Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument

Sarah L. Carroll, Elizabeth P. Flesch, Salix R. Scoresby, Emily Spencer et autres

Abstract Translocations have been widely used to restore and conserve bighorn sheep ( Ovis canadensis ) populations in North America. Some translocations have been successful, but many populations remain small and genetically isolated. Population structure can influence the viability and long‐term success …

Estimating GPS-based social aggregation metrics using collar data

William M. Janousek, Gavin G. Cotterill, Olivia J. Lobo, Eric K. Cole et autres

Understanding social aggregation patterns in ungulate herds is essential for gaining behavioral insights, optimizing resource use, reducing human-wildlife conflict, and managing disease risk. As chronic wasting disease is the preeminent disease-related threat to cervid populations in North America, knowledge of contact between …

The interplay of habitat quality and temperature shape demographic patterns of mule deer (Odocoileus hemionus) in North America

William M. Janousek, Aaron N. Johnston, Sarah L. Bullock, Sarah R. Dewey et autres

Mule deer (Odocoileus hemionus) are declining in abundance across their broad distribution in western North America. Identifying drivers of mule deer demography could inform habitat restoration. However, linking habitat quality to vital rates is challenging and often done indirectly using proxy metrics. …

Mountain goat declines in a protected, interior, native population

Tabitha A. Graves, William M. Janousek, Michael J. Yarnall, Jami J. Belt

Abstract A shifting climate poses threats to alpine‐adapted species including mountain goats. We used long‐term (12 years) citizen science monitoring data and Bayesian N‐mixture modeling to estimate population trends and drivers of population metrics among mountain goats in Glacier National Park (GNP). …

Informing adaptive management to reduce ungulate aggregations: A case study involving winter feeding of elk

William M. Janousek, Eric K. Cole, Sarah R. Dewey, Tabitha A. Graves

Abstract In the United States, wildlife managers are entrusted with preserving culturally and economically important ungulate populations in the face of the ongoing spread of chronic wasting disease (CWD). The U.S. Fish and Wildlife Service established an adaptive management plan to reduce …

Population and spatial dynamics of desert bighorn sheep in Grand Canyon during an outbreak of respiratory pneumonia

Clinton W. Epps, Brandon Holton, Ryan J. Monello, Rachel S. Crowhurst et autres

Introduction Terrestrial species in riverine ecosystems face unique constraints leading to diverging patterns of population structure, connectivity, and disease dynamics. Desert bighorn sheep (Ovis canadensis nelsoni) in Grand Canyon National Park, a large native population in the southwestern USA, offer a unique …

Recent and future declines of a historically widespread pollinator linked to climate, land cover, and pesticides

William M. Janousek, Margaret R. Douglas, Syd Cannings, Marion A. Clément et autres

The acute decline in global biodiversity includes not only the loss of rare species, but also the rapid collapse of common species across many different taxa. The loss of pollinating insects is of particular concern because of the ecological and economic values …

Avian species richness and abundance show stronger responses to bison grazing intensity than to ecosystem productivity

Danielle A. Fagre, William M. Janousek, Victoria J. Dreitz

Abstract Temperate grassland ecosystems are one of the most threatened ecosystems worldwide, and their loss endangers the grassland songbirds that rely upon them. This guild of birds has shown long‐term declines in North America. At the same time, American bison (Bison bison) …
