The grizzly bear population inhabiting the GYE is of national and international interest. Although this population has increased in size and extent in recent years (Eberhardt et al. 1994, Eberhardt 1995, Boyce et al. 2001, Schwartz et al. 2002), isolation from other grizzly bear populations and continuing human development along its geographic margins justify continued concern about its future....

Increasing global demands have resulted in widespread proliferation of resource extraction. Scientists are challenged to develop environmental mitigation strategies that meet societal expectations of resource supply, while achieving minimal disruption to sensitive "wilderness" species. We used GPS collar data from a 9-year study on grizzly bears (Ursus arctos) (n = 18) in Alberta, Canada to ass...

Past research indicates that whitebark pine seeds are a critical food source for Threatened grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem (GYE). In recent decades, whitebark pine forests have declined markedly due to pine beetle infestation, invasive blister rust, and landscape-level fires. To date, no study has reliably estimated the contribution of whitebark pine seeds to ...
