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

Magnitude of historical and expected changes of mammals' natural habitats in Eastern Eurasia based on the EEBIO (GLOBIO) modelling approach [PDF]

Праці Теріологічної школи, 2010
In 2005–2006 we developed first in Ukraine 65 GISs (ArcMap 9x) based on new experience using remote sensing data (1 km…25 m) of 1993–2005. The set of maps was used for wide analysis of historical and expected expansion of mammals in the post-soviet ...

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
