| Summary: | Wildlife conservation requires timely information on the availability and use of key habitats and resources by a species. Among large terrestrial carnivores in North America, grizzly bears (Ursus arctos) are experiencing substantial reductions in range and population size due to habitat loss and anthropogenic activities. To support grizzly bear conservation, this research will quantify the impacts of anthropogenic disturbance and habitat characteristics on grizzly bear habitat selection for an essential seasonal resource, buffaloberry (Sheperdia canadensis). Using grizzly bear telemetry data across southern British Columbia, Canada, this research first develops a resource selection function to predict buffaloberry selection based on the influence of disturbance and habitat characteristics. Grizzly bear recursive movements were then quantified using a revisitation analysis to test competing hypotheses related to the influence of buffaloberry availability, resource availability and disturbance conditions on ... |
