Integrated distribution modeling resolves asynchrony between bat population impacts and occupancy trends through latent abundance Integrated distribution modeling resolves asynchrony between bat population impacts and occupancy trends through latent abundance

Monitoring populations is challenging for cryptic species with seasonal life cycles, where data from multiple field techniques are commonly collected and analyzed as multiple lines of evidence. Data integration can provide comprehensive inferences while improving accuracy, precision, and scope but faces challenges in modeling misaligned resolutions and observational uncertainties. We...

Ecological scenarios: Embracing ecological uncertainty in an era of global change Ecological scenarios: Embracing ecological uncertainty in an era of global change

Scenarios, or plausible characterizations of the future, can help natural resource stewards plan and act under uncertainty. Current methods for developing scenarios for climate change adaptation planning are often focused on exploring uncertainties in future climate, but new approaches are needed to better represent uncertainties in ecological responses. Scenarios that characterize how...

Native Yellowstone cutthroat trout Oncorhynchus virginalis bouvieri growth and survival in a headwater stream primarily driven by warming stream temperatures, with non-native brown trout Salmo trutta posing an additional threat to survival Native Yellowstone cutthroat trout Oncorhynchus virginalis bouvieri growth and survival in a headwater stream primarily driven by warming stream temperatures, with non-native brown trout Salmo trutta posing an additional threat to survival

Warming rivers and interactions with non-native species impact salmonid species globally. Understanding how hydroclimatic conditions synergistically and independently interact with non-native species is critical for effectively managing salmonids into the future. We used a 10-year mark–recapture dataset to assess how native Yellowstone cutthroat trout (YCT) Oncorhynchus virginalis...

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...

USGS Chronic Wasting Disease Research at NOROCK

Chronic wasting disease (CWD) is a growing management issue in the U.S. and has been detected in 36 states as of April 2025, including many western states. There is no cure or vaccine for CWD, and the disease threatens economically important animals like elk and deer. NOROCK scientists have taken a multi-pronged approach to develop actionable science including 1) evaluating CWD management options...
