Using Qualitative Knowledge of Life History Traits to Predict Taxon Group Response to Levels of Coarse Woody Debris	December 2017	This project addresses how to utilize various qualitative and disparate sources of information to develop a reliable predictive framework for specific management actions or practices. For example, ecologists may be asked for their expert opinion on how species respond to the experimental addition or removal of coarse woody debris in a forest. There is a need to impose a more rigorous and objective approach that may be achieved through the applications of techniques from social science and statistics.	Forest management practices influence species abundance and biotic community richness in part through the deposition or removal of coarse woody debris (CWD). Knowledge of how species and taxonomic groups respond to CWD dynamics can help managers achieve forest management objectives, but it is unclear how to synthesize various qualitative and disparate sources of information into reliable predictive frameworks for management decision making. Expert opinion in the form of qualitative statements is often all that is available for the making of natural resource management decisions. Methods that translate this form of information into useful predictions may serve as a starting point for adaptive management endeavors, with the promise of supplanting the initial expert judgment with empirical evidence as decisions are made and outcomes are monitored. This research was a collaboration between U.S. Forest Service, the University of Georgia, and USGS. This work resulted in an estimation model that assigns species into a few discrete guilds based on similarities among empirically-estimated relationships and sensitive to prior (expert) information about guild compositions. The predictions generated by this model can be used to inform managers about responses by groups of species to forest management actions.
Decision Support for Public Alligator Harvesting in Georgia, Florida, and South Carolina	June 2017	Regulations for public alligator harvesting in the states of Georgia, Florida, and South Carolina are based on an assessment of current-year alligator population size against statistically-estimated historical trends in abundance. However, mechanistic models offer certain advantages over statistical models in that (1) they may be able to better predict harvest outcomes that are outside of historical experience, (2) they facilitate the making of optimal harvest decisions based on threshold conditions tied to the biology of the species, not the population's past performance, and (3) they provide a straightforward way to account for biological uncertainty about the response of populations to harvest management. In this project, we will employ a structured decision making approach to consider the problem of public alligator harvesting in the three participating state agencies. The approach will explicitly recognize the policy differences (management objectives and regulatory options) among the agencies, but it will take advantage of regional commonalities in population biology, habitat relationships, and sampling characteristics in the development of a set of decision models. Under this design, we expect that efficiencies can be created because the model set can be informed and improved by data contributed by any agency, and the models may indicate uncertainties toward which agencies can coordinate focused research efforts.
A Spatially Explicit Population Modeling Framework to Support Conservation Decision Making for Gopher Tortoises in Georgia	June 2017	Through a combination of meta-analysis and targeted field work, we propose to construct models that combine spatially explicit population processes and landscape elements to predict response of gopher tortoise populations to conservation actions. Probabilities of patch colonization and patch abandonment could be modeled as functions of the local population distribution, habitat and landscape attributes, and assessments of connectivity. Some of the parameters may be obtained from the literature or existing data sources; alternatively, some model parameters may quantified from targeted monitoring that we conduct. Where no information exists at all for a critical parameter, competing models could be developed around plausible values of the parameter. Over time, as conservation actions are carried out and their results are assessed, evidence will accumulate to better inform these models.
Responses of Targeted Herpetological Communities to Fire Management Practices in Pine-Oak Forests of the Great Smoky Mountains National Park	July 2014	Forest managers at the Great Smoky Mountains National Park are working to reintroduce a fire regime that once characterized the southwest portion of the park. However, managers are uncertain about the effects of fire - especially detrimental effects - on populations of amphibians and reptiles. This project will investigate relationships between prescribed fire management and herptile community response in this area of the park. The investigation will rely on field sampling and predictive modeling approaches. The outcome of this study, along with a companion project on bird community associations with fire management, will help inform park managers about responses by forest fauna to the reintroduction of fire.

Time-series Analysis for Monitoring Indicator Species	August 2015	Throughout the world, monitoring surveys produce count data that are used to provide essential information for understanding, restoring, and managing natural populations. Indicator species are typically monitored to assess changes in their status or distribution (e.g., to evaluate the effects of natural and anthropogenic stressors on the spatio-temporal dynamics of populations). Initially, this project will involve discussing management or monitoring situations with partner agencies. Specifically, this research project will involve analysis of priority data as identified by the US FWS. An overarching research goal for this project is to advance time-series analysis for monitoring of important indicator species.	None
Communicating and Using Uncertain Scientific Information in the Production of ‘Actionable Science’	August 2014	Conservation practitioners must navigate many challenges to advance effective natural-resource management in the presence of multiple uncertainties. Numerous climatic and ecological changes remain on the horizon, and their eventual consequences are not completely understood. Even so, their influences are expected to impact important resources and the people that depend on them across local, regional, and sometimes global scales. Although forecasts of future conditions are almost always imperfect, decision makers are increasingly expected to communicate and use uncertain information when making policy choices that affect multiple user groups. The degree to which management objectives are met can depend on 1) how critical uncertainties are identified and accounted for, and 2) effective communication among user groups, scientists, and resource managers. The objective of this project is to help facilitate strategic decision support and synthesize the state of the science related to communicating and using uncertain information in conservation decision making. By providing a forum on the communication of scientific uncertainty, we aim to traverse traditional disciplinary boundaries, with a focus on climate change in the southeastern United States. We expect this process to generate transferable guidance that will directly assist resource managers across agencies to identify common goals and shared research priorities.
Characterization of spatial and temporal variability in fishes in response to climate change	August 2017	Predicting population responses to climate change requires an understanding of how population dynamics vary over space and time. Although variability has historically been viewed as an impediment to understanding population responses to ecological changes, it can provide an important signal, rather than just being viewed as noise. In this project, we will build upon recently completed analyses of fish population data in the Great Lakes basin to help predict how spatial and temporal variation in fish populations may respond to climate change and other important drivers. We suggest that shifting variance structure can be indicative of population-level responses to climate change. Our proposed research will help elucidate the extent to which quantifiable responses in spatial and temporal variability occur in different forms of fish population data.	The number of fish collected in routine monitoring surveys often varies from year to year, from lake to lake, and from location to location within a lake. Although some variability in fish catches is expected across factors such as location and season, we know less about how large-scale disturbances will influence population variability. Our objective was to evaluate spatial and temporal variation in fish catches from large freshwater lakes that have experienced large-scale changing conditions. This was a collaborative project, involving partners from around the Great Lakes region, and it relied on established data sets of fish catches, including from Oneida Lake in NY, Lake Michigan, and the Bay of Quinte in Lake Ontario. This research helps elucidate the extent to which quantifiable responses in spatial and temporal variability occur in fish population data, which can help managers develop adaptation strategies to prepare for decisions about monitoring and management of dynamic ecological systems.
Trans-boundary management and conservation: linking large-scale dynamics to ecological monitoring and management	September 2014	A central challenge to natural resource management is to understand and predict ecological responses to management and environmental change over large spatial scales. It is recognized, however, that the management and conservation of many important ecological systems and the services they provide must be addressed at spatial scales that transcend jurisdictional and political boundaries. For example Landscape Conservation Cooperatives (LCCs) recognize that managing natural resources is complex and requires landscape-scale (i.e., trans-boundary) approaches. Although trans-boundary approaches are necessary to understand large-scale phenomenon (e.g., species range), it remains unclear in many cases how best to address the inherent complexities in managing ecosystems at large (e.g., regional) spatial scales. In addition to challenges associated with performing trans-boundary research, it is often unclear how to link large-scale system dynamics with on-the-ground decision-making processes, which are often done using adaptive management principles. For example, a critical component for successfully implementing adaptive management is the development of a rigorous monitoring program, which provides a critical feedback loop for learning about system dynamics. It is unclear, however, how the interplay between components acting at different, hierarchical scales will affect the ability of natural resource managers to detect changes in important state variables (e.g., animal abundance, occupancy, etc.) at trans-boundary spatial scales. Thus, our overarching objective is to use freshwater stream fish populations as model systems to develop a framework and tools for addressing the inherent challenges in performing trans-boundary research and for linking large-scale dynamics to ecological monitoring and management.

An assessment of water-borne and sediment-borne contaminant loading in the Conasuaga River: Implications for the Health of Aquatic Fauna	July 2000	The Conasauga River, an important tributary to the Coosa River and Mobile Basin drainage systems in northwest Georgia, has recently come to the forefront in river preservation and restoration. The Conasauga River is one of the few remaining free-flowing rivers in the southeastern United States and the second largest river flowing into the northern Gulf of Mexico (RCDC 1996). The River begins in the Blue Ridge Mountains of the Cohutta Wilderness Area in Murray County, Georgia, and flows northwest from its headwaters into Polk County, Tennessee. It is later joined by the Jacks River about 10 miles before turning south back into Georgia where it forms the boundary between Whitfield and Murray Counties. The Conasauga River then flows about 100 miles south through Georgia before it confluences with the Coosawattee to form the Oostanaula River. The Conasauga River drainage forms a 500,000-acre watershed that mostly consists of forested and agricultural lands. The watershed lies within the Southern Ridge and Valley Provinces (SRVP) and the Southern Blue Ridge Province. It has a diverse aquatic fauna and provides important habitat for breeding and migrating land birds (RCDC 1996). The upper Conasauga River is considered to be a high quality watershed that serves as the major headwaters to the Coosa/Alabama River system (RCDC 1996). The headwaters of the Conasauga are located primarily within the Cherokee and Chattahootchee National Forests. A portion of the acreage (119,000 acres) of the watershed is protected within the boundaries of these national forests and 3,400 acres are situated within Fort Mountain State Park. Portions of the river runs through urban and industrialized areas, and the water quality in these reaches may reflect activities within that watershed. Degraded water quality may cause variable levels of stress to fishes, mussels, and other macroinvertebrates. The overall condition of the Conasauga River’s watershed and associated water quality parameters are unknown. The watershed was last scored in October 1997, and a variety of environmental factors (i.e, designated use attainment, fish consumption advisories, source water condition, contaminated sediments, ambient water quality-toxic ambient water quality-conventional, and wetland loss) were used to assess its conditions. The data reported for four out of the seven listed areas (fish consumption advisories, water quality and condition) were insufficient to score the watershed’s condition. The vulnerability of the watershed was assessed by scoring the following areas: wetland aquatic species at risk, toxic loads over permit limits, conventional loads over permits, urban runoff index, population change, and hydrologic modification from dams. The overall condition and vulnerability of the Conasauga River’s watershed could not be determined because of insufficient data (EPA 1998). Therefore, additional data are needed on aquatic species at risk, the effects of urban and agricultural runoff, and dam-related hydrologic modifications on the watershed and related water quality status. Point source and non-point source pollution are potential problems in the Conasauga River. Point source pollution may stem from municipal sewage discharges, industrial waste water, and accidental spills of hazardous materials. Non-point source pollution are contaminants that are generated over large areas such as runoff from croplands, mismanaged forests, paved surfaces, septic tanks, construction activities, and unpaved roads. Other harmful items to the river ecosystem are septic leachate, pesticides and fertilizers, and chemicals disposed of within the watershed. Sedimentation, considered a non-point source pollution, is the largest contributor to pollution in rivers (FISRWG 1998). Sediment is defined as particles of rock and soil that have been dislodged and transported by water (FISRWG 1998). Many aquatic species e.g., fishes, mussels, dragonflies) are threatened by degradation of water and habitat quality because of erosion from riparian habitat and resulting siltation and sedimentation. Also, clearcutting forests or removal of vegetation for powerline right-of-ways may cause spring run or seasonal streams to disappear before fish eggs hatch (Rhett Jackson, personal communication). Siltation from roads, land development, and agricultural activities can smother fish eggs and kill the insects that provide and important food source for other organisms. Also, timber sedimentation that results from improper construction or placement of logging roads and failure to revegetate skid and haul roads in a timely manner may threaten the survival of aquatic species and degrade water quality in the river ecosystem.

Experimental assessment of variable flows on growth and survival	April 2001	In this study, we investigated the effects of pulsed, high-velocity water flow on the eggs and larvae of robust redhorse M. robustum and V-lip redhorse M. collapsum in three separate experiments that lasted from 21 to 38 d after egg fertilization. Hatch sucess and length at 24 h posthatch were quantified for eggs and larvae to discern any effects before larvae emerged from nests. Final length (of surviving larvae) and larval survival were quantified at the end of experimental periods to discern any effects after larvae emerged from nests. The research suppors the hypothesis that pulsed, high-velocity water flow can affect some aspects of catostomid early life development. Catostomid suckers are a diverse group of fishes endemic to most streams and rivers in the south-eastern United States. Reproduction occurs during late spring when water temperatures begin to rise. Water releases from hydropower-generating dams often occur in the spring as energy demand for cooling increases. These water releases increase the frequency of both high-velocity and low-velocity flow pulses while reducing their duration. Because of the low abundance of robust redhorses and other species of catastomids across thir historic ranges, special attention should be given to understanding the biological and physical conditions necessary for successful reproduction. Extended low-velocity flow periods are natural occurrences in low-rainfall years, and at least two species of catastomids (i.e., robust and V-lip red horse) might benefit from longer periods of stable low-velocity water flow during the spring spawning season. A return to natural flow patterns in dam-regulated rivers could help increase early larval survival and restore populations downstream from dams to their predam densities.	None
Morphological and meristic characteristics of four species	September 2004	In 1991, the imperiled robust redhorse was discovered in the Oconee River. Initially, nothing was known about this species but research conducted for the past eight years has answered many questions about the biology and ecology of these fish. Many questions remain including: 1) the fate of wild-spawned larvae and hatchery-produced juveniles, 2) their eventual contribution to the adult population, 3) dispersal behavior, habitat use and movement patterns of hatchery-reared juvenile redhorse 4) where and when to release hatchery-reared fish Information that we receive from this study will provide data to ongoing efforts to restore this species too much of its historic range.

Fish community response to commercial operation of the Richard	September 2007	We propose to reinstate the fish community monitoring conducted previously on J. Strom Thurmond and Richard B. Russell by the Georgia Cooperative Fish and Wildlife Research Unit. The goals for this 5-year effort are two fold. First, evaluate the effects of commercial pump-back operation of the Russell Project; and second, provide statistically-rigorous, scientifically-sound information on which to base management decisions about the operation of the Russell Project. The proposed study will encompass a variety of hydrological and climatological conditions and several year-classes of blueback herring and threadfin shad. The main tasks and objectives of this study are to: Task One: Evaluate fish community response in J. Strom Thurmond and Richard B. Russell Reservoirs to commercial operation of the Russell Project Objective: Monitor trends in fish populations in the Savannah River Arm of the Reservoir and the lower third of Richard B. Russell Reservoir. Task Two: Evaluate response of pelagic fishes to the installment and operation of a dissolved oxygen diffuser system in J. Strom Thurmond Reservoir. Objective: Determine if pelagic species with high dissolved oxygen requirements use habitat created by the operation of dissolved oxygen diffuser installed in J. Strom Thurmond Reservoir	None
Habitat use and movement patterns of adult robust redhorse released in the Oconee River, GA	December 2008	The status and fate of the adult population of robust redhorse Moxostoma robustum in the Oconee River, GA, has been the subject of much investigation (e.g., Jennings et al. 1996, 1998, Freeman 1998, Jennings et al. 2000, 2003, 2004a, 2004b, 2005) and discussion by the Robust Redhorse Conservation Committee (RRCC) for more than a decade. The central issues in recent discussions include habitat use during spawning and non-spawning periods, movement pattersn, the apparent reduction in the number of individuals spawning annually at the Avant mine site, and a steady decline in catch rates during brood stock collection. There is increased concern among RRCC members about the fate of the robust redhorse population in the Oconee River. Radio telemetry has been used successfully to document dispersal rates, movement patterns, and habitat use of hatchery-reared juvenile robust redhorse released in the Oconee (Hess et al. 2001) and Ocmulgee (Jennings and Shepard 2003) rivers. The use of radio telemetry to evaluate movement patterns and habitat use of adult robust redhorse in the Oconee River has been considered in the past, but was never undertaken for a variety of reasons. However, recent dramatic successes with radio telemetry studies of adults in the Savannah (Grabowski and Isley 2006) and Pee Dee (R. Heise-NC Wildlife Resources Commission, personal communication ) rivers have renewed interest in the use of this technique to address long-standing questions about habitat use and movement patterns of adult robust redhorse in the Oconee River. Accordingly, I propose to use radio telemetry to conduct a long-term (i.e., minimum of 1 year; second year dependant on additional funding) assessment of habitat use of adult robust redhorse stocked in the Oconee River. The specific objectives of this study are to 1) compare habitat use and movement patterns of stocked fish during specific periods (i.e., pre-, spawning, and post-spawning) of the year; 2) use radio tagged robust redhorse as guide fish that might lead to unknown spawning aggregations or population centers; and 3) determine the detection probability of radio-tagged individuals. This work will provide long-term data on dispersal behavior, habitat use, and movement patterns of adult robust redhorse released into the Oconee River. Although some of the fish used in this study may have been produced in a hatchery and grew to adulthood in the wild, they are expected to behave as naturally spawning adults. Therefore, the behavior of the radio-tagged fish should allow for inference about the seasonal habitat use and movement patterns of wild-produced adults in the Oconee River and elsewhere. Further, the tagged fish may lead to undiscovered spawning sites in the Oconee River. An estimate of the probability of capturing (i.e. detection probability) adult robust redhorse, if one is present, can be incorporated into estimates of population size. Taken in total, this information should allow for new inferences about the status and prognosis of the adult robust redhorse population in the Oconee River and facilitate better management decisions for restoring or enhancing this species.

A study of the ecological value of managed tidal wetlands compared to adjacent natrual marshes in the ACE Basin, SC	December 2010	The ACE Basin represents a unique opportunity for comparative studies between managed and unmanaged rice fields in the same location across a range of species and impoundment types (salinity, management objectives). However, a record growth in residential and commercial development on the fringes of the ACE Basin suggest the window of opportunity for science based decision-making in natural resources conservation and sustainability in this basin is quickly closing. The study we propose addresses two priority goals of SAMBI (South Atlantic Migratory Bird Initiative): (1) to provide optimal breeding habitat to maintain and increase populations of priority species, and (2) to provide high quality managed habitat to support requirements of species migrating through or spending winter in the region. outputs from this study will provide general information helpful to goals 2 and 6 outlined in the SSPD Resource Protection Funds. The ACE Basin is considered an Important an Important Bird Area for South Carolina by the National Audubon Society and American Bird Conservancy and supports numerous priority habitats and species listed in the South Atlantic Migratory Bird Initiative (SAMBI) of the Atlantic Coast Joint Venture.

