Local climate determines vulnerability to camouflage mismatch in snowshoe hares
Aim Phenological mismatches, when life-events become mistimed with optimal environmental conditions, have become increasingly common under climate change. Population-level susceptibility to mismatches depends on how phenology and phenotypic…
Predicting persistence of Rio Grande Cutthroat Trout populations in an uncertain future
The Rio Grande Cutthroat Trout Oncorhynchus clarkii virginalis (RGCT) occupies just 12% of its ancestral range. As the southernmost subspecies of Cutthroat Trout, we expect a warming climate to bring additional stressors to RGCT populations, such as…
Chemical immobilization in American black bears using a combination of nalbuphine, medetomidine, and azaperone
Safe and effective but unscheduled drug combinations are needed for wildlife immobilization in some jurisdictions. To this end, we evaluated a combination of nalbuphine HCl (40 mg/mL), medetomidine HCl (10 mg/mL), and azaperone tartrate (10…
Evaluation of translocation of black bears involved in human–bear conflicts in South-central Colorado
From 1995 to 1997, black bears (Ursus americanus) involved in conflicts with humans in southeastern Colorado, USA, were radiocollared, translocated, and monitored by the Colorado Division of Wildlife to evaluate translocation as a management tool for…
Diverse university students across the United States reveal promising pathways to hunter recruitment and retention
Declining participation in hunting, especially among young adult hunters, affects the ability of state and federal agencies to achieve goals for wildlife management and decreases revenue for conservation. For wildlife agencies hoping to engage…
Community confounding in joint species distribution models
Joint species distribution models have become ubiquitous for studying species-environment relationships and dependence among species. Accounting for community structure often improves predictive power, but can also affect inference on…
Urbanization impacts apex predator gene flow but not genetic diversity across an urban‐rural divide
Apex predators are important indicators of intact natural ecosystems. They are also sensitive to urbanization because they require broad home ranges and extensive contiguous habitat to support their prey base. Pumas (Puma concolor) can persist near…
Enhancing species distribution modeling by characterizing predator-prey interactions
Niche theory is a well-established concept integrating a diverse array of environmental variables and multispecies interactions used to describe species geographic distribution. It is now customary to employ species distribution models (SDMs) that…
Machine learning to classify animal species in camera trap images: applications in ecology
Motion-activated cameras (“camera traps”) are increasingly used in ecological and management studies for remotely observing wildlife and are amongst the most powerful tools for wildlife research. However, studies involving camera traps result in…
Improving the accessibility and transferability of machine learning algorithms for identification of animals in camera trap images: MLWIC2
Motion-activated wildlife cameras (or “camera traps”) are frequently used to remotely and noninvasively observe animals. The vast number of images collected from camera trap projects has prompted some biologists to employ machine learning algorithms…
