Road networks provide several benefits to human societies; however, they are also one of the major drivers fragmentation and habitat degradation. Their negative effects include wildlife-vehicle collisions which associated with increased barrier effects, restricted gene flow, local extinction risk. Large carnivores, such as brown bear ( Ursus arctos ), vulnerable road mortality while put safety ...

The skull of a small, young adult grizzly bear was discovered in the course of archaeological excavation of an early historic Eskimo house in northern Labrador. This discovery confirms the rumoured presence of Ursus arctm in Labrador in the eighteenth and nineteenth centuries. It is suggested that the Labrador grizzly represents an eastward extension of the barren-ground grizzly population acro...

We reanalysed the spatial structure of the Scandinavian brown bear (Ursus arctos) population based on multilocus genotypes. We used data from a former study that had presumed a priori a specific population subdivision based on four subpopulations. Using two independent methods (neighbour-joining trees and Bayesian assignment tests), we analysed the data without any prior presumption about the s...

We present a new paradigm for understanding habituation and the role it plays in brown bear (Ursus arctos) populations and interactions with humans in Alaska. We assert that 3 forms of habituation occur in Alaska: bear-to-bear, bear-to-human, and human-to-bear. We present data that supports our theory that bear density is an important factor influencing a bear's overt reaction distance (ORD); t...
