For more than a decade and a half, I have been part of effective collaborations with NOAA, USFWS, PIN, MDMR, UMO and hydropower companies to inform questions of passage for both adult and juvenile Atlantic salmon in the Penobscot River. Because no amount of research can move the species to recovery without influencing management actions, it is worthwhile to reflect, as a community of stakeholders, on the degree to which some research efforts have been integrated or ignored.

Little is known regarding the susceptibility of nongame fishes to tournament harvest. The goal of this study was to understand the susceptibility of catostomids to gigging tournament harvest within the Spavinaw-Eucha river-reservoir complex. To do this, we are seasonally sampling fixed sites within the reservoir, the perennial lower portion of the major tributary, the intermittent upper portion of the major tributary, two perennial tributaries, and five intermittent tributaries with a variety o

|
November 2023
|
In the Everglades, invasive Burmese pythons have dramatically reduced mammal populations. Similar responses to the cues of native predators and the invasive python indicate that cotton rats are unlikely to exhibit naiveté to this novel predator and may be pre-adapted to respond to this invader from their evolutionary experience with native snakes.

Fall lake surveys for larval Walleye (<i>Sander </i><i>vitreus</i>) show a decline in natural recruitment for populations in the northern third (Ceded Territory) of Wisconsin dating back to the early 1980s. Relationships between age-1 mortality and age-0 CPE show that mortality of age-1 Walleye was highly variable at low age-0 abundance. At high age-0 abundance, mortality of age-1 fish was consistently high, implying a compensatory relationship between age-0 abundance and age-1 Walleye mortalit

The Interior Population of trumpeter swans results from reintroductions beginning in the late 1960s, with initially modest goals of re-establishing several hundred pairs of breeding swans. Since that time, the Interior Population has grown dramatically with upwards of 25,000 individuals counted in the 2015 survey. Because very little is known about movement ecology of this reintroduced population, we have initiated a 4-year study across the Interior Population to answer basic questions about

Managers are interested in both factors influencing movement and survival estimates to identify the most logical periods and locations for stocking and/or to understand where stocking may be problematic (e.g., negative interaction with native fishes). However, studies have often focused on Rainbow Trout stocked into modified systems (e.g., tailwaters) and where harvest is high (e.g., put and take fisheries).

The Prairie Chub Machrybopsis australis is a pelagic-broadcast spawning cyprinid (i.e., pelagophil) endemic to the Red River basin and a species of greatest concern need in Oklahoma. The vulnerability of Prairie Chub to changes in flow alteration is thought to be largely attributed to its reproductive ecology. We evaluated hatch date related to discharge, and temperature conditions across the Red River basin.

|
The reproductive strategy of Prairie chub is common among prairie stream fishes and relies on adequate discharge for successful recruitment. Examining discharge requirements for Prairie chub can inform management regulations on water use that may have broader implications for this reproductive guild. We modeled Prairie Chub colonization and extinction probabilities in relation to flow regime metrics, while accounting for imperfect detection.

Beaver fundamentally modify stream morphology and hydrology by creating ponds and wetlands that serve as critical breeding habitat for a plethora of species. Over time, as fluctuations in pond quality and loss of pond habitat occurs, population persistence for species reliant on such habitat is dependent on the creation of new beaver ponds.

The lesser prairie-chicken (Tympanuchus pallidicinctus) is a prairie grouse that was once numerous throughout the southern Great Plains, particularly in the Sand Sagebrush Prairie Ecoregion of Kansas, Colorado, and Oklahoma. Our results suggest that anthropogenic disturbance has become increasingly prevalent since lesser prairie-chicken population peak and availability of habitat to support long-term population persistence has decreased.

Half of the world's coral reefs have been lost in recent decades, while climate change and local stressors threaten one-third of those remaining. This decline threatens the ecosystem services that reefs provide, including their value as habitat for fish. The regulatory programs that apply to coral reefs manage a wide variety of local stressors that include land-based sources of pollution.

