Predictors of brown bear predation events on livestock in the Romanian Carpathians
Conservation Science and Practice, 2023 Livestock depredation by brown bears is one of the main source of human–wildlife conflict in rural Eastern Europe. Thus, identifying environmental and anthropogenic drivers of human–bear conflict, and developing spatial predictions for predation ...

Biomechanical consequences of rapid evolution in the polar bear lineage. [PDF]
PLoS ONE, 2010 The polar bear is the only living ursid with a fully carnivorous diet. Despite a number of well-documented craniodental adaptations for a diet of seal flesh and blubber, molecular and paleontological data indicate that this morphologically distinct ...
