The Alabama Cooperative Fish and Wildlife Research Unit, est.1936, is a partnership among Alabama Department of Conservation and Natural Resources, Auburn University, the U.S. Geological Survey, the U.S. Fish and Wildlife Service, and the Wildlife Management Institute.
The Alabama Cooperative Wildlife Research Unit was established on the Auburn University campus in 1936. Among the first ten Units, it was established to conduct wildlife research and promote the education of wildlife professionals for the southeastern region, Alabama, Georgia, northern Florida and eastern Mississippi. The Alabama Cooperative Fisheries Unit was established at Auburn in 1966 with a similar role. The Units were combined in 1984 to form the Alabama Cooperative Fish and Wildlife Research Unit.

The Alabama Unit has identified four areas in which to concentrate its research efforts: 1) determining the effects of forest management practices on wildlife populations, 2) investigating the ecology and management of riverine systems, 3) investigating the status, life history, habitat requirements, and population dynamics of species of conservation concern, and 4) investigating the ecology and management of fish and wildlife on landscape scales. The Alabama Cooperative Fish and Wildlife Research Unit staff teach graduate level course in applied fisheries and wildlife science. Coursework offered by unit scientists focus on quantitative ecology and management science.

Prioritization of areas for open pine ecosystem restoration in the Southeastern United States: All Species Prioritization of areas for open pine ecosystem restoration in the Southeastern United States: All Species
We used NLCD 2011, SSURGO, and SEGAP data to map the density of desired resources for open pine ecosystems and six focal species of birds and 2 reptiles within the historic range of longleaf pine east of the Mississippi River. Binary rasters were created of sites with desired characteristics such as land form, hydrology, land use and land cover, soils, potential habitat for focal species...
Survey protocols drive heterogeneity in occupancy estimates that cannot be standardized using post hoc analyses Survey protocols drive heterogeneity in occupancy estimates that cannot be standardized using post hoc analyses
Site occupancy models are widely used to estimate species distributions from presence–nondetection data, yet for mobile animals, the true proportion of sites occupied varies in time. Thus, true occupancy and estimates generated from different protocols are affected by temporal characteristics of survey design.Here we tested whether we could standardize occupancy estimates across...

Spatially concentrating logging could mitigate climate-magnified fragmentation risks to a globally endangered bird Spatially concentrating logging could mitigate climate-magnified fragmentation risks to a globally endangered bird
1. Rising timber demand is transforming forest structure globally, profoundly affecting biodiversity and climate resilience. Logging-driven fragmentation is potentially a major driver of biodiversity loss in production landscapes, yet its interactions with escalating climate stressors remain poorly understood. 2. We combine two decades of Landsat-derived habitat metrics with 29,000...

Comparing surgery time and short-term incision healing for Largemouth Bass using smooth- and barbed-absorbable sutures Comparing surgery time and short-term incision healing for Largemouth Bass using smooth- and barbed-absorbable sutures
Objective Barbed sutures have become increasingly favored over traditional smooth sutures in human medicine but remain understudied in fisheries biotelemetry applications. Our objectives were to (1) compare surgery time and recovery time for Largemouth Bass Micropterus nigricans when using smooth- versus barbed-absorbable sutures to close the incisions and (2) compare the short-term...

Overwinter and prespawning movements by a vulnerable freshwater pelagophilic minnow Overwinter and prespawning movements by a vulnerable freshwater pelagophilic minnow
The decline of pelagophil minnows is related to river fragmentation across the southern Great Plains landscape. Because we know little about pelagophil movement patterns and timing, we aimed to quantify the movements of the vulnerable Arkansas River shiner (ARS) during the winter (November–March) and prespawning (April–June) seasons. We tagged 4233 ARS using visible implant elastomer...

Thinking beyond the closure assumption: Designing surveys for estimating biological truth with occupancy models Thinking beyond the closure assumption: Designing surveys for estimating biological truth with occupancy models
Occupancy models estimate distributions of imperfectly detected species, but violations of the closure assumption can bias results. However, researchers working with mobile animals may find it impossible to eliminate such violations. Here, we tested the hypothesis that occupancy models fit to realistic sampling data can generate unbiased occupancy estimates for an itinerant Wood Thrush...

Designing count-based studies in a world of hierarchical models Designing count-based studies in a world of hierarchical models
Advances in hierarchical modeling have improved estimation of ecological parameters from count data, especially those quantifying population abundance, distribution, and dynamics by explicitly accounting for observation processes, particularly incomplete detection. Even hierarchical models that account for incomplete detection, however, cannot compensate for data limitations stemming...

Passive acoustic monitoring and convolutional neural networks facilitate high-resolution and broadscale monitoring of a threatened species Passive acoustic monitoring and convolutional neural networks facilitate high-resolution and broadscale monitoring of a threatened species
Population monitoring is an essential component of biodiversity conservation and management, but low detection probabilities for rare and/or cryptic species makes estimating abundance and occupancy challenging. Passive acoustic monitoring combined with machine learning algorithms represents a potential path forward to effectively and efficiently monitor the occurrence of rare vocalizing...

Code for Meta-analysis and review of catch-and-release fish mortality estimates Code for Meta-analysis and review of catch-and-release fish mortality estimates
Catch-and-release angling in flowing waters is widespread, but estimates of how many released fish die afterward vary, and it is unclear how much of that spread reflects biology as opposed to how each study was designed and how long it watched its fish. This repository holds the single R script behind the synthesis addressing that question: it compiles published delayed hooking-mortality...