Local management action that addresses coastal pollutants can directly improve and preserve healthy ecosystem functioning of coral reefs, thus mitigating the effects of climate change. However, effective decision making for reef resilience is not easy – it relies on a complex understanding of tipping points in water quality associated with coral health and decline. In response to needs identified by reef managers from Hawai'i and the Pacific region, we conducted a set of systematic literature r

Local management action to address land-based stressors on coral reefs can improve reef health and mitigate the effects of globally increasing sea surface temperatures. Coastal development and runoff lead to sedimentation, which directly impacts coral demography and the ecosystem services that coral reefs provide. Decision making for reef resilience in the face of global and local stressors requires information on thresholds for land-and sea-based management action. In response to needs identif

|
October 2019
|
We provide a regional perspective on managing inland glacial lakes for climate change to guide the management of heterogeneous and interdependent fishery resources. We find that the integration of ecological, social, and economic data can be used to classify lakes into “priority levels”, which may in turn help planners make decisions about where to apply fisheries management tactics.

Poster presentation.
|

|
Wisconsin anglers prefer quality fisheries with moderate size-structure and catch rates regardless of species, but largemouth bass fishery characteristics are more important to non-residents than residents. In addition, bluegill are a major driver of angler choice and the retention of quality bluegill fisheries is essential to maintaining angler participation if climate changes results in regional declines in walleye fisheries.

We used the nest survival model in program MARK to estimate daily nest survival rates (DNS) as a function of colony location, year, within-season time trends, vegetation cover categories and height, and six weather covariates. In general DNS was low in all years, but the best year structure suggested 2017=2018, and 2019=2020. Year effects also varied by colony with higher DNS observed at nests with higher average vegetation height.

We developed a spatially-explicit formulation of Close-kin mark–recapture (CKMR) models that corrected for incomplete mixing by modifying kinship probabilities to incorporate sex-specific probability density functions of natal dispersal distances. We applied the model to panmictic and dispersal-limited population simulations and concluded with an example using Michigan’s 2021 harvest data of American black bears (<i>Ursus americanus</i>).

Close-kin mark–recapture (CKMR) is an abundance estimation method analogous to traditional mark–recapture that does not require recapture of individuals, but instead uses genetic marks to identify proportions of related individuals detected in a single sampling occasion (often through harvest). We used forward-in-time, individual-based simulations to evaluate the accuracy and precision of CKMR abundance estimates under different reproductive strategies (promiscuity, serial monogamy and polygamy

Knowledge of the timing and density of juvenile river herring as they leave freshwater lakes is essential for understanding within-lake mortality and for modeling populations across life stages. This effort will test a new method for monitoring and processing juvenile river herring emigration data using citizen scientists, and thus has the potential to not only increase data collection but continue to engage the public in river herring research and conservation.

|
July 2023
|
Using data from 195 geolocating devices we identified molt locations on pack ice in the Ross Sea for Adélie penguins during 2017-2019. From remotely sensed data were able to determine that sea ice concentration in the molt area during this study was lower than normal relative to the long-term trend.

|
August 2022
|
We used geolocating diver recorders attached to Adélie penguins from 2 breeding colonies on Ross Island, Antarctica to estimate molt timing and duration. Adélie penguins molt on sea ice in the ocean after breeding, and return rates of penguins to breeding colonies on Ross Island after molting and wintering are lower when sea ice concentration in molting areas is low. This suggests ocean conditions during the molting period might have important effects on penguin population trajectories.

This study assessed how connectivity for Lesser Prairie-Chickens on the Southern High Plains was potentially altered by landscape conversion that created a patch network. Our results suggest that there was a 31.5 km coalescence distance of the network (farthest nearest-neighbor distance), with as few as two leks being cutpoints within the network, meaning if these leks were abandoned, birds and associated habitat near the remaining leks may become isolated.

