Climate change is causing species to shift their phenology, or the timing of recurring life events such as migration and spawning, in variable and complex ways. This can potentially result in mismatches or asynchronies in food and habitat resources that negatively impact individual fitness, population dynamics, and ecosystem function. Numerous studies have evaluated phenological shifts in terrestr

Each year, plants and animals undergo certain life cycle events, such as breeding or flowering. These phenological events are linked to weather and climate, and as temperature and precipitation patterns have changed, some spring events are occurring earlier. These changes in plant phenology can have cascading effects on wildlife such as elk, moose, and mule deer, which depend on plants for food. I

Winter conditions have changed substantially in the Great Lakes region over the last 50 years, with the region experiencing rising temperatures, declining lake ice cover, and increased lake-effect snow. These changes have direct implications for economically important wildlife, such as deer and waterfowl. Deer hunting alone contributes $482 million annually to Wisconsin’s economy. The goal of th

This project identified priority areas in the Columbia Plateau Ecoregion to focus on for riverine and riparian habitat conservation. The project’s products are tailored towards the Arid Lands Initiative (ALI) conservation goals and objectives and provide the foundation for adaptation to a changing climate. We adopted a “zoned” approach to identifying focal areas, connectivity management zones, and

Moose and caribou are two very important animals to both subsistence and sport hunting economies in Alaska. Their survival and reproduction is dependent on sufficient winter habitat and food sources, which may be threatened by climate change. During the winter, caribou eat lichens (organisms made up of algae and fungus) that grow on the snow-covered ground. Lichens will likely have a complex resp

Changing temperature and precipitation patterns in the South Central U.S are already having an impact on wildlife. Hotter and drier conditions are prompting some species to move in search of cooler conditions, while other species are moving into warmer areas that were once unsuitable for them. These changes in the distribution of wildlife populations present challenges for wildlife managers, hunte

Native to the southwestern U.S. and northwestern Mexico, the desert bighorn sheep is known for its ability to adapt to harsh, arid environments. However, this does not mean the species is immune to the effects of drought. In fact, the fragmented and isolated distribution of the desert mountain ranges that they inhabit means that they can’t follow distant rain storms without traversing broad valley

The antelope-like pronghorn is the fastest land animal in North America and has the longest land migration in the continental U.S—in fact, the species has been dubbed “the true marathoners of the American West”. While pronghorns are numerous in parts of their range, such as Wyoming and northern Colorado, they are endangered in others, such as the Sonoran Desert. In the arid Southwest, pronghorn p

Species that inhabit the arid Southwest are adapted to living in hot, dry environments. Yet the increasing frequency and severity of drought in the region may create conditions that even these hardy species can’t survive. This project examined the impacts of drought in the southwestern U.S. on four of the region’s iconic species: desert bighorn sheep, American pronghorn, scaled quail, and Rio Gran

Caribou populations in Alaska are important to both resident and visiting hunters and provide a large source of income for commercial operators and local communities who provide services to these hunters. Caribou have also provided a traditional staple food source for native Alaskan communities. Moreover, caribou are important prey for wolves and bears and their health and population size impact t