Reproductive status of the Tripletail, Lobotes surinamensis Aggregation Offshore Jekyll Island Georgia	June 2011	The goal of this study is to describe the reproductive status of the tripletail aggregation near Jekyll Island, GA. The use of traditional histological methods requires researchers to collect and sacrifice large numbers of fish in order to produce meaningful results. However, non-lethal alternative may also be effective. Objectives: * Use of non-lethal measures of reproductive physiology (e.g, sex hormones, vitellogenin, ultrasound imaging) for assessment of tripletail reproductive status. * Validate non-lethal assessment methods by comparing results with gonad histology * evaluate efficacy of using sagittal otolith and first dorsal spine for determining age of tripletail in Jekyll Island aggregation.

Abundance, size structure, and spawning locations of Robust Redhorse stocked in the Ogeechee River, Georgia	December 2011	As part of the ongoing recovery effort for the robust redhorse, refugial populations have been established in several rivers in GA and SC. One such population was established in the Ogeechee River, GA, which has received about 40,000 fingerling robust redhorse during the period 1997-2004 (J. Evans, GDNR, pers. comm.). The overall status of this population, including size-structure, abundance, and habitat use is unknown. Further, successful reproduction and recruitment of wild-spawned fish has not yet been documented for this population. The goal of the proposed work is to evaluate reproduction and recruitment success for the population of robust redhorse stocked into the Ogeechee River. Specific objectives include: 1) estimating the size structure of the population to determine if reproduction and recruitment are occurring, 2) documenting spawning location(s), and 3) estimating the number of individuals in the adult population. The first component of the project will address the question of where in the river robust redhorse are spawning and will be based on the use of radio telemetry to locate spawning aggregations during the spawning season. During the fall, 30 robust redhorse will be captured with boat-mounted electrofishing and surgically implanted with ATS radio transmitters. The radio-tagged fish will be tracked monthly after the initial tagging until March 2011. Beginning in April 2011 and continuing through the end of June 2011, the fish will be tracked weekly to identify where in the system robust redhorse are spawning. These data should allow for habitat characterization and protection of spawning site(s) within the Ogeechee River. The second component will address the questions of: a) how many robust redhorse have survived in the Ogeechee and; b) what is the size structure of this population. This component will be based on a capture recapture approach in which boat-mounted electrofishing will be used to sample robust redhorse throughout their known range in the Ogeechee River. Additional surveys that are based on seines and other gear types will specifically target juvenile robust redhorse during late summer and fall.	None
Use of occupancy modeling to estimate the abundance distribution of introduced Robust Redhorse in Upper Reaches of the Ocmulgee River, GA	December 2011	This work will provide long-term data on dispersal behavior, habitat use, and movement patterns of hatchery-reared robust redhorse released into regional rivers. Specifically, husbandry efforts by the Warm Spring Fish Technology Center (USFWS) have produced many stockable-sized fish, but questions about their dispersal behavior, long-term habitat use and movement patterns have hindered decisions about when and where to release these fish. As a result, ongoing efforts to restore this species to much of its historic range (i.e., medium-sized and large rivers in the Piedmont and Upper Coastal Plain physiographic provinces of the Atlantic Slope) also have been hindered. Also, information about the habitat use of juveniles (relative to that of adults) will help interpret size-class data from the Oconee River population and facilitate better management decisions for protecting this species. Finally, this work will provide evidence of the value of stocking robust redhorse in selected river reaches for the purposes of establishing refugial populations.	None
Influence of Limnological Classification on sportfish production in lakes on Georgia's Public Fishing Areas	June 2012	Currently, the lakes in GADNR’s PFA system have not been classified, and fish production among the lakes in inconsistent. Efforts to manage the lakes for trophy sportfish (e.g., largemouth bass) have been hampered by uncertainties about how the lakes differ and which chemical or physical factors may be affecting fish production. Accordingly, we propose a 2-year study to measure a suite of chemical and physical factors for lakes in the PFA system and to classify the lakes based on similarities (or lack thereof) among these variable. The objectives for this work is to assign lakes on the PFAs into classes based on their chemical and physical characteristics and to determine which class of lakes is better suited for trophy sportfish management.

Water availability for ecological needs: A pilot study of the Upper Flint River System, GA	September 2010	Sustaining the ecological integrity of aquatic ecosystems while meeting human needs for water resources is a major challenge facing today's society. In many regions, including much of the eastern US, the growing demand for water supply and changing land use in urbanizing areas are altering hydrologic regimes in streams and rivers that society depends upon for ecosystem services, including support of native biodiversity. Meeting the challenge of balancing human needs for water resources with protecting aquatic ecosystems will require science-based information to answer the question: "What aspects of natural, or unaltered, hydrologic conditions are essential for the long-term maintenance of healthy aquatic ecosystems?" Aquatic resource managers have repeatedly expressed the need for science-based answers to the questions such as (1) how much can hydrologic conditions be altered in streams and rivers without impairing ecological function? and (2) what are the consequences of altering flows beyond those limits? River scientists around the world are currently engaged in developing methods to prescribe flow regimes that will protect ecological integrity of managed rivers (Postel and Richter 2003, Richter et al. 2003, Tharme 2003). This study provides an opportunity for USGS scientists to build on current concepts and, working with others, advance the science needed to understand linkages between hydrologic alteration and ecological integrity (See Box). In the case of the upper Flint River system, the Georgia Department of Natural Resources (GDNR) issues permits for water withdrawals and stipulates minimum instream flow requirements. The State currently is operating under an interim instream flow policy; GDNR has explicitly requested an objective effort to define the range of hydrologic regimes that should be protected in streams and rivers used for water supply. The purpose of this project is to advance the science needed to specify the hydrologic conditions necessary to support flowing water ecosystems in the context of municipal water-supply management. Specific objectives are to: 1) Develop conceptual economic models that relate hydrologic conditions, by way of hydraulic, geomorphic and water-quality change, to biological management objectives in a Piedmont river system. 2) Evaluate and determine the major driving factors (i.e., parameterize) in the conceptual ecological models using available data, and determine additional data needs. 3) Use the Upper Flint River system to demonstrate the potential for developing a decision-support system for use in evaluating options for water-supply development, incorporating ecological models developed and parameterized in Steps 1 and 2 to link hydrologic conditions to biological management objectives in an explicit landscape context. 4) Develop a long-term monitoring plan to allow model refinement and guide adaptive management relative to water supply in the Upper Flint River system.

Science support for the upper Coosa Basin, Phase I	December 2009	Watersheds in the Upper Coosa currently face increased threats due to increased development associated with the rapidly expanding Atlanta and Chattanooga metropolitan areas. Agricultural lands and forests are being converted to subdivisions, industrial parks, recreational facilities, and other developments at an accelerated rate. Riparian vegetation that stabilizes stream banks and moderates water quality is being cleared, runoff from upland areas converted to hardscapes has increased and is of poorer quality, and stream geomorphology is being altered by fill, piping, channelization, flashy stream flows, and other modifications. These changes in land use frequently cause accelerated erosion that silts in stream bottoms and reduces foraging and spawning success and/or increases point source and nonpoint source pollution in streams. In order to assist decision makers, managers and partners to better protect and recover the six listed fish, 6 listed mussels, and other rare species in the Upper Coosa Basin, the following objectives are proposed: Objectives: 1. Develop, evaluate, and model nonbiased stream-fish sampling methods 2. Develop a prioritized GIS inventory of manmade culverts, dams, and other structures impeding fish passage in priority sub-watersheds of the Upper Coosa Basin. The first project objective will evaluate three stream-fish sampling methods --backpack electrofisher, minnow seine, and snorkeling in the varied physiographic regions of the Upper Coosa (Piedmont, Ridge and Valley, Blue Ridge) over various channel substrates to (1) investigate the effect of species and physical habitat characteristics on capture efficiency, (2) synthesize capture efficiency models, and (3) estimate sample size requirements for detecting rare fish species. These data will be essential to - Evaluate both the success of localized habitat restoration projects (such as dam or culvert removals, channel restoration projects, or riparian restoration efforts) and watershed protection efforts (such as the basin-wide Etowah HCP guidelines). - Evaluate impacts of different development types to improve Service recommendations provided during Endangered Species Act or Fish and Wildlife Coordination Act consultation. - Collect adequate monitoring data to improve adaptive management efforts, particularly in the Etowah Basin when the HCP guidelines are implemented. The second project objective will inventory dams and road crossings with respect to fish passability within the sub-watersheds in the Upper Coosa Basin that are highest priority for protected fishes. Data will be entered into a GIS database and will include barrier location, hydraulic and geomorphic data (baseflow velocities, culvert elevation relative to stream bed, degree of bed scour), and an estimate of the length of stream habitat that would be reconnected by barrier removal. This database would allow identification of reaches where barrier removal could achieve the greatest habitat restoration for rare fish and would complement ongoing protection efforts in the Basin.

Park monitoring: Using decision models to assist vital signs monitoring in National Parks, a prototype using sea otters (Enhydra lutris) in coastal Alaska	December 2010	A fundamental goal of the National Park Service (NPS) is the long-term protection and management of resources in the National Park system. Achievement of this goal requires multiple approaches, including the conservation of essential habitats and the identification and elimination of potential threats to biota and habitats. To accomplish these, the NPS has implemented the Alaska Region Inventory and Monitoring (I&M) Program to monitor key biological, chemical, and physical components (i.e., vital signs) of ecosystems at 270 national parks. By monitoring these vital signs over large spatial and temporal scales, it is thought that park managers will be provided with 1) information on the status and trajectory of park ecosystems and 2) a greater understanding and insight into the ecosystem dynamics. Detecting and quantifying changes is important to conservation efforts. However, if the information provided by the monitoring does not coincide with management objectives, it would be of limited use for formulating remedial actions (Lee 1993). Similarly, monitoring data would provide limited insight into system dynamics if were not collected in such a manner as to resolve key uncertainties (e.g., structural uncertainty; Williams et al. 2002). There remains the need to develop tools to assist managers and their collaborators with current decisions and allow for the formal integration of monitoring data to improve the understanding of system dynamics, thereby improving future decisions. One such tool is decision analysis, which formalizes complex systems into a straightforward framework consisting of explicit quantitative relationships among management actions, sources of uncertainty, and potential outcomes (Clemen 1996). It allows natural resource managers to examine the expected effects of different management strategies, incorporate multiple objectives and values of stakeholders, determine the relative influence of various sources of uncertainty, and estimate the value of collecting additional data (Possingham 1997; Dorazio and Johnson 2003; Nichols and Williams 2006; Conroy et al. in press). Decision analysis can incorporate structural uncertainty by including more than a single representation of the system (Williams et al. 2002). These alternative representations of the system can differ completely in terms of the factors considered (e.g., density dependent vs. independent). For example, Peterson and Craven (2007) developed a decision model for the NPS Chattahoochee River National Recreation Area that included two alternative representations of streamflow effects, high flow vs. flow variability, on native fish recruitment. Monitoring data can be used to reduce these uncertainties and to learn about how the system works. If done in conjunction with management decision-making, this leads to a formal process that has been defined as adaptive management (Williams et al. 2002). Thus, the decision models would provide park managers with the means to quantify potential risks to ecosystems so that (1) the effects of different scenarios can be examined a priori, (2) changes park vital signs can be readily interpreted, and (3) monitoring data can be formally incorporated to reduce uncertainty and improve the understanding of system dynamics. For several important reasons (including many that influenced their selection as a "vital sign"), sea otters are an ideal prototype species for building and testing a decision-modeling approach to management of vital signs in the National Parks.

Multi-resolution Assessment of potential Climate Change Effects on Aquatic and Hydrologic Dynamics Part I: Estimating Ecological Change	September 2013	The southeastern US span broad ranges of physiographic settings and harbors exceptionally high levels of aquatic faunal diversity. Unfortunately, many of these ecosystems are under increasingly threat due to the rapid human development in the region. The effects of human development will be further exacerbated by continued and possibly, accelerating climate change. Natural resource conservation managers and planners can be effective at preserving these ecosystems in the face of climate change only if they can adapt current conservation efforts to minimize the varying threats posed by climate change. Indeed, climate change challenges many of the basic assumptions used by conservation planners and managers. Previous aquatic conservation planning efforts identified and prioritized areas for conservation based on the current environmental conditions, such as aquatic habitat quality, and assumed that conditions in conservation lands would be largely controlled by management actions (including no action). Climate change, however, will likely alter important system drivers (e.g., temperature and precipitation) making it difficult, if not impossible, to maintain desirable conditions in conservation lands into the future. Climate change will also influence the future conservation potential non-conservation lands, complicating conservation planning. To develop and adapt effective conservation strategies, managers need to consider the effects of climate change on future environmental conditions. Aquatic conservation planning and management have traditionally been separated into components (water use for human consumption and water availability for ecological needs) without formal integration of objectives and outcomes. Management actions, however, affect multiple aspects of the aquatic ecosystem such tat an action that is focused on desirable human use objectives will affect aquatic ecosystems and vice versa. For example, urban development changes vegetative cover and can alter runoff and streamflows-affecting water availability and ecological systems. Failure to consider alternative objectives in resource planning and management is inefficient and can potentially waste important opportunities or worse, can result in management actions that, while useful for achieving one objective, can negatively affect another important objective. Thus, there remains a need to develop a comprehensive approach to aquatic resource planning that incorporates multiple ecological and non ecological objectives. The objective of this research is to develop tools that aquatic resource managers can use to predict the effects of climate-change and management actions on water availability and aquatic communities at local landscape-scales. Using probabilistic projections of climate change, landcover dynamics, stream geomorphogy, and hydrology currently being developed for an integrated assessment in the Apalachicola-Chattahoochee-Flint river system, we will model effects on aquatic biota at fine resolutions (i.e., stream networks), providing estimates of biological responses for alternative climate scenarios and potential management actions. These models will then be placed in user-friendly formats for use by resources managers.	None
Decision Support Models for the Conservation and Recovery of Imperiled Mussels	September 2012	The effective conservation and management of at risk mussels in the lower Flint River Basin requires a credible assessment of the suitability of specific areas (habitats) to support each species and means to assess the potential risks, such as extinction due to fragmentation and isolation of populations. Such an approach should also allow for the integration of monitoring data so that reliable information on the status and distribution of at risk taxa can be updated as data are collected. The timely integration of monitoring data also is crucial for evaluating the success or failures of management actions to recover existing populations. The ultimate goal of this project will be to develop decision support tools for assisting biologists manage at risk mussels. Towards this end, this project will address four objectives: (1) to develop, evaluate and model mussel demographic rates; (2) to evaluate the physiological response of mussels exposed to chronic stress; (3) to develop culture techniques for at risk mussel species; and (4) to build decision support models. These data will assist the Service and partners to better protect and recover the listed mussels, and other rare species in the lower Flint River Basin. The scope of this project will be the lower Flint River Basin (LFRB) in southwest Georgia. The LFRB is located predominantly within the Fall Line Hills and Dougherty Plain districts of the Coastal Plain physiographic province. Streams flowing through the Fall Line Hills district are characterized by sandy-mud substrate and relatively high turbidity levels, whereas streams flowing through the Ocala Limestone formation contain greater amounts of coarse substrates and lower turbidity (Peterson et al in press). Ocala Limestone streams also generally receive substantial amounts of groundwater from the underlying Floridan aquifer and have higher temperatures during the winter. This project will study the response of individuals and populations of mussels to environmental stressors and compile existing information on at risk mussel populations to: (1) estimate the relations between mussel population demographics and environmental conditions; (2) evaluate the efficacy of chronic stress markers for monitoring mussel populations; and (3) develop techniques for propagating at risk mussels. This information, when combined into a decision support model will be essential to: � Identify the management actions that will have the greatest benefit to mussel populations at local (project specific actions) and watershed levels (such as the basin-wide guidelines). � Prioritize areas (basins, stream segments) for conservation and to improve Service recommendations provided during Endangered Species Act or Fish and Wildlife Coordination Act consultations. � Estimate the likely effects of anthropogenic changes (hydrologic alteration) on mussel populations. � Identify the key components for monitoring mussel populations. � Develop a means to formally incorporate monitoring data to improve adaptive management efforts.

Technical support for Adaptive Harvest Management for American black ducks	December 2010	Scientific management for American black ducks (Anas rubripes) has been hampered by a lack of understanding regarding factors affecting the dynamics of black duck populations. This has resulted in a lack of agreement among stakeholders as to the potential for arresting the decline of black duck stocks through management intervention, especially through harvest regulations. This work builds on previous work for the Principal Investigator, entitled, "Development of an Integrated, Adaptive Management Protocol for American Black Ducks" (RWO 50). In that work, the PI developed and evaluated several single-and multiple-population adaptive harvest management (AHM) models. Initially, a single-population model was developed based on the monograph by Conroy et.al. (2002), in which abundance of black ducks and mallards (Anas platyrhynchos) were parameterized by midwinter surveys. The AHM project extended these models to breeding surveys implemented by Canadian Wildlife Service starting in 1990, and developed both spatially-stratified and non-stratified models. Fish and Wildlife Service and Canadian Wildlife Service have now agreed to move forward with implementation of AHM for black ducks. Additional technical work is needed to support this implementation, and to address technical issues not completely resolved by the recently completed work order (RWO 85). Specific tasks to be addressed in the proposed project are: The objective of this work is to produce models that can be used to support AHM as an international harvest management strategy for American black ducks. Each of the tasks and deliverables below is essential to meet this objective. 1. Incorporate new integrated fixed-wing/helicopter BPOP estimates into Python models of black duck dynamics. 2. Incorporate historical, longer-term data from MWS surveys and US harvest surveys via Bayesian analyses, in which the latter would be used to build prior distributions. 3. Incorporate estimates from 1) and 2) into dynamic optimization tools (ASDP). 4. Investigate approaches using MCMC or other methods for updating model weights through monitoring.	None
A proposed approach for implementing a region-wide search for the ivory-billed woodpecker with the objective of estimating occupancy and related parameters	June 2010	The purpose of this document is to propose and facilitate a survey design for the Ivory-billed Woodpecker (Campephilus principalis) search effort that will: (1) allow estimation of occupancy, use, and detection probability for habitats at two spatial scales within its former range, (2) assess relationships between occupancy, use, and habitat characteristics at those scales, (3) allow the development of a population viability model that depends on patch occupancy instead of difficult-to-measure demographic parameters, and (4) be adaptive, allowing newly collected information to update the above models and search locations.

Review of Georgia reservoir fish monitoring data and sampling procedures	June 2024	The Wildlife Resources Division of the Georgia Department of Natural Resources (DNR) has regularly sampled fish populations across Georgia’s freshwater systems for over 30 years. The data collected are maintained in the Division’s Long-Term Fish Monitoring Database. Attributes recorded in the database include sampling event details (location and date), methods (gear and effort), and metrics on individual fish (e.g., species, length, weight). We are working with the Division’s Fisheries Section to identify research questions that can be addressed by the data and conduct analyses relevant to those questions. We will make determinations about the utility of the data for assessing status and trends of populations or fish communities, increasing monitoring efficiency, and designing focused monitoring or research efforts.

