded by eastern red cedar should increase small mammal species diversity at the stand scale.

DOI: https://doi.org/10.3996/112014-JFWM-083 \| Abstract	2015-12-31	The efficacy of fish habitat conservation in land planning processes in Alaska is often constrained by the extent of current knowledge of fish distributions and habitat use. In response to requests for information from land and salmon resource management stakeholders regarding Auke Lake sockeye salmon (Oncorhynchus nerka) status and life history, we examined the prespawning movements and spawning distribution of adult sockeye salmon to provide ecological information needed for Auke Lake watershed management. We used radiotelemetry to track the movements of 80 fish in the Auke Lake watershed during 2012. The prespawning distribution of the fish was not random, indicating five spatially and temporally distinct high-use staging areas within the lake. The Auke Lake sockeye salmon population was dominated by stream-spawning fish (98.5%), with minimal lakeshore spawning (1.5%) observed in association with a small intermittent tributary of the lake. The prespawning distribution patterns identified in this study corroborate observations from Auke Lake 20 y ago, indicating consistent habitat use patterns by sockeye salmon in the lake. Telemetry data also indicate 12% of sockeye salmon expired in Auke Lake without spawning and that 14% of stream-spawning fish were preyed upon by black bear (Usrus americanus). The prespawning and spawning behavior by Auke Lake sockeye salmon suggest that discrete lake staging areas and stream spawning beds are important candidate habitats for protection during the land planning process for shoreline development surrounding the lake.

Environmental Biology of Fishes 99:753-760 . \| Abstract	2016-08-31	Research into the effects of shade on reservoir fish assemblages is lacking, with most such efforts focused on streams. Unlike streams, the canopy in reservoirs is restricted to the shoreline, and may not have the influential effect reported in streams. We compared fish assemblages between shaded and unshaded locations in a shallow reservoir. Overall species richness (gamma diversity) was higher in shaded sites, and fish assemblage composition differed between shaded and unshaded sites. Average light intensity was 66% lower in shaded sites, but average temperature and dissolved oxygen were < 5% lower. Unlike streams where shade can have large effects on water physicochemistry, in reservoirs shade-related differences in fish assemblages were due principally to differences in light intensity. Diversity in light intensity and spectral composition in shaded and unshaded sites can create diverse mosaics of light-based habitats that enhance species assemblages.

Transactions of the American Fisheries Society 145: 903-912. \| Abstract	2016-06-30	Stonecats (Noturus flavus, Rafinesque 1818) in Vermont fit into a rare distribution pattern, as designated by Rabinowitz, because their known distribution is limited to two systems, the LaPlatte and Missisquoi rivers. Here we focus on Stonecats in the LaPlatte River to predict the stability of the population. In 2012, 2013, and 2014 we captured, PIT tagged (> 90 mm total length), and VIE marked all Stonecats collected using backpack electrofishing. A total of 1671 Stonecats was captured, and of those, 1252 were PIT tagged. Only 12% (N=156) of the PIT tagged fish were recaptured and only 22 were recaptured more than one time. We used the Pradel model in Program MARK to estimate the survival and seniority of Stonecats and these values were used to derive lambda (λ), the population rate of change. We ran a total of 64 models in our candidate set with the following covariates: total length, maximum temperature, season, maximum discharge, and area sampled. Model results estimated that survival was highest in the spring, and increased with increasing total length of individuals. We also estimated increases in capture probability with increasing area sampled. We derived an annual λ of 0.9826, which indicates a slightly decreasing population. With only three years of data and a low recapture rate, our estimate has some uncertainty. Although the population could be declining at a slow rate, we have provided insight into population parameters that were otherwise unknown.

North American Journal of Fisheries Management 38:1316–1323. DOI:10.1002/nafm.10230 \| Abstract	2018-10-31	Little is known about Stonecat (Noturus flavus) populations, especially in the Northeastern United States, where these madtoms are at the edge of their range. In Lake Champlain tributaries, Stonecats are listed as endangered in Vermont, but not in New York. Here we describe the growth of Stonecats in two tributaries to Lake Champlain, one in Vermont and one in New York. We also compared the growth of Stonecats in these waters to results from other locations near the middle of their distribution. Stonecats in the Great Chazy River, NY were larger at ages 1-3, but smaller at age 5, than Stonecats from the LaPlatte River, VT. Stonecats in Lake Champlain tributaries were generally larger at age than those from the middle of their range, except for those from Lake Erie. Lake Champlain Stonecats appear to reach maturity by age 3, though future research that directly estimates age at maturity would be more informative. These results expand the literature that lacks information about growth of this species while also providing specific information needed to manage this and other fishes in Lake Champlain tributaries.

Transactions of the American Fisheries Society 145:1100-1121. \| Abstract \| Download	2016-08-31	Sixteen darter species, including the federally endangered Boulder Darter Etheostoma wapiti, are known to occur in the Elk River, a large, flow-regulated Tennessee River tributary in Tennessee and Alabama. Since the construction of Tims Ford Dam (TFD) in 1970, habitat modification caused by cold, hypolimnetic water releases and peak-demand hydropower generation have contributed to population declines and range reductions for numerous aquatic species in the mainstem Elk River. We developed multi-species occupancy models to determine the influence of site-, habitat-, and species-level characteristics on darter occurrence using presence-absence data for 15 species collected from 39 study reaches. Modeling results indicated that the large river obligate species, such as Boulder Darters, were 7.53 times more likely to occur for every 37 km increase in downstream from TFD. In contrast, small stream and cosmopolitan species were 2.04 and 1.82 times less likely, respectively, to occupy stream reaches for every 37 km downstream from TFD. The probability of occurrence for darter species also was strongly and negatively related to the absence of cobble and boulder substrates and the presence of high silt levels, particularly for species that require boulder substrates during spawning. Although total darter species richness was similar across all 39 sample sites, the composition of darter assemblages varied substantially among locations, presumably owing, in part, to species-specific habitat affinities and hydrothermal conditions. Results from this study provide a baseline for managers to assess future changes in the status and distribution of darter species following recent operational changes at TFD.

North American Journal of Fisheries Management. doi.org/10.1002/nafm.10492 \| Abstract	2020-07-31	Introduced Lake Trout <i>Salvelinus namaycush</i> threaten native Yellowstone Cutthroat Trout <i>Oncorhynchus clarkii bouvieri</i> in Yellowstone Lake, Yellowstone National Park, where gill nets have been used to suppress subadult and adult Lake Trout since 1995. However, survival of embryonic and larval life history stages can have profound effects on population dynamics of Lake Trout. Inducing additional mortality at those stages, especially if used in concert with intensive gillnetting of older fish, could enhance overall suppression efforts. Therefore, we conducted controlled field experiments at Yellowstone Lake to systematically evaluate the effects of sediment deposition and ground Lake Trout carcass deposition on Lake Trout embryos in prepositioned incubators. Sediment deposition caused dissolved oxygen concentrations to decline below lethal levels for a prolonged period (92 d) overwinter. Embryo mortality among overwintering incubators varied from 97 ± 5.3% at the substrate surface to 100 ± 0.0% 20 cm below the substrate surface. Decomposition of ground carcass material on spawning sites caused dissolved oxygen concentrations to decline to lethal levels (<3.4 mg/L) for about 9 days following biomass application rates of 14 and 28 kg/m2 in treatment plots. Exposure to ground carcass material resulted in 100 ± 0.0% (mean ± SE) embryo mortality at the substrate surface and within interstices 20 cm below the surface in 14 and 28 kg/m2 biomass treatments. Embryo mortality was probably caused by hypoxic conditions within substrates in both experiments. The deposition of sediment and ground Lake Trout carcass material on Lake Trout spawning sites in Yellowstone Lake could provide an additional source of mortality in ongoing Lake Trout suppression efforts. These methods may also be beneficial in other systems when incorporated in an integrated pest management approach (IPM) targeting multiple life history stages of invasive freshwater fish.

Journal of the Southeast Association of Fish and Wildlife Agencies 3:233-242 \| Abstract	2016-03-31	The loss of historic ecosystem conditions has led forest managers to implement woodland and savanna ecosystem restoration on a landscape scale (≥10,000 ha) in the Ozark Plateau of Arkansas. Managers are attempting to restore and conserve these ecosystems through the reintroduction of disturbance, mainly short-rotation early-growing-season prescribed fire. Short-rotation early-growing season prescribed fire in the Ozarks typically occurs from immediately before bud-break, through bud-break and before leaf-out, and fire events occur on a three to five year interval. We examined short-rotation early-growing season prescribed fire as a restoration tool on vegetation characteristics. We collected vegetation measurements at 70 locations annually from 2011 to 2012 in and around the White Rock Ecosystem Restoration Area (WRERA), Ozark-St. Francis National Forest, Arkansas, USA and used generalized linear models to investigate the impact and efficacy of prescribed fire on vegetation structure. We found the number of large shrubs (>5 cm base diameter) decreased and small shrubs (<5 cm ground diameter) increased with prescribed fire severity. We found that horizontal understory cover from ground level to 1 m in height increased with time since prescribed fire and woody ground cover decreased with the number of prescribed fire treatments. Using the LANDFIRE datasets at the landscape scale, we found that since the initiation of a short-rotation early-growing season prescribed fire management regime, canopy cover has not reverted to levels characteristic of woodlands and savannas or reached restoration objectives over large areas. Without greater reductions in canopy cover and increases in canopy cover heterogeneity, advanced regeneration will be limited in success, and woodland and savanna conditions will not return soon or to the extent desired.

PLoS ONE 11(1):e0147317. \| Abstract	2016-01-31	Landscape scale short-rotation early-growing season prescribed fire in upland hardwood forests represents a recent shift in management strategies across eastern upland forests. It is a departure from stand scale management regimes to landscape scale (>10 000 ha) management regimes. This being so, considerable commitments and resources are being made to this management strategy and the effects on wildlife in upland forests, especially those dominated by hardwood canopy species, are relatively unknown. We initiated this study to assess whether this management strategy affects eastern wild turkey reproductive ecology on the White Rock Ecosystem Restoration Area of the Ozark-St. Francis National Forest. We marked 67 wild turkey hens with 110 g Global Positioning System (GPS) Platform Transmitting Terminals in 2012 and 2013 on the WRERA to examine nest-site selection and estimate nest survival. We estimated nest survival and nest-site selection of wild turkey in forest units managed with short-rotation early-growing season prescribed fire (treated) and units absent of prescribed fire (untreated). We then compared these estimates to determine any differences in nest survival and nest-site selection in treated and untreated units. We found that nest survival was slightly higher in treated units than untreated but not significantly greater (S = 0.24 [0.13, 0.39], S = 0.2 [0.09, 0.37] respectively). We also found that wild turkey in treated units selected nest-sites based on different characteristics than in untreated units. In treated units wild turkey selected nest-sites with less visual concealment from 1 to 2 m in height, fewer large trees (>20 cm DBH), more grass ground cover, and more open canopies than random sites while wild turkey in untreated units did not select for these characteristics. In untreated units wild turkey selected nest-sites that were closer to roads than random sites while wild turkey in treated units did not select for this characteristic. In both treated and untreated units wild turkey selected nest-sites with more visual concealment from 0 to 1 m in height and more woody stem ground cover than random sites. In conclusion, wild turkey nest-survival and some nest-site characteristics are likely improved by short-rotation early-growing season prescribed fire, but for significant benefits to be realized managers will need to continue the commitment to the landscape scale management strategy.

We evaluated the effects of various external factors on the population numerical abundance of curimba Prochilodus lineatus at five sites of the remnant floodplain of the Upper Paraná River, Brazil, over a 19-year period. Panel data analysis, with the time series of each site as a panel, was applied to examine the structure of temporal and spatial abundance while controlling auto-regressive processes and spatial heterogeneous variances that often obscure relationships. As sources of population variation we considered predation, competition, selected abiotic variables (water pH, temperature, Secchi depth, and specific conductance), construction of a dam upstream of the study area, water level and flood intensity during the spawning period. We found that i) biological interactions (predation and competition) were not significantly related to variations in P. lineatus abundance; ii) specific conductance was a space indicator of abundance, apparently linked to the biology of the species (this variable separated lentic water bodies from rivers); iii) intensity of floods determined inter-annual variation in abundances; and iv) Porto Primavera Reservoir (located upstream from the study area) negatively impacted the abundances at sites in the floodplain directly affected by discharges from the dam. Panel data analysis was a powerful tool to predict changes in fish abundance. Use of this tool identified the need for intense flooding (river levels above 450 cm) to maintain high abundances of P. lineatus and those species with similar life strategy in the upper Paraná River.

Western North American Naturalist79:551-565. \| Abstract \| Download	2019-12-31	Since 1993, elk (Cervus canadensis nelsoni) abundance in the Black Hills of South Dakota has been estimated using a detection probability model previously developed in Idaho, though it is likely biased because of a failure to account for visibility biases under local conditions. To correct for this bias, we evaluated the current detection probability across the Black Hills during January and February 2009–2011 using radio-collared elk. We used logistic regression to evaluate topographic features, habitat characteristics, and group characteristics relative to their influence on detection probability of elk. Elk detection probability increased with less vegetation cover (%), increased group size, and more snow cover (%); overall detection probability was 0.60 (95% CI 0.52–0.68), with 91 of 152 elk groups detected. Predictive capability of the selected model was excellent (ROC = 0.807), and prediction accuracy ranged from 70.2% to 73.7%. Cross-validation of the selected model with other population estimation methods resulted in comparable estimates. Future applications of our model should be applied cautiously if characteristics of the area (e.g., vegetation cover >50%, snow cover >90%, group sizes >16 elk) differ notably from the range of variability in these factors under which the model was developed.

