USGS research into environmental stressors (e.g., climate, drought, floods, wildland fire) and anthropogenic stressors (e.g., energy production, urban encroachment, water abatement) provides managers with information to reduce or eliminate impacts from stressors to fish and wildlife populations and advances our understanding of the efficacy of conservation and adaptation actions to mitigate land-use and climate change impacts on sensitive species.

Mesocarnivore Survey of Lassen Volcanic National Park, Klamath Network, 2017-2018 (ver. 2.0, April 2022) Mesocarnivore Survey of Lassen Volcanic National Park, Klamath Network, 2017-2018 (ver. 2.0, April 2022)
Remote camera stations were set up in Lassen Volcanic National Park from August to October 2017 and June to September 2018 to document occurrence of mesocarnivores and other wildlife. 126 cameras were set up at 32 primary sampling units (clusters of two to four cameras) throughout the park. Random locations for primary sampling units were chosen using a 3-km sampling grid over the park...
Mesocarnivore Survey of Whiskeytown National Recreation Area, Klamath Network, 2018-2019 Mesocarnivore Survey of Whiskeytown National Recreation Area, Klamath Network, 2018-2019
Remote camera stations were set up in Whiskeytown National Recreation Area from October 2018 to January 2019 to document occurrence of mesocarnivores and other wildlife. Forty-five single-camera sampling stations were setup throughout the park. Camera locations were chosen based on the Klamath Monitoring Network vegetation plots. The dataset contains all species observed within the study...

Remote camera stations were set up in Oregon Caves National Monument and Preserve from February through April 2017 to document occurrence of mesocarnivores and other wildlife. Fifteen cameras were set up at four primary sampling units (clusters of three to four cameras) throughout the park. Random locations for primary sampling units were chosen using a 3-km sampling grid over the park...
Predicted Calving and Post-calving Season Resource Use of the Porcupine Caribou Herd During 2012–2018 With Future Projections for the 2030s, 2040s, and 2050s Predicted Calving and Post-calving Season Resource Use of the Porcupine Caribou Herd During 2012–2018 With Future Projections for the 2030s, 2040s, and 2050s
This dataset contains rasters and polygon shapefiles related to predicted resource use of the Porcupine Caribou Herd (PCH) during the calving (26 May-10 June) and post-calving (11-30 June) seasons in Alaska and the Yukon Territory. Resource selection was analyzed for each season using random forest models, which compared female caribou GPS collar locations (2012-2018) to available...

Through the North American Bat Monitoring Program, Bat Conservation International and U.S Geological Survey (USGS) provided technical and science support to assistance in U.S. Fish and Wildlife Service Species Status Assessment ("SSA") for the northern long-eared bat (Myotis septentrionalis), little brown bat (Myotis lucifugus), and tri-colored bat (Perimyotis subflavus). USGS...

Fatty acid profiles of feeding and fasting bears: Estimating calibration coefficients, the timeframe of diet estimates, and selective mobilization during hibernation Fatty acid profiles of feeding and fasting bears: Estimating calibration coefficients, the timeframe of diet estimates, and selective mobilization during hibernation
Accurate information on diet composition is central to understanding and conserving carnivore populations. Quantitative fatty acid signature analysis (QFASA) has emerged as a powerful tool for estimating the diets of predators, but ambiguities remain about the timeframe of QFASA estimates and the need to account for species-specific patterns of metabolism. We conducted a series of...

Utah prairie dog population dynamics on the Awapa Plateau: Precipitation, elevation, and plague Utah prairie dog population dynamics on the Awapa Plateau: Precipitation, elevation, and plague
Utah prairie dogs (UPDs, Cynomys parvidens) are colonial, herbivorous rodents listed under the Endangered Species Act as threatened. Little is known about UPD population dynamics at higher elevations in the species’ range. From 2013 through 2016, we studied UPDs on five colonies at 2,645 to 2,873 m elevation on the Awapa Plateau, Utah, USA. Primary production increases with precipitation...

Small mammal shooting as a conduit for lead exposure in avian scavengers Small mammal shooting as a conduit for lead exposure in avian scavengers
Lead (Pb) exposure is a widespread wildlife conservation threat. Although commonly associated with Pb-based ammunition from big-game hunting, small mammals (e.g., ground squirrels) shot for recreational or pest-management purposes represent a potentially important Pb vector in agricultural regions. We measured the responses of avian scavengers to pest-shooting events and examined their...

Acoustic interaction between a pair of owls and a wolf Acoustic interaction between a pair of owls and a wolf
During summer 2019, we recorded an apparent vocal interaction, lasting just under 4 min, between a pair of Great Horned Owls (Bubo virginianus) and a gray wolf (Canis lupus) in Yellowstone National Park. To our knowledge, this is the first report of such an acoustic interaction in the scientific literature. The increased use of passive acoustic recorders, which record spontaneous...

Native mammals lack resilience to invasive generalist predator Native mammals lack resilience to invasive generalist predator
Invasive predators have caused catastrophic declines in native wildlife across the globe. Though research has focused on the initial establishment, rapid growth, and spread of invasive predators, our understanding of prey resilience to established invasive predators remains limited. As a direct result of invasive Burmese pythons (Python molurus bivittatus), medium- to large-bodied native...

Estimates of abundance and harvest rates of female black bears across a large spatial extent Estimates of abundance and harvest rates of female black bears across a large spatial extent
American black bears (Ursus americanus) are an iconic wildlife species in the southern Appalachian highlands of the eastern United States and have increased in number and range since the early 1980s. Given an increasing number of human-bear conflicts in the region, many management agencies have liberalized harvest regulations to reduce bear populations to socially acceptable levels...