Evaluation of Contaminant Stressors to Endangered and At-Risk Freshwater Mussel Health in the Conasauga River Basin	May 2024	The Conasauga River, in southeast Tennessee and northwest Georgia, is a biodiversity hotspot for fishes and freshwater mussels. Some of these species are rare, at-risk, or listed under the federal Endangered Species Act. Additionally, two species of mussels have been characterized as extinct from the basin. We propose a collaborative multiyear research study to evaluate the threat of contaminants on freshwater mussels in the Conasauga River. This study will examine the use of sediment and <i>in situ</i> water exposures to non-point source pollutants to further understand toxicant effects on juvenile freshwater mussels. We intend to collect information that will help the U.S. Fish and Wildlife Service’s Georgia Ecological Services Field Office prioritize conservation or management actions to support freshwater mussels. Further, data collected on the effects of contaminants on mussel growth and survival could be used in population models to evaluate population-level effects in contaminated vs non-contaminated sites. More broadly, such results may improve understanding of the potential effects of non-point-source pollution on freshwater mussels.

Comparison of Largemouth-Bass reservoirs in GA.	August 2022	The overarching objective of this proposed project is to further assess variability in monitoring data for fish populations. For instance, we may be able to further explore quantifiable shifts in fish population metrics in response to ecological perturbations or management interventions. Thus, the project’s focus will be on data analytics and multi-agency collaboration. This project is intended to involve a partnership with one or more federal or state agencies in the southeastern U.S. Analyses focused on variability may help inform survey designs (e.g., reduce monitoring effort by eliminating sites or skipping years?), have implications for interpreting data produced by monitoring programs (e.g., trend detection), and be an important consideration for scenario forecasting (e.g., predicting potential frequency of extreme events).	We intend to collaborate with one or more partners conducting monitoring, research, or management of fishes in the southeastern U.S. This partnership will likely include working with the collaborator to identify and prioritize an information need along with an assessment of access to sufficient monitoring data. Model development will be initially guided by discussions with potential project partners in order to identify availability of fish population data (e.g., # of sampling sites and sampling years) as well as availability of covariate information or site-level characteristics (e.g., water clarity, temperature, sampling depth, spatial location). Of course, some details of model development and data analysis will be dependent on available data. However, we expect that a mixed-model framework will be conducive for asking questions about changes in spatial or temporal variation. This project will support the professional development of one or more graduate students, including the opportunity to report findings. The project will help build capacity in quantitative assessment and further support development of statistically sound long-term natural resource monitoring.
Updating population parameters of Sicklefin Redhorse with new data form the Hiawassee River Basin	August 2021	The Georgia Department of Natural Resources (GADNR) is engaged in collaborative efforts to monitor Sicklefin Redhorse (<i>Moxostoma</i>, undescribed) in north Georgia. We are adding new data from GADNR and attempting to estimate additional parameters.	Sicklefin Redhorse (<i>Moxostoma</i> sp.) is a native freshwater fish (undescribed species), whose range includes the Hiwassee River Basin in NC and GA, and the Little Tennessee River Basin in NC. The fish is rare within its range and is facing potential threats such as habitat degradation and migratory barriers. Little is currently known about the status and population dynamics of Sicklefin Redhorse, which could impede effective management. The Georgia Department of Natural Resources is engaged in collaborative efforts to monitor Sicklefin Redhorse in north Georgia. In addition, the Sicklefin Redhorse Conservation Committee (which is a partnership that consists of state agencies, federal agencies, NGOs, and power companies) is devoted to conservation and management of the species. The Georgia Cooperative Research Unit recently collaborated with the Sicklefin Redhorse Conservation Committee and researchers from University of Georgia to develop a population model estimating important parameters to evaluate the status of the Sicklefin Redhorse population in Brasstown Creek, GA using capture-mark-recapture data. More recent data will be included in an updated model to refine estimates of important population parameters, which may influence future monitoring or management decisions.
Identifying Pollinator Habitat Along Power Line Right of Ways in the Georgia Piedmont	September 2022	The Piedmont prairie is a biologically diverse grassland found in Georgia, hosting several obligate plant species and other plant species that allow pollinators, including the monarch butterfly, to complete their life cycle. This diversity is under threat due to habitat fragmentation caused by incompatible land uses, but powerline right-of-ways (ROWs) may provide an opportunity to conserve these grasslands and maintain some degree of habitat connectivity. Little is known about the occurrence and distribution of Piedmont prairies along powerline ROWs. Identifying these sites will assist managers in making decisions about resource allocation between management of existing prairie habitat and creating new habitat. The University of Georgia is conducting this work in collaboration with the Georgia Power Company and the Electric Power Research Institute. The research will contribute to basic understanding about distribution and abundance of Piedmont prairies within the powerline ROW network in Georgia. The research will also help managers decide on targets for pollinator habitat conservation.

Chinook salmon passage and recovery on the Willamette River	September 2024	Willamette River basin adult spring-run Chinook salmon (<i>Oncorhynchus tshawytscha</i>) are prevented from returning to their historic spawning grounds by large dams managed jointly by the U.S. Army Corps of Engineers (USACE), Bonneville Power Administration, and Bureau of Reclamation. In response, USACE and Oregon Department of Fish and Wildlife biologists initiated an adult transportation program in the 1990’s with an objective of facilitating natural spawning of these populations above the dams. Unfortunately, annual rates of pre-spawn mortality (PSM) in adult Chinook salmon transported upstream of dams are high (often >40%), and could limit the ability to establish a natural population of spring Chinook if not reduced. The progeny of these outplanted adults face similar downstream passage difficulties that is further complicated by very high parasitic infection rates (>90%) of a native copepod (<i>Salmincola californiensis</i>). The infections affect the ability of outmigrating juvenile to swim, withstand stressors, and survive in saltwater during their ocean transition. This is an integrated project whose ultimate goal is the safe passage of juvenile and adult spring-run Chinook salmon to assist in the recovery of this listed stock.	Stream fragmentation and water development are among the greatest threats facing Chinook Salmon in the Pacific Northwest.<br><br>Recovery of this iconic species will require the development of effective fish passage strategies to facilitate juvenile and adult passage to and from their historic spawning grounds.<br><br>This project is a collaboration of an interdisciplinary team of researchers and managers from USGS, USACE, Pacific Northwest National Laboratory, Oregon State University, and Oregon Department of Fish and Wildlife.<br><br>Water resource managers will be provided with the information needed to develop safe and efficient passage systems for juvenile and adult Chinook salmon.
Modeling and Optimization to Advance Decision-making for Trust and At-risk Species	March 2022	Since 2012, an adaptive management framework has been in place to guide harvest of horseshoe crabs in the Delaware Bay in a way that maximizes crab harvest while leaving in place sufficient foraging resources for shorebirds. However, estimates of crab abundance that inform the decision model are known to have biases, and the software that generates tables of optimal actions runs only on outdated, unsupported operating systems. Basing harvest management decisions on biased information compromises management performance, and outdated optimization software prevents the implementation of technical improvements. Addressing both shortcomings of the decision making framework will increase quality of harvest management decisions. The University of Georgia is conducting this work in collaboration with USGS and member agencies of the Atlantic States Marine Fisheries Commission (ASMFC). The research will result in improved estimates of state, model refinements, and a new optimization platform. Together, these components will provide annual recommendations of optimal harvest packages to be considered by members of the ASMFC.

Mitigating emerging disease impacts in fisheries: adaptive strategies to ensure a safe, healthy seafood supply	December 2021	A diverse team is organized at the University of Georgia to synthesize existing literature and for adaptive strategies for fisheries in the face of disease outbreaks.	Humans are expected to have increased demands for seafood. The health and population size of fish stocks are important to food production and security. There are needs for a systematic and comprehensive analysis and for new tools to address consequences and form adaptive strategies for fisheries in the face of disease outbreaks. For instance, in Georgia, shrimp fishing is important, but detrimentally affected by an ongoing epidemic of a parasitic ciliate called shrimp black gill. A diverse team is organized at the University of Georgia to synthesize existing literature, develop flexible modeling approaches for predicting and managing disease outbreaks in fisheries, and leverage efforts into a larger discipline-bridging proposal. A PhD student at the University of Georgia is being supported by this project. This interdisciplinary work aims to broaden the University’s capacity to lead in anticipating or responding to emerging diseases that threaten provision of safe and sustainable seafood (fishery and aquaculture).
Benefit-cost Analysis for the Threatened and Endangered Species Program of the Bureau of Land Management	January 2021	The Georgia Unit is partnering with applied economists at the University of Georgia in an attempt to quantify and monetize the resulting beneficial outputs stemming from a selection of BLM programs and evaluate the benefits of avoiding the listing of a species or the delisting of a previously listed species.	This project is a first step to focus on operational cost savings or other programmatic benefits derived from the BLM’s Threatened and Endangered Species program. Effort is focusing on a question of broad interest: “What are the benefits of proactive conservation?” The Georgia Unit is partnering with applied economists at the University of Georgia in an attempt to quantify and monetize the resulting beneficial outputs stemming from a selection of BLM programs and evaluate the benefits of avoiding the listing of a species or the delisting of a previously listed species. Project tasks include producing an annotated bibliography with a narrative discussion related to economics of endangered species and ESA programs and seeking additional federal case-study examples to document restrictions, expenditures, transaction costs, or benefits related to delisting or avoiding listing.
Statistical support for long-term natural resource monitoring	October 2023	This project provides statistical and technical assistance to the National Park Service’s Inventory and Monitoring Division, with a focus on developing interactive data dashboards for reviewing and analyzing long-term monitoring data for a variety of resources (including but not limited to water, vegetation, cave biota, and amphibians).	Throughout the world, monitoring surveys provide essential information for understanding, restoring, and managing populations. The National Park Service (NPS) Inventory and Monitoring (I&M) Program aims to understand status and trends in resource conditions and provide accessible information. The Georgia Unit is assisting NPS I&M with evaluation of sampling designs and pilot data as well as analytical and reporting approaches for monitoring data. This project supports development of statistically sound long-term natural resource monitoring, and will directly assist NPS consider monitoring objectives, data limitations, and potential predictors of interest. The project is currently looking to support a Post-doctoral Research Associate, at the University of Georgia, to collaboratively develop methods and tools for quality-control review; provide statistical and technical applications for analyzing or visualizing monitoring data; and interact with several partners across the southeast region.
Comparing recruitment estimation methods for age-1 Atlantic Sturgeon in the Altamaha River, GA from 2008-2020	August 2021	This project is comparing methods for estimating abundance of age-1 Atlantic Sturgeon in the Altamaha River, Georgia in an attempt to improve population estimates and gain insight into potential factors influencing recruitment.	The Atlantic Sturgeon (<i>Acipenser oxyrinchus oxyrinchus</i>) is an anadromous fish species that was once of great commercial importance in many of the coastal rivers of the eastern U.S. As a result of multiple centuries of overharvest and habitat degradation, this species is now listed as endangered over most of its range. Due to a complex life history, determining population size within a particular river is logistically difficult. Sampling river-resident juveniles is therefore a practical method for investigating long-term population trends. The project is being conducted by the University of Georgia and is funded by the National Marine Fisheries Service as well as the Georgia Department of Natural Resources and the Warnell School of Forestry and Natural Resources at UGA. Three abundance estimation methods, which will consider different components of the capture data including spatial information, environmental covariates, and varying effort, will be used to estimate age-1 abundance of Atlantic Sturgeon in the Altamaha River, Georgia. Comparing the precision of these methods will improve future population estimates as well as give insight into the abiotic factors affecting recruitment variability within Atlantic Sturgeon populations.
Assessing Actively Poached Galax Populations to Inform Restoration and Law Enforcement	December 2021	This project is a partnership with the National Parks Service, the Appalachian Highlands Monitoring Network, as well as the University of Georgia and USGS. This research will support decisions on galax management within the Blue Ridge Parkway, including law enforcement activity and identifying further research needs to assess the status of galax in the park.	The southern Appalachians are a hotspot of biodiversity and some local species may be being harvested to the point of overexploitation. <i>Galax urceolata</i> is harvested for sale and use in background foliage and floral decorations. In recent years, illegal harvest on the Blue Ridge Parkway has increased to a point that it may be contributing to population declines. There is a growing need to understand the scope of poaching in protected areas, and to study the impact of harvest on non-timber forest products. Assessment of the impact of harvest and other factors on galax abundance will help identify possible solutions to this issue. This project is a partnership with the National Parks Service, the Appalachian Highlands Monitoring Network, as well as the University of Georgia and USGS. This research will support decisions on galax management within the Blue Ridge Parkway, including law enforcement activity and identifying further research needs to assess the status of galax in the park.
Incorporating Structured Decision Making and Alternative Sources of Data into Management of White-tailed Deer in Georgia	June 2022	In Georgia, the management of deer populations across the state is challenging because of regional variation in landscapes, deer population status, property ownerships, and other factors. Sources of harvest data available to the state of Georgia primarily through self-reporting mechanisms are potentially usable for providing harvest management decision support, but these data sources have unknown biases. We will investigate the utility of these data sources under a structured decision making framework, which establishes the context for the types of data needed to support harvest decision making and their required degree of quality. This approach will help to identify analytical processes or ancillary data sources that protect the quality of decisions from influence of sampling and self-reporting biases. This work is being performed in a collaboration between the University of Georgia and the Georgia Department of Natural Resources. The research will result in recommendation of one or more candidate harvest decision support frameworks that address the goals of stakeholders and that identify priorities for the collection of data most useful for guiding management.

Improving and Field Testing Novel Methods to Estimate White-tailed Deer Density Using Camera Traps	September 2021	Reliable methods for estimating deer abundance and for monitoring temporal trends in density are important components of effective deer management. A cost-effective, camera-based survey method would be useful for assessing the effects of management practices on trends in density and recruitment rates. In Georgia, concerns exist about declining densities of deer and declining recruitment rates that have resulted from changes in land use and changes in the predator community. Customary camera-based survey approaches for estimating population quantities at the degree of accuracy and precision needed for decision making are cost-prohibitive. This study is a collaborative effort between the University of Georgia and Georgia Department of Natural Resources. This research will produce a cost-effective camera-based survey approach that is cost-effective to apply at large scales and is free of the estimation assumptions that encumbered previous approaches. Deer managers for the state of Georgia will be able to make population and habitat management decisions using more robust demographic information.	Reliable methods for estimating deer abundance and for monitoring temporal trends in density are important components of effective deer management. A cost-effective, camera-based survey method would be useful for assessing the effects of management practices on trends in density and recruitment rates. In Georgia, concerns exist about declining densities of deer and declining recruitment rates that have resulted from changes in land use and changes in the predator community. Customary camera-based survey approaches for estimating population quantities at the degree of accuracy and precision needed for decision making are cost-prohibitive. This study is a collaborative effort between the University of Georgia and Georgia Department of Natural Resources. This research will produce a cost-effective camera-based survey approach that is cost-effective to apply at large scales and is free of the estimation assumptions that encumbered previous approaches. Deer managers for the state of Georgia will be able to make population and habitat management decisions using more robust demographic information.
Restoration of a Relict Population of Gopher Tortoises Through Translocation of Waif Animals	April 2019	The gopher tortoise (Gopherus polyphemus) has declined over most of its range and is currently a candidate for listing under the U.S. Endangered Species Act. Active conservation management is being employed, including the translocation of “waif” tortoises (animals temporarily in human custody that cannot be returned to the point of origin in the wild) in some efforts to augment existing populations. The efficacy of translocating waif animals for the purpose of population augmentation is unknown, both with respect to the demographic performance of released tortoises and the health of the population into which they are released. This research, conducted at an isolated site on the periphery of the range, will provide needed information on the benefits and risks of translocating waif tortoises. This research was conducted in collaboration with the University of Georgia’s Savannah River Ecology Laboratory and the South Carolina Department of Natural Resources. This research will be used by conservation agencies and their partners to weigh the risks of using waif animals for reintroduction stock for the augmentation of existing populations.

Head-Starting as a Recovery Strategy for the Desert Tortoise	December 2021	The Mojave Desert tortoise (Gopherus agassizii) population, classified as Threatened under the U.S. Endangered Species Act, is in decline and in need of active management for population recovery. The rearing of neonate tortoises until they are more likely to survive (head-starting) is one strategy for population augmentation. Although head-starting has intuitive appeal as a conservation strategy, the strategy is expensive, and its success depends on how soon and how successfully head-started animals reproduce in the wild compared to wild-reared animals. While the husbandry phase of captive tortoises is well understood, the function and performance of head-started tortoises once released in the wild have not been evaluated. This research is conducted in collaboration with the University of Georgia’s Savannah River Ecology Laboratory, University of California-Davis, and National Park Service. This research will be used by conservation agencies and their partners to weigh trade-offs between the costs of head-starting against the expected benefit of head-starting to enhance tortoise population growth and persistence.

Impacts of Extreme High Tide Events on Sea Turtle Nesting on Georgia Barrier Islands	April 2018	Climate change and associated sea level rise is expected to lead to an increase in extreme high tide events and consequent storm surges, erosion, and coastal flooding on the Atlantic coast. Reproductive success of the loggerhead sea turtle (Caretta caretta), which is listed as Threatened under the U.S. Endangered Species Act, is dependent on the timing of emergence, nest siting, and nest laying activity, and these in turn are linked to dynamics of tidal cycles and storm events. Conservation of the loggerhead sea turtle requires an understanding of how nesting habitats and hatchling productivity will be affected by factors associated with climate change. Results from this work will help Georgia Department of Natural Resources and other management agencies understand the likely impact of extreme high tide events on sea turtle productivity and the necessary conservation measures needed to mitigate against adverse impacts. This research was conducted in collaboration with Georgia Department of Natural Resources and the University of Georgia. This work produced projections of the frequency of extreme high tide events, which served as inputs to models that predicted nest success in response to physiographic and habitat attributes of the nest. This research will be used by conservation agencies in Georgia and elsewhere to plan for mitigation and adaptation strategies for the turtle.

Hardwood Management in Open Pine Ecosystems on Sam D. Hamilton Noxubee National Wildlife Refuge	July 2018	Managers of the Sam D. Hamilton Noxubee National Wildlife Refuge are currently conducting hardwood management control to generate high quality foraging habitat for Red-cockaded Woodpeckers on two management units. Response by open pine-dependent avian species that are not the focus of this management is of interest to refuge managers. Habitat management on wildlife conservation areas, such as units of the National Wildlife Refuge System, is often oriented at single-species response. This research will help inform quantify carry-over benefits, if any, to non-target avian species in mixed pine-hardwood systems. This research was conducted in collaboration with the U.S. Fish and Wildlife Service, the University of Georgia, and USGS. This research will help the Refuge plan sampling strategies and provide analytical models for the evaluation of habitat management effects on non-target avian species.	Managers of the Sam D.

