Wildlife management and conservation is challenged by public perceptions and fear of carnivores in communities living in close proximity to wild habitats, where large carnivores occur. Fear of carnivores influences peoplechr('39')s attitudes towards wild animals, further exacerbating the problems associated with effective conservation and management of wildlife.

متن کاملAncient DNA analysis reveals divergence of the cave bear, Ursus spelaeus, and brown bear, Ursus arctos, lineages
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 ...
متن کاملWhich future for the French Pyrenean brown bear (Ursus arctos) population? An approach using stage-structured deterministic and stochastic models.
The Pyrenean brown bear (Ursus arctos) population is considered as one of the most seriously threatened with extinction in Western Europe. To assess its viability and possible needs of augmentation, we develop deterministic and stochastic stage-structured demographic models. The deterministic model reveals that a bear population cannot have a high annual growth rate and is particularly sensitiv...
متن کاملGenetic relationships of extant brown bears (Ursus arctos) and polar bears (Ursus maritimus).
Polar bears (Ursus maritimus) and brown bears (Ursus arctos) are closely related species for which extensive mitochondrial and nuclear phylogenetic comparisons have been made. We used previously published genotype data for 8 microsatellite DNA loci from 930 brown bears in 19 populations and 473 polar bears in 16 populations to compare the population genetic relationships of extant populations o...
