Sixty seven serum samples collected from 43 European brown bears (Ursus arctos) from Croatia were tested for < or = 31 serum chemistry parameters. Results were grouped and compared by bears origin (method of capture), sex, age, mass, and season sampled. Greatest differences were found between captive and free-living bears, and minor differences were found when sex, age, mass, or season of sampl...

Models for the development of species distribution in Europe typically invoke restriction in three temperate Mediterranean refugia during glaciations, from where recolonization of central and northern Europe occurred. The brown bear, Ursus arctos, is one of the taxa from which this model is derived. Sequence data generated from brown bear fossils show a complex phylogeographical history for wes...

Knowledge about the connectivity among natural populations is essential to identify management units for effective conservation actions. Conservation-minded has led recovery of large carnivore in northern Europe, possibly restoring between two separated, but expanding brown bear (Ursus arctos) on Scandinavian peninsula west and Karelia, a part Eurasian population, east. The degree these been po...

The cave bear, Ursus spelaeus, represents one of the most frequently found paleontological remains from the Pleistocene in Europe. The species has always been confined to Europe and was contemporary with the brown bear, Ursus arctos. Relationships between the cave bear and the two lineages of brown bears defined in Europe, as well as the origins of the two species, remain controversial, mainly ...