Completing a Double-Loop Learning Cycle in the Native Prairie Adaptive Management System	December 2019	Under the Native Prairie Adaptive Management (NPAM) program of the U.S. Fish and Wildlife Service, land managers in the National Wildlife Refuge System in Regions 3 and 6 receive annual habitat management guidance for the goal of restoring prairies to desired composition levels of native grasses and forbs. While this operational adaptive management program has successfully provided guidance through nine decision cycles, longstanding concern about the use of expert-elicited quantities in the predictive models has not abated among the managers and the developers of the program, and the concern has prompted a comprehensive “double-loop” evaluation of the framework elements. This research will produce models for decision guidance that conform more closely with the system responses observed to date, leading to better management performance. Examples of operational adaptive management systems are rare, and examples of double-loop learning are rarer still, so this research will provide a durable and transferable demonstration of this concept. This research is conducted in collaboration with the U.S. Fish and Wildlife Service, the University of Georgia, and USGS. The models supporting the decision framework were employed in time for the August 2019 decision cycle. Management recommendations provided to cooperators at that time reflected the improved decision guidance.

Technical Assistance to Georgia DNR for Nongame Bird Monitoring and Research	September 2021	The Wildlife Conservation Section of Georgia Department of Natural Resources Wildlife Resources Division, which has management authority for a diversity of animal and plant species within Georgia, needs (1) reliable population estimates of nesting Florida Sandhill Cranes (Grus canadensis pratensis) in Okefenokee National Wildlife Refuge and (2) reliable inferences on demographic parameters of Henslow’s Sparrow (Ammodramus henslowii). This work will provide survey design enhancements and analytical models to meet these needs. These two species are of conservation concern to the state, and Georgia DNR already invests heavily in monitoring and obtaining demographic data on them. Georgia DNR is an important cooperator with USGS, and this work addresses its concerns that its efforts could be better aligned with its objectives of understanding these populations. This work is being done in collaboration with Georgia Department of Natural Resources and the University of Georgia. The production of reliable biological information for these two species will help the state of Georgia better target their resources towards actions that conserve these species.

Forestry BMP for Sensitive Aquatic Species Southeastern US	August 2021	In the Southeastern United States, forestry is a major land use and an important component to the economy. Monitoring by state agencies has confirmed that generally, forestry Best Management Practices (BMP) are implemented at high rates (82% - 99%), but implementation varies by locale and BMP type. The distribution of aquatic at-risk species and their degree of imperilment also vary across the southern landscape. Some BMPs are effective in the protection of water quality, but information on the degree to which BMPs might support conservation of at-risk aquatic species is lacking. This information gap is especially acute in the southeastern US with its high degree of endemism and levels of imperilment for several species. Filling this critical information gap will provide a better understanding of the effectiveness of BMPs for protecting sensitive aquatic species and their habitat and will help to inform conservation measures.	During FY18, we conducted activities to clarify which Best Management Practices (BMP) are of interest to both forest managers and aquatic biologists and documented with sufficient spatial and temporal resolution to be useful in the modelling of aquatic species response. We have identified individuals within the forestry and aquatic conservation committees who will serve on an advisory board for the project. We have identified appropriate data sources and are in the process of quality assurance on a variety of point datasets of fish presence derived from museum and collection records.<br>In our initial discussions with these groups, Foresters have focused on activities to minimize the acute impact of harvest (e.g., sediment management zones) or forest roads (e.g., appropriate crossing designs). While stream biologists acknowledge the importance of these primarily sediment-focused measures, they also indicate that they sometimes consider other aspects of timber management, including rotation schedule, thinning, and fire suppression, to be BMPs due to their ability to affect water yield. Work to date on the project has been preparatory, and the modeling to evaluate which BMPs are offer conservation benefits to imperiled aquatic species in the region will continue in earnest in FY19.<br><br>

Estimating population size of Sicklefin Redhorse in the Hiwassee River system	June 2019	The Georgia Department of Natural Resources (GADNR) is engaged in collaborative efforts to monitor Sicklefin Redhorse (Moxostoma, undescribed) in north Georgia. We assisted the GADNR by developing a model to estimate population parameters, using combined data from fyke netting and PIT antenna arrays.	Sicklefin Redhorse (<i>Moxostoma</i> sp.) is a native freshwater fish (undescribed species), whose range includes the Hiwassee River Basin in NC and GA, and the Little Tennessee River Basin in NC. The fish is rare within its range and is facing potential threats such as habitat degradation and migratory barriers. Little is currently known about the status and population dynamics of Sicklefin Redhorse, which could impede effective management. The Georgia Department of Natural Resources is engaged in collaborative efforts to monitor Sicklefin Redhorse in north Georgia. In addition, the Sicklefin Redhorse Conservation Committee (which is a partnership that consists of state agencies, federal agencies, NGOs, and power companies) is devoted to conservation and management of the species. The Georgia Cooperative Research Unit recently collaborated with the Sicklefin Redhorse Conservation Committee and researchers from University of Georgia to develop a population model estimating important parameters to evaluate the status of the Sicklefin Redhorse population in Brasstown Creek, GA using capture-mark-recapture data. The model provided information such as survival probability, recruitment, and spawning population abundance. A future project is anticipated so that more recent data can be included in an updated model to refine estimates of important population parameters, which may influence future monitoring or management decisions.
Black Rail ecology to inform effective survey design and support population modeling	August 2021	The Black Rail is currently under review by the USFWS for protection under the Endangered Species Act. Black Rails have experienced population declines, breeding range retractions, and reductions in number of breeding locations within its core range. In the Southeast U.S., most remnant populations occur in high elevation marshes near or along the Atlantic and Gulf coasts, a habitat particularly vulnerable to development pressure, altered hydrological patterns, Phragmites and fire ant invasion, sea-level rise, and incompatible management practices. Research priorities identified by consensus of government and non-government partners include (1) extensive surveys of appropriate habitat using a standardized protocol specific to Black Rails, and (2) basic life history research including nest success and factors limiting productivity, and habitat requirements of breeding, transient, and wintering birds.<br><br>This project addresses multiple research and technical assistance objectives to address the above priorities: Employ automated telemetry on a known population of Black Rails (St. Johns National Wildlife Refuge) to (1) estimate Black Rail vital rates; (2) estimate breeding and wintering home ranges and habitat selection; and (3) quantify diel patterns of activity. Collect biological samples to evaluate (4) migratory origins of wintering Black Rails using stable isotopes. Additionally, (5) devise, implement, and evaluate modifications of existing marsh bird protocols to improve the applicability to Black Rails. Finally, (6) coordinate USFWS-funded comprehensive marsh bird surveys on southeast national wildlife refuges.	Black rails (Laterallus jamaicensis) have experienced population declines, breeding range retractions, and reductions in number of breeding locations within its core range, and the species is currently under review by the USFWS for protection under the Endangered Species Act. With the species facing an array of threats, research priorities identified by consensus of government and non-government partners include (1) extensive surveys of appropriate habitat using a standardized protocol specific to black rails, and (2) basic life history research including nest success and factors limiting productivity, and habitat requirements of breeding, transient, and wintering birds. This work will directly inform the status assessment for the black rail’s candidacy for protection under the ESA. The work will also address information needs identified by coalitions of conservation groups and management agencies. This work is being conducted by a collaboration of partners in USGS, U.S. Fish and Wildlife Service, and the University of Georgia. This project includes multiple research and technical assistance components to address the research priorities identified by conservation partners. The work will produce estimates of vital rate parameters usable in predictive population models supporting decision making, and the work will provide modifications of existing marsh bird protocols to better monitor this secretive species.
Assessment of Endocrine Disrupting Chemicals in the Upper Conasauga River, Georgia	September 2018	The project will evaluate the prevalence of endocrine-disrupting chemicals along a disturbance gradient in the upper Conasauga River and relate that prevalence to intersex in fish.	During FY18, lab experiments in which Japanese medaka and tricolor shiners were exposed to endocrine disrupting chemicals were completed successfully. Analysis of metabolites in fish liver and mucous also were completed, but statistical analysis remain to be completed. The final analysis will be determined in consultation with quantitative biologists at EPA and USGS and will evaluate relationships between environmental variable and oocyte numbers at the individual-fish level. Manuscripts for the controlled lab experiment and UCR intersex model are nearing completion and are expected to be submitted for peer review in fall 2018. Preliminary qualitative results have been presented at a variety of international/national/regional/state scientific meetings including the American Fisheries Society (AFS), the Society of Environmental Toxicology and Chemistry, Southern Division - AFS, and Georgia Chapter of AFS.
Impacts of Rabbit Hunting on Northern Bobwhite Demographics and Behavior	August 2021	Management of early successional habitat for northern bobwhites often provides habitat for other species, such as rabbits, with similar habitat preferences. This positive by-product creates additional opportunities for those who participate in small-game hunting. However, the concurrent pursuit of two species with similar habitat requirements may create conflicts among hunters or affect the demography or behavior of one or both of the species. Rabbit hunting, in particular, has the potential to disrupt bobwhite movements and behavior given the nature of pursuit involving large hunting parties and packing dogs. This disruption may subsequently affect bobwhite survival and/or bobwhite hunter satisfaction. This study focuses on effects of hunting at one Georgia DNR Wildlife Management Area in which activities of the two types of hunters are separated in time. Specifically, the study investigates whether rabbit hunting activity disrupts bobwhite behavior sufficiently to impact bird demography and consequently bobwhite hunter satisfaction.	Management of early successional habitat for northern bobwhites (Colinus virginianus) may provide as a byproduct habitat suitable for other species, such as rabbits (Silvilagus floridanus). Although this association creates additional sport hunting opportunities on the same site, concurrent pursuit of harvest objectives for two co-occurring species may create conflicts among hunters or affect demography or behavior of one or both species. Wildlife management agencies seek to increase opportunities for hunting on public areas, and strategies that appear to provide added opportunity for the same management effort are highly attractive to agencies. However, such strategies can have deleterious consequences if hunting activities directed at one species disrupts populations of the other species, ultimately leading to decreased satisfaction among hunters of that species. This research is conducted in collaboration with Georgia Department of Natural Resources and the University of Georgia. Research results will inform the Georgia Department of Natural Resources on costs – in terms of population performance and hunter satisfaction – for the perceived benefits of coincidental habitat and harvest management for two co-occurring species.
Environmental Stressors and Priority Plant Communities on Jekyll Island, Georgia	May 2020	Jekyll Island is a Georgia barrier island that supports developed tourism amenities and a residential community, but is also a state park that is committed to conserving and managing most of the island's area as natural habitat. Natural areas on Jekyll Island are facing a multitude of environmental stresses, most of whose root causes are anthropogenic. Sea level rise, climate change, altered surface and groundwater hydrology, fire suppression, invasive species, land development, and altered wildlife abundances can all affect the dynamics of vegetation communities. Many of Jekyll Island’s vegetation communities are locally or globally rare, unique to barrier islands, and highly regarded for their aesthetic and recreational values, all of which create a strong impetus for conserving the integrity of these vegetation communities and ecosystems. However, formulating natural areas management strategies is a complex challenge because of the simultaneous multiple stressors that are impacting plant communities, and the diverse range of ecological and social objectives – from biodiversity conservation and climate resilience, to tourism amenities and educational opportunities – that the Jekyll Island Authority’s mission seeks to balance. To surmount these complexities, this project combines three suites of scientific studies to (1) investigate the effects of multiple stressors on vegetation structure and dynamics in three high-priority plant communities, (2) integrate field and existing data on expected management outcomes into a decision support framework, and (3) evaluate stakeholder attitudes toward management options. This approach will deliver relevant, novel ecological information on the consequences of ecological stressors on high-priority natural areas, contextualized in terms of management options, in order to facilitate the Jekyll Island Authority in conservation planning. The findings delivered from the social research component will allow JIA managers to evaluate the potential tradeoffs, synergies, and leverage points between ecological conservation strategies and the values held by diverse stakeholders.	Jekyll Island is a Georgia barrier island that supports developed tourism amenities and a residential community, but it is also a state park that is committed to conserving and managing most of the island's area as natural habitat. Formulating natural areas management strategies is a complex challenge because of the simultaneous multiple stressors that are impacting plant communities, and the diverse range of ecological and social objectives – from biodiversity conservation and climate resilience, to tourism amenities and educational opportunities – that the Jekyll Island Authority’s mission seeks to balance. Jekyll Island is a prototypical example of a place that is vulnerable to both environmental stressors and the direct human stressor of being “loved to death.” This work will have relevance to the management of other barrier islands faced with similar threats. Partners in this work are USGS, the University of Georgia, and the Jekyll Island Authority. This work is expected to deliver relevant, novel ecological information on the consequences of ecological stressors on high-priority natural areas, contextualized in terms of management options, to facilitate the Jekyll Island Authority in conservation planning.
Adaptive Management of Federal Investments to Great Lakes Restoration Activities	September 2021	The Great Lakes Restoration Initiative (GLRI) is a large federal program aimed at protecting and restoring the largest system of surface freshwater in the world. Among its project portfolios are efforts to prioritize terrestrial conservation projects to increase habitat connectivity for species of conservation importance to GLRI partners. Anthropogenic land uses can reduce native wildlife species’ ability to move through landscapes, potentially obstructing the movement of non-volant species to climate refuges to the north. An area of focus of the GLRI is the support of decisions aimed at restoring and conserving areas that link habitats across the complex of federal-owned lands in the ecoregion. The principal scientific partners in this work are USGS and the University of Georgia, and client partners consist of federal agencies involved in the GLRI. This work will produce analyses of landscape connectivity under alternative future scenarios and will quantify local-level contributions to regional-scale connectivity. This granular information will aid decision makers charged with choosing conservation acquisitions and actions aimed at maintaining high levels of connectivity in the face of uncertain future landscapes.

