We live in a fast-changing human-dominated world, where humans efficiently outclass other species in competing for resources and substantially modify the environment in several ways. Despite a certain recovery of their former range also due to recent urbanization and countryside abandonment, large carnivores in Europe are still far from coexisting peacefully with humans. Large carnivores are wide ranging species, with large home ranges and long dispersal distances, therefore one resource emerges to be particularly disputed with humans: space. Humans play a relevant role in shaping carnivores’ spatial patterns, not only by directly affecting their survival through hunting or lethal control, but also substantially modifying the landscape, thus, directly influencing habitat quality. The project  I am currently pursuing aims at a better understanding of the brown bear (Ursus arctos) space use patterns at different scales. This study will be mainly conducted on GPS and VHF telemetry locations of Dinaric brown bears collected in Croatia. Data will be analyzed using some of the most cutting-edge techniques in spatial ecology, such as Brownian bridge movement models, resource and step selection functions (RSFs and SSFs) to study home range size and overlap and resource selection at different spatio-temporal scales. Knowledge on bear space use and resource selection will be used to determine which habitat features are linked to the movement of individuals. This approach will offer a promising basis for assessing landscape connectivity, aimed at identifying transboundary areas that are strategic for maintaining population gene flow and prevent future spatial segregation that might jeopardize the Dinaric brown bear population.