Marine Ecology. 15pp IP- 068594. https://doi.org/10.1111/maec.12412 \| Abstract \| Publisher Website	2017-04-30	Grande Riviere beach, on the island of Trinidad, supports the largest nesting population of leatherback turtles in the Caribbean region. Throughout the nesting season, nests are naturally disturbed by newly nesting females, resulting in egg breakage and loss of some nest viability. This environment is ideal for the growth and proliferation of microorganisms. The range of bacterial flora present in beach sand and egg shells was examined, with emphasis on bacteria that may pose a threat to public and animal health. The extent to which the bacterial load and genera on the beach changed throughout the season was also assessed. Twenty-five genera were identified, with Pseudomonas spp. found to be the most predominant environmental bacteria. Four genera identified possess zoonotic potential, while five additional genera are known to be of public and animal health significance. Distinct shifts in the density and distribution of bacteria were observed along the beach from early to peak nesting season. Shifts were seen across heavily traversed zones, thus highlighting the potential exposure threats posed to beach visitors and animals alike. Further studies aimed at speciating this population of bacteria, as well as isolating potential fungal pathogens may mitigate this threat. Identification of bacterial agents that are specifically pathogenic to leatherback turtles, turtle eggs, hatchlings and those who may interact with these animals will serve to enhance and guide efforts to better conserve this species and protect the health of all who visit this ecologically significant site.
Pfrimmer, J., Gigliotti, L., Stafford, J., Schumann, D., & Bertrand, K. (2017). Motivations for enrollment into the Conservation Reserve Enhancement Program in the James River Basin of South Dakota. Human Dimensions of Wildlife, 22(4):382-389. \| Abstract	2017-07-31	Landowner perceptions of conservation programs are highly complex, which complicates recruitment to and satisfaction with available programs. The Conservation Reserve Enhancement Program (CREP) targets high-priority conservation needs (e.g., water quality, wildlife habitat) by paying landowners an annual rental rate to remove environmentally sensitive or agriculturally unproductive lands from rowcrop production and to implement conservation practices on these lands. Herein, we describe the motivations of South Dakota landowners in the James River Basin for enrolling in the CREP. All 517 newly-enrolled landowners were mailed a questionnaire in 2014, measuring participant demographics, behaviors, opinions and motivations (60% response rate). We evaluated ten motivations for enrollment in CREP and used a cluster analysis to identify three unique respondent orientations (wildlife enhancement, financial incentive, and environmental concern). Understanding landowner enrollment decision criteria will advance strategies to increase participation and satisfaction in future platforms.

Restoration Ecology https://doi.org/10.1111/rec.13244 \| Abstract \| Publisher Website	2020-11-30	A considerable amount of resources have been invested in ecological restoration projects across the globe to restore ecosystem integrity. These restoration strategies are often diverse and have been met with mixed success. In this paper, we describe the Chinook salmon (<i>Oncorhynchus tshawytscha</i>) decision-support models developed by the Central Valley Project Improvement Act Science Integration Team as part of a larger structured decision making effort aimed at maximizing natural adult production of Chinook salmon in California’s Central Valley, USA. We then describe the decision analytic tools the stakeholder group used to solve the models and explore model results, including stochastic dynamic programming, forward simulation, proportional scoring, relative loss, expected value of perfect information, response profile analyses, and indifference curves. Using these tools, the stakeholder group was able to develop and quantitatively evaluate restoration strategies for multiple Chinook salmon runs simultaneously, a first for the restoration program. Furthermore, information uncovered during this process was then used to direct efforts towards targeted research/monitoring to reduce critical uncertainties and make better restoration decisions moving forward. The decision sciences have established a wide range of analytical tools and approaches to simplify complex problems into key components, and we believe the concepts described in this paper are of great interest to many restoration practitioners that undoubtedly face similar difficulties when implementing restoration strategies for complex systems.

Tagging effects of passive integrated transponder and visual implant elastomer on the small-bodied White Sands pupfish (Cyprinodon tularosa). Journal of Fisheries Research (online publication completed 24 September 2017); https://doi.org/10.1016/j.fisheries.2017.08.019. \| Abstract	2017-09-30	One of the greatest limiting factors of studies designed to obtain growth, movement, and survival in small-bodied fishes is the selection of a viable tag. The tag must be relatively small with respect to body size as to impart minimal sub-lethal effects on growth and mobility, as well as be retained throughout the life of the fish or duration of the study. Thus, body size of the model species becomes a major limiting factor; yet few studies have obtained empirical evidence of the minimum fish size and related tagging effects. The probability of surviving a tagging event was quantified in White Sands pupfish (Cyprinodon tularosa) across a range of sizes (19-60 mm) to address the hypothesis that body size predicts tagging survival. We compared tagging related mortality, individual taggers, growth, and tag retention in White Sands pupfish implanted with 8-mm passive integrated transponder (PIT), visual implant elastomer (VIE), and control (handled similarly, but no tag implantation) over a 75 d period. Initial body weight was a good predictor of the probability of survival in PIT- and VIE-tagged fish. As weight increased by 1 g, the fish were 4.73 times more likely to survive PIT tag implantation compared to the control fish with an estimated suitable tagging size at 1.1 g (TL: 39.29 ± 0.41 mm). Likewise, VIE-tagged animals were 2.27 times more likely to survive a tagging event compared to the control group for every additional 1 g with an estimated size suitable for tagging of 0.9 g (TL: 36.9 ± 0.36 mm). Growth rates of PIT- and VIE-tagged White Sands pupfish were similar to the control groups. This research validated two popular tagging methodologies in the White Sands pupfish, thus providing a valuable tool for characterizing vital rates in other small-bodied fishes.

Blood plasma samples were analyzed for metrics related to nutritional and osmotic status, and samples of white muscle tissue collected from recent mortalities at weirs were analyzed for proximate constituents. Female kelts from the Situk River had significantly higher plasma cholesterol, triglycerides, glucose and calcium concentrations, all of which suggested higher lipid and energy stores. Additional support for energy limitation in kelts was provided by evaluating the presence of detectable proteins in the plasma. Most all kelts sampled from the Situk River populations had detectable plasma proteins, in contrast to kelts sampled from the Clearwater River tributary populations where 27 % of kelts from one tributary, and 68 % of the second tributary were below the limits of detection.We found proximate constituents of kelt mortalities were similar between the Situk and Clearwater River populations, and the lipid fraction of white muscle averaged 0.1 and 0.2 %. Our findings lend support to the hypothesis that energetic limitations likely affect post-spawn survival in the Clearwater River kelts.

Transactions of the American Fisheries Society 148:35-47. \| Abstract	2019-01-31	A history of overexploitation and industrialization of riverine habitats has impacted Shortnose Sturgeon Acipenser brevirostrum, leading this species to be one of the earliest listed under the U.S. Endangered Species Act. Presently, understanding spatial ecology of Shortnose Sturgeon is based on observations from a limited number Atlantic coastal rivers. To better understand Shortnose Sturgeon in the Hudson River in NY, USA, we used acoustic telemetry to characterize seasonal habitat use and to identify regions of the river where seasonal sturgeon activity occurred. From 2012-2016, 101 adult fish were tagged and tracked from 2012-2016 and sturgeon detection per unit effort (a metric of fish observation standardized by search effort) was evaluated against benthic habitat variables using generalized additive regression models. Models indicated strong habitat associations in the Spring season defined by gravel dominated substrates and specific depth ranges, presumably associated with spawning activity. During Summer, sturgeon were more dispersed associating with muddy habitats, whereas, in Fall/Winter sturgeon congregated in specific regions of the river. These data demonstrate river use and habitat associations vary seasonally and identify important areas for managing overlap between seasonal sturgeon habitat use and human activity on the river.

Ecology and Evolution 8:8508-8522. doi: 10.1002/ece3.4349. \| Abstract \| Publisher Website	2018-07-31	Understanding the degree of intraspecific variation within and among populations is a key aspect of predicting the capacity of a species to respond to anthropogenic disturbances. However, intraspecific variation is usually assessed at either limited temporal, but broad spatial scales or vice versa, which can make assessing changes in response to long-term disturbances challenging. We evaluated the relationship between the longitudinal gradient of changing flow regimes and land use/land cover patterns since 1980 and morphological variation of Guadalupe Bass Micropterus treculii throughout the Colorado River Basin of central Texas. The Colorado River Basin in Texas has experienced major alterations to the hydrologic regime due to changing land and water-use patterns. Historical collections of Guadalupe Bass prior to rapid human-induced change present the unique opportunity to study the response of populations to varying environmental conditions through space and time. Morphological differentiation of Guadalupe Bass associated with temporal changes in flow regimes and land use/land cover patterns suggests that they are exhibiting intraspecific trait variability, with contemporary individuals showing increased body depth, in response to environmental alteration through time (specifically related to an increase in herbaceous land cover, maximum flows, and the number of low pulses and high pulses). Additionally, individuals from tributaries with increased hydrologic alteration associated with urbanization or agricultural withdrawals tended to have a greater distance between the anal and caudal fin. These results reveal trait variation that may help to buffer populations under conditions of increased urbanization and sprawl, human population growth, and climate risk, all of which impose novel selective pressures, especially on endemic species like Guadalupe Bass. Our results contribute an understanding of the adaptability and capacity of an endemic population to respond to future changes expected based on demographic or climatic projection.

U.S. Department of Interior, Fish and Wildlife Service, Cooperator Science Series FWS/CSS-125-2017, Washington, D.C. \| Abstract \| Download	2017-08-31	The Colorado River Basin in Texas has experienced major alterations to its hydrologic regime due to changing land and water use patterns. These anthropogenic influences on hydrologic variability have had major implications for riparian and aquatic ecosystems and the species dependent upon them. However, impacts are often assessed at a limited temporal and spatial scale, tending to focus on relatively short and discrete periods or portions of a river basin. It is not clear how basin-wide alterations occurring over decades affect species. Guadalupe Bass Micropterus treculii are endemic to central Texas and are typically associated with shallow runs and riffles in small streams. However, Guadalupe Bass are found throughout the Colorado River Basin, including the mainstem portion of the lower river downstream of the city of Austin where they support a popular fishery. Because Guadalupe Bass exist across a wide range of stream orders within the basin, it is unclear whether populations respond similarly to anthropogenic disturbances or to conservation and restoration activities. Therefore, our objectives were to: 1. Assess the effects of urbanization and hydrology on the population structure and dynamics of Guadalupe Bass. 2. Evaluate the effects of environmental gradients on ecomorphological variation in Guadalupe Bass populations across multiple spatial scales. 3. Describe the life history, habitat use, and behavior of the Guadalupe Bass population in the lower Colorado River and compare it to populations in more “typical” habitats. Results contribute to an understanding of the response of Guadalupe Bass to anthropogenic disturbances, including increased urbanization in central Texas and further assist in the conservation of the species. The ability of the population to not only persist, but flourish downstream of a heavily populated urban area presented a unique opportunity to investigate a native species response to anthropogenic disturbance. This research revealed differences in Guadalupe Bass habitat associations and movements, contrasts in age and growth, and morphological variation across a gradient of disturbance throughout the Colorado River Basin. Results of this work provide information on the potential effects of human population growth and increased water withdrawals on Guadalupe Bass populations. Additionally, this work adds to an understanding of the unique Guadalupe Bass population found in the lower Colorado River and how it differs from upstream tributary populations. Gathering additional population-level information facilitates conservation actions critical to preserving preferred habitat and promoting growth rates for Guadalupe Bass in streams of different sizes and flow conditions while highlighting interpopulation differences that may warrant consideration for stocking programs and other management strategies. Key findings of this study were: • The similarity in response of growth rates to streamflow throughout the Colorado Basin suggests phenotypic plasticity in this trait rather than population-specific adaptations. • Reductions in streamflows in the Colorado River Basin, whether due to increased frequency of drought or increased anthropogenic water withdrawal, will likely result in lower Guadalupe Bass growth rates with the potential to impact the structure of populations. • Growth and recruitment showed a positive correlation with increased baseflows and mean monthly flows; however, continued assessment is necessary to determine a true relationship. • We documented morphological divergence among Guadalupe Bass populations in response to spatial and temporal environmental variation. These ecomorphological differences among populations provide insight into the ability of Guadalupe Bass to respond to the differing in-stream habitat and flow conditions between small ‘typical’ tributary systems and the mainstem Colorado River. • Morphological variation may be a population-level adaptation that potentially needs to be taken into consideration when choosing broodstock to maximize stocking success within a system. Understanding the morphological differences between Guadalupe Bass populations in response to local conditions could improve the success of restoration and supplemental stocking programs, especially in the ever-changing landscape of central Texas. • We established a baseline for understanding the morphological response of Guadalupe Bass to increased population growth and the threats posed by increased water withdrawals and impervious surface. • The mainstem population of Guadalupe Bass was generally more mobile, and more responsive to changes in streamflow, than tributary populations. The observed differences could influence the response of Guadalupe Bass populations to conservation and management actions, such as habitat restoration efforts. • Continued monitoring of recruitment and angler exploitation may be beneficial to identify any changes that could negatively impact the population. Conservation initiatives solely focused on physical instream or riparian habitat are unlikely to be as beneficial to Guadalupe Bass as those focused on restoring or maintaining adequate streamflow.

Species distribution changes under alternative landscape futures: Using a scenario framework to identify drivers and consequences of landscape change on wildlife in New England. Frontiers in Ecology and Evolution 8:164. doi: 10.3389/fevo.2020.00164. \| Abstract \| Download \| Publisher Website	2020-06-30	In an era of rapid climate and land transformation, it is increasingly important to understand how future changes impact natural systems. Scenario studies can offer the structure and perspective needed to understand the impacts of change and help inform management and conservation decisions. We implemented a scenario-based approach to assess how two high impact drivers of landscape change influence the distributions of managed wildlife species (<i>n</i> = 10) in the New England region of the northeastern United States. We used expert derived species distribution models (SDMs) and scenarios developed by the New England Landscape Futures Project (NELFP) to estimate how species distributions change under various trajectories (<i>n</i> = 5) of landscape change. The NELFP scenarios were built around two primary drivers – Socio-Economic Connectedness (SEC) and Natural Resource Planning and Innovation (NRPI) – and provide plausible alternatives for how the New England region may change over 50 years (2010–2060). Our models generally resulted in species occurrence and richness declines by 2060. The majority of species (7 of 10) experienced declines in regional occurrence for all NELFP scenarios, and one species experienced a projected increase in mean regional occurrence for all scenarios. Our results indicate that the NRPI and SEC drivers strongly influenced projected distribution changes compared to baseline projections. NRPI had a greater impact on distribution change for five species (coyote, moose, striped skunk, white-tailed deer, and wild turkey), while SEC had a greater impact on four species (American black bear, bobcat, raccoon, and red fox); one species (gray fox) was equally influenced by both NRPI and SEC. These results emphasize the importance of integrating both natural resource planning and socio-economic factors when addressing issues of distribution change and offer insights that can inform proactive management and conservation planning.

Understanding where species are likely to occur now and in the future can help identify areas that are resistant to change over time and guide conservation planning. We estimated changes in species distribution patterns and spatial resistance in five future scenarios for the New England region of the northeastern United States. We present scenario-specific distribution change maps for nine harvested wildlife species, identifying regions of increasing, decreasing, or stable habitat suitability within each scenario. Next, we isolated areas where species occurrence probability is high (p > 0.7) and resistant to change across all future scenarios. Resistance was also evaluated relative to current land protection to identify patterns in and out of Protected Areas (PAs). Generally, species distributions declined in area over the 50-year assessment period (2010–2060), with the greatest average declines occurring for moose (-40.9%) and wild turkey (-22.1%). Species resistance varied considerably across the region, with coyote demonstrating the highest average regional resistance (91.81% of the region) and moose demonstrating the lowest (0.76% of the region). At the state level, average focal species resistance was highest in Maine (the largest state) and lowest in Massachusetts. Many of the focal species showed high overlap in resistance and land protection. Coyote, white-tailed deer, and black bear had the highest probability of resistance, given protection, while moose and wild turkey had the highest probability of protection, given resistance. Overall, relatively small portions of New England—ranging between 0.25% and 21.12%–were both protected and resistant for the focal species. Our results provide estimates of resistance that can inform conservation planning for commonly harvested species that are important ecologically, economically, and culturally to the region. Expanding protected area coverage to include resistant areas may provide longer term benefits to these species.