Accelerating Conservation of At-Risk Species in the Longleaf System	June 2022	The Southeast Region of the U.S. Fish and Wildlife Service is working actively with state wildlife agencies and other partners, through the Southeastern Association of Fish and Wildlife Agencies to assess the status of >300 species awaiting reviews for listing decision and to implement conservation for these species on public and private lands. The longleaf pine ecological system supports a number of priority at-risk species, including the gopher tortoise, striped newt, gopher frog, southern hognose snake, and Florida pine snake. Major science needs are to analyze and integrate new information from status surveys for this group of species and to identify those conservation actions to improve the status of these species. By involving partner groups in this work, this project will synthesize data for these priority species and will develop models that predict population viability as a consequence of predicted exogenous threats (e.g., climate change and land use conversion) and conservation actions in space and time to mitigate those threats. These products will be delivered in form that facilitates a future formal decision analysis in which tradeoffs in alternative conservation actions may be explored.	The Southeast Region of the U.S. Fish and Wildlife Service is working actively with state wildlife agencies and other partners to assess the status of >300 species awaiting reviews for listing decision and to implement conservation for these species on public and private lands. The longleaf pine (Pinus palustris) ecosystem supports several species of priority at-risk species, including the gopher tortoise (Gopherus polyphemus), striped newt (Notophthalmus perstriatus), gopher frog (Rana capito), southern hognose snake (Heterodon simus), and Florida pine snake (Pituophis melanoleucus mugitus); for these species, there has been no comprehensive effort to synthesize information and identify knowledge gaps for their conservation. Conservation agencies face an immense workload in assessing the status of numerous species and formulating conservation actions in response. By taking a comprehensive view of species within an ecosystem, the expectation is that efficiencies for planning conservation action will emerge, compared to a piece-by-piece approach. This work relies on a collaboration between USGS, U.S. Fish and Wildlife Service, the University of Georgia, and several state, federal, and NGO partners. By involving partner groups in this work, the project is expected to synthesize data for the five priority species above and to develop models that predict population viability as a consequence of predicted exogenous threats (e.g., climate change and land use conversion) and conservation actions in space and time to mitigate those threats. These products will be delivered in a form that facilitates a future formal decision analysis in which tradeoffs in alternative conservation actions may be explored.
Assess Field- and Landscape-Level Effects of NRCS Conservation Practices on Gopher Tortoise Habitat	August 2020	The Working Lands for Wildlife (WLFW) program of the Natural Resources Conservation Service provides financial incentives for private landowners to manage their lands in ways that enhance habitat suitability for wildlife species of conservation concern, including the gopher tortoise. This project has two purposes: (1) assess how well WLFW has delivered conservation benefit on enrolled properties with respect to habitat and population metrics, and (2) develop enhancements in population assessment technology to more sensitively gauge how tortoise populations respond to conservation actions in short time frames.	The NRCS Working Lands for Wildlife (WLFW) program for the gopher tortoise (Gopherus polyphemus) was initiated in 2013, with enrollments in the states of Alabama, Florida, and Georgia. The program provides incentive payments to private landowners for implementing habitat management practices believed to promote sustainability of tortoise populations, but there has been no assessment of whether WLFW is achieving its goals and no identification of challenges in its implementation. A component of this research addresses enhancements to the field survey protocol used across the range of the tortoise; thus the management community will have a better tool to quantify tortoise populations. The research will also help determine if the allocation of public dollars to incentivize private landowners is having the intended effect and will further clarify how tortoise populations respond to habitat management actions across the range. Partners from USGS, NRCS, the University of Georgia, and the Joseph W. Jones Ecological Research Center are collaborating on this project. The implementation of an improved survey tool will provide more precision to management decision making. The work is also expected to inform NRCS about the effectiveness of the WLFW program in meeting habitat objectives and to identify attributes (local to landscape scale) that contribute to or impinge on the meeting of objectives.
Demographic Estimation and Conservation Modeling for the Loggerhead Sea Turtle	June 2020	Successful recovery of the threatened loggerhead sea turtle will hinge on decisions about where to invest limited resources into conservation actions, and these decisions will be informed by predictions of population response to each action. This study focuses on the development of decision or scenario planning models for the northern recovery unit of the turtle. We will first construct a demographic model by integrating data from various sources, including genetic mark-recapture data, nest counts, and in-water monitoring data. Next, we will outfit this model as a scenario/decision analysis tool and simulate the model to product output of use to managers. The main purpose of the model is to help state agency resource managers in the northern recovery unit discern the relative efficacy of actions under their control, to assess the relative contributions of stressors so that broad scope conservation strategies may be devised, and to identify key uncertainties in sea turtle demography to which targeted information gathering would yield more effective conservation delivery.	Decision-making aimed at recovering the loggerhead sea turtle (Caretta caretta) from threatened status is dependent on models that evaluate population vulnerability to an array of potential threats and that assess trade-offs of alternative conservation actions. Crucial uncertainties in population mechanisms exist, and demographic models can be used to identify those uncertainties to which targeted information gathering would yield more effective conservation delivery. Conservation management for loggerhead sea turtles is uncertain because key mechanisms and components of the population are unknown, and no framework exists to evaluate trade-offs of alternative actions in the face of this uncertainty. This work will provide the needed framework to advance conservation for the turtle, and it will provide a blueprint for model development and decision analysis for related conservation problems hampered by uncertainty. This work is a collaboration between USGS, the University of Georgia, and Georgia Department of Natural Resources. This work will result in a population model that integrates multiple sources of data including genetic mark-recapture, nest counts, and in-water surveys, and it will be outfit as a scenario/decision analysis tool for generating demographic output of use to managers. Among possible scenarios investigated are those that trade off one form of management for another if total resources for conservation are capped.
Statistical Support for NPS Southeast Region I&M Networks	July 2019	We are helping the NPS develop sampling designs and providing guidance for statistical analysis for data collected from long-term monitoring protocols by multiple Inventory & Monitoring Networks within the Southeast Region.	The National Park Service (NPS) Inventory and Monitoring (I&M) Program was introduced into more than 200 parks, where the NPS is charged with developing monitoring protocols for vital signs. To meet this important charge, the NPS, the Georgia Unit, and the University of Georgia partnered to develop objectives and statistical protocols for NPS monitoring programs within the Southeast Region. Several analyses of pilot survey data for amphibians, reptiles, and water quality were completed and informed development of I&M Standard Operating Procedures. This project completed a PhD-level Research Professional IV and led to an ongoing partnership with the NPS.
Develop Adaptive Management Framework for Robust Redhorse	November 2021	Structured decision making and scenario forecasting are being used in collaboration with several stakeholders to evaluate alternative conservation strategies for Robust Redhorse.	Robust Redhorse (<i>Moxostoma robustum</i>) is a native freshwater fish species, which inhabits a few river systems on the Atlantic slope of the southeastern U.S., and is considered imperiled. The species faces threats such as sedimentation and migration barriers created by hydropower dams. Some evidence suggests a potential population decline in recent years. A diverse group of stakeholders exists for supporting conservation efforts for Robust Redhorse. The Georgia Unit has been collaborating with the Robust Redhorse Conservation Committee (a partnership that includes federal agencies, state agencies, and utility companies) to develop an adaptive management framework to help stakeholders make informed management decisions. This project is helping to support a PhD student in the Interdisciplinary Conservation program at the University of Georgia. The objectives of the project include assessing current population status for each Robust Redhorse ecologically significant unit (ESU) and conducting scenario forecasts for each ESU to investigate population viability under different conservation strategies. The results from the forecasting models will then help decision makers identify preferable management options.
Assessment of Trout Management in Georgia	December 2019	We conducted a collaborative assessment to help GA DNR update or formulate a trout management strategy that will satisfy a plurality of GA’s trout anglers and be relatively robust to identified critical uncertainties. The overarching goal for this project is to increase both the amount and usability of socioecological information available to managers when making fisheries management decisions.	The northern part of Georgia is home to the native Brook Trout, but Brown Trout and Rainbow Trout are now considered to be naturalized in the state. In the early 2000s, a comprehensive management program (i.e., the “Georgia Trout Management Plan”) was developed around five major categories: 1) Trout Habitat Conservation; 2) Wild Trout Management; 3) Management of Hatchery Supported Waters; 4) Hatchery Production Program; and 5) Access and Angler Use Issues. The efficacy of this plan is a question of immediate interest to fishery managers at GA Department of Natural Resources (DNR). This project is a collaboration of the Fisheries Section of GA DNR, the University of Georgia, and the Georgia Unit. A stakeholder survey was completed in 2017. A corresponding student-led paper, which included an importance-satisfaction analysis of catch and noncatch attributes, was published in 2019 in the North American Journal of Fisheries Management. Two MS students have completed degree requirements. Local, regional, and national presentations have been provided along with several interactions with GA DNR to report findings in an effort to increase socioecological information available to managers when making fisheries management decisions, such as choosing among potential future stocking scenarios.
Integrating Metapopulation Ecology and Landscape Ecology for Improved Population Viability Analysis and Conservation Decision-Making	December 2017	Provide assistance with population viability analysis related to recovery planning for the federally-threatened Chiricahua leopard frog in Southern Arizona.	Some populations exist as fragmented subpopulations linked by dispersal. Metapopulation theory is applicable when a species occurs in a set of habitat patches within a landscape dominated by unsuitable habitat. Effective management relies on understanding factors affecting population dynamics. Objectives of this project include improving linkages between metapopulation and landscape ecology by applying spatially-explicit metapopulation models and providing assistance with population viability analysis related to recovery planning for the federally-threatened Chiricahua leopard frog in Southern Arizona. This research was conducted in collaboration with the USGS Amphibian Research and Monitoring Initiative.
Develop an Adaptive Management Framework to Reduce the Impact of Invasive Phragmites in the Great Lakes Basin	September 2021	This project will develop decision support tools for Phragmites management in the Great Lakes Basin. This effort will develop dynamic system models and decision support tools for Phragmites management that are informed by on-the-ground data. The new integrated approach will build on existing successful programs and resources (e.g., the Great Lakes Phragmites Collaborative (GLPC), structured decision making at the local land-unit scale, Best Management Practices (BMP) guidelines), develop much needed new components (e.g., standardized scalable monitoring protocol, centralized data management system, larger scale state/transition models, expanded BMP toolkit), and put in place a strategic information stream to support decision makers. Development of the integrated approach will need to be a multi-institution effort to both take advantage of existing investments and maximize basin-wide participation and investment by resource managers. Success of this project will result in a framework for using adaptive management to manage Phragmites on the patch and landscape scale.	Wetland invasion by Phragmites australis (common reed) in the Great Lakes coastal zone is a significant ecosystem and economic threat recognized by the public, NGOs, and governmental agencies at all levels. Although a tremendous amount of time and energy has been invested in invasive Phragmites management and control, the plant continues to be a regional threat (estimated at over 24,000 ha in 2010). Best approaches for the control of Phragmites are uncertain, and current management attempts are disjointed and have not been informative to other efforts. This project will provide a framework in which results from management actions across the region can be synthesized and converted into knowledge useful for further rounds of decision making. This work involves a scientific collaboration among three principal partners – the USGS, University of Georgia, and the Great Lakes Commission – and voluntary participation in the program occurs across a diversity of landowners including federal, state, and local government organizations, NGOs, and private individuals. The research has led to models, monitoring methods, and a decision support infrastructure that has successfully been implemented as an adaptive management system, the Phragmites Adaptive Management Framework (PAMF). Participants enrolled in PAMF receive management guidance for invaded sites, and they contribute data to the program that are informative for adaptive refinements of the system models.
Uncertainty and the Entanglement of Habitat Loss and Fragmentation Effects in the Management of Northern Bobwhites and Eastern Meadowlarks	February 2016	This project evaluates threats to important grassland bird habitats of the Gulf Coast Prairie resulting through oil and gas development, changes in land ownership patterns, and invasive species. We will build models that project results of these drivers under future economic scenarios and that predict the consequences of management alternatives intended to ameliorate these drivers. We will also identify the drivers of habitat fragmentation so that actions can be designed to minimize threats to high-risk areas.	None
An Adaptive Landscape Planning and Decision Framework for Gopher Tortoise (Gopherus polyphemus) Conservation	June 2018	Our project goal is to develop a decision support system for the iterative selection of conservation actions that leads to a viable landscape supporting the statewide tortoise population and associated species and communities of interest. We will approach this goal by using principles of structured decision making, in which the decision maker, Georgia Department of Natural Resources (DNR), is directly involved in the articulation of objectives, the definition of alternative actions, and the development of predictive models to evaluate consequences of different actions. Key uncertainties that make the decision difficult will be identified with DNR and incorporated into the decision making framework. This work will result in an integrated system of databases, computer algorithms, and monitoring designs that provides a mostly automated process for decision making under uncertainty and for acquiring information to reduce uncertainty.	The rangewide decline of populations of gopher tortoise (Gopherus polyphemus) led to its designation by the U.S. Fish and Wildlife Service as “warranted but precluded” for listing in the eastern portion of the species range. The state of Georgia has undertaken a concerted effort to conserve the tortoise, associated species, and isolated communities of concern within its borders. A decision to list the gopher tortoise across its range is expected to incur significant costs and burdens to the citizens of Georgia; therefore, the state of Georgia is motivated to preclude its listing by investing in science-based conservation efforts. Although the state has an array of management options available, including purchase of lands, establishment of conservation easements, and providing habitat management incentives to landowners, it lacks an objective means to evaluate benefits and tradeoffs among them under uncertainties about biological responses and future patterns of land use and climate change. The main client/partner of this project was the Georgia Department of Natural Resources (DNR), and other partners involved in this effort included the USDI Southeast Climate Adaptation Science Center, the University of Georgia, the Joseph W. Jones Ecological Research Center, and USGS. The work resulted in gopher tortoise population models and a decision framework that identifies sets of contiguous land parcels that maximize attributes pertaining to tortoise population viability. Georgia DNR may use this model to evaluate alternative land protection strategies to select those that efficiently meet conservation goals.
Validating Gopher Tortoise Habitat and Population Predictions for Georgia	December 2016	This project seeks the collection of fine-scale habitat data at sites that are occupied by gopher tortoises and at reference sites where tortoises are not found to assess performance of current habitat prediction models and to investigate their improvement through the use of other spatial data products. We also explore whether habitat conditions and extent predict gopher tortoise population size, and whether different forest management practices are predictive of those conditions.
Landscape Level Population Modeling as a Decision Support Tool for the Lesser Prairie-Chicken	September 2017	Under this project, we use spatially explicit population models to characterize the viability of the lesser prairie-chicken (Tympanuchus pallidicinctus) under various future conservation scenarios. This modeling effort will provide the prediction of future conditions for the species following the U.S. Fish and Wildlife Service’s Species Status Assessment framework to support future decisions under the Endangered Species Act (ESA) related to drafting recovery criteria, proposing designation of critical habitat, and implementing a range of conservation efforts.

Transactions of the American Fisheries Society 145:786-794. \| Abstract \| Download	June 2016	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.

Transactions of the American Fisheries Society 146:584-593. [Featured Article] \| Abstract	April 2017	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.

Natural Resource Modeling 28(3):348-376. \| Abstract	August 2015	The proliferation of double-crested cormorants (DCCOs) in North America has raised concerns over their potential negative impacts on game, cultured and forage fishes, island and terrestrial resources, and other colonial water birds, leading to increased demands from angler communities and aquaculturists to reduce their abundance. We developed a predictive model representing bird–fish interactions to help inform an adaptive management process for the control of DCCOs in multiple colonies in Michigan. Comparisons of model predictions with empirical data suggested that our relatively simple model was able to accurately reconstruct DCCO population dynamics during a period of intensive control in the past. Although parameterization of several model components was based on expert opinion or data for related species, we were able to discriminate among alternative parameterizations of demographic processes, especially site fidelity, based on comparisons of model predictions with observations of annual changes in DCCO numbers under management measures implemented from 2004 to 2012. We also identified remaining critical uncertainties in the spatial distribution of affected fish populations relative to the size of DCCO feeding areas, which could be used to prioritize future research and monitoring needs. Using this model, our forecasts suggested that continuation of existing control efforts would be sufficient to achieve long-term DCCO control targets in Michigan. Our model forecasts also suggested that DCCO control may be necessary to achieve management goals for some valued fisheries in Michigan, which were shown to have been impacted by DCCO predation. Finally, our simple DCCO–fish dynamics model could be extended by including more complex assumptions about DCCO and fish population dynamics and can be adopted for other DCCO management programs in North America or elsewhere.

North American Journal of Fisheries Management 41:115-129. doi:10.1002/nafm.10540 \| Abstract	February 2021	Anglers face constraints that influence participation and dropout rates. Some recreational anglers may be able to negotiate constraints by altering the timing or frequency of participation, acquiring new skills, or modifying non-recreational aspects such as family or work responsibilities. We consider data collected via a mail survey from Georgia-resident trout license holders to identify both perceived constraints and strategies used to negotiate them. To capture variation among anglers, survey responses were grouped by level of angler specialization using K-means cluster analysis, which resulted in a three-cluster solution of most, moderate, and least specialized anglers. Analysis of variance (ANOVA) tests were used to detect potential differences among the three specialization clusters. Tests revealed the least specialized anglers experienced constraints more frequently (mean=1.74 on a 4-point scale) than the most (1.55) or moderately (1.64) specialized anglers. Likewise, lease specialized anglers negotiated constraints (mean=2.81 on a 5-point scale) less frequently than the most (3.00) or moderately (2.75) specialized anglers. The least specialized anglers used negotiation strategies involving overcoming perceived lack of skill more frequently than their counterparts. The most commonly experienced constraints overall were lack of time due to work or family obligations and distance of Georgia’s trout waters from home. The most frequently used negotiation strategies overall were “learn to enjoy being outside and stress less about catching fish” (mean=3.86/5) and “encourage family or friends to go fishing with me” (mean=3.61/5). This research benefits fishery managers by providing a method of identifying angling groups that perceive more constraints and are less likely to overcome these constraints through constraint negotiation strategies. With this information, managers may choose to tailor efforts towards reducing constraints for angling groups that have low participation and may drop out of the activity all together.

Marine Policy 50:46-52. \| Abstract	May 2014	Small-scale fisheries have historically been marginalized in management and policy investments, and they often remain under-reported in national economic and fisheries statistics. Even so, small-scale fisheries are not entirely buffered from the impacts of globalization, such as the introduction and expansion of markets. This study measures the long-term impact of market-access on a coastal fishery on Nicaragua’s remote Atlantic Coast from approximately the time when fishermen had access to stable and predictable local markets until the present, when the region has been transformed by road connection. In the last four years, fisheries trade has expanded as road connection has facilitated export to distant markets. We used fishery-independent surveys to measure changes in indicators of fish-community status such as length-frequency, mean trophic level, and relative biomass. We also evaluated species-level changes in relative biomass of common snook Centropomus undecimalis and gafftopsail catfish Bagre marinus since these species are the most economically valuable and likely account for the most fish biomass in the system. Using historical records, reports, current observations and interviews, we assess changes in indicators of fishing intensity and market access over the past 17 years. From 1994 to 2011, community and species-specific metrics of the lagoon fishery declined significantly across all indicators. The potential social and economic outcomes of the decline in the fishery are far-reaching for the region, because this tropical fishery comprises the main source of protein and income for residents of twelve indigenous and Afro-descendent communities.

Human Dimensions of Wildlife. https://doi.org/10.1080/10871209.2020.1794082 \| Abstract	July 2020	Recent trends in outdoor recreation in the United States show declining participation in consumptive outdoor activities such as hunting and fishing, primarily because of a decline in per capita participation among certain ethnic groups, largely due to structural change in demography. 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.

Lessons Learned in Applying Decision Analysis to Natural Resources Management for High Stakes Issues Surrounded by Uncertainty. Decision Analysis 20: 326-342. \| Abstract	December 2023	Management agencies are tasked with difficult decisions for conservation and management of natural resources. These decisions are difficult because of ecological and social uncertainties, the potential for multiple decision makers from multiple jurisdictions, and the need to account for the diverse values of stakeholders. Decision analysis provides a needed framework for accounting for these difficulties when making conservation and management decisions. We discuss the benefits of the application of decision analysis for these types of issues and provide insights from three case studies from the Laurentian Great Lakes. These case studies describe applications of decision analysis for decisions within an agency (management of double-crested cormorant), among agencies (response to invasive grass carp), and among agencies and stakeholders (sustainable fisheries harvest management). These case studies provide insight into the ways that decision analysis can be useful for conservation and management of natural resources, but we also highlight future needs for decision making for these resources. In particular, applications of decision analysis for conservation and management would benefit from enhanced integration of both ecological and social science, inclusion of a broader base of stakeholders, and partnering with Indigenous peoples to better include traditional knowledge in these important decisions.

Southeastern Naturalist 13:(2):237-260. \| Abstract	May 2014	The dominant fish species within impounded coastal wetlands in the southeastern United States may be different from the species that dominate natural marshes. We tested the hypothesis that resident fish assemblages inhabiting impounded coastal wetlands in South Carolina would differ from resident assemblages in natural marshes of the southeastern United States. We used rarefied species richness, Shannon’s H’ diversity, J’ evenness,used Morisita’s Index of Similarity and the Percent Similarity Index to compare resident fish assemblages from two three years of impoundments fish samples to 12 open-marsh resident fish assemblages from previously published studies in North and South Carolina. Fish assemblages in impoundments were sampled with rotenone, and assemblages in natural marsh habitat were sampled with rotenone and seines. Comparisons yielding an index similarity index ≥ 0.50 were deemed moderately similar and those with an index ≥ 0.75 were deemed very similar. Fifty-three percent of the among-impoundment comparisons (Morisita’s Index) were at least moderately similar, whereas 67% of impoundment-natural marsh comparisons were moderately similar. The best-fitting model for describing the observed similarity indicesMorisita’s Indices contained only a difference in tidal influence. A difference in tidal influence between the compared assemblages caused a 63% decrease in the index of similarity. Species richness and diversity were greater in impoundments than natural marshes, but evenness was similar between habitat types. Our results support the hypothesis that resident fish assemblages in impounded wetlands and natural marshes are different, and in our system, a lack of tidal influence drives this difference.

Journal of Fish and Wildlife Management 5(1):70-86. \| Abstract	June 2014	In coastal South Carolina, many wetlands are impounded and managed as migratory waterfowl habitat. Impoundment effects on fish production and habitat quality largely are unknown. We used the size frequency method to estimate summer production of fish guilds in three impoundments along the Combahee River, South Carolina. We predicted that guild-specific production would vary with impoundment salinity, which ranged from three to 21 psu. We expected greatest marine migrant production in the impoundment with the highest salinity regime and greatest freshwater migrant and freshwater straggler production in the impoundment with the lowest salinity regime. Finally, we expected that estuarine species would be highly productive in all study impoundments, as these species can reproduce within these structures. We found that guild-specific productivity varied both among years and among impoundments, generally following salinity gradients, though to a lesser extent than expected. Our guild-specific estimates of fish productivity fell on the low end of the range of previously published estuarine fish production estimates. Additionally, we observed large mortality events in the study impoundments each summer. The results of our study indicate that during the summer, the study impoundments provided poor quality fish habitat to all guilds.

Adaptive management is a scientific approach to management that explicitly deals with this uncertainty. It involves predicting management outcomes, collecting data to test those predictions (monitoring), revising the predictions and adapting the management strategy to reflect the new knowledge. In this session, we introduce adaptive management and describe three projects where this tool is applied to aquatic resources.

