Mating-related movements of male brown bears on the periphery of an expanding population

摘要: Abstract Use of habitat and resources large carnivores living at the expansion front a population can differ considerably from those in core areas. Using GPS (global positioning system) telemetry, we studied movements male brown bears northwest edge Alpine–Dinaric–Pindos Slovenia Italy, 2005–08. Because there was steep gradient female densities periphery females occurred only small portion area used by males, could test how distribution breeding affected spatial bears. The home-range size males our study inversely related to densities. During mating season observed directed movement with low toward higher Our observations suggest that this strategy allows even population, where no we...
