Abstract: Understanding the consequences of anthropogenic change for migratory species is challenging because although they have evolved to cope with environmental uncertainty, migrants still rely on predictable relationships within and among habitats to make informed decisions. Calidris shorebirds rely on ephemeral wetlands during northward migration through mid-continental North America, where favorable habitat conditions are annually and regionally unpredictable and increasingly altered by land-use change. During spring 2013 and 2014, we assessed Calidris habitat use in the Rainwater Basin (RWB) and the Prairie Pothole Region (PPR) at both local and landscape scales. Although anthropogenic change has altered...

In collaboration with the University of Missouri and Iowa State University, this project advanced efforts to understand and accommodate uncertainty by applying to Missouri River sturgeon population dynamics the tools of multi-scale climate models and hierarchical Bayesian modeling frameworks, linking models for system components together by formal rules of probability. While a complete climate prediction may be intractable at this time -- for instance, the climate projections may not incorporate land use changes and solar fluctuations into the boundary conditions -- we proposed a framework to quantify known uncertainty that is also flexible enough to adapt to advances in climate predictions. A key advantage of the...

Snowshoe hares are the primary food source of the federally threatened Canada lynx. In western Montana for example, snowshoe hare make up 96% of lynx diet. In fact, hares are critical players in forest ecosystems because most carnivores prey on them. The main way that snowshoe hares escape predation is through camouflage. In response to changes in day length, snowshoe hares molt seasonally, changing color from brown to white in the winter to blend in with the snowfall and hide from predators. However, due to shorter snow seasons caused by recent changes in climate, snowshoe hares are turning white before it snows, making them more visible to predators. Because 21 other species around the world also undergo these...

Climate change has emerged as a key environmental concern of the 21st century and a major challenge for land and wildlife managers. Although scientists have made tremendous progress in predicting the impact of climate change on a regional and global scale, drilling down such projections to a locally applicable form has been difficult. A major project of the US Geological Survey's (USGS) Southwest Biological Science Center (SBSC), funded by the USGS National Climate Change and Wildlife Science Center (NCCWSC), drew on the work of an interdisciplinary team of scientists to help close the gap between theory and practical application in the arid southwestern U.S. Climate change in this region is predicted to be extreme,...