Transactions of the American Fisheries Society \| Abstract	September 2009	Current approaches to assessing the potential effects of river regulation and water use on stream fish communities are based on physical habitat simulation and are not feasible for estimating these effects over large spatial scales. We developed a channel classification for streams in the lower Flint River basin, Georgia, based on gross channel morphology and geology and evaluated its usefulness at 23 study sites representing the four channel types in the basin. Our channel classification separated stream channel types based on dominant geology (upland residuum versus Ocala limestone) and channel form (confined versus unconfined). Fish were sampled and habitat measured at the study sites in spring, summer, and winter from 2001 to 2004, a period that included some of the lowest and highest seasonal flows ever recorded. The channel types differed with respect to diurnal variability in temperature and dissolved oxygen concentration as well as habitat characteristics (substrate, large wood). Statistical habitat modeling indicated that channel unit (e.g., pool, riffle) availability could be predicted accurately for each channel type using streamflow, with errors rates that averaged 0.7% across channel unit types. Comparisons between the accuracy of species presence and fish abundance models fit using habitat characteristics to those fit using geomorphic channel characteristics indicated similar model accuracy with slightly less bias (6% on average) for the geomorphic channel characteristics models. Our results indicate that the channel types were useful for predicting changes in habitats and stream fish presence and abundance in response to changing streamflow. Channel classification is potentially a useful and cost-effective approach to quantifying changes in the physical environment in response to varying streamflow. Additionally, channel classification could be combined with dynamic fish population models to evaluate the effects of river regulation and water use across large spatial scales.

Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science:8(1):16-22. \| Abstract \| Download	March 2016	Reproductive biology information is an important tool for fishery management actions such as identification of spawning areas and development of protective size limits, bag limits and seasons. 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.

Ecology of Freshwater Fish. http://doi.org/10.1111/eff.12767 \| Abstract	February 2024	Fish exhibit a diverse range of traits encompassing life history strategies, feeding behaviors, and spawning behaviors. These traits mediate fish population responses to changing environmental conditions such as those caused by anthropogenic stressors. The Conasauga River, located in northwestern Georgia and southeastern Tennessee, USA, hosts a diverse assemblage of over 75 species of freshwater fish, some of which are locally or regionally endemic, and many of which are imperiled. Annual monitoring data have shown population declines in multiple fish species of conservation concern in the Conasauga River since at least the 1990s, raising the possibility that other taxa could be declining as well. We quantified temporal change in fish communities at six shoal sites sampled annually in most years from 1996 to 2022, and asked whether species traits hypothesized to underlie population vulnerability to environmental alteration were correlated with species-specific trends for 32 taxa. We estimated that total counts of fish in annual samples declined by ~ 2% per year, although declines were uneven among species and generally greater for less abundant taxa. Tests for species traits corresponding to temporal population trends provided evidence that crevice-spawning minnows and smaller-bodied taxa had steeper declines compared with broadcast spawners and larger, longer-lived, more fecund taxa. Lower abundance, reliance on a particular habitat feature, and life-history traits that may limit population resilience to disturbance may all prove useful for identifying riverine fishes at particular risk of future population decline.

Maintaining critical foraging and breeding habitat for the endangered red-cockaded woodpecker (Picoides borealis) requires an uninterrupted supply of old-growth forest.

Our model accommodates stochastic disturbances and hardwood succession rates, and uncertainty about model structure. We produced a regeneration policy that was indexed by current forest state and by current weight of evidence among alternative model forms. We used adaptive stochastic dynamic programming, which anticipates that model probabilities, as well as forest states, may change through time, with consequent evolution of the optimal decision for any given forest state. In light of considerable uncertainty about forest dynamics, we analyzed a set of competing models incorporating extreme, but plausible, parameter values. Under any of these models, forest silviculture practices currently recommended for the creation of woodpecker habitat are suboptimal. We endorse fully adaptive approaches to the management of endangered species habitats in which predictive modeling, monitoring, and assessment are tightly linked.

Managers of southern U.S. forests who are charged with maintaining habitat for the endangered red-cockaded woodpecker must plan for an uninterrupted supply of old-growth forest stands that provide the critical breeding and foraging habitat for the bird. We constructed and optimized a dynamic model of forest growth and hardwood succession at the Piedmont National Wildlife Refuge (Georgia, USA) for the objective of maintaining a maximum stream of old-growth forest habitat over the infinite time frame. Our model accommodates stochastic disturbances and hardwood succession rates, as well as uncertainty about the structure of the model itself. We produced a decision policy that was indexed not only by current state of the forest, but also by current weight of evidence toward or against alternative forms of the model. We employed adaptive stochastic dynamic programming, which anticipates that model probabilities, as well as forest states, may change through time, with the result that the optimal decision for a given forest state can evolve over time. In light of considerable uncertainty about forest dynamics, we analyzed a set of models that spanned extremes in parameter values. Nevertheless, our analyses suggested that, under any of these models, forest silviculture practices currently employed for woodpecker recovery are suboptimal for the creation of woodpecker habitat. We endorse a fully adaptive approach to the management of endangered species habitats, in which predictive modeling, monitoring, and assessment are tightly linked.

Models are necessary components of adaptive management. Under this approach, uncertainty about the behavior of a managed system is explicitly captured in a set of alternative models. The models generate testable predictions about the response of populations to management, and monitoring data provide the basis for assessing these predictions and informing future management decisions. To illustrate these principles, we examine forest management at the Piedmont National Wildlife Refuge, where management attention is focused on the recovery of the Red-cockaded Woodpecker (Picoides borealis) population. However, managers are also sensitive to the habitat needs of many non-target organisms, including Wood Thrushes (Hylocichla mustelina) and other forest interior Neotropical migratory birds. By simulating several management policies on a set of alternative forest and bird models, we found a decision policy that maximized a composite response by woodpeckers and Wood Thrushes despite our complete uncertainty regarding system behavior. Furthermore, we used monitoring data to update our measure of belief in each alternative model following one cycle of forest management. This reduction of uncertainty translates into a reallocation of model influence on the choice of optimal decision action at the next decision opportunity.

Where decision making can be replicated across units of a landscape, learning can be accelerated, and biological processes can be understood in a larger spatial context. Broad-based partnerships among land management agencies, exemplified by Landscape Conservation Cooperatives (conservation partnerships created through the U.S. Department of the Interior), are potentially ideal environments for implementing spatially-structured adaptive management programs.

Journal of Ornithology 152:S339-S353. \| Abstract \| Download \| Publisher Website	February 2012	The release of animals to reestablish an extirpated population is a decision problem that is often attended by considerable uncertainty about the probability of success. Annual releases of captive-reared juvenile Whooping Cranes (Grus americana) were begun in 1993 in central Florida, USA, to establish a breeding, non-migratory population. Over a 12-year period, 286 birds were released, but by 2004, the introduced flock had produced only four wild-fledged birds. Consequently, releases were halted over managers’ concerns about the performance of the released flock and uncertainty about the efficacy of further releases. We used data on marked, released birds to develop predictive models for addressing whether releases should be resumed, and if so, under what schedule. To examine the outcome of different release scenarios, we simulated the survival and productivity of individual female birds under a baseline model that recognized age and breeding-class structure and which incorporated empirically estimated stochastic elements. As data on wild-fledged birds from captive-reared parents were sparse, a key uncertainty that confronts release decision-making is whether captive-reared birds and their offspring share the same vital rates. Therefore, we used data on the only population of wild Whooping Cranes in existence to construct two alternatives to the baseline model. The probability of population persistence was highly sensitive to the choice of these three models. Under the baseline model, extirpation of the population was nearly certain under any scenario of resumed releases. In contrast, the model based on estimates from wild birds projected a high probability of persistence under any release scenario, including cessation of releases. Therefore, belief in either of these models suggests that further releases are an ineffective use of resources. In the third model, which simulated a population Allee effect, population persistence was sensitive to the release decision: high persistence probability was achieved only through the release of more birds, whereas extirpation was highly probable with cessation of releases. Despite substantial investment of time and effort in the release program, evidence collected to date does not favor one model over another; therefore, any decision about further releases must be made under considerable biological uncertainty. However, given an assignment of credibility weight to each model, a best, informed decision about releases can be made under uncertainty. Furthermore, if managers can periodically revisit the release decision and collect monitoring data to further inform the models, then managers have a basis for confronting uncertainty and adaptively managing releases through time.

Computers and Electronics in Agriculture 27:25-39. \| Abstract \| Download \| Publisher Website	June 2000	Managers of forest wildlife populations make recurring management decisions based on incomplete knowledge of system states. For example, animal population estimates may ignore spatial structure that may influence population viability. We built a spatially-explicit model for a population of birds in a forested landscape. Rates of bird population growth within forest compartments and rates of bird dispersal among compartments were functions of stand age and basal area, compartment population size, and inter-compartment distance. Stand characteristics were imbedded in a dynamic model and assumed perfectly observable and under the complete control of managers. We constructed a genetic algorithm to search for the schedule and spatial distribution of silviculture to maximize total bird abundance at the end of a fixed planning horizon, under combinations of initial habitat and population distribution. We also found policies for a smaller set of population distributions that a manager may only presume to occur (e.g. birds equally distributed among stands), as when managers are only able to observe abundance and not spatial distribution. We investigated the effect of this loss of system resolution on optimality by examining differences in projected population sizes under the two types of policies. That is, we used the set of ‘presumed-state’ policies to project population size from each true initial system state, then we compared these to projections under the best policy for that state. For the planning horizon that we considered, loss in optimality was highly dependent on initial habitat state and on choice of presumed population distribution. Generally, loss in optimality and species extinction rate were both greater for habitat states that were initially poor than initially favorable. For some initial habitat states, population projections based on policies for presumed states often exceeded objective function values for known-state policies, suggesting that the genetic algorithm frequently fell short of finding bona fide optima.

Transactions of the American Fisheries Society 139: 29-48 \| Abstract	January 2010	Water regulation and use have been identified as important limiting factors influencing stream-dwelling fishes. To develop effective water management strategies, fisheries biologists need tools for assessing the effect of reduced streamflows on fish communities. We studied fish assemblages in the lower Flint River Basin, Georgia, during two drought years with very low streamflow (2001-2002) and two years post-drought (2003-2004) with average to above average streamflow. Fishes were sampled and stream discharge measured during the spring, summer, and winter of each year. Analysis of fish assemblage metrics indicated that fish species richness and total fish density were strongly and positively related to seasonal 10-day low discharge. However, the effect of discharge varied with stream size and geomorphic channel characteristics, which suggested that a single low flow standard was unlikely to have the same effect across all streams in the basin. The effect of seasonal base flows also was greater in the spring and summer compared to the winter. Hierarchical occupancy models indicated that the species most sensitive to low base flows were those that were large bodied, those that were intolerant to anthropogenic alterations, and those that occupied deep and fast current velocity habitats. When conducting environmental flow assessments at regional scales, managers should consider the effects of local stream reach characteristics on the response of fishes to streamflow alteration.

Hidden in plain sight: integrated population models to resolve partially observable latent population structure. Ecosphere 13(12):e4321 \| Abstract \| Download \| Publisher Website	December 2022	State uncertainty of individuals within sampled populations is a ubiquitous problem in applied conservation, particularly for stage- or size-structured species subject to consumptive use. We constructed a Bayesian integrated population model (IPM) for American alligators (<i>Alligator mississippiensis</i>) in Georgetown County, South Carolina, USA using records of mark-recapture-recovery, clutch size, harvest, and nightlight survey counts collected locally, and auxiliary information on fecundity, sex ratio, and growth from other studies. We created a multistate mark-recapture-recovery model with six size classes to estimate survival probability, and we linked it to a state-space count model to derive estimates of size class-specific detection probability and abundance. Because we worked from a count dataset in which 60% of the original observations were of unknown size, we treated size class as a latent property of detections and developed a novel observation model to make use of information where size could be partly observed. Detection probability was positively associated with alligator size and water temperature, and negatively influenced by water level. Survival probability was lowest in the smallest size class (hatchlings) but was relatively similar among the other five size classes (>0.90 for each). While the two nightlight survey count sites exhibited relatively stable population trends, we detected substantially different patterns in size class-specific abundance and trends between each site, including 30–50% declines in the largest size classes at the site with greater hunting activity. Here, we illustrate the use of IPMs to produce high resolution output of latent population structure that is partially observed during the monitoring process.

Transactions of the American Fisheries Society 143:565-572. \| Abstract \| Download	April 2014	Intersex fish are increasingly being reported worldwide, primarily in rivers that receive treated wastewater, but few studies have investigated intersex in waters that do not receive wastewater. In a recent reconnaissance survey of intersex fish in North America, a high rate of intersex was reported for Largemouth Bass Micropterus salmoides in some southeastern US rivers; however, the occurrence of intersex in impoundments has not been well-described, especially on a statewide scale. Therefore, our objective for this project was to survey the occurrence of intersex Largemouth Bass in a variety of impoundment habitats across Georgia. Largemouth Bass were collected from 11 impoundments without direct municipal or agricultural wastewater inputs. Gonads from all male Largemouth Bass were evaluated for the incidence and severity of the intersex condition based on presence and arrangement of testicular oocytes. Overall 48% of male Largemouth Bass collected from impoundments were intersex, which was found in 9 of the 11 impoundments. Among impoundments, incidence of intersex ranged from 0 - 82% of the males sampled and surface area of the impoundment was a strong predictor of intersex incidence (R = 0.88, p = 0.0003, n=11). Intersex fish were smaller than normal males but population-level effects of intersex and causative factors of endocrine disruption in the impoundments remain unknown. The high incidence of intersex males in small impoundments demonstrates that the condition is not confined to rivers and suggests that factors other than those previously associated with intersex (i.e., municipal wastewater) may be involved.

Optimization of Scat Detection Methods for a Social Ungulate, the Wild Pig, and Experimental Evaluation of Factors Affecting Detection of Scat. PLOS ONE 11(5): e0155615. https://doi.org/10.1371/journal.pone.0155615 \| Abstract	May 2016	Collection of scat samples is common in wildlife research, particularly for genetic capture-mark-recapture applications. Due to high degradation rates of genetic material in scat, large numbers of samples must be collected to generate robust estimates. Optimization of sampling approaches to account for taxa-specific patterns of scat deposition is, therefore, necessary to ensure sufficient sample collection. While scat collection methods have been widely studied in carnivores, research to maximize scat collection and noninvasive sampling efficiency for social ungulates is lacking. Further, environmental factors or scat morphology may influence detection of scat by observers. We contrasted performance of novel radial search protocols with existing adaptive cluster sampling protocols to quantify differences in observed amounts of wild pig (Sus scrofa) scat. We also evaluated the effects of environmental (percentage of vegetative ground cover and occurrence of rain immediately prior to sampling) and scat characteristics (fecal pellet size and number) on the detectability of scat by observers. We found that 15- and 20-m radial search protocols resulted in greater numbers of scats encountered than the previously used adaptive cluster sampling approach across habitat types, and that fecal pellet size, number of fecal pellets, percent vegetative ground cover, and recent rain events were significant predictors of scat detection. Our results suggest that use of a fixed-width radial search protocol may increase the number of scats detected for wild pigs, or other social ungulates, allowing more robust estimation of population metrics using noninvasive genetic sampling methods. Further, as fecal pellet size affected scat detection, juvenile or smaller-sized animals may be less detectable than adult or large animals, which could introduce bias into abundance estimates. Knowledge of relationships between environmental variables and scat detection may allow researchers to optimize sampling protocols to maximize utility of noninvasive sampling for wild pigs and other social ungulates.

Canadian Journal of Fisheries and Aquatic Sciences. \| Abstract \| Publisher Website	July 2015	The St. Marys River (SMR) historically has been a major producer of sea lamprey (Petromyzon marinus) in the Laurentian Great Lakes. In the early 2000s, a decision analysis (DA) project was conducted to evaluate sea lamprey control policies for the SMR; this project suggested that an integrated policy of trapping, sterile male releases, and Bayluscide treatment was the most cost-effective policy. Further, it concluded that formal assessment of larval sea lamprey abundance and distribution in the SMR would be valuable for future evaluation of control strategies. We updated this earlier analysis, adding information from annual larval assessments conducted since 1999 and evaluating additional control policies. Bayluscide treatments continued to be critical for sea lamprey control, but high recruitment compensation minimized the effectiveness of trapping and sterile male release under current feasible ranges. Because Bayluscide control is costly, development of strategies to enhance trapping success remains a priority. This study illustrates benefits of an adaptive management cycle, wherein models inform decisions, are updated based on learning achieved from those decisions, and ultimately inform future decisions.

Congratulations on Your Promotion to Management: Considerations for New Supervisory Biologists. 2020. Journal of the Southeastern Association of Fish and Wildlife Agencies 7:103-113. \| Abstract \| Publisher Website	March 2020	During the past decade, many senior leaders in natural resource management organizations retired and new leaders were recruited to replace them. The new supervisory biologists now find themselves tasked with operational responsibilities (e.g., personnel, budgets, procurement, safety) with limited formal training in those areas. This sudden role change can be jolting, but need not be debilitating. Here we present information and guidance on various topics ranging from recruiting new personnel and conducting performance evaluations to maintaining a sound safety program as well as legal considerations regarding personal and institutional liabilities for job-related issues. Often, your first task as the new supervisor is to oversee a recruitment effort to fill your old position. This first task is best accomplished by working closely with the designated human resources staff to meet all administrative requirements and deadlines. After the successful hire, effective team leadership is achieved by learning how each staff member is motivated, what they are best able to contribute to the team, and areas for which they may need support. As a new supervisor, you are now responsible for promoting your agency’s safety program to mitigate potential job-related hazards. Despite institutional safeguards, accidents happen or interpersonal interactions can go poorly, and the aggrieved party may litigate for due compensation or to punish the perceived wrongdoer. As a supervisor, you may be a party to these litigations, and understanding your responsibilities in these situations is important for keeping you, your supervisees, and your institution safe and free of liability and help to hold any responsible party accountable when accidents, harassment, bias, or bullying occur. We hope the information provided here will facilitate a smooth transition from mid-career biologist to a supervisory biologist who can efficiently carryout their agency’s mission in natural resource stewardship.

Journal of the Southeastern Association of Fish and Wildlife Agencies 5:39-45. \| Abstract	March 2018	Blue catfish (Ictalurus furcatus) are native to the Coosa River drainage in northwest Georgia, but have been widely introduced outside of this range, including Lake Oconee, a 7677-ha impoundment on the Oconee River in central Georgia. Blue catfish abundance and growth rates have increased dramatically since their introduction in Lake Oconee, but their food habits are unknown. Therefore, food habits of blue catfish in this impoundment were determined by examining the stomachs of 808 specimens in the reservoir’s upper and lower regions across all seasons from summer 2012 to summer 2013. Diet was summarized using the Relative Importance of specific prey by weight. In the upper region of the reservoir, Asian clams (Corbicula fluminea) were the dominant prey item during the summer (75.7%), fall (66.4%), and winter (37.6%); whereas, crappie (Pomoxis spp.) was the dominant prey item in the spring (38.7%). Asian clams also were the dominant prey items in the lower region during the fall (68.4%) and winter (33.9%), and spring (36.4%). Blue catfish seemed to feed opportunistically on seasonally abundant prey items in both the upper riverine and lower lacustrine portions of the reservoir. Of the many sportfishes in the reservoir, only crappie was an important prey item in the upper region during the spring. Our results do not support concerns that blue catfish are an apex predator that would decimate the sportfish assemblage in the recently colonized reservoir.