Global Ecology and Conservation 21:e00853. \| Abstract \| Download \| Publisher Website	2020-03-31	Understanding the impacts of landscape change on species distributions can help inform decision-making and conservation planning. Unfortunately, empirical data that span large spatial extents across multiple taxa are limited. In this study, we used expert elicitation techniques to develop species distribution models (SDMs) for harvested wildlife species (n = 10) in the New England region of the northeastern United States. We administered an online survey that elicited opinions from wildlife experts on the probability of species occurrence throughout the study region. We collected 3396 probability of occurrence estimates from 46 experts, and used linear mixed-effects methods and landcover variables at multiple spatial extents to develop SDMs. The models were in general agreement with the literature and provided effect sizes for variables that shape species occurrence. With the exception of gray fox, models performed well when validated against crowdsourced empirical data. We applied models to rasters (30 × 30 m cells) of the New England region to map each species’ distribution. Average regional occurrence probability was highest for coyote (0.92) and white-tailed deer (0.89) and lowest for gray fox (0.42) and moose (0.52). We then stacked distribution maps of each species to estimate and map focal species richness. Species richness (<i>s</i>) varied across New England, with highest average richness in the least developed states of Vermont (<i>s</i> = 7.47) and Maine (s = 7.32), and lowest average richness in the most developed states of Rhode Island (s = 6.13) and Massachusetts (s = 6.61). Our expert-based approach provided relatively inexpensive, comprehensive information that would have otherwise been difficult to obtain given the spatial extent and range of species being assessed. The results provide valuable information about the current distribution of wildlife species and offer a means of exploring how climate and land-use change may impact wildlife in the future.

Journal of Great Lakes Research. 46:1058-1062. \| Abstract	2020-07-31	Cisco (Coregonus artedi) and lake whitefish (Coregonus clupeaformis) are native fish species of management concern in the Laurentian Great Lakes that often overlap in spawning locations and timing. Thus, species-level inference from in situ sampling requires methods to differentiate their eggs. Genetic barcoding and rearing of live eggs to visually identify larvae are used but can be time and cost intensive. Observations in published literature indicate that in the Great Lakes, lake whitefish eggs may be larger than those of cisco, but this has not yet been substantiated. Samples from shared spawning grounds are unlikely to contain similarly sized or colored eggs from other species. Thus, we assessed whether their eggs could be separated based on size alone. Fertilized, hardened eggs were collected in situ during spawning at Elk Rapids, Lake Michigan and Chaumont Bay, Lake Ontario and preserved in ethanol. Individual eggs were measured and genetically identified. Mean diameter for cisco (2.45 mm, SD = 0.22, n = 444) was smaller than for lake whitefish (3.21 mm, SD = 0.20, n = 99). We used classification trees to identify a species-separating size threshold of 2.88 mm (95% bootstrap CI = [2.88, 2.95]), which classified eggs with an accuracy rate of 96%. Differences between species across other samples from the same locations were mostly consistent with the threshold size, but we suggest validation if applying this method to other populations. Separation of cisco and lake whitefish eggs by diameter can be accurate, efficient, and especially suitable for large sample sizes.

Fisheries Research 214:19-24. \| Abstract	2019-01-31	Successful reproduction in fish requires suitable conditions for spawning and egg incubation. Thus, fish species commonly exhibit spawning site selectivity, and understanding habitat requirements to inform population ecology and management relies on in situ observations of eggs. Numerous methods and devices have been developed to sample benthic, non-adhesive fish eggs to relate egg distribution, abundance, and survival to habitat characteristics, yet most do not have estimates of sampling efficiency despite assumptions of imperfect performance. We tested the efficiency of a gasoline-powered diaphragm pump with two different intake nozzle designs by sampling benthic, non-adhesive fish eggs at known densities (50, 200, and 500 eggs m-2) across a range of substrates: silt, gravel, and two depths of cobble. The sampler was ineffective on deep cobble substrate regardless of intake design. However, on substrates with less interstitial space, a narrower intake was consistently effective at detecting the presence of eggs (mean detection probability: 0.92) and demonstrated sufficient egg recovery to detect relative differences in abundance and to estimate absolute abundance with enough repeating samples. On average, 45% of eggs directly beneath the intake were recovered after four minutes of pumping, with most collected during the first two minutes. Eggs were often collected from outside the intake area, increasing variability in egg counts. When these limitations and imperfect efficiencies are accounted for, the pump sampler is uniquely suited for in situ assessment of eggs to inform large-scale spawning site use, small-scale habitat selection, and other applications relevant to spawning ecology.

While progeny sex ratios are typically stable at 1 : 1, sex reversal of genetic male catfish into functional females can be achieved with dietary steroid treatment. Morphological differentiation of ovaries and testes occur at 19 and 90–102 days post‐fertilization, respectively. The considerable time differential between ovarian and testicular differentiations suggests that testis‐inducing signals produced at ≥ 90 dpf are necessary for testicular differentiation in channel catfish –that is, the absence of estrogen production (necessary for ovarian differentiation) earlier in development is insufficient. Thus, testicular differentiation in channel catfish is proposed to occur in two phases: an early phase, when the sex‐determining gene downregulates the gonadal aromatase gene (cyp19a1a) and estrogen production to prevent ovarian differentiation; and a late phase, when masculinizing signals are produced and are required to initiate testicular formation. The products of gsdf and cxcl12 were recently identified for their potential role in the initiation of late‐phase testicular differentiation. All‐male progenies are desirable in channel catfish aquaculture because of their faster growth. A combination of feminizing steroid treatment, selective crossings, and progeny testing has been successfully used to produce YY male individuals that yield all‐male progenies when crossed with normal females. This procedure is time‐ and labor‐consuming, however, and has not been applied in commercial operations. The recent discovery of a male‐specific microsatellite marker may aid in the development of cost‐effective methods to produce YY brood stock.

Such information for management of tripletail (Lobotes surinamensis) is currently limited, particularly in the western Atlantic Ocean, as information regarding the reproductive biology of this species is sparse in the published literature. To this end, we determined the reproductive status of tripletail and compared results of a non-lethal sampling method, plasma vitellogenin (VTG) analysis, to traditional (lethal) methods: gonadosomatic index (GSI) and gonad histology. A total of 223 (122 males and 101 females) tripletail were sampled over two years near Jekyll Island, Georgia (USA). Gonad histology indicated 107 (94%) of the male tripletail were in the spawning-capable reproductive phase. Female tripletail were found in all reproductive phases, but only 9 (8.9%) were in the spawning-capable phase. Plasma VTG was strongly related to GSI in females (R2 = 0.832, n= 77) and female GSI differed significantly among reproductive phases (p <0.0001). The estimated length at which 50% (L50) of female tripletail reached maturity was 463 mm; however, the L50 for male tripletail could not be determined because of the lack of immature fish within the study sample. Our study provides valuable information for management of tripletail and indicates that a non-lethal approach (plasma VTG) may be useful for differentiating developing and spawning-capable females from males and from females in other reproductive phases.

Caribbean Naturalist 36:1-10. \| Abstract	2016-12-31	The shrub Solanum conocarpum Dunal (Solanaceae) is a small shrub endemic to coastal scrub and upland dry forests on the island of St. John, U.S. Virgin Islands, and is considered as a candidate plant species to be listed pursuant to the U.S. Endangered Species Act. Despite efforts to discover new populations by local conservationists and biologists from Virgin Islands National Park, U.S. National Park Service, only eight populations have been documented to date. Of these, six populations occur within the boundaries of Virgin Islands National Park (VINP), one of which is located on the periphery of the park. Information is needed to prioritize locations for future surveys, determine possible reintroduction sites and assess potential habitat in private lands. Therefore, we incorporated environmental characteristics (vegetation cover, soil associations, elevation, and VINP boundaries) found at three of the known populations (Nanny Point, John’s Folly, and Brown’s Bay Trail) into a Geographical Information System (GIS) model to create a habitat suitability map for the island of St. John. A total of 1159.38 hectares of highly suitable and moderately suitable habitat was found on the island of St. John. Of these, 714.96 hectares (61.66 %) are found within the boundaries of VINP. However, areas of suitable habitat were found on private lands, namely the East End peninsula and lower elevation scrub forest on Johns Folly Bay and Sabbat Point. Given the high development pressure on private lands at lower elevations in the U.S. Virgin Islands, the presence of invasive browsers on the island, and potential seed predation by native hermit crabs (Coenobita clypeatus), the habitat suitability model provides important information on potential locations for future surveys and restoration sites to assist recovery actions for the species.

International Journal of Biometeorology 63:1059-1067. https://doi.org/10.1007/s00484-019-01720-2 \| Abstract	2019-08-31	Male wild turkeys’ (Meleagris gallopavo) breeding behavior consists of vocalizations and courtship displays to attract females; the phenology of which can vary with latitude and climate. Wildlife biologists frame spring wild turkey hunting seasons around annual trends in vocalization peaks to maximize hunter engagement. Historically, the Mississippi Department of Wildlife, Fisheries, and Parks institutes a statewide 7 week spring harvest season; however, hunters routinely suggested there were different peaks in gobbling activity across a latitudinal gradient within the state. Our objectives were to determine if there were differences in peak gobbling activity between southern and northern Mississippi, if the current spring harvest seasons captured the peaks in gobbling activity, and to describe potential weather conditions that were observed during gobbling activity. During 2008 and 2009, we constructed a statewide gobbling survey to monitor gobbling activity and queried four Spatial Synoptic Classification sites to compare concurrent weather conditions. We determined an approximate 2 week difference in peak gobbling activity between southern and northern Mississippi. Further, the majority of all gobbling activity occurred within the spring harvest framework. We also observed gobbling activity was more prevalent on days of regionally dry conditions according to Spatial Synoptic Classification. Our results provide information to managers about the phenology of gobbling activity relative to season dates and useful weather-response information that may be of interest to hunters. Our approach could be modeled elsewhere and provide beneficial information particularly in states with relatively shorter seasons.

Each of these principles has been employed for restoring and managing wild turkeys (Meleagris gallopavo). Today, we enjoy abundant populations and hunting opportunities, but potential threats could erode these in the future. These include trends towards commercialization and privatization, reduced land access for hunting, erosion of science, public antipathy towards hunting, and reduction of forest habitat quality due to limitations on forest management practices. Herein, I discuss each of these elements and challenges of maintaining relevance of the North American Model to wild turkey management.

(in press) Outmigration survival of wild Chinook salmon smolts through the Sacramento River during historic drought and high water conditions. environmental biology of fishes. \| Abstract	2020-05-31	Populations of wild spring-run Chinook salmon (Oncorhynchus tshawytscha) in California’s Central Valley, once numbering in the millions, have dramatically declined to record low numbers in recent years. Dam construction, habitat degradation, and altered flow regimes have all contributed to depress populations of spring-run salmon, which currently persist in only a few tributaries to the Sacramento River. Mill Creek (Tehama County) continues to support these threatened fish, and contains some of the most pristine spawning and rearing habitat available in the Central Valley. Despite this pristine habitat, the number of spring-run salmon returning to spawn has declined to record low numbers, and is likely attributed to poor outmigration survival rates. Using miniature acoustic tags, it is now possible to track out-migrating juveniles throughout the freshwater migration corridor. From 2013-2017 we captured and acoustic tagged 334 smolts out-migrating from Mill Creek, tracking their movement and survival rates over 250 kilometers through the Sacramento River. During this study California experienced both an unprecedented drought and record rainfall, resulting in dramatic fluctuations in year-to-year river flows and water temperature. Cumulative survival of tagged smolts from Mill Creek through the Sacramento River was 9.5% (±1.6) during the study, with relatively low survival during historic drought conditions in 2015 (4.9% ± 1.6) followed by increased survival during high flows in 2017 (42.3% ± 9.1). From these data, we modeled survival in Mill Creek and the Sacramento River over a range of flow values, which indicated that higher flows in each region result in increased survival rates. Data gathered in this study can help focus management and restoration actions over a relatively long migration corridor to specific regions of low survival, and provide guidance for management actions in the Sacramento River aimed at restoring populations of threatened Central Valley spring-run Chinook salmon.

North American Journal of Fisheries Management 40:394-3405. doi.org/10.1002/nafm.10419 \| Abstract	2020-04-30	Winter drawdowns in flood control reservoirs create expansive mudflats that lack the vegetation typical of littoral zones, which reduces the amount of structure available for fish habitat. This study investigated the feasibility of establishing agricultural plantings as a management action to ameliorate mudflats by providing structural cover following reservoir refilling. We tested cool‐season annual grasses and clovers applied in several mixed and monoculture treatments that were sown on the mudflats of Enid Reservoir, Mississippi, during the winter drawdown in three consecutive years. Soil samples were taken for analysis of pH and macronutrients prior to planting. Plantings were monitored until the following spring to evaluate effectiveness of establishment through ground coverage, height, and stem density sampling. Plots were assigned a seeding treatment of either grasses (ryegrass <i>Lolium</i> spp. or triticale <i>x Triticosecale</i> sp.), clovers (balansa clover <i>Trifolium michelianum</i> or berseem clover <i>Trifolium alexandrinum</i>), or both (mixed plantings) or left as an unseeded control. Differences among plant treatments were assessed via repeated measures analysis of variance and differences among means evaluated with Tukey's honestly significant difference test. Soil productivity within the study area was poor all 3 years. Grasses germinated both when disked into the soil and when top sown, while clover only germinated when disked. Plots seeded with grasses performed better than control plots with respect to stem density, height, and ground coverage, while plots seeded with grass and clover mixtures performed better than control plots only with respect to height, and plots seeded with only clover did not perform significantly better than control plots. Results serve as an evaluation of the efficacy of agricultural plant establishment on the mudflats of a flood control reservoir, inform the direction of future research, and identify considerations regarding the application of agricultural plantings as a management tool to create fish habitat.

