Assimilated diet patterns of American black bears in the Sierra Nevada and western Great Basin, Nevada, USA
In western Nevada, USA, the American black bear (Ursus americanus) coexists with humans and increasing urban sprawl. Hotels, casinos, restaurants, and homeowners dispose large quantities of high-protein, calorie-rich foods, often in unsecured waste containers.

Roads are influential through their direct footprint and facilitating human access; however, their influence can be mitigated. Here, we review the scientific literature on the relationship between grizzly bears (Ursus arctos), […]
Primarily resident grizzly bears respond to late-season elk harvest
Autumn ungulate hunting in the Greater Yellowstone Ecosystem carries the risk of hunter-grizzly bear (Ursus arctos) conflict and creates a substantial challenge for managers. For Grand Teton National Park, Wyoming, USA, a key information need is whether increased availability of elk (Cervus canadensis) carcasses during a late autumn (Nov-Dec) harvest within the national park attracts […]