Environmental Biology of Fishes 87:43-53. \| Abstract \| Download	January 2010	Robust redhorse (Moxostoma robustum) is a rare riverine sucker for which life history information is scarce. Spawning occurs over loose gravel substrate and eggs and larvae may be adversely affected by fine sediments among the gravel. A 2-year study was conducted to determine the threshold at which fine sediments are detrimental to successful egg incubation and larval emergence. Year 1 gravel treatments contained 0, 25, 50, and 75% fine sediments. Mean survival during Year1 ranged from 63.5% in the 0% fine sediment treatment to 0% in the 75% fine sediment treatment. The results also indicated an adverse affect threshold between 0 and 25 % fine sediment. Year 2 gravel treatments contained 0, 5, 10, 15, 20 and 25% fine sediments. Mean survival during Year 2 ranged from 69.8% in the 0% treatment to 9.1% in the 25% treatment. Year 2 results also identified the 15% fine sediment treatment as the threshold at which survival begins to decline. Substrates at one known spawning area used by robust redhorse typically contain 25 to 50% fine sediment, but the spawning act is cleans some fines from the egg pocket. Whether the “cleaning” that results from the spawning act reduces the fines sufficiently to avoid adverse effects is unknown. According to our results, survival rates of robust redhorse eggs and larvae are predicted to be about 8.0% when fine sediment is > 25%.

Conservation agencies tasked with reserve design may benefit from a dynamic decision system that provides tactical guidance for short-term decision opportunities while maintaining focus on a long-term objective of assembling the best set of protected areas possible. To plan cost-effective conservation over time under time-varying action costs and budget, we propose a multi-period mixed integer programming model for the budget-constrained selection of fully connected sites. The objective is to maximize a summed conservation value over all network parcels at the end of the planning horizon. The originality of this work is in achieving full spatial connectivity of the selected sites during the schedule of conservation actions.

We assessed 28 coastal Georgia vertebrate species for their exposure to potential habitat changes due to SLR using output from the Sea Level Affecting Marshes Model and information on the species’ fundamental niches. We assessed forecasted habitat change up to the year 2100 using three structural habitat metrics: total area, patch size, and habitat permanence. Almost all of the species (n = 24) experienced negative habitat changes due to SLR as measured by at least one of the metrics. Salt marsh and ocean beach habitats experienced the most change (out of 16 categorical land cover types) across the three metrics and species that used salt marsh extensively (rails and marsh sparrows) were ranked highest for exposure to habitat changes. Species that nested on ocean beaches (Diamondback Terrapins, shorebirds, and terns) were also ranked highly, but their use of other foraging habitats reduced their overall exposure. Future studies on potential effects of SLR on vertebrates in southeastern coastal ecosystems should focus on the relative importance of different habitat types to these species’ foraging and nesting requirements. Our straightforward prioritization approach is applicable to other coastal systems and can provide insight to managers on which species to focus resources, what components of their habitats need to be protected, and which locations in the study area will provide habitat refuges in the face of SLR.

We developed a Web-based decision support tool (DST) for the U.S. Fish and Wildlife Service and the U.S. Geological Survey initiative. The DST facilitates cross-organizational data sharing, performs analyses to improve conservation delivery, and requires no technical expertise to operate. Each year since 2012, the DST has used monitoring data to update ecological knowledge that it translates into situation-specific management-action recommendations (e.g., controlled burn or prescribed graze). The DST provides annual recommendations for more than 10,000 acres on 20 refuge complexes in four U.S. states. We describe how the DST promotes the long-term implementation of the program for which it was designed and may facilitate decision support and improve ecological outcomes of other conservation efforts.

Conservation of northern bobwhite on private lands in Georgia, USA under uncertainty about landscape level habitat effects. Landscape Ecology 24:405-418. \| Abstract \| Download \| Publisher Website	March 2009	Large-scale habitat enhancement programs for birds are becoming more widespread, however, most lack monitoring to resolve uncertainties and enhance program impact over time. Georgia’s Bobwhite Quail Initiative (BQI) is a competitive, proposal-based system that provides incentives to landowners to establish habitat for northern bobwhites (Colinus virginianus). Using data from monitoring conducted in the program’s first years (1999–2001), we developed alternative hierarchical models to predict bobwhite abundance in response to program habitat modifications on local and regional scales. Effects of habitat and habitat management on bobwhite population response varied among geographical scales, but high measurement variability rendered the specific nature of these scaled effects equivocal. Under some models, BQI had positive impact at both local farm scales (1, 9 km2), particularly when practice acres were clustered, whereas other credible models indicated that bird response did not depend on spatial arrangement of practices. Thus, uncertainty about landscape-level effects of management presents a challenge to program managers who must decide which proposals to accept. We demonstrate that optimal selection decisions can be made despite this uncertainty and that uncertainty can be reduced over time, with consequent improvement in management efficacy. However, such an adaptive approach to BQI program implementation would require the reestablishment of monitoring of bobwhite abundance, an effort for which funding was discontinued in 2002. For landscape-level conservation programs generally, our approach demonstrates the value in assessing multiple scales of impact of habitat modification programs, and it reveals the utility of addressing management uncertainty through multiple decision models and system monitoring.

Fisheries Management and Ecology 16:68-71 \| Abstract \| Publisher Website	January 2009	Research and management of rare or cryptic fishes often is hampered by an inability to consistently collect sufficient numbers of individuals. We present data from studies of robust redhorse Moxostoma robustum in the Ocmulgee River, Georgia as a case study illustrating the effectiveness of using radio-tagged, hatchery-reared individuals as “guide fish” to direct sampling efforts and locate spawning aggregations of resident fish. Catch per unit effort of untagged robust redhorse was higher when we focused electrofishing effort on areas occupied by radio-tagged individuals compared to areas not occupied by radio-tagged individuals or past survey efforts. Tracking of two radio-tagged robust redhorse led us to two previously unknown spawning aggregations of resident fish. The use of radio-tagged “guide fish” should be considered if data on rare or cryptic species are difficult to obtain.

Aquatic Conservation: Marine and Freshwater Ecosystems 19:170-177. \| Abstract \| Publisher Website	January 2009	Robust redhorse Moxostoma robustum is an imperiled, potadromous fish in the southeastern United States. Initial recovery efforts have focused on supplementing existing populations and establishing refugial populations through extensive stocking programs. However, assessment of the success of these programs has not yet been conducted, and there are few reports evaluating the effectiveness of such programs with other potadromous species. 2. Radio telemetry was employed to assess the effectiveness of a stocking program aimed at addressing whether stocked individuals would remain in an area free of introduced predators and ascertaining the ability of stocked fish to integrate into a resident population. 3. Hatchery-reared robust redhorse were captured from refugial populations established in other river systems and were transferred to the Ocmulgee River, Georgia where a population hatchery-reared individuals and an unknown number of wild fish resides. 4. These transferred robust redhorse exhibited an exploratory phase for the first three months before adopting behavior patterns, including spawning migrations that were consistent with those reported for wild fish in other systems. However, some individuals seemed unable to locate suitable spawning habitat. 5. Approximately half of the radio-tagged fish remained within the area free of introduced predators. 6. At least some radio-tagged robust redhorse fully integrated into the resident population as evidenced by their presence in spawning aggregations with resident individuals. 7. The effectiveness of a stocking program is dependent upon the ability of stocked individuals to integrate into an existing population /or replicate the behavior and functionality of a resident population. Evaluations of stocking programs should incorporate assessments of behavior in addition to surveys to estimate abundance and survivorship and genetic assessments of augmentation of effective population sizes.

North American Journal of Fisheries Management 29:721–729. \| Abstract \| Publisher Website	June 2009	Conservation and management of riverine species, such as robust redhorse Moxostoma robustum, can be hindered by incomplete understanding of their population status. Behavioral responses to sampling methodologies and susceptibility to capture with a particular gear type has implications to the reliability of population assessments, yet are rarely evaluated. Consequently, we used radio-tagged robust redhorse in the Ocmulgee River, Georgia, to estimate capture probability when sampled with standard boat-electrofishing techniques and assess behavioral responses of individuals to single and repeated exposures to electrofishing, which is the recommended sampling method for this species. Transects containing 1-8 radio-tagged individuals were sampled. The positions of radio-tagged individuals were recorded prior to electrofishing and at 1-h, 24-h, and 3-5 d intervals after sampling. We estimated robust redhorse abundance and capture probability by treating each transect as analogous to a repeated sample in time. Only one radio-tagged individual and six untagged individuals were captured after 7.46 h of effort. Radio-tagged robust redhorse did not exhibit an immediate response to boat electrofishing. Some movement away from their original position was observed in radio-tagged robust redhorse within the first hour post-electrofishing (mean ± SE: 0.15 ± 0.05 km; range: 0.0-0.80 km), after 24 h (0.19 ± 0.05 km), and after 3-5 days (0.23 ± 0.14 km). However, this movement was similar from that exhibited by fish located at similar intervals during a related telemetry study without exposure to electrofishing. A mean capture probability of 0.031 with 95% Bayesian credibility intervals of 0.002-0.111 was estimated from the best approximating model. Electrofishing is not a particularly effective method for capturing this species; therefore, inferences about population size and distribution of this or other cryptic species need to account for low detection probabilities associated with electrofishing. Alternative approaches or multiple strategies should be considered when assessing the status of such species.

Proceedings of the 22nd North American Prairie Conference, 1-5 August 2010, University of Northern Iowa, Cedar Falls, IA. \| Abstract \| Download \| Publisher Website	April 2012	Much of the native prairie managed by the U.S. Fish and Wildlife Service (Service) in the Prairie Pothole Region (PPR) of the northern Great Plains is extensively invaded by the introduced cool-season grasses smooth brome (Bromus inermis) and Kentucky bluegrass (Poa pratensis). Management to suppress these invasive plants has had poor to inconsistent success. The central challenge to managers is selecting appropriate management actions in the face of biological and environmental uncertainties. In partnership with the Service, the U.S. Geological Survey is developing an adaptive decision support framework to assist managers in selecting management actions under uncertainty and maximizing learning from management outcomes. The framework is built around practical constraints faced by refuge managers and includes identification of the management objective and strategies, analysis of uncertainty and construction of competing decision models, monitoring, and mechanisms for model feedback and decision selection. Nineteen Service field stations, spanning four states of the PPR, are participating in the project. They share a common management objective, available management strategies, and biological uncertainties. While the scope is broad, the project interfaces with individual land managers who provide refuge-specific information and receive updated decision guidance that incorporates understanding gained from the collective experience of all cooperators. We describe the technical components of this approach, how the components integrate and inform each other, how data feedback from individual cooperators serves to reduce uncertainty across the whole region, and how a successful adaptive management project is coordinated and maintained on a large scale.

Fundación Biodiversidad, Madrid, Spain. \| Abstract \| Download	October 2009	We translocated 32 bobcats (Lynx rufus; 3.1 bobcats/10 km2) to a coastal barrier island, Cumberland Island, Georgia, USA, during 1988-1989 to restore a native predator. In this paper, we summarize our methods of capturing and handling bobcats and results of post-release monitoring of movements, survival, and reproduction. We use this as an opportunity to (1) identify key lessons we learned that could be useful for future felid reintroductions, (2) demonstrate the importance of post-reintroduction monitoring to learn more about the role of predators in ecosystem functioning, and (3) summarize insights we have gained about bobcat prey selection and social organization in a solitary felid. Also, we present previously unpublished data that provide evidence for bobcats initiating a top-down trophic cascade on the Cumberland Island forested ecosystem. We captured bobcats from the coastal plain of Georgia in the hope that these bobcats would have gene complexes adapted to the environment on Cumberland Island. Captured bobcats were temporarily held in a facility on the mainland so that groups of 4-6 individuals could be translocated and released on the island in fall 1988 and 1989. All reintroduced bobcats were vaccinated for three common feline diseases and fitted with radio-collars. Post-release monitoring included radio-telemetry to monitor movements, spatial organization, and survival, re-capture to assess body condition and replace radio-collars, prey surveys to assess food abundance, and scat collection to assess prey use. We analyzed white-tailed deer (Odocoileus virginianus) harvest data from 1980-1997 to assess changes in the deer population (body weights, age-sex structure, and abundance) because deer were a dominant prey species during our post-release monitoring of 1988-1991. Also, because browsing by deer suppressed oak (Quercus spp.) regeneration prior to the bobcat reintroduction, we investigated whether declines in deer abundance resulted in increased numbers and size of seedlings and root sprouts of these tree species. We reintroduced three males and 11 females in fall 1988 and 12 males and six females in fall 1989. One female released in 1988 returned to the mainland, another died from physical injuries, and one male released in 1989 swam into the Atlantic Ocean and presumably drowned. However, annual survival of adults was 93% (SE = 2.6%) for the first three years and recaptured bobcats exhibited an average weight gain of 0.8 kg (12% increase). We documented reproduction of 10 kittens in 1989 (4 litters), one litter of two kittens in 1990, and one litter of two kittens in 1991. Bobcat prey abundance varied spatially and seasonally, but we detected no effect of season or year on diet composition during 1989-90. Marsh rabbits (Sylvilagus palustris), white-tailed deer, and hispid cotton rats (Sigmodon hispidus) were the only prey species identified in bobcat scats in all seasons and we considered these species principal prey. Only the presence of marsh rabbits and cotton rats in bobcat diets were correlated with abundance, which suggested bobcats exhibited a functional response to these prey species. Diet species diversity and richness were negatively correlated with marsh rabbit abundance, which agrees with predictions of a diet optimization model in which alternate prey species (raccoon [Procyon lotor], feral hogs [Sus scrofa], and cotton deermice [Peromyscus gossypinus]) increased with a decrease in abundance of a preferred prey species. By 1997-1998, prey use changed, in which white-tailed deer and marsh rabbits occurred less frequently in scats and all other species occurred more frequently. Female bobcats reintroduced during the first year of the reintroduction exhibited little change in the location or size of their home range (95% fixed kernel utilization distribution), but failed to exclude newcomers reintroduced in 1989 from either their home range or core areas (50% fixed kernel utilization distribution). No bobcats retained areas of exclusive use from conspecifics of the same sex. We observed increasing intrasexual overlap among females during 1989-91, such that each home range overlap was equivalent to each female sharing her home range with >2 other females. Overlap of core areas was equivalent to each female sharing her core area with nearly one other female. Mean eviscerated body weights of harvested white-tailed deer increased 5.0–7.6 kg for males and 2.0–4.9 kg for females between the pre-reintroduction years (1984-1989) and post-reintroduction years (1990-1997). Eviscerated body weights were 11.0 kg greater in 1997 compared to 1989 (average difference of means by age-sex class). Estimates and indices of deer abundance indicated that following reintroduction of bobcats the population declined and remained low. Population estimates indicated hunter success rates declined following the bobcat reintroduction, even though the number of hunters prior to the reintroduction ( = 270 hunters/year) differed little from after the reintroduction of bobcats ( = 278 hunters/year). On nine plots containing 87 oak trees, where oak regeneration at each tree was measured in 1990, the number of trees with seedlings or root sprouts increased from 52 to 86 and the average number of seedlings per plot increased by 153.5. On plots that contained seedlings and sprouts in both 1990 and 1997, average height increased 4.6 cm (95% CI = 4.0–5.2). We were able to successfully capture and translocate approximately 15 bobcats per year, although we were not able to capture enough bobcats to control the sex ratio of the population of reintroduced bobcats; at the conclusion of the translocations in 1989 the reintroduced population consisted of 14 males and 15 females, although it was female-biased (11females, 3 males) after the translocations in 1988. This introduced potential confounding effects when interpreting results of our post-release monitoring of food habits and spatial organization. We strongly recommend that future reintroduction projects establish a means of conducting ‘soft’ releases of animals whereby animals are held in captivity at the release site and allowed to leave captivity following a waiting period. Even holding bobcats overnight might have prevented the disorientation of the released bobcat that swam into the Atlantic Ocean and presumably drowned. A dramatic population decline in marsh rabbits, caused by above-normal rainfall from a hurricane, allowed us to detect changes in bobcat diets and identify a functional response to prey abundance and evidence for diet optimization. The frequency of occurrence of deer in bobcat diets year-round (23–47%) was greater than reported for other studies in the southeastern United States (0–8%). Although we did not have sufficient data to identify the shape of these functional relationships, bobcat diets in 1997-1998 had lower occurrence of marsh rabbits and deer and a more even distribution of occurrence of all prey species in their diet. Also, there was no evidence the frequent occurrence of deer in the diet was because of a lack of food availability because bobcat survival was high, recaptured bobcats exhibited weight gains, and bobcats maintained normal home range sizes. Results of the analysis of spatial organization of bobcats were consistent with the hypothesis that bobcats maintain home ranges via a system of land tenure established by prior rights. However, we observed significant intrasexual overlap of both home ranges and core areas. Furthermore, we observed declining reproduction with an increase in home range overlap. We believe that successful reproduction in bobcats may be related to access by females to exclusive use areas even under conditions of adequate or good food availability. Under the conditions of this study (moderate bobcat density, adequate food availability, and limited dispersal) bobcats exhibited no evidence of an ability to exclude other adult individuals from their home ranges or core areas. Our observations of bobcat use of deer as a primary prey species following their reintroduction, a decline in deer abundance, and an increase in oak regeneration indicated that bobcats caused a trophic cascade effect on the island. We did not expect to observe such strong trophic level changes on the island ecosystem because deer generally are not considered primary prey for bobcats. However research prior to the restoration of bobcats indicated deer were abundant and deer browsing suppressed tree regeneration, and apparently deer were suitable prey for bobcats because of their abundance and small size. We believe the results of this study provide strong justification for post-release monitoring of a reintroduced species to be able to understand why a reintroduction project succeeds or fails. Moreover, the role of predators in ecosystems in poorly understood, especially vertebrate predators, and restoration projects of predator populations should consider monitoring trophic level characteristics of ecosystems. If such a monitoring program were developed to test theories of community population dynamics, there would be much potential to better understand food webs of terrestrial ecosystems and trophic level inter-relationships.

Fisheries Research 123-124: 78-89. \| Abstract \| Publisher Website	July 2012	In this paper, we describe our assessment of whether gill nets and hydroacoustics provided similar inferences on the local abundance of fishes and whether gill net catch could be used to predict acoustic-derived abundances. We collected hydroacoustic and gill netting samples from a restricted area of large hydropower reservoir in the southeastern United States. We used mixed linear models in an information theoretic framework to model acoustic-derived abundances as a function of gill net catch and a variety of biological and environmental covariates. Overall, gill net catch was a poor predictor of acoustic-derived abundance and the best model only accounted for 39.6% of the within year variation. In fact, a gill net catch (e.g., 100 fish/net) was approximately equally likely across several orders of magnitude in fish abundance. This result suggests that gill net catch was unable to reliably discern substantive changes in fish abundance. Consequently, the most appropriate role for gill nets in fisheries research assessments may be to: (1) supplement hydroacoustic data by providing information on species composition and fish sizes and (2) provide information on metrics other than fish abundance, such as fish growth and condition.

