Identifying the risk regions of house break‐ins caused by Tibetan brown bears (Ursus arctos pruinosus) in the Sanjiangyuan region, China

Ecology and Evolution, 2019
Damage to homesteads by brown bears (Ursus arctos) has become commonplace in Asia, Europe, and the Americas. Science‐based solutions for preventing damages can contribute to the establishment of mechanisms that promote human–bear coexistence. We examined

A meta-analysis of ungulate predation and prey selection by the brown bear Ursus arctos in Eurasia

Mammal Research, 2018
At the biogeographic scale, spatial variation in diets may reflect not only the ecological flexibility of carnivore feeding habits, but also evolutionary adaptations of different populations within a species. We described the large-scale pattern in brown

Spatiotemporal depredation hotspots of brown bears, Ursus arctos, on livestock in the Pyrenees, France

Biological Conservation, 2019
One of the main factors limiting the acceptance of large carnivores is livestock depredation. Reducing damages on livestock requires understanding how depredation varies in space and time.

Winter insomnia: How weather conditions and supplementary feeding affect the brown bear activity in a long-term study

Global Ecology and Conservation, 2019
Climate change and anthropogenic food subsidies affect wildlife everywhere in the world. We used a 30-year set of data on winter observations of brown bear Ursus arctos to investigate the effects of weather and supplementary feeding on bear winter ...

Alaskan brown bears (Ursus arctos) aggregate and display fidelity to foraging neighborhoods while preying on Pacific salmon along small streams

Ecology and Evolution, 2018
The interaction between brown bears (Ursus arctos) and Pacific salmon (Oncorhynchus spp.) is important to the population dynamics of both species and a celebrated example of consumer‐mediated nutrient transport. Yet, much of the site‐specific information
