jeniseensis Ognev, 1924sibiricus J. E. Gray, 1864 The East Siberian brown bear (Ursus arctos collaris) is a population or subspecies of brown bear which ranges from eastern Siberia, beginning at the Yenisei river, north to the Arctic Circle, as far as Trans-Baikaliya, the Stanovoy Range, the Lena River, Kolyma and generally throughout Yakutia and the Altai Mountains.

European brown bears, for example, as they inhabit a continental area far smaller than Siberia or Russia, are generally warier of people, as they are, more or less, persecuted and feared throughout their range.

Both literally and figuratively, European bears are "surrounded" by humans and their dogs on all sides, on an already-cramped continent, a harsh reality which dictates their very movements and behaviours.

Through digging, they will periodically find and hunt ground squirrels, moles, and different wild rodent species, among other terrestrial mammals.

[2] The Siberian brown bear is, reportedly, more actively carnivorous than other Ursus arctos subspecies;[4] this may possibly be due to the ruggedness or the freezing winters of their home range stimulating them to consume more protein and fats before the first snowfall.