The longleaf pine <i>Pinus palustris</i> ecological system supports many priority at-risk species designated for review, including five species of herpetofauna: gopher tortoise <i>Gopherus polyphemus</i>, southern hognose snake <i>Heterodon simus</i>, Florida pine snake <i>Pituophis melanoleucus mugitus</i>, gopher frog <i>Lithobates</i> [<i>Rana</i>] <i>capito</i>, and striped newt <i>Notophthalmus perstriatus</i>. To inform status decisions and conservation planning, we developed habitat suitability models to 1) identify habitat features that best predict species presence and 2) estimate the amount and distribution of suitable habitat across each species' range under current conditions. We incorporated expert judgment from Federal, State, and other partners to capture variation in ecological settings across species' ranges, prioritize predictor variables to test in models, mitigate data limitations by informing the selection of pseudo-absence points, qualitatively evaluate model estimates, and improve the likelihood that experts will trust and use model predictions for conservation. Habitat suitability for all species was strongly influenced by soil characteristics, land cover, and fire interval. Suitable habitat was distributed on known species strongholds, as well as private lands without known species records. Between 4.7% (gopher frog) and 14.6% (gopher tortoise) of the area in a species' range was classified as suitable habitat, and between 28.1% (southern hognose snake) and 47.5% (gopher frog) of suitable habitat was located in patches larger than 1 km2 (100 ha) on publicly-owned lands. By overlaying predictions for each species, we identified areas of suitable habitat for multiple species on protected and unprotected lands. These results have direct applications to management and conservation planning: partners can tailor site-level management based on attributes associated with high habitat suitability for species of concern; allocate survey effort in areas with suitable habitat but no known species records; and identify priority areas for management, land acquisitions, or other strategies based on the distribution of species records, suitable habitat, and land protection status. These results can aid regional partners in implementing effective conservation strategies and inform listing decisions of the U.S. Fish and Wildlife Service.

Biological Conservation 222:33-43. https://doi.org/10.1016/j.biocon.2018.03.023 \| Abstract \| Download	June 2018	A challenge for making conservation decisions is predicting how wildlife populations respond to multiple, concurrent threats and potential management strategies, usually under substantial uncertainty. Integrated modeling approaches can improve estimation of demographic rates necessary for making predictions, even for rare or cryptic species with sparse data, but their use in management applications is limited. We developed integrated models for a population of diamondback terrapins (Malaclemys terrapin) impacted by road-associated threats to (i) jointly estimate demographic rates from two mark-recapture datasets, while directly estimating road mortality and the impact of management actions deployed during the study; and (ii) project the population using population viability analysis under simulated management strategies to inform decision-making. Without management, population extirpation was nearly certain due to demographic impacts of road mortality, predators, and vegetation. Installation of novel flashing signage increased survival of terrapins that crossed roads by 30%. Signage, along with small roadside barriers installed during the study, increased population persistence probability, but the population was still predicted to decline. Management strategies that included actions targeting multiple threats and demographic rates resulted in the highest persistence probability, and roadside barriers, which increased adult survival, were predicted to increase persistence more than other actions. Our results support earlier findings showing mitigation of multiple threats is likely required to increase the viability of declining populations. Our approach illustrates how integrated models may be adapted to use limited data efficiently, represent system complexity, evaluate impacts of threats and management actions, and provide decision-relevant information for conservation of at-risk populations.

However, the success of reintroduction efforts has been poorer than many biologists and managers would hope. To increase the benefits gained from reintroduction, management decision making should be couched within formal decision-analytic frameworks. Decision analysis is a structured process for informing decision making that recognizes that all decisions have a set of components—objectives, alternative management actions, predictive models, and optimization methods—that can be decomposed, analyzed, and recomposed to facilitate optimal, transparent decisions. Because the outcome of interest in reintroduction efforts is typically population viability or related metrics, models used in decision analysis efforts for reintroductions will need to include population models. In this special section of the Journal of Wildlife Management, we highlight examples of the construction and use of models for informing management decisions in reintroduced populations. In this introductory contribution, we review concepts in decision analysis, population modeling for analysis of decisions in reintroduction settings, and future directions. Increased use of formal decision analysis, including adaptive management, has great potential to inform reintroduction efforts. Adopting these practices will require close collaboration among managers, decision analysts, population modelers, and field biologists.

Journal of Wildlife Management 77:1145-1156. http://dx.doi.org/10.1002/jwmg.472 \| Abstract \| Download \| Publisher Website	August 2013	Decision making in guidance of reintroduction efforts is made challenging by the substantial scientific uncertainty typically involved. However, a less recognized challenge is that the management objectives are often numerous and complex. Decision makers managing reintroduction efforts are often concerned with more than just how to maximize the probability of reintroduction success from a population perspective. Decision makers are also weighing other concerns such as budget limitations, public support and/or opposition, impacts on the ecosystem, and the need to consider not just a single reintroduction effort, but conservation of the entire species. Multiple objective decision analysis is a powerful tool for formal analysis of such complex decisions.We demonstrate the use of multiple objective decision analysis in the case of the Florida non-migratory whooping crane reintroduction effort. In this case, the State of Florida was considering whether to resume releases of captive-reared crane chicks into the non-migratory whooping crane population in that state. Management objectives under consideration included maximizing the probability of successful population establishment, minimizing costs, maximizing public relations benefits, maximizing the number of birds available for alternative reintroduction efforts, and maximizing learning about the demographic patterns of reintroduced whooping cranes. The State of Florida engaged in a collaborative process with their management partners, first, to evaluate and characterize important uncertainties about system behavior, and next, to formally evaluate the tradeoffs between objectives using the Simple Multi-Attribute Rating Technique (SMART). The recommendation resulting from this process, to continue releases of cranes at a moderate intensity, was adopted by the State of Florida in late 2008. Although continued releases did not receive support from the International Whooping Crane Recovery Team, this approach does provide a template for the formal, transparent consideration of multiple, potentially competing, objectives in reintroduction decision making.

Here we consider three recurrent themes in complicated problems involving complex systems: (1) scale dependencies and cross-scale, often nonlinear relationships; (2) resilience, in particular the potential for complex systems to move to alternate stable states with decreased ecological and/or economic value; and (3) uncertainty in the ability to understand and predict outcomes, perhaps particularly those that occur as a result of human impacts. We consider these issues in the context of landscape-level decision making, using as an example water resources and lotic systems in the Piedmont region of the southeastern United States.

Sources of variation in detection of wading birds from aerial surveys in the Florida Everglades. Auk 125:731-743. \| Abstract \| Download \| Publisher Website	July 2008	We conducted dual-observer trials to estimate detection probabilities (probability that a group that is present and available is detected) for fixed-wing aerial surveys of wading birds in the Everglades system, Florida. Detection probability ranged from <0.2 to ~0.75 and varied according to species, group size, observer, and the observer's position in the aircraft (front or rear seat). Aerial-survey simulations indicated that incomplete detection can have a substantial effect on assessment of population trends, particularly over relatively short intervals (≤3 years) and small annual changes in population size (≤3%). We conclude that detection bias is an important consideration for interpreting observations from aerial surveys of wading birds, potentially limiting the use of these data for comparative purposes and trend analyses. We recommend that workers conducting aerial surveys for wading birds endeavor to reduce observer and other controllable sources of detection bias and account for uncontrollable sources through incorporation of dual-observer or other calibration methods as part of survey design (e.g., using double sampling).

Journal of Wildlife Diseases 51(3)609-618. \| Abstract	July 2015	Intracranial abscess disease is a reported cause of natural mortality for mature, male white-tailed deer (Odocoileus virginianus). Most cases of abscesses are associated with bacterial infection by Trueperella (Arcanobacterium) pyogenes but little else is known about the disease. We examined 7,545 white-tailed deer from 60 sites throughout Georgia (USA) for signs of cranial abscesses, the predecessor of intracranial abscesses, to model risk factors that may contribute to incidence of the disease. Factors examined included environmental factors (soil and forest type), demographic factors (deer density and male to female ratio), and individual host factors (deer gender and age). We found no cases of cranial abscesses in the 2,562 female deer examined but they were found in 91 of the 4,983 (1.8%) male deer examined. A generalized linear mixed model, treating site as a random effect, indicated the probability of a male having a cranial abscess increased with age. Adult sex ratio (male:female) at the site was also positively associated with this disease. Site-specific variables for land cover and soil types were not strongly associated with risk of the disease and a large amount of among-site variability remained. Our results suggest the high incidence of cranial abscesses in some populations could interfere with deer management strategies attempting to increase demographic representation of older males in the population. Given the relative importance of individual and local demographic factors and the remaining unexplained spatial variability, additional investigation into spatiotemporal variation of the presumed bacterial causative agent of cranial abscesses appears warranted.

Postoperative assessments were conducted at 1, 2, 8, 12, and 26 and 55 weeks to visually evaluate the surgical incision for suture retention, incision healing, erythema, and swelling. Incisions were also assessed microscopically at 1, 2, and 8 weeks for necrosis, inflammation, hemorrhage, and fibroplasia. The results indicated that incisions closed with either Vicryl or Prolene suture materials were more likely to exhibit more erythema or incomplete healing compared with those closed with Monocryl or Monocryl-Plus. The surgical implantation of a transmitter in the coelomic cavity did not significantly affect the response variables among the four suture materials. Monocryl or Monocryl-Plus were equally effective and superior to other suture materials used for closing surgical incisions in Siberian Sturgeon or closely related species of sturgeon. Furthermore, Monocryl or Monocryl-Plus may decrease the risk of transmitter expulsion through the incision, as surgical wounds appear to heal faster and exhibit less erythema compared with those closed with Vicryl.

Fisheries Management and Ecology 18:104-112. \| Abstract	April 2011	Overfishing has reduced many shark populations along the east coast of the United States. Many states have recreational and commercial fisheries that occur in nursery areas occupied by sub-adult sharks, which raises concerns about mortality rates for these life stages. Georgia is one of few states without a directed shark fishery; however, the State is home to a large trawl fishery for penaeid shrimp, and small sharks occur as bycatch in shrimp trawls. During fishery-dependent sampling events from 1995-1998, 34% of 127 trawls contained sharks. This bycatch totaled 217 individuals from six species, with Atlantic sharpnose shark, Rhizoprionodon terraenovae (Richardson), the most common, and finetooth, Carcharhinus isodon (Valenciennes), and spinner, Carcharhinus brevipinna (Müller and Henle), sharks the least common. The highest catch rates for sharks occurred during June and July and coincided with the peak months of the pupping season for many species. Fishing characteristics (i.e., tow speed and tow time) did not significantly influence catch rates for shark species. Gear configurations (net type, turtle excluder device, bycatch reduction device) did affect catch rates for shark species. Management strategies that may reduce shark bycatch in this fishery include possible gear restrictions, a delayed season opening or reduced bar spacing on turtle excluder devices.

Marine and Coastal Fisheries: Dynamics, Management and Ecosystem Science 1:218-229. \| Abstract	July 2009	We investigated the utility of a fishery–independent trawl survey for assessing a potential multispecies shark nursery in Georgia’s near and inshore waters. A total of 234 sub-adult sharks from six species were captured during 85 of 216 trawls. Catch rates and size distributions for sub-adult sharks, and the ratio of neonates to juveniles were consistent among areas. The highest concentrations of sub-adult sharks occurred in creeks and sounds. Species composition varied among areas. Atlantic sharpnose shark was the most abundant species in the sound and nearshore stations, whereas bonnetheads were the most abundant species in the creeks. The aggregate of other species occurred with higher frequency in the sounds and nearshore. Sampling characteristics of the trawl survey were compared to those from a fishery–independent sub-adult shark longline survey to assess the similarity of the two gears. A total of 193 sub-adult sharks from seven species were captured during 57 of 96 longline sets, whereas 52 sub-adults from four species were captured during 20 of 48 trawls. Selectivity and efficiency differed between the two gears. The trawl had lower catch rates, caught smaller sharks, and encountered a different suite of species than the longline. General seasonal trends in relative abundance also differed between the two gears, with the longline showing an increasing trend in abundance and the trawl showing a stable trend. Although trawls were not found to be efficient for sampling sub-adult sharks from most species, they can be a useful source of supplemental data.

North American Journal of Fisheries Management 29:1676-1685. \| Abstract	December 2009	Lunar and tidal phases, along with bait type, were examined as potential sources of bias affecting catch rates of sub-adult sharks on hand-retrieved longlines in Georgia’s estuaries. Sampling occurred during April-September from 2001-2003 in eight of Georgia’s nine estuaries when the presence of sub-adult sharks is high. The effects of lunar and tidal phases on catch rates of sharks were evaluated during 2001 and 2002.The effect of bait type (i.e., squid Loligo spp. or spot Leiostomus xanthurus) on catch rates of sharks was evaluated during 2003. During 2001 and 2002, 420 sub-adult sharks, representing two families (Carcharhinidae and Sphyrnidae) and nine species, were caught during 212 longline sets. Catch rates were evaluated for the four most commonly occurring species, Atlantic sharpnose Rhizoprionodon terranovae, bonnethead Sphyrna tiburo, blacktip Carcharhinus limbatus and sandbar C. plumbeus sharks, as well as the aggregate catch rate of all sub-adult sharks. Neither lunar cycle nor tidal stage affected catch rates of any species other than blacktip sharks. In 2003, longline sets (n=80 sets) resulted in the capture of 177 sub-adult sharks from seven species. Overall catch rates were higher with squid than with spot, and bait type also affected shark species catch composition. Further, mean sizes of Atlantic sharpnose sharks were significantly different between the two bait types, indicating a possible ontogenetic shift in bait preference. For example, catch of neonate Atlantic sharpnose sharks was higher on hooks baited with squid than on hooks baited with spot, whereas catch of juveniles was higher on hooks baited with spot. Although timing of sampling did not influence catch rates of sub-adult sharks, bait choice could bias estimates of abundance for life certain stages and can affect the probability of detecting some species.

During 231 longline sets, we captured 415 individuals representing nine species. Atlantic sharpnose shark (Rhizoprionodon terranovae), bonnethead shark (Sphyrna tiburo), blacktip shark (Carcharhinus limbatus) and sandbar shark (C. plumbeus) comprised 96.1% of the catch. Canonical Correlation Analysis (CCA) was used to assess environmental influences on the assemblage of the four common species, and indicated bonnethead sharks and sandbar sharks were correlated with each other and with a subset of environmental variables. Discriminant Analyses (DA) were used to assess environmental influences on individual species, and also indicated correlations between selected species and a subset of environmental variables. Although significant relationships existed at each level of analysis, dissolved oxygen, salinity, turbidity, and depth accounted < 16% of the total variation in each. Macrohabitat, prey availability, and susceptibility to predation may have stronger influences on the presence and distribution of sub-adult shark species among sites.

Endangered Species Research 51: 203-214. https://doi.org/10.3354/esr01250 \| Abstract	July 2023	<sup>The Atlantic Sturgeon (<i>Acipenser oxyrinchus oxyrinchus</i>) was once of great commercial importance in many coastal rivers of the eastern U.S.A. Over the 19<sup>th</sup>–20<sup>th</sup> centuries, most historical stocks of Atlantic Sturgeon were depleted by human activities. Estimating recruitment for the remaining populations is challenging due to sampling constraints, limited age data, and natural variability. However, recruitment estimates could inform recovery efforts. The objectives of this study were to compare two modeling approaches to estimate recruitment of age-1 Atlantic Sturgeon and provide an updated index of abundance across more than a decade of sampling in the Altamaha River, GA. First, we constructed capture histories of river-resident juveniles, using capture-mark-recapture data collected from 2008–2020, and assigned ages based on length-frequency analysis. Second, we compared more traditional Huggins closed population models and a recent nonlinear extension of Huggins models – vector generalized additive models (VGAMs) – to estimate abundance of age-1 fish. Both model types suggested similar yearly age-1 abundance estimates, which varied from 163 in 2017 to 3,839 in 2010, but the VGAMs provided more direct interpretation for factors that might affect capture probability (e.g., sampling effort, temperature, fish length). This study indicates that the Altamaha River Atlantic Sturgeon population has remained relatively stable over the past decade, and provides a long-term baseline which will better allow managers to assess the effects of either future restoration actions or environmental disturbances on the population.</sup>

Frontiers in Ecology and the Environment. doi:https://doi.org/10.1002/fee.2695 \| Abstract	December 2023	Fisheries and aquaculture provide food and economic security, especially in the developing world, but both face challenges from infectious disease. We approach disease management through a structured-decision-making perspective. For both wild fisheries and aquaculture, management objectives generally aim to mitigate the severity and economic burden of disease outbreaks. In wild fisheries, options include regulating harvests, reducing system connectivity, and habitat conservation or improvement. In aquaculture, options include using pharmacological treatments, biocontrol strategies, bio-secure facilities and controlling density or increasing disease resistance through selective breeding. Developing and implementing disease-management strategies involve considering uncertainties and balancing competing stakeholder interests and risk tolerances; therefore, management strategies have tended to vary greatly depending on each unique situation. Although a transferable multipurpose solution to managing disease is unlikely for diverse fisheries and aquaculture enterprises, we suggest a path forward that could be broadly relevant to decision makers facing issues related to disease.

Annual Meeting of the GA Chapter of the American Fisheries Society. Augusta, GA. Jan 28-30.	January 2020	We used generalized linear models to assess habitat characteristics (e.g., substrate, habitat type, vertical relief, and/or sessile organisms) as useful predictors of Gag Grouper presence. Our preliminary results indicate that the probability of Gag Grouper occurrence is highest in habitats with fragmented bottom, higher latitudes, and greater depths.

Annual Meeting of the American Fisheries Society. Virtual. Sept. 14-25	August 2020	The Gag Grouper (<i>Mycteroperca microlepis</i>) is a popular recreationally and commercially targeted fish found along the continental shelf of the United States and Mexico., but relatively little is known about the kinds of reefs they use. We used information theoretic approaches to evaluate the habitat features with which gag was most frequently associated. Results indicated that gag occourence was positively related to percent rock coverage, maximum vertical relief, latitude, and depth. The
Alvarez G., D. Gandy, B. Irwin, C. Jennings, and A. Fox. 2021. Using Video Surveys to Examine the Effect of Habitat on Gag Occurrence. Florida Chapter of the American Fishery Society Virtual Meeting.	April 2021	The economically important Gag (<i>Mycteroperca microlepis</i>) fishery was declared overfished in the Gulf of Mexico in 2009. Although Gag are no longer overfished in the Gulf of Mexico, fisheries managers are concerned that stocks may not be recovering. Limited information on life history and habitat use contributes uncertainty about the long-term effectiveness of current management strategies in aiding recovery. Our objective was to identify habitat characteristics important to Gag, and thei
