Spatiotemporal depredation hotspots of brown bears, Ursus arctos, on livestock in the Pyrenees, France
International audience One of the main factors limiting the acceptance of large carnivores is livestock depredation. Reducing damages on livestock requires understanding how depredation varies in space and time. The conservation of the brown bear (Ursus arctos) population in the Pyrenees offers a re...