EcoHealth, pp.1-11. \| Abstract	2016-01-31	Monitoring is best viewed as a component of some larger programme focused on science or conservation. The value of monitoring is determined by the extent to which it informs the parent process. Animal translocation programmes are typically designed to augment or establish viable animal populations without changing the local community in any detrimental way. Such programmes seek to minimize disease risk to local wild animals and to translocated animals. Disease monitoring can inform translocation decisions by (1) providing information for state-dependent decisions, (2) assessing progress towards programme objectives, (3) permitting learning in order to make better decisions in the future, and (4) providing parameter estimates for process models. Here we discuss specific decisions that can be informed by both pre-release and post-release disease monitoring programmes. We specify state variables and vital rates needed to inform these decisions. We then discuss monitoring data and analytic methods that can be used to estimate these state variables and vital rates. Our discussion is necessarily general, but hopefully provides a basis for tailoring disease monitoring approaches to specific translocation programmes.

Wildlife Society Bulletin 40:705-713. \| Abstract \| Download	2016-12-31	The last comprehensive nest survival study of the breeding giant Canada goose (Branta canadensis maxima) population in Iowa, USA, was conducted >30 years ago during a period of population recovery, during which available nesting habitat consisted primarily of artificial nest structures. Currently, Iowa’s resident goose population is stable and nests in a variety of habitats. We analyzed the effects of available habitat on nest survival and how nest survival rates compared with those of the expanding goose population studied previously to better understand how tomaintain a sustainable Canada goose population in Iowa. We documented Canada goose nest survival at rural wetland sites in north-central Iowa. We monitored 121 nests in 2013 and 149 nests in 2014 at 5 Wildlife Management Areas (WMAs) with various nesting habitats, including islands, muskrat (Ondatra zibethicus) houses, and elevated nest structures. We estimated daily nest-survival rate using the nest survival model in Program MARK. Survival was influenced by year, site, stage, presence of a camera, nest age, and an interaction between nest age and stage. Nest success rates for the 28-day incubation period by site and year combination ranged from 0.10 to 0.84. Nest survival was greatest at sites with nest structures (b¼17.34). Nest survival was negatively affected by lowered water levels at Rice Lake WMA (2013 b¼0.77, nest age b¼0.07). Timing of water-level drawdowns for shallow lake restorations may influence nest survival rates.

DOI: 10.1111/1365-2656.12810 \| Abstract	2018-03-31	Prey abundance and prey vulnerability vary across space and time, but we know little about how they mediate predator-prey interactions and predator foraging tactics. To evaluate the interplay between prey abundance, prey vulnerability, and predator space use, we examined patterns of black bear (Ursus americanus) predation of caribou (Rangifer tarandus) neonates in Newfoundland, Canada using data from 317 collared individuals (9 bears, 34 adult female caribou, 274 caribou calves). During the caribou calving season, we predicted that landscape features would influence calf vulnerability to bear predation, and that bears would actively hunt calves by selecting areas associated with increased calf vulnerability. Further, we hypothesized that bears would dynamically adjust their foraging tactics in response to spatiotemporal changes in calf abundance and vulnerability (collectively, calf availability). Accordingly, we expected bears to actively hunt calves when they were most abundant and vulnerable, but switch to foraging on other resources as calf availability declined. As predicted, landscape heterogeneity influenced risk of mortality, and bears displayed the strongest selection for areas where they were most likely to kill calves, which suggested they were actively hunting caribou. Initially, the per-capita rate at which bears killed calves followed a type-I functional response, but as the calving season progressed and calf vulnerability declined, kill rates dissociated from calf abundance. In support of our hypothesis, bears adjusted their foraging tactics when they were less efficient at catching calves, highlighting the influence that predation phenology may have on predator space use. Contrary to our expectations, however, bears appeared to continue to hunt caribou as calf availability declined, but switched from a tactic of selecting areas of increased calf vulnerability to a tactic that maximized encounter rates with calves. Our results reveal that generalist predators can dynamically adjust their foraging tactics over short time scales in response to changing prey abundance and vulnerability. Further, they demonstrate the utility of integrating temporal dynamics of prey availability into investigations of predator-prey interactions, and move towards a mechanistic understanding of the dynamic foraging tactics of a large omnivore.

Oecologia DOI 10.1007/s00442-017-3971-8 \| Abstract	2017-10-31	Anthropogenic disturbances have altered species’ distributions potentially impacting interspecific interactions. Interference competition is when one species denies a competing species access to a resource. One mechanism of interference competition is aggression, which can result in altered space-use of a subordinate species due to the threat of harm, otherwise known as a ‘landscape of fear’. Alternatively, subordinates might outcompete dominant species in resource-poor environments via a superior ability to extract resources. Our goal was to evaluate spatial predictions of the ‘landscape of fear’ hypothesis for a carnivore guild in Newfoundland, Canada, where coyotes recently immigrated. Native Newfoundland carnivores include red foxes, Canada lynx, and black bears. We predicted foxes and lynx would avoid coyotes because of their larger size and similar dietary niches. We used scat-detecting dogs and genetic techniques to locate and identify predator scats. We then built resource selection functions and tested for avoidance by incorporating predicted values of selection for the alternative species into the best supported models of each species. We found multiple negative relationships, but notably did not find avoidance by foxes of areas selected by coyotes. While we did find that lynx avoided coyotes, we also found a reciprocal relationship. The observed patterns suggest spatial partitioning and not coyote avoidance, although avoidance could still be occurring at different spatial or temporal scales. Furthermore, Newfoundland’s harsh climate and poor soils may swing the pendulum of interspecific interactions from interference competition to exploitative competition, where subordinates outcompete dominant competitors through a superior ability to extract resources.

Journal of Fish and Wildlife Management 8:79-88. \| Abstract	2017-06-30	Decreases in the abundance and diversity of stream fishes in the North American Great Plains have been attributed to habitat fragmentation, altered hydrological and temperature regimes, and elevated levels of total dissolved solids and total suspended solids. Pelagic-broadcast spawning cyprinids, such as the Arkansas River Shiner Notropis girardi, may be particularly vulnerable to these changing conditions due to their reproductive strategy. Our objectives were to assess the effects of temperature, total dissolved solids, and total suspended solids on the developmental and survival rates of Arkansas River Shiner larvae. Results suggest temperature had the greatest influence on the developmental rate of Arkansas River Shiner larvae. However, embryos exposed to the higher levels of total dissolved solids and total suspended solids reached developmental stages earlier than counterparts at equivalent temperatures. Although this rapid development may be beneficial in fragmented waters, our data suggest it may be associated with lower survival rates. Furthermore, those embryos incubating at high temperatures, or in high levels of total dissolved solids and total suspended solids resulted in less viable embryos and larvae than those incubating in all other temperature, total dissolved solid, and total suspended solid treatment groups. As the Great Plains ecoregion continues to change, these results may assist in understanding reasons for past extirpations and future extirpation threats as well as predict stream reaches capable of sustaining Arkansas River Shiners and other species with similar early life-history strategies.

ICES Journal of Marine Science 77:539-552. \| Abstract	2020-03-31	Ecosystem-scale examination of fish communities typically involves creating spatio-temporally explicit relative abundance distribution maps using data from multiple fishery-independent surveys. However, sampling performance varies by vessel and sampling gear, which may influence estimated species distribution patterns. Using GAMMs, the effect of different gear–vessel combinations on relative abundance estimates at length was investigated using European fisheries-independent groundfish survey data. We constructed a modelling framework for evaluating relative efficiency of multiple gear–vessel combinations. 19 northeast Atlantic surveys for 254 species-length combinations were examined. Space-time variables explained most of the variation in catches for 181/254 species-length cases, indicating that for many species, models successfully characterized distribution patterns when combining data from disparate surveys. Variables controlling for gear efficiency explained substantial variation in catches for 127/254 species-length data sets. Models that fail to control for gear efficiencies across surveys can mask changes in the spatial distribution of species. Estimated relative differences in catch efficiencies grouped strongly by gear type, but did not exhibit a clear pattern across species’ functional forms, suggesting difficulty in predicting the potential impact of gear efficiency differences when combining survey data to assess species’ distributions and highlighting the importance of modelling approaches that can control for gear differences.

Journal of Wildlife Management 83:1617–1627. DOI:10.1002/jwmg.21741. \| Abstract	2019-08-31	As with many migratory birds, migratory connectivity of American woodcock (Scolopax minor; hereafter, woodcock) is largely unknown. Understanding migratory connectivity and migration phenology is important in identifying factors that influence survival and fitness over the full annual cycle. However, until recently, practical methods (i.e., data derived from banding and VHF telemetry) for elucidating migratory connectivity and migration phenology of woodcock have provided relatively coarse-resolution delineation of migration patterns. Based largely on analysis of band returns, woodcock are managed in 2 management regions (Eastern and Central Management Regions) with management region boundaries analogous to those of the Atlantic and Mississippi Flyways. To better understand woodcock migration and evaluate the validity of current management regions, we deployed satellite transmitters on 73 woodcock in the Central Management Region, and from 2014-2016 documented migration paths of 60 individual woodcock and 87 autumn or spring woodcock migrations. Marked woodcock captured in the Central Management Region used 2 primary migrations routes: a Western Route and a Central Route. The Western Route ran north-south, connecting the breeding and wintering grounds within the Central Management Region. The hourglass-shaped Central Route connected an area on the wintering grounds reaching from Texas to Florida, to sites throughout northeastern North America in the Eastern Management Region and Central Management Region. Woodcock following the Central Route migrated through the area between the Appalachian Mountains and the Mississippi Alluvial Valley in western Tennessee during both autumn and spring. A higher than anticipated (based on previous banding data analyses) percentage (36%, n = 12) of marked woodcock captured in Texas and Louisiana and monitored during spring migration migrated to breeding-period sites in the Eastern Management Region, raising questions about the biological relevance of managing woodcock in separate management regions.
Moore, J. D., and D. G. Krementz. 2017. Migratory connectivity of American woodcock using band return data. Journal of Wildlife Management. 81: \| Abstract	2017-04-30	American woodcock (Scolopax minor) are managed as a Central and an Eastern population. Band return data showing little crossover between populations or management regions has been used as biological justification for these Central and Eastern Management Regions. However, the observed proportion of crossover between management regions depends on the criteria used to subset the band return dataset. We analyzed the amount of crossover between management regions using only band return records that represent complete migrations between the breeding and wintering grounds by using only band return records in which the capture took place during the breeding season and the encounter took place during the wintering season or vice versa (n = 224). Additionally, we applied spatial statistics and a clustering algorithm to investigate woodcock migratory connectivity using this subset of migratory woodcock band return records. Using raw counts, 17.9% of records showed crossover between management regions, a higher proportion than the <5% crossover found in studies that did not use only migratory band returns. Our results showed woodcock from the breeding grounds in the Central Region largely migrate to destinations within the Central Region, whereas woodcock from the breeding grounds in the Eastern Region migrate to destinations across the entire wintering range and mix with individuals from the Central Region. Using the division coefficient, we estimated that 54% of woodcock from the breeding grounds of the Eastern Region migrate to the Central Region. Our result that many woodcock from separate regions of the breeding grounds mix on the wintering grounds has implications for the present two-region basis for woodcock management. Elucidating finer scale movement patterns among regions provides a basis for reassessing the boundaries to ensure optimal conservation and management of the species.

Proceedings of the 11th American Woodcock Symposium, University of Minnesota Libraries Publishing, Minneapolis, Minnesota, U.S.A. DOI:10.24926/AWS.0124. \| Abstract \| Download	2019-12-31	The American woodcock (Scolopax minor) Singing-Ground Survey (SGS) was developed to inform management decisions by monitoring changes in the relative abundance of woodcock. The timing of the designated survey windows were designed to count woodcock that have settled in an area while minimizing the counting of migrating woodcock to the best extent possible. Since the implementation of the SGS in 1968, concerns over survey protocols that may bias data have been raised and investigated; however, the extent of survey coverage , the timing of the survey window zones, and whether double counting might occur within and among survey zones have not been critically investigated We used three years of data collected from satellite-marked male and female woodcock to assess the timing of the SGS survey windows and to what extent there was potential to double count woodcock among the survey zones. SGS coverage encompassed the majority of woodcock breeding-period sites within the U.S. (n = 17, 92%) and approximately half of the breeding period sites in Canada (n = 6, 43%). Thirteen of the 37 monitored woodcock with known breeding-period site arrival dates (35%) were migrating through a survey zone during an active survey window, all in the northernmost four out of five SGS zones. Thirteen woodcock arrived at breeding period sites after the start of surveys, all but one with breeding-period sites in the northernmost two zones. The combination of these situations may result in the SGS weighing too heavily the contribution of routes in southern portion of the primary breeding range while weighing too lightly the routes in the northern portion of the primary breeding range. We believe that we have demonstrated enough concerns about zone window timing to suggest that additional information is necessary to evaluate whether current zone window dates are sufficient, or whether they need to be changed.

Toxicity of Potassium Chloride to Veliger and Byssal-Stage Dreissenid Mussels Related to Water Quality.Management of Biological Invasions 7: 257–268. \| Abstract \| Download	2016-07-31	Natural resource managers are seeking appropriate chemical eradication and control protocols for infestations of dreissenid mussels, Dreissena polymorpha, D. rostiformis bugensis, that have limited effect on non-target species. Applications of low concentrations of potassium salt (as potash) have shown promise for use where the infestation and treatment can be contained or isolated. To further our understanding of such applications and obtain data that could support a pesticide registration, we conducted studies of the acute and chronic toxicity of potassium chloride to dreissenid mussels in four different sources of water sources from infested and non-infested locations (ground water from northern Idaho, surface water from the Snake River, ID, surface water from Lake Ontario, Ontario, Canada, and surface water from the Colorado River, AZ). We found short term exposure of veligers (< 24 h) to concentrations of 960 mg/L KCl produced rapid mortality in water from three locations, but veligers tested in Colorado River water were resistant. We used probit models to compare the mortality responses, predicted median lethal times and 95% confidence intervals. In separate tests, we explored the sensitivity of byssal stage mussels in chronic exposures (>29 d) at concentrations of 100 and 200 mg/L KCl. Significant and rapid mortality occurred within 10 d of exposure to concentrations of 200 mg/L KCl, regardless of water source. Mean survival of byssal mussels in 100 mg/L KCl prepared in surface water from Idaho and Lake Ontario was 4.9 or 6.9 d, respectively; however mean survival of mussels tested in the Colorado River water was > 22 d. We found the sodium content of the Colorado River water was nearly three times the concentration measured in waters from the other locations, and hypothesized that sodium concentrations may affect mussel survival. Additional trials tested mussel survival in surface water sources after supplementing water with NaCl to equivalent conductivity with the Colorado River water. Addition of NaCl was significantly effective in slowing the mortality responses to concentrations of KCl. The survival was similar to that for veliger and byssal stage mussels in Colorado River water. We recommend that any additional studies and protocols for disinfection and eradication with KCl carefully consider the water quality characteristics of treatment.