Effective conservation of at-risk species requires an understanding of trends in abundance over time, but in many cases the data necessary to estimate population trajectories are often quite noisy and incomplete. I used a hierarchical state-space model to estimate trends over time for 242 populations located in 62 core areas spread across the Pacific Northwest; approximately 60% of the core areas showed a decreasing trend over time, but only 5% of the core areas had significant declines.

|
May 2023
|
Chronic wasting disease (CWD) is unique among prion diseases in that it affects free-ranging host species and prions shed by the host remain infectious, and may contribute to further geographic spread of the disease. We describe here a method for extraction of prions from environmental matrices which are then amenable for detection by the real-time quaking induced conversion (RT-QuIC) assay.

|
August 2022
|
Adult Atlantic salmon endure a long upstream migration without feeding, entering freshwater in May-July to reproduce.We modelled the bioenergetic costs incurred by delayed fish under temperature regimes that would be encountered under a “no dam” (no delay) scenario versus one, two, three, or four dams.

|
January 2020
|
Passage delays expose upstream migrating fish to elevated water temperatures causing increased metabolic demand, but there currently exists no clear quantification of metabolic costs and fitness risks. Using temperature logging radio tags and a Distell Fish Fatmeter, we radio tagged, tracked, and measured 66 Atlantic salmon over two years on both the Penobscot and Kennebec Rivers.

We have developed methods of “coupled classification” in which statistical classification models are linked to ecological models of species abundance or occurrence. In this new framework, classification (e.g., species identification) takes into account the local structure of populations, communities and landscapes and does not assume that where a sample is collected is independent of the class structure of the population, as most current classification methods do.

|
January 2020
|
Impervious cover alters the hydrology, geomorphology, and water quality in streams resulting in impaired biotic assemblages; however, the variation in biotic responses among sites have received little attention. Here, we show that fish responses to impervious cover vary in different physiographic regions and with different reach-scale charactertistics within Massachusetts, suggesting that a one-size-fits-all solution to urban stream restoration is unlikely to be effective.

While research has focused on the effects of winter tick infestation on moose survival and reproduction, the stress response to ticks or any other potential stressor remains understudied. We used repeated fecal sampling of 116 radio-collared moose from 2017 to 2019 to quantify fecal glucocorticoid metabolites (fGCM). Preliminary analysis suggest winter tick load had a strong positive effect on fGCM levels, but snow depth, road density, and conifer forest coverage also positively influenced fGMC

Parasites have been documented to alter host behavior in ways that benefit the parasite's survival and transmission, especially when transmission occurs via predation. We used behavioral arenas to test how infected and non-infected snails responded to predation risk cues, and found that infected snails moved twice as far away as uninfected snails, which could have potential impacts on the dispersal of these parasites throughout the environment.

Monitoring fish and invertebrate resources is a vital component of conservation. Yet, organismal data alone are not enough. Data on relevant habitat are also critical to interpret native fish and invertebrate distribution patterns. Obtaining relevant habitat data across an entire state or region is a challenge given the broad geographic extent of aquatic resources and concurrent limitations in biologist time and budgets.

Bayesian continuous time models have been developed to estimate the true animal movement trajectory that underlies discretely recorded telemetry data, yet these models remain inaccessible and underutilized. To account for these transitions, we recognized a novel application of a recently developed machine learning method and incorporated it in the Bayesian continuous time modeling framework using data from a declining grassland bird, the lesser prairie-chicken (Tympanuchus pallidicinctus).

We are investigating the human (e.g., wastewater infrastructure, housing density) and biophysical (e.g., discharge, precipitation) controls on urban riverine dissolved organic carbon (DOC) across U.S. cities representing diverse geographies and urban contexts. A better understanding of human and biophysical controls on DOC across urban rivers will provide important information for carbon budgets and river management.

|
November 2022
|
Several studies report on puma diets in the arid regions of the southwestern United States within homogenously xeric locations, overlooking landscape diversity generated by riparian forests. Such habitat heterogeneity and corresponding prey diversity could influence puma habitat use, prey availability and diet composition. We examined puma diet in New Mexico, at sites representing riparian areas adjacent to the Rio Grande and xeric Chihuahuan Desert uplands.

November 2022
|
Man-made water sources have been developed for wildlife in arid regions since the mid 1900s. Although wildlife are generally considered to benefit from water development, there is very little known about how the provision of man-made water influences predator-prey dynamics. It is possible that the increased abundance of prey and or the habitat features surrounding man-made water sources increase predation risk by puma (Puma concolor). To examine this, puma diet data was compiled from seven stud
