An energetic tradeoff best explains parturition timing in grizzly bears An energetic tradeoff best explains parturition timing in grizzly bears
Timing of grizzly bear (Ursus arctos) parturition during hibernation has been explained by ancestral traits (delayed implantation, altricial young, obligate maternal denning), but the ultimate driver underlying precise timing has not been fully explored. Capitalizing on an observed latitudinal increase in denning duration among four populations in interior North America, we tested two...
Annual grass invasion is transforming the sagebrush biome’s songbird communities Annual grass invasion is transforming the sagebrush biome’s songbird communities
Novel stressors like climate change and biological invasions alter ecological communities, resulting in changes to ecosystem services and biodiversity (that is, ecological transformation). Most ecological transformation research focuses on plants, but animals are likely affected by and plausibly mediate the extent, impact, and pace of transformations. In western North America, where...
Status assessment of peregrine falcons in North America using integrated population models Status assessment of peregrine falcons in North America using integrated population models
Species status assessments require an understanding of underlying population dynamics and important drivers of species demography. Large-scale assessments can be difficult due to challenges collating data obtained through different methods and different sources at multiple scales. Integrated population models (IPMs) provide a unified framework to combine multiple data sources and jointly...

Wyoming Landscape Conservation Initiative (WLCI) research at NOROCK
The Wyoming Landscape Conservation Initiative (WLCI) addresses the impacts of land-use and habitat changes on Southwest Wyoming’s natural resources. This long-term project involves partners from 12 Federal, State, and local natural resource agencies, as well as non-governmental organizations. NOROCK scientists, partners, and scientists from other USGS centers conduct integrated research to support...
North American Bat Monitoring Program (NABat)
Bats are essential contributing members of healthy, functioning ecosystems. They perform numerous ecosystem services like insect pest control and plant pollination, and provide enormous economic benefits through ecotourism, medical research, and novel biotechnologies. North American bats face unprecedented threats including habitat loss and fragmentation, white-nose syndrome, and wind energy...
USGS Science Syntheses for Public Lands Management
Scientific information is fundamental to understanding how proposed actions on public lands may impact the environment. Development of new science is occurring at rates that can make it challenging for biologists, resource managers, decision makers, private landowners, and other stakeholders to ensure they are using up-to-date, high-quality science information to inform their decisions. Further...