U.S. Department of Interior, Fish and Wildlife Service, Cooperator Science Series XXX-XXX. Washington, D.C. \| Abstract	2019-06-30	Blue Sucker (Cycleptus elongatus) is a state-listed threatened species in Texas and is considered vulnerable throughout its range. Once considered a single, wide-ranging species, blue suckers are now recognized as a complex of closely related, but genetically and morphologically distinct species within the genus Cycleptus, including an undescribed species within the Rio Grande Basin. Numerous factors likely are driving the decline of blue suckers in Texas, including flow alteration, water quality, habitat fragmentation, and changing land-use patterns, but it is not clear how these factors interact to influence the abundance and distribution of the species. Our research integrates a variety of methodologies to provide information critical to the conservation and management of Blue Sucker in the Sabine River (Texas and Louisiana) and Colorado River (Texas) and Rio Grande Blue Sucker (Cycleptus sp. cf. elongatus) in the Rio Grande. The objectives of this report are to 1) determine the habitat associations of the young-of-the-year (YOY) Rio Grande Blue Sucker; 2) assess the effects of flow regime on growth and recruitment of Blue Sucker in the lower Sabine River; and 3) examine differences in life-history traits of Blue Suckers and flow regime across river basins in Texas. This study is the first to quantitatively address the sequence of YOY blue sucker mesohabitat use and increases our understanding of early life history of blue suckers, and the results of this work will help to develop conservation and management strategies (e.g., prioritizing conservation areas, developing flow recommendation, etc.) for blue suckers throughout their geographic distribution. Key findings of this study were: 1) The body size of YOY Rio Grande Blue Sucker in pool habitats were significantly lower than that in other mesohabitats, suggesting that YOY Rio Grande Blue Sucker undergo onotogenetic habitat shifts into higher current velocity habitats as they grow. 2) Slow current areas, such as pools, could be important nursery habitats for small YOY Rio Grande Blue Sucker (total length ≤ 45 mm). 3) YOY Rio Grande Blue Sucker move into riffles and runs as they grow from April to June, suggesting that extreme low flow conditions during early summer may negatively affect the habitat quality or availability for YOY Rio Grande Blue Sucker. 4) The growth and recruitment of Blue Sucker in the lower Sabine River increased with increasing the river discharge from early summer to fall in our study areas. 5) The life-history traits of Blue Sucker differed between the lower Sabine River and the lower Colorado River: the total length and age of Blue Sucker in the lower Colorado River were larger than those of Blue Sucker in the lower Sabine River, and the growth and mortality rates of Blue Sucker of the lower Sabine River tended to be higher than those of the lower Colorado River. 6) Our results suggest that mesohabitat area and flow regime could be important factors determining the growth and recruitment of blue suckers, and the importance of these environmental factors could change according to the life-history stage (larval stage, juvenile stage, and adult stage). 7) Important areas for future research efforts include a) quantifying the differences in the mesohabitat area/quality/density among the three river basins; b) examining interactions between the spatial distributions of potential spawning habitat relative to suitable YOY mesohabitat and how variations in river flow influence their quality and connectivity to each other; and c) continuing to monitor the effects of flow regime on blue suckers for longer time periods.

In view of this deficit, our objective was to assess diel water quality patterns in the nearshore zone of a reservoir and test whether diel patterns differed relative to the presence or absence of riparian shade. Light intensity, temperature, dissolved oxygen, turbidity, oxidation-reduction potential, and specific conductance were greater in unshaded sites (p < 0.05), whereas concentrations of phosphate and nitrate were greater in shaded sites, and pH values were similar in shaded and unshaded sites. Most variables exhibited distinct diel cycles, except specific conductance, turbidity, phosphate, and nitrate. Other than light intensity (average 66% lower in shade), differences in water quality patterns between shaded and unshaded sites seemed small (average <5%) and within the range of tolerances of aquatic biotic communities. In most lacustrine systems the nearshore shaded band is small relative to the unshaded open water, and the large open-water volume tends to neutralize effects of shading on water physicochemistry. As a result, riparian shade may not have a large influence on water temperature and chemistry of lacustrine systems, and its biggest effect may be a reduction in light intensity in the nearshore band. The observed decrease in light intensity in shaded sites has the potential to influence biotic assemblages through competitive mechanisms associated with finding food, avoiding predation, and other aspects associated with rather than through physiologic effects via water quality.

The effects of climate change are increasingly evident and are anticipated to profoundly affect our ability to conserve fish habitats and fish assemblages as we know them. Preparing to cope with the effects of climate change is developing as the central concern of aquatic resources conservation and management. Reservoirs are important structures for coping with projected shifts in water supply, but they also provide refuge for riverine fishes and retain distinct fish assemblages that support diverse fisheries. The effects of climate change on reservoirs are unique among aquatic systems because reservoirs have distinctive habitat characteristics due to their terrestrial origin and strong linkage to catchments. We review (1) the projected effects of rising temperature and shifting precipitation on reservoir fish habitats, and (2) adaptation strategies to cope with the anticipated effects. Climate warming impacts to reservoirs include higher water temperatures and shifts in hydrology that can result in reduced water levels in summer and fall, altered water residence cycles, disconnection from upstream riverine habitats and backwaters, increased stratification, eutrophication, anoxia, and a general shift in biotic assemblages including plants, invertebrates, and fishes. We suggest that what is needed to cope with these changes is a perspective that focuses on maintaining ecosystem functionality rather than on retaining a certain species composition. To that end, we identify various strategies organized into planning, monitoring, and managing compartments. The coping strategies we identify are broad and general and represent a starting line applicable for developing creative alternatives relevant to local conditions.

A basin-scale perspective may increase awareness at a broader scope and generate insight not evident at local scales. We examined the diversity of reservoir attributes and fisheries in the Mississippi Basin to identify management opportunities. The basin is the third largest in the world and includes over 1,700 reservoirs >100 ha, the most of any river basin anywhere. Our bird’s-eye view reveals a piecemeal approach where reservoirs are mostly administered at the local level. Basin-wide or catchment coordination to holistically address problems that recur across the basin is mostly lacking. A basin-wide coordination arrangement akin to the North American Waterfowl Management Plan could facilitate various facets of reservoir management. Such an arrangement may steer reservoir fisheries management through a potentially turbulent 21st century as reservoirs age beyond their useful life and climate shifts render status-quo management ineffective.

Single nucleotide polymorphisms within the prion gene have been linked to differential susceptibil-ity to the disease in many species. Wildlife managers are seeking to determine the frequencies of disease-associated alleles and genotypes and delineate spatial genetic patterns. The CWDPRNP package, implemented in program R, provides a unified framework for analyzing prion gene varia-bility and spatial structure.

Prion 13: 65-76. \| Abstract	2019-02-28	Genetic variability in the prion protein (PRNP) gene influences host susceptibility to many pathogenic prion diseases. Understanding the distribution of susceptible PRNP variants and determining factors influencing spatial genetic patterns are important components of many chronic wasting disease mitigation strategies. Here, we describe PRNP variability in white-tailed deer (Odocoileus virginianus) from the Mid-Atlantic region of the United States of America, an area with a recent history of infection and low disease incidence. This population is characterized by lower rates of polymorphism and significantly higher frequencies of the more susceptible 96GG genotype compared to previously surveyed populations. The prevalence of the most susceptible genotypes at disease-associated loci did vary among subregions, indicating that populations have innate differences in genotype-dictated susceptibility.

Ocean and Coastal Management 126:42-50. DOI: https://doi.org/10.1016/j.ocecoaman.2016.03.014 \| Abstract	2016-06-30	Most ecosystems are subject to both natural and human disturbances that can combine to influence populations and assemblages in complex ways. Assessing the relative influences and combined impacts of natural and human disturbance is crucial for managing human uses of ecosystems against the backdrop of their natural variability.We evaluated the separate and combined influences of disturbance from storm waves and disturbance associated with human trampling of rocky shores by conducting an experiment mimicking controlled levels of trampling at sites with different wave exposures, and before and after a major storm event in central California, USA. Results show that trampling and storm waves affected the same taxa and have comparable and additive effects on rocky shore assemblages. Both disturbance types caused significant reduction in percent cover of mussels and erect macroalgae, and resulted in significant re-organization of assemblages associated with these habitat-forming taxa. A single extreme storm event caused similar percent cover losses of mussels and erect macroalgae as did 6 e12 months of trampling. Contrary to a predicted synergistic effect of trampling and storm damage, we found that impacts from each disturbance combined additively. Mussel beds in wave-exposed sites are more vulnerable to trampling impacts than algal beds at protected sites. Mussels and erect macroalgae recovered within five years after trampling stopped. These results suggest that impacts from local human use can be reversed in relatively short time frames, and that cumulative impacts can be reduced by setting recreational carrying capacities more conservatively when ecosystems are already exposed to frequent and/or intense natural disturbances.
Michel, E.S., J.A. Jenks, K.D. Kaskie,, R.W. Klaver, and W. F. Jensen. 2018. Weather and landscape factors affect white-tailed deer neonates at ecologically important life stages in the Northern Great Plains.. PLoS ONE 13:e0195247 \| Abstract \| Download	2018-04-30	Offspring survival is generally more variable than adult survival and may limit population growth. Although white-tailed deer neonate survival has been intensively investigated, recent work has emphasized how specific cover types influence neonate survival at local scales (single study area). These localized investigations have often led to inconsistences within the literature. Developing specific hypotheses describing the relationships among environmental, habitat, and landscape factors influencing white-tailed deer neonate survival at regional scales may allow for detection of generalized patterns. Therefore, we developed 11 hypotheses representing the various effects of environmental (e.g., winter and spring weather), habitat (e.g., hiding and escape cover types), and landscape factors (e.g., landscape configuration regardless of specific cover type available) on white-tailed deer neonate survival up to one-month and from one- to three-months of age. At one-month, surviving fawns experienced a warmer lowest recorded June temperature and more June precipitation than those that perished. At three-months, patch connectance (percent of patches of the corresponding patch type that are connected within a predefined distance) positively influenced survival. Our results are consistent with white-tailed deer neonate ecology: increased spring temperature and precipitation are likely associated with a flush of nutritional resources available to the mother, promoting increased lactation efficiency and neonate growth early in life. In contrast, reduced spring temperature with increased precipitation place neonates at risk to hypothermia. Increased patch connectance likely reflects increased escape cover available within a neonate's home range after they are able to flee from predators. If suitable escape cover is available on the landscape, then managers could focus efforts towards manipulating landscape configuration (patch connectance) to promote increased neonate survival while monitoring spring weather to assess potential influences on current year survival.

Submitted to Ecological Applications. \| Abstract	2020-06-30	Spatial patterns and environmental predictors of predator-prey dynamics are often investigated at discrete locations, limiting our ability to extrapolate to broader landscape scales. At these broader scales, landscapes often contain multiple complex and heterogeneous habitats, thus a spatially balanced sample throughout the different habitats is necessary to sufficiently represent them. This challenge is especially pronounced in California’s Sacramento-San Joaquin River Delta, where the landscape scale impact of fish predators on native prey fish is information needed by managers to protect multiple imperiled populations. During the spring of 2017, we quantified relative predation risk in the southern half of the Delta (South Delta) using floating baited tethers that record the exact time and location of predation events. We selected 20 study sites (1-km long) using a generalized random tessellation stratified survey design, which allowed us to infer relationships between the environment and predation across a broader spatial scale compared to previous studies. In addition to estimating relative predation risk at each study site, we also collected relevant environmental covariates including distance to nearest predators, water temperature, turbidity, depth, bottom slope, bottom roughness, water velocity, and distance to nearest riverbank and nearest submerged aquatic vegetation. We employed model selection to determine the environmental covariates that best predicted predation risk. Our most parsimonious model included water temperature, time of day, mean predator distance, and river bottom roughness. Using this model, we estimated predation risk for the entire South Delta at a 1-km resolution. This effort identified certain predation risk hotspots - the most important of which was corroborated by other studies - and allowed us to generate predicted survival rates for migrating fish transiting the South Delta. Because the 2017 water year was unusually wet, this methodology should be repeated across a suite of hydrologically distinct years to further develop the relationships.

DOI 10.1007/s10530-016-1322-z. USGS IP-069503 \| Abstract	2016-11-30	Trout species often segregate along elevational gradients, yet the mechanisms driving this pattern are not fully understood. On the Logan River, Utah, USA, exotic brown trout (Salmo trutta) dominate at low elevations but are near-absent from high elevations with native Bonneville cutthroat trout (Onchorhynchus clarkii utah). We used a Bayesian, spatial modeling approach to evaluate abiotic conditions (describing mechanisms related to temperature and physical habitat) potentially influencing the distribution of brown trout in this system. We also considered the influence of propagule pressure, including the intensity of past stocking pressure and distance from a concentrated stocking area. The distribution of brown trout was best explained by models describing: 1) average summer temperature interacting with unit stream power, our measure of gravel availability for spawning (R2=0.54), and 2) the prevalence of anchor ice between each reach and a high-intensity stocking area, also interacting with our measure of gravel availability (R2=0.52). Based on these findings, effects of cold summer temperatures on age-0 survival and/or the lack of movement upstream due to anchor ice are likely mechanisms contributing to low abundance of brown trout at high elevations. The potential role of anchor ice in affecting longitudinal distributions of brown trout has not been well-explored in other research. These findings have implications for future brown trout expansion upstream given some evidence suggesting anchor ice prevalence on the Logan River has decreased significantly over the last several decades, likely in response to climatic changes.

Submitted to River Research and Applications, 28 December, 2017. USGS FSP: \| Abstract	2018-01-31	In the Intermountain West, USA, eggs and fry of fall-spawning brown trout are susceptible to scour-related mortality because they are still in the gravel during spring snowmelt run-off events. The goal of our research was to understand patterns of gravel scour on the Logan River, Utah in relation to brown trout spawning preferences and whether mobility of spawning gravels could explain the absence of brown trout from higher elevations. We collected data to characterize local and reach-scale potential for spawning gravel scour (i.e., “entrainment potential”) at representative reaches along a longitudinal gradient during 2009 and 2010 spring flood events. We also used scour chains to measure scour depth at spawning locations. The flood magnitude in both years approximated the 2-year flood magnitude, but the flood in 2009 was much longer in duration. Scour at 27% of scour chain locations exceeded our estimated median depth of developing fry in 2009, while scour at 0% of locations exceeded this depth in 2010. Fewer low-gradient reaches were present in the upstream, non-canyon sections. However, across all reaches, we found that brown trout preferentially chose locations in channel margins for spawning, which tended to have low entrainment potential. These local estimates of entrainment potential predicted scour depth better than reach-scale estimates or broad-scale patterns of geomorphology. Some of the greatest scour depths were measured in the backwaters of a dam, a location with low entrainment potential but potentially greater sediment supply. Our findings suggest that spawning gravel scour is not limiting brown trout abundance at high elevations in this system given shallow scour depths overall and selection of low-scour areas for spawning.

(2016). Molecular Ecology Resources. \| Abstract	2016-12-31	In their recently corrected manuscript, “Breaking RAD: An evaluation of the utility of restriction site associated DNA sequencing for genome scans of adaptation”, Lowry et al. argue that genome scans using RADseq will miss many loci under selection due to a combination of sparse marker density and low levels of linkage disequilibrium inmost species. We agree that marker density and levels of LD are important considerations when designing a RADseq study; however, we dispute that RAD-based genome scans are as prone to failure as Lowry et al. suggest. Their arguments ignore the ﬂexible nature of RADseq; the availability of different restriction enzymes and capacity for combining restriction enzymes ensures that a well-designed study should be able to generate enough markers for efﬁcient genome coverage. We further believe that simplifying assumptions about linkage disequilibrium in their simulations are invalid in many species. Finally, it is important to note that the alternative methods proposed by Lowryet al. have limitations equal to or greater than RADseq. The wealth of studies with positive impactful ﬁndings that have used RAD genome scans instead supports the argument that properly conducted RAD genome scans are an effective method for gaining insight into ecology and evolution, particularly for non-model organisms and those with large or complex genomes.

Restoration Ecology. doi: 10.1111/rec.12498 \| Abstract	2017-01-31	Oyster reef restoration in coastal systems has recently received increased funding with an implicit desire to enhance oyster density and the ecosystem services they provide. Although oyster restoration has been proven a successful strategy to increase density and biomass of the associated transient fish, predicting and quantifying the effect of oyster restoration on transient fish communities remains a challenge. A bioenergetics model was developed to assess the impact of selected oyster reef restoration scenarios on associated transient fish species. The model was used to analyze the impact of changes in (1) oyster carrying capacity (2) oyster growth rate and (3) diet preference of transient fish on oyster reef development and associated transient fish species. Model results were within expected values and corroborate results from previous field and mesocosm studies. The model highlights the importance of a favorable oyster growth rate during early restoration years, as it can lead to increases in mean oyster biomass and biomass of transient fish species. The model also revealed that a transient fish’s diet solely dependent on oyster reef-derived prey could limit the biomass of transient fish species, emphasizing the importance of habitat connectivity in estuarine areas to enhance transient fish species biomass. Simple bioenergetics models can be developed to understand the dynamics of a system and make qualitative predictions of management and restoration scenarios.

Science Advances 4: eaar1988. \| Abstract	2018-06-30	Should they stay or should they leave? That is a critical question facing young birds in a nest as they mature. The answer has ramifications for juvenile mortality, an important influence on demography and fitness, but differs among species and the reasons why are unclear. The probability of young being eaten increases with each day they remain in the nest. We show that species at greater risk leave the nest at a younger age with less developed wings that cause poorer flight performance and greater subsequent mortality. Experimentally delayed fledging verifies that older age and better developed wings reduce juvenile mortality. Fitness benefits of staying in the nest to reduce fledgling mortality are opposed by nest predation costs, and parents and offspring conflict on the optimal resolution. Ultimately, fledging age and associated offspring development balance mortality in and out of the nest in a compromise between parents and offspring.

Experimental Results. \| Abstract	2020-07-31	Understanding the effects of predicted rising sea levels, combined with changes in precipitation and freshwater inflow, on key estuarine ecosystem engineers such as the eastern oyster would provide critical information to inform restoration design and predictive models. Using oyster ladders with shell bags placed at three heights to capture a range of inundation levels, oyster growth of naturally recruited spat was monitored over the course of 6 months. Oyster numbers and heights were consistently highest in bottom and mid bags experiencing greater than 50% inundation (mid: 63 ± 7 %; bottom: 95 ± 3 %). Identifying thresholds for optimal oyster growth and survival to enhance restoration engineering would require finer scale evaluation of inundation levels.
Marshall, D.A., Sutor, M., La Peyre, J.F., La Peyre M.K. 2020. Using reproductive potential to assess Louisiana oyster population sustainability. Restoration Ecology \| Abstract	2020-07-31	<b>Abstract</b>Ensuring that oysters remain sustainable in the face of significant coastal restoration activities, high local subsidence rates, and predicted sea level rise requires a deeper understanding of basic population demographics including reproductive potential.We quantified fecundity (eggs ind<sup>-1</sup>) of oysters at high and low salinity sites during a fall and spring spawn season. We assessed the relationships between oyster size, the relative proportion of females across size classes, and fecundity. Finally, we quantified reproductive potential (eggs m<sup>-2</sup>) of an engineered reef by connecting fecundity with annual oyster population demographic data as a means to assess population sustainability.The proportion of females generally increased with shell height, achieving a population with >50% females in Biloxi oysters >75 mm, and Grand Isle oysters >100 mm. Fecundity across both sites and seasons ranged from ~2,000 to >55 million eggs oyster<sup>-1</sup>. Mean fecundity generally increased with shell height, varying significantly by site with Grand Isle (high salinity) oysters having greater fecundity than Biloxi (low salinity) oysters. Fecundity did not differ by season. Mean reproductive potential (eggs m<sup>-2</sup>) was driven by density (i.e., reef type) and size distribution. Reef technologies with high densities and higher counts of market oysters had reproductive potential 5X greater than those with low densities and low counts of juvenile oysters.Synthesis and applications: With increasing changes in water quality from coastal management and climate, impacts on oyster reproduction may critically impact population sustainability. Reproductive potential provides critical data to assess individual reef ecosystem services, and potential for maintenance of local metapopulations.

North American Journal of Fisheries Management ISSN: 0275-5947 print; 1548-8675 online DOI: 10.1002/nafm.10460. \| Abstract	2020-05-31	We used an bioenergetics-based modeling approach to track American Shad Alosa sapidissima offspring within a template of spatial and temporal habitat conditions defined by a combination of abiotic conditions and prey availability models. We simulated spawning at each river kilometer (RKM 138-280) on each day (1 April-31 August) to understand how spawning date and location drive larval recruitment differentially across years and decades. For both temperature and flow, inter-annual variation was large in comparison to interdecadal differences. Variation in simulated recruitment was best explained by a combination of season-specific temperature and location in along the course of the river. Greatest potential recruitment occurred in years in which June temperatures were relatively high. In years when June and July were warmer than average, maximum recruitment resulted from spawning taking place at the upstream portion of the modeled reach. Model scenarios (stationary or passive-drift larvae and dams or no dams) had predictable effects. When dams were present, but offspring were stationary, the area directly above the dams resulted in poor recruitment, due to the habitat being inappropriate for eggs. When offspring exhibited passive drift, they traveled far downstream. If dams were present, they frequently ended their movement at the dams. When larvae moved downstream but their movement was not limited by dams, spatial differences in expected recruitment relative to spawning sites were reduced. Our results demonstrate the importance of spatiotemporal environmental heterogeneity for producing positive recruitment over the longterm. In addition, our results suggest the importance of successful passage of spawners to historical spawning sites upstream of Vernon Dam in the Connecticut River, especially as conditions shift with climate change.

Interactive effects of water temperature and salinity on growth and mortality of eastern oysters, Crassostrea virginica: a meta-analysis using 40 years of monitoring data. Journal of Shellfish Research 36:1-15. \| Abstract	2017-10-31	Despite nearly a century of exploitation and scientific study, our understanding of the combined effect of temperature and salinity on eastern oyster (Crassostrea virginica) mortality and growth remains regionally specific at best. In the northern Gulf of Mexico, for example, the complexities of these relationships are assumed from Atlantic estuaries where oysters generally experience cooler water temperatures and greater salinities. Using long-term (1988-2015) monitoring data from Louisiana’s public oyster reefs, we develop regionally specific models of temperature and salinity driven mortality (sack oysters only) and growth for spat (≤ 25 mm), seed (25-75 mm) and sack (> 75 mm) oyster size classes. Our results demonstrate that the optimal combination of temperature and salinity where Louisiana oysters experience reduced mortality and fast growth rates is skewed towards lower salinities and higher water temperatures. Outside of that optimal range, oysters are commonly exposed to combinations of temperature and salinity that are correlated with high mortality and reduced growth. How these combinations affect growth, and to a lesser degree mortality, appears to be size-class dependent. Given current climate predictions for the region and ongoing large-scale restoration activities in coastal Louisiana, our growth and mortality models are a critical step towards ensuring sustainable oyster reefs for long-term harvest and continued delivery of the ecological services in a changing environment.

Fisheries Management and Ecology 25:150-157. DOI: 10.1111/fme.12274 \| Abstract	2018-03-31	Age and growth of Shoal Bass (Micropterus cataractae Williams & Burgess 1999) in the upper Chattahoochee River basin was assessed with non-lethal means (scales and mark-recapture) where some populations are imperiled. Mark-recapture data allowed us to estimate accuracy and determine effects of any scale-based inaccuracies on resulting growth models. Scale-based age estimates were accurate for 57% of the samples and errors included equal numbers of over- and underestimates of age (1 to 3 years). von Bertalanffy growth models using age-dependent data produced similar results to that from an age-independent data for ages 3-8. The use of scales thus complemented the results from mark-recapture by providing estimates of longevity to compare with growth models produced from change in body size over time. These populations of Shoal Bass live longer and grow slower than other populations, suggesting regional approaches to management.

Transactions of the American Fisheries Society. 145: 537-544. DOI:10.1080/00028487.2015.1135189 \| Abstract	2016-04-30	The Alligator Gar Atractosteus spatula is a species of conservation concern throughout its range, and better definition of otoliths during early development would aid understanding its life history and ecology. We conducted X-ray computed tomography scans, scanning electron microscopy, and light microscopy to examine the three pairs of otoliths and how they developed over time in relation to fish size and age. The sagittae are the largest, possessing distinct dorsal and ventral lobes covered with small otoconia concentrated in the sulcul region. The sagittae exhibited allometric growth, increasing more rapidly in the ventral lobe than in the dorsal. The asterisci were smaller and also exhibited small otoconia on their surface, but much less than the sagittae. The lapilli were oriented laterally, in contrast to the sagittae and asterisci, which were oriented vertically, with a hump on the dorsum and very large otoconia on the lateral surface that appeared to fuse into the main otolith as the fish grew. Based on size measurements and ring counts in all three pairs of otoliths from 101 known-age Alligator Gar sampled weekly through 91 d after hatch, we developed regression models to examine otolith growth and predict age. All relationships were significant and highly explanatory, but the strongest relationships were between otolith and fish size (for measurements from sagittae) and for age predictions from the lapillus. Age prediction models all resulted in a slope near unity, indicating that ring deposition occurred approximately daily. The first ring in sagittae and lapilli corresponded to swim-up, whereas the first ring formed in asterisci approximately 8 d after swim-up. These results fill a gap in knowledge and can aid understanding of evolutionary processes as well as provide useful information for management and conservation.

The lower Mountain Fork of the Little River below Broken Bow Dam is one of two year-round tailwater trout fisheries in Oklahoma, and the only one with evidence of reproduction by stocked rainbow trout (Oncorhynchus mykiss). Whether stocked trout use tributaries in this system for spawning is unknown. Furthermore, an inventory of the resident fish communities in these tributaries is lacking. To address these gaps, we surveyed 10 tributaries, from intermittent through third order, for fishes during presumed spawning periods of rainbow trout; we used backpack electrofishing in February and April 2015 and 2016 to determine the composition of the fish assemblages and whether trout were present. Stocked adult trout were found in three tributaries in 2015; wild juvenile rainbow trout were found in Bee Branch in 2015 and in an intermittent tributary of Spillway Creek, just above the “Cold Hole,” in 2016. Fish assemblages were dominated by highland stonerollers (Campostoma spadiceum) in larger, wider systems and by orangebelly darters (Etheostoma radiosum) in smaller, narrower streams. These data fill an information gap in our understanding of small streams in the Ouachita Mountains, and they demonstrate that some streams are suitable for rainbow trout reproduction.

We sought to determine if bait type, ZOTE© soap and ground cheese logs, would influence catch of channel catfish (CPUE and mean TL) and bycatch of fishes and aquatic turtles. We sampled with tandem hoop nets in 13 Kentucky reservoirs (5–73 ha) using a crossover design and two sampling events. We found no difference in channel catfish catch rates between bait types, but mean sizes of fish caught using ZOTE© soap were approximately 24 mm longer compared to cheese. Fish bycatch was similar between bait types, but tandem hoop nets baited with ZOTE© soap caught up to 61% fewer turtles and mortality of turtles that were captured was up to 12% lower than those baited with cheese. Depth of net set, water temperature, and Secchi depth were environmental factors measured that affected catch and bycatch, but varied among species. Using ZOTE© soap as bait in tandem hoop nets appears to be a fairly simple and straightforward method for maintaining high catch rates of channel catfish while minimizing turtle mortality.

DOI: 10.1002/tafs.10108 \| Abstract	2018-11-30	Gar (Lepisosteidae) are increasingly being managed as native components of the ecosystem rather than being reviled as they once were. There is a paucity of information on early life history for many species, which would aid their conservation and management. Daily rings in otoliths are useful for determining many early life-history parameters, such as growth rates and date of hatch, but properly interpreting these structures requires additional information on otolith formation. Gar represent an ancient lineage and their otoliths are unlike those of teleost fishes that have been better studied. We used computed tomography (CT) X-ray scanning and oxytetracycline (OTC) marking of a series of known-age fish from hatch through 10-12 days post-hatch (dph) to understand the formation of otoliths in Spotted Gar Lepisosteus oculatus, a species that is of management concern in several parts of its range in North America. Otoliths, sagittae and lapilli, began as a loose associations of otoconia at hatch, fused and hardened into single crystals by 4 dph, in concert with the transition from attached larvae to free-swimming juvenile. Asterisci otoliths were not observed in any of the individuals examined through 12 dph. Oxytetracycline marks were not observed on individuals treated at hatch and variable marks were detected at 1 dph through 5 dph. By 6 dph, 100% of individuals exhibited OTC marks on sagittae and lapilli. Daily rings could not be discerned until fish were marked 4 dph, after which, daily age estimates increased linearly with fish age. Results of this study verify that otoliths (sagittae and lapilli) of Spotted Gar and their daily rings form several days after hatch, in relation to the transition from sessile, attached larvae to free-swimming juvenile.

We analyzed nest data from a designed experiment to test for differences in habitat utility for 14 bird species in forest plots managed for biofuel feedstock production using switchgrass (Panicum virgatum) intercropping within a loblolly pine (Pinus taeda) plantation in Mississippi, USA. 2. We adapted hierarchical community models that use hyper-parameters to incorporate information from a suite of common and rare species to understand community-level nest survival. This approach incorporates information from rare species that are often discarded due to low sample sizes, but can inform community-level demographic parameters. We illustrate using this approach in generating both species-level and community-wide estimates of daily survival rates for songbird nests. We were able to include rare species with low sample size (minimum n = 4) to inform a community-level hyperprior, allowing us to estimate effects of nest placement covariates on daily survival at the community level, then compare this with a single-species approach using surrogate species. 3. Species-level survival and parameter estimates were similar to those generated by single species models, but estimates for species with low sample size may be unduly influenced by other species exhibiting varying survival responses to similar ecological conditions. 4. Covariates of nest placement indicated that presence of switchgrass at the nest site level (< 4 m) reduced daily nest survival, although intercropping at the forest stand level increased daily nest survival. Stand-level disturbances associated with establishing switchgrass and site-level microstructure may differentially promote or inhibit assemblages of nest predators within a diverse nest predator guild. 5. Synthesis and applications Hierarchical community models present a viable method for estimating community nest survival estimates and effects of covariates while incorporating limited data for rare, or rarely detected, species.

Ibis 158: 135–143. \| Abstract	2016-01-31	Avian life history theory predicts that high adult survival and populations near carrying capacity favour reduced clutch size and increased investment per offspring to increase juvenile survival. Consistent with this hypothesis, south temperate and tropical birds are commonly longer-lived and have smaller clutch sizes. Yet, comparative analyses of juvenile survival are largely lacking. We measured post-fledging survival for eight south-temperate passerines in South Africa, and combined our measurements with estimates from a review of published studies from around the world to test two predictions: 1) survival through the first few weeks post-fledging increases with adult survival and reduced brood size, and 2) south temperate and tropical species exhibit higher post-fledging survival than north temperate species associated with higher adult survival and smaller brood sizes. Using post-fledging survival estimates for 73 passerine species, we found that variation in post-fledging survival across species was explained by region and not by adult survival or brood size. South temperate species had higher post-fledging survival than both north temperate and tropical species. Post-fledging survival did not differ between north temperate and tropical species, but tropical species were under-represented. Our results highlight that adult and juvenile mortality do not simply covary, but they both differ between the northern and southern temperate regions. Given the importance of age-specific mortality to life history evolution, understanding these geographic patterns of mortality is important.

Emu 114: 394-401. \| Abstract	2016-12-31	Among cooperatively breeding species, helpers are hypothesised to increase the survival of breeders by reducing breeder workload in offspring care and increased group vigilance against predators. Furthermore, parental nepotism or other benefits of group living may provide a survival benefit to young that delay dispersal to help on the natal territory. We tested these hypotheses in the Karoo scrub-robin (Cercotrichas coryphaeus), a long-lived, facultative cooperatively breeding species of southern Africa in which male offspring delay dispersal until they obtain a breeding vacancy in a nearby territory, and helpers make substantial contributions to parental care. The hypothesis that helpers improve breeder survival was not clearly supported; annual apparent breeder survival in the presence of helpers (0.82) did not differ detectably from breeders without helpers (0.77). Survival of breeders that lost helpers (0.71) was lower, which may reflect a benefit of helpers or a poor territory. The hypothesis that helpers may gain a survival benefit from deferred breeding was not supported; male helpers had similar apparent survival as male breeders in the first year, and lower survival thereafter. Nonetheless, the relatively high survival of males through the first year following fledging (0.50) or independence (0.65) is consistent with high juvenile survival among species with delayed dispersal.

We used this comparison to test key predictions of three hypotheses thought to explain latitudinal variation in life histories among bird species, the seasonality and food limitation hypothesis, nest predation hypothesis and adult mortality hypothesis. Contrary to the general pattern of smaller clutch size and lower adult mortality among south-temperate birds living in less seasonal environments, Cape Penduline Tit has a larger clutch size than Verdin, a clutch size similar to Eurasian Penduline Tit and higher adult mortality than both species. Cape Penduline Tit differs most notably in parental behavioural strategy, exhibiting bi-parental care at all stages of nesting together with facultative cooperative breeding, whereas Eurasian Penduline Tit has uni-parental care and Verdin has a combination of female-only incubation but bi-parental nestling care. Consequently, Cape Penduline Tit exhibits greater nest attentiveness during incubation, a greater per-nestling feeding rate and greater post-fledging survival. The relatively large clutch size, high nestling feeding rates and associated high adult mortality in Cape Penduline Tit in a less seasonal environment support key predictions of the adult mortality hypothesis and run counter to key predictions of the seasonality and food limitation hypothesis in explaining life history variation among Remizidae species. These results add to a growing body of evidence of the importance of age-specific mortality in shaping life history evolution.

Coastal Management 43:471-497. \| Abstract \| Publisher Website	2015-10-31	We explore how marine ecosystem–based management (EBM) is translated from theory to practice at six sites with varying ecological and institutional contexts. Based on these case studies, we report on the goals, strategies, and outcomes of each project and what we can learn from these efforts to guide future implementation and assessment. In particular, we focus on how projects dealt with the challenges of working across geographic scales and diverse governance arrangements. While we hypothesized that EBM in the United States would be distinct from EBM in developing countries due to differences in social and political factors, we found that sites faced similar challenges. Variation among sites appeared to be more closely related to the preexisting management context and the scale at which the projects began rather than to clear differences between the United States and developing country contexts. EBM project implementers were able to overcome many of these challenges by focusing on a limited number of specific objectives, starting at a small scale, pursuing adaptive management, and monitoring a diverse set of indicators. These findings are directly relevant to current and future EBM efforts in these and other places.

Journal of Avian Biology 48:597–610. doi:10.1111/jav.00975 \| Abstract \| Publisher Website	2017-02-28	Life history patterns and their associated tradeoffs influence population dynamics, as they determine how individuals allocate resources among competing demographic traits. Here we examined life history strategies in common goldeneyes Bucephala clangula (hereafter goldeneye), a cavity-nesting sea duck, in the northern boreal forest of interior Alaska, USA. We used multistate capture–mark–recapture models to estimate adult survival, breeding probability, first-year survival, and recruitment probability using a long-term nest box study (1997–2010). We detected annual variation in adult survival, which varied from 0.74 ± 0.12 (SE) to 0.93 ± 0.06. In contrast, breeding probability remained relatively high and invariant (0.84 ± 0.11) and was positively related to individual nest success the year prior. Nonbreeding individuals in one year were more likely to remain a nonbreeder, than attempt to breed the following year. First-year survival decreased with smaller residual duckling mass and larger brood sizes. Probability of recruitment into the breeding population conditioned on survival was constant during the study (0.96 ± 0.06), and did not vary among ages 2–5 yr-old. Overall, goldeneyes exhibited high, but somewhat variable, adult survival, and high breeding and recruitment probabilities, which is consistent with observed patterns in bet-hedging species that breed annually in high quality breeding environments, but whose reproductive output is often influenced by stochastic events. Demographic estimates from this study are among the first for goldeneyes within Alaska. Life history patterns are known to vary geographically, therefore, we recommend further examination of life history patterns within the distribution of goldeneyes.

Journal of Avian Biology 48:1394–1405. doi: 10.1111/jav.01359 \| Abstract \| Publisher Website	2017-09-30	Traits with the greatest proportional effects on fitness are typically conserved (Stearns 1992), and traits with larger temporal variation frequently play a dominant role in population dynamics (Cooch et al. 2001). We examined recruitment patterns and population growth in Common Goldeneyes (Bucephala clangula; hereafter goldeneye), using Pradel mark-recapture models from a long-term nest box study (1997-2010). Our objectives were to estimate recruitment (f) and population growth (λ) relative to recruitment origin group (in-situ or unknown), investigate environmental and density dependent effects on these parameters, and evaluate potential immigration patterns. We detected group-specific differences for f (in-situ: 0.47± 0.13 SE, unknown: 0.31 ± 0.04), and the proportion of boxes occupied by goldeneyes the year prior to recruitment had a significant negative effect on recruitment for the in-situ group (β = -1.04; 85% CI -1.29, -0.78), and a positive effect for the unknown group (β = 0.45; 85% CI 0.30, 0.61). The negative box occupancy effect in the year prior to recruitment, when in-situ yearling goldeneyes prospect for potential nest sites, suggests that local nesting densities may limit recruitment of locally hatched females. We identified two competitive models for λ, which averaged 1.04 ± 0.03 and included interactions between recruitment origin group and a linear temporal trend, and the proportion of ducklings marked two years prior. By evaluating all levels of marking effort on λ, we determined that even if all hatched ducklings were marked in a given year, the resulting in-situ λ was consistently lower than all observed population-level λs during the study, indicating that individuals produced outside of study area nest boxes contributed to λ. Though female goldeneyes are considered highly philopatric, our results suggest that female natal and breeding dispersal may be more prevalent than previously thought, and the spatial scale at which these processes occur requires further investigation.

Integrating the effects of salinity on the physiology of the eastern oyster, Crassostrea virginica, in the northern Gulf of Mexico through a Dynamic Energy Budget model. Ecological Modelling 363:221-233. \| Abstract	2017-09-30	We present a Dynamic Energy Budget (DEB) model for the eastern oyster, Crassostrea virginica, which enables the inclusion of salinity as a third environmental variable, on top of the standard food and temperature variables. Salinity changes have various effects on the physiology of oysters, potentially altering filtration and respiration rates, and ultimately impacting growth, reproduction and mortality. We tested different hypotheses as to how to include these effects in a DEB model for C. virginica. Specifically, we tested two potential mechanisms to explain changes in oyster shell growth (cm), tissue dry weight (g) and gonad dry weight (g) when salinity moves away from the ideal range: 1) a negative effect on filtration rate and 2) an additional somatic maintenance cost. Comparative simulations of shell growth, dry tissue biomass and dry gonad weight in two monitored sites in coastal Louisiana experiencing salinity from 0 to 28 were statistically analyzed to determine the best hypothesis. Model parameters were estimated through the covariation method, using literature data and a set of specifically designed ecophysiological experiments. The model was validated through independent field studies in estuaries along the northern Gulf of Mexico. Our results suggest that salinity impacts C. virginica’s energy budget predominantly through effects on filtration rate. With an overwhelming number of environmental factors impacting organisms, and increasing exposure to novel and extreme conditions, the mechanistic nature of the DEB model with its ability to incorporate more than the standard food and temperature variables provides a powerful tool to verify hypotheses and predict individual organism performance across a range of conditions.

By selecting locations or ‘habitats’ with many benefits (e.g., food, shelter, mates) and few costs (e.g., predation), animals improve their ability to survive and reproduce. Biologists track animal movement using radio telemetry technology to study habitat selection so they can better provide species with habitats that promote population growth. We present a curricula in which students locate “animals” (transmitters) using radio telemetry equipment and apply math skills (use of fractions and percentages) to assess their animal’s habitat selection by comparing the availability of habitat types with the proportion of ‘animals’ found in each habitat type.

In a meta-food web – an integrated network of local food webs – spatial heterogeneity in physical processes may have profound effects on food web function and energy flow. In the Arctic, surface water connectivity plays a vital role in determining fish assemblage composition, and potentially, food web structure. We examined lentic food web complexity associated with heterogeneity in surface water connectivity among Arctic lakes at the local scale, by contrasting lakes over a stream-lake connectivity gradient, and at the regional scale, by contrasting two locations with different surface water conditions (i.e., wet and dry) on the Arctic Coastal Plain of Alaska. Among lakes and across locations, increased hydrologic connectivity between streams and lakes increased the number of fish species and increased the complexity of the food web. The interaction of the region's hydrologic connectivity, local stream-lake connections, and the trophic niches of relevant fish species produced integrated, complex meta-food webs. Fully understanding mechanisms that support meta-food web stability are crucial when assessing future changes to Arctic stream-lake networks and the function and persistence of aquatic food webs.

American Fisheries Symposium 89: 69-81 \| Abstract	2019-12-31	Understanding the diel activity of a species can shed light on potential interactions with other species and inform management practices. To understand the diel activity of Northern Snakehead <i>Channa argus</i>, feeding habits and movement patterns were observed. Two hundred seventy-three Northern Snakehead were captured by boat electrofishing during May and June of 2007 and 2008. Their gut contents were extracted and preserved. The level of digestion of each prey item was estimated from fresh (1) to >50% digested (4) or empty (5). Random forest models were used to predict feeding activity based on time of day, tide level, date, water temperature, fish total length, and sex. Diel movement patterns were assessed by implanting Northern Snakehead with radio transmitters and monitoring them every 1.5 hours for 24 hours in both March and July 2007. Movement rates were compared between March and July and among four daily time periods. Independent variables accounted for only 6% of the variation in feeding activity; however, temporal feeding patterns were apparent. No fresh items were observed in guts between 12:30 and 7:30 am, and the proportion of empty stomachs increased at the end of May coinciding with the onset of the spawning season. Overall, fish moved greater distances during the July tracking period compared to March. Fish showed a greater propensity to move during daylight hours than at night during the March tracking period. A similar but non-significant (<i>P</i> > 0.05) pattern was observed in July. Movement and feeding data both indicated greater activity during daylight hours than at night, suggesting that Northern Snakehead is a diurnal species. Based on our preliminary findings, we hypothesize that a) diurnal species are more susceptible than nocturnal species to predation by Northern Snakehead and b) Northern Snakehead are more likely to compete for food with diurnal than nocturnal predators.

Urban Ecosystems. 22:1083 - 1096 \| Abstract \| Download	2019-11-30	Developing effective butterfly monitoring strategies is key to understanding how butterflies interact with urban environments, and, in turn, to developing local conservation practices. We investigated two urban habitat types (public gardens and restored/reconstructed prairies) and compared three survey methods (Pollard transects, purposive point counts, and random point counts) to determine which was most productive for detecting butterflies and assessing family diversity. We conducted 66 butterfly surveys by using each method (198 total) from May through September in 2015 and 2016 at six sites (three public gardens and three prairies) inAmes, Ankeny and Des Moines, Iowa. All survey methods were used on 11 sampling dates at each site. Overall, we observed 2,227 butterflies representing 38 species: 1,076 in public gardens and 1,151 in prairie areas.We used a smaller data set standardized for survey effort, including 1,361 of these sightings, to compare survey methods and habitat types. Although there were no significant differences in number of butterfly sightings between the two habitats, more sightings (798) were documented by using purposive point counts when compared to Pollard transects (297) or random point counts (266) (for both comparisons, p < 0.0001). Occupancy modeling also indicated that purposive point counts were most effective in detecting certain species of butterflies, most notably those within the Pieridae (whites, sulphurs) and Papilionidae (swallowtails). We conclude that public gardens and restored/reconstructed prairies in urban settings can provide important butterfly habitat, and that purposive point-count surveys are most effective for detecting butterflies in these relatively small-scale landscape features.

Global Ecology and Conservation 23: https://doi.org/10.1016/j.gecco.2020.e01070 \| Abstract \| Publisher Website	2020-09-30	The warming climate presents a challenge to conservation of all threatened and endangered species but particularly to those that exhibit temperature-dependent sex determination such as sea turtles. Changes in temperature may result in changes in the sex ratio of the population which can directly affect reproductive rate, abundance and population dynamics. The NW Atlantic loggerhead turtle population is listed as threatened under the U.S. Endangered Species Act, and one of the smallest subpopulations in this assemblage nests in the northern Gulf of Mexico. Here, we describe the incubation environment of northern Gulf of Mexico loggerheads nesting at several different beaches in Northwest Florida. Temperature dataloggers were placed inside and adjacent to nests on different nesting beaches across Northwest Florida. In addition, incubation durations were recorded from nests deposited on those same beaches. Internal nest temperatures were higher than those in the sand, however sand temperatures were correlated with incubation durations. Sand temperatures differed along the vertical beach profile and according to depth. Temperatures also differed along a geographic gradient across Northwest Florida and in relation to distance from the Apalachicola River. Incubation durations followed a similar pattern. Mean monthly temperatures at all sites were at or lower than 29 °C (range 23.1 °C–29.6 °C at the dunes; 23.8 °C–29.4 °C at mid-beach) which suggests nests in Northwest Florida may be producing a significant number of males, in contrast to the large number of females being produced on Florida’s Atlantic coast. The temperatures and incubation durations on these nesting beaches may be regulated by differing sources of sand and beach orientations across Northwest Florida. <br><br>

USGS FSP: IP-XX. \| Abstract	2018-01-31	Management actions aimed at eradicating exotic fish species from riverine ecosystems can be better informed by forecasting abilities of mechanistic models. We illustrate this point with an example of the Logan River, Utah, originally populated with endemic cutthroat trout (Oncorhynchus clarkii utah), which compete with exotic brown trout (Salmo trutta). The coexistence equilibrium was disrupted by a large scale, experimental removal of the exotic species in 2009-2011 (on average, 8.2% of the stock each year), followed by a increase in the density of the native species. We built a spatially-explicit, reaction-diffusion model encompassing four key processes: habitat heterogeneity, competition, dispersal, and a management action. The model was calibrated with detailed long-term monitoring data collected along the 35-km long river main channel since 2001. Our model, although simple, did a remarkable job reproducing the system steady state prior to management. Insights gained from the model predictions are that the exotic species is more competitive; however, the native species still occupies more favorable habitat and has superior growth. Dynamic runs of the model also recreated the increase of the native species following the management action, with two possible distinct outcomes: recovery or suppression/eradication of the exotic species. The processing of available knowledge using Bayesian methods allowed us to conclude that the chance for suppression/eradication of the invader was 15.4%. We show that accessible mathematical and numerical tools can provide highly informative insights for managers (e.g., outcome of their conservation actions), identify knowledge gaps as well as provide testable theory for researchers.

Ecology Letters 19: 403–413. \| Abstract	2016-01-31	Behavioral responses to reduce predation risk might cause demographic ‘costs of fear’. The rare tests in terrestrial systems have focused on single species, but differences in life histories and ecology among species could yield differing costs that need to be understood to develop a general framework. Thus, we used natural and experimental variation in predation risk to test phenotypic responses and associated demographic costs for 10 songbird species. Increases in risk generally yielded increased time spent incubating eggs, which caused shorter development periods that reduce nest mortality. Parents also fed offspring less often with increased risk, but offspring maintained growth of structures used to escape predators (wings, tarsi) while sacrificing mass growth. Reproductive output from non-depredated nests declined along risk gradients, but the severity of this cost varied across species. Ultimately, phenotypic responses to predation risk are common across co-occurring species, but responses and demographic costs vary substantially.

PeerJ 10.7717.peerj.1317. \| Abstract \| Download	2015-10-31	Oyster reefs provide valuable ecosystem services that contribute to coastal resilience. Unfortunately, many reefs have been degraded or removed completely, and there are increased efforts to restore oysters in many coastal areas. In particular, much attention has recently been given to the restoration of shellfish reefs along eroding shorelines to reduce erosion. Such fringing reef approaches, however, often lack empirical data to identify locations where reefs are most effective in reducing marsh erosion, or fully take into account habitat suitability. Using monitoring data from 5 separate fringing reef projects across coastal Louisiana, we quantify shoreline exposure (fetch + wind direction + wind speed) and reef impacts on shoreline retreat. Our results indicate that fringing oyster reefs have a higher impact on shoreline retreat at higher exposure shorelines. At higher exposures, fringing reefs reduced marsh edge erosion an average of 1.0 m y-1. Using these data, we identify ranges of shoreline exposure values where oyster reefs are most effective at reducing marsh edge erosion and apply this knowledge to a case study within one Louisiana estuary. In Breton Sound estuary, we calculate shoreline exposure at 500 random points and then overlay a habitat suitability index for oysters. This method and the resulting visualization show areas most likely to support sustainable oyster populations as well as significantly reduce shoreline erosion. Our results demonstrate how site selection criteria, which include shoreline exposure and habitat suitability, are critical to ensuring greater positive impacts and longevity of oyster reef restoration projects.

Frontiers in Marine Ecology, Special Issue: Gulf of Mexico Reefs, Past, Present and Future \| Abstract \| Download	2019-10-31	Essential fish habitat requirements within U.S. fisheries policy requires understanding of species-habitat associations. Recent focus on the restoration of eastern oyster (Crassostrea virginica) reefs derives from their role as ecosystem engineers, including their unique provision of hard bottom habitat for fish and decapod crustaceans. Within the shallow estuaries of the northern Gulf of Mexico, the eastern oyster is the dominant reef building organism occurring providing unique habitat. This study synthesizes data from the literature on fish and decapod crustacean use of oyster reefs across the northern Gulf of Mexico (nGoM). Relevant data from twenty four studies were identified, representing data collected from all five U.S. nGoM states over the last 28 years. Cumulatively, these studies document over 120,000 individuals from 106 fish and 41 decapod crustacean species. Densities ranged up to over 2800 ind m-2, with up to 52 unique species identified on a single oyster reef. While these data provide a first step in quantifying oyster reef support of nekton and developing benchmarks for oyster reef restoration, more targeted goals could be identified if habitat characteristics that may be driving the differences between reef assemblages, densities, and species richness could be identified. More explicit reef descriptions (e.g., rugosity, height, area, adjacent habitat) along with standardization of sampling gears and techniques would enable more explicit target setting, and provide clear benchmarks to guide habitat-species based policy goals. Establishing benchmarks of fisheries-habitat associations provides critical support for assessing damages (injury) to resources, provides targets for restoration projects, and overall, provides data to support assessments and predict future reef landscapes.

Journal of Sea Research. http://dx.doi.org/10.1016/j.seares.2019.101831 \| Abstract	2019-11-30	Coastal Louisiana supports some of the most productive areas for the eastern oyster, Crassostrea virginica. Changing conditions from restoration and climate change alter freshwater and sediment inflows into critical estuarine areas affecting water quality, including salinity and concentrations of suspended sediment. This study examined the effects of acute (1 hour) and chronic (8 weeks) exposure of suspended sediment concentrations on the eastern oyster’s respiration and clearance rates. Acute exposure at six sediment concentrations (0, 10, 50, 200, 500, 1000 mg L-1) and one salinity (15) indicated that sediment concentration significantly affected oyster clearance rates, with increasing clearance rates as suspended sediment concentrations increased up to 500 mg L-1. Respiration rates were not affected by sediment concentration (p = 0.12). Chronic exposure at two salinities (6 and 15) and three sediment concentrations (0, 50, 400 mg L-1) found no significant effect of sediment, salinity or their interaction on clearance rates (p > 0.71). Respiration rate was reduced at higher sediment concentrations (50 and 400 mg L-1 versus 0 mg L-1; p=0.0145) and lower salinity (p<0.0001). As clearance and oxygen consumption rates critically inform oyster energetic models, these data provide valuable insight to more accurately predict eastern oyster population dynamics and inform harvest models in the face of changing estuarine conditions. Changes in rates of growth through altered energetic demands ultimately can impact not just the economic viability of the industry, but also the ability for the populations to maintain sustainable reefs.

Waterbirds 39(3):241-249. \| Abstract	2016-09-30	The King Rail (Rallus elegans) is a secretive marsh bird of conservation concern and reproductive success is thought to be a limiting factor for the inland migratory population. Reproductive effort of King Rails was studied in southeastern Oklahoma from 2010 – 2012 using surveys, radio-telemetry, nest searching and brood observations. During 2011 -2012, we documented 29 King Rail territories. Ten nests were located between the first week in April and the first week in July with a mean clutch size of 10.3 (0.80 SE). Water depth at nests was shallow (<15 cm) and nest sites were in locations with more visual obstruction, more microtopographic variation, and more woody stems while open water cover was less than at random sites. Nine broods were followed that used rearing sites with deeper water, had a greater percent of tall emergent vegetation and more woody vegetation than random sites. Brood size dropped from an average of nine to two chicks by the second week. Daily chick survival rate across the breeding season was 0.969 (SE = 0.016) which resulted in a probability of a chick fledging of 21%. Reproductive effort by King Rails at our study site was low and of concern.

Fisheries Research 188:17-22. https://doi.org/10.1016/j.fishres.2016.12.004 \| Abstract	2017-04-30	Fishery independent gill net surveys provide valuable demographic information for population assessment and resource management, but relative to net construction, the effects of ancillary species, and environmental variables on focal species catch rates are poorly understood. In response, we conducted comparative deployments with three unique, inter-agency, survey gill nets used to assess walleye Sander vitreus in Lake Erie. We used an information-theoretic approach with Akaike’s second-order information criterion (AICc) to evaluate linear mixed models of walleye catch as a function of net type (multifilament and two types of monofilament netting), mesh size (categorical), Secchi depth, temperature, water depth, catch of ancillary species, and interactions among selected variables. The model with the greatest weight of evidence showed that walleye catches were positively associated with potential prey and intra-guild predators and negatively associated with water depth and temperature. In addition, the multifilament net had higher average walleye catches than either of the two monofilament nets. Results from this study both help inform decisions about proposed gear changes to stock assessment surveys in Lake Erie, and advance our understanding of how multispecies associations explain variation in gill net catches. Of broader interest to fishery-independent gill net studies, effects of abiotic variables and ancillary species on focal specie’s catch rates were small in comparison with net characteristics of mesh size or twine type.

We investigated nest survival of mallards in intensively cropped northern Iowa, USA, where wetland and grassland habitats were highly fragmented. We radiotracked female mallards nesting during 1998–2000 and located 318 nests in 6 types of land cover. Overall daily survival rate of nests was 0.9450.003 standard error (SE), corresponding to an estimated nest survival rate of 0.14. Hen success (i.e., the probability that an individual female will hatch a nest in one of her attempts) averaged 0.280.03 SE.Weused a model selection approach to examine covariates that might affect nest survival. Perimeter-to-area ratio (PAR) of the nest patch was the most important predictor of daily nest survival, with nest survival decreasing with increasing PAR. A greater percentage of nests hatched (18%) in habitats with low perimeter-to-area ratios (e.g., pastures, hayfields, Conservation Reserve Program fields, and managed grasslands) compared with habitats with high PAR (11%) such as drainage ditches, road-side ditches, fencerows, and waterways. Managing habitat in this region to increase mallard nest survival will be challenging, given the propensity of mallards to nest in linear habitats. If the climate change projections materialize in the 21st century, the southeastern portion of the Prairie Pothole Region could become a much more important breeding area for midcontinent mallards.

Ecosphere 7(2):e01226. 10.1002/ecs2.1226. \| Abstract	2016-03-31	ABSTRACT Understanding environmental drivers of spatial patterns is an enduring ecological problem critical to successful environmental conservation. Spatial discontinuities, both naturally occurring (e.g., river confluence, forest edge, drop-off) and anthropogenic (e.g., dams, roads), can strongly influence the distribution of highly mobile organisms that have land or seascape scale home ranges. Critical information about drivers of spatial patterns may be missed if only regularly-occurring environmental variables (e.g., depth, substrate, current velocity) are considered. A geomorphic discontinuity framework, expanded to include ecological patterns, provides a different way of examining organism-environment relationships that can capture the influence of these important but irregularly-distributed environmental conditions. Here, we test if highly mobile striped bass (Morone saxatilis) on a coastal feeding migration are consistently and predictably concentrated by spatial discontinuities. Specifically, we quantified the distribution of 50 acoustically-tagged striped bass relative to six types of physical features (sand bars, confluences, drop-offs, depth, channel proximity, region) during four monthly surveys at 40 sites within Plum Island Estuary (PIE). All striped bass survived tagging, were coastal migrants, displayed seasonal residency within PIE, and moved frequently within the estuary ecosystem. Striped bass were predictably and consistently clustered in the middle region of PIE at sites with high sandbar area, close to channel networks, adjacent to complex confluences, and at intermediate levels of bottom unevenness. In addition, the highest striped bass counts occurred at sites with the greatest additive heterogeneity (i.e., where multiple discontinuities co-occurred). Thus, the ecological discontinuity framework provided new insights about how mobile predators were distributed at the seascape scale that did not emerge from traditional habitat use perspectives. Consequently, our approach provides a fundamentally different way of looking at interactions among mobile animals and seascape-scale natural and anthropogenic physical features.

To identify site specific patterns of ecologically relevant heterogeneity, we asked three research questions for which we measured 23 geomorphic metrics at 40 sites within Plum Island Estuary (PIE), MA. Quantifying spatial patterns for complex physical features (e.g., confluences, bathymetric variation, channel networks, land features) provided several insights about seascape scale physical heterogeneity. First, individual metrics that described a single complex physical feature (e.g. confluence) showed different geographic patterns. When we used a cluster analysis to combine metrics from the same individual feature, we identified five patterns of confluences and three patterns of drop-offs throughout PIE. Second, because different types of physical features also varied in their geographic patterns, we developed and tested two indicators of overall physical heterogeneity. These overall heterogeneity indices combined physical features at specific sites via either a cluster analysis or an additive index. Third, these spatial patterns of overall physical heterogeneity were related to concentrations of striped bass (Morone saxatilis) within Plum Island Estuary. Specifically, more of these structure-oriented fish predators occurred at geographic locations with high overall heterogeneity (i.e., within a single heterogeneity cluster and at sites with the highest additive heterogeneity index values). With the creation and analysis of new metrics for individual and combined physical features, we have provided insights into spatially explicit patterns of physical heterogeneity that are relevant to seascape scale predator research and management.
