The role of human outdoor recreation in shaping patterns of grizzly bear-black bear co-occurrence
Species' distributions are influenced by a combination of landscape variables and biotic interactions with other species, including people. Grizzly bears and black bears are sympatric, competing omnivores that also share habitats with human recreationists. By adapting models for multi-species occupancy analysis, we analyzed trail camera data from 192 trail camera locations in and around Jasper ...
متن کاملGrizzly Bear Noninvasive Genetic Tagging Surveys: Estimating the Magnitude of Missed Detections
Sound wildlife conservation decisions require sound information, and scientists increasingly rely on remotely collected data over large spatial scales, such as noninvasive genetic tagging (NGT). Grizzly bears (Ursus arctos), for example, are difficult to study at population scales except with noninvasive data, and NGT via hair trapping informs management over much of grizzly bears' range. Consi...
متن کاملDiscovery of the Skull of a Grizzly Bear in Labrador
The skull of a small, young adult grizzly bear was discovered in the course of archaeological excavation of an early historic Eskimo house in northern Labrador. This discovery confirms the rumoured presence of Ursus arctm in Labrador in the eighteenth and nineteenth centuries. It is suggested that the Labrador grizzly represents an eastward extension of the barren-ground grizzly population acro...
متن کاملA Review of Grizzly Bear Harvest Management in British Columbia
This review builds on the information presented in Hamilton and Austin (2002). The purposes are: 1) to identify and present information on the outstanding scientific and management issues involved in assuring that hunting does not represent a conservation threat to grizzly bear populations and, 2) to outline potential future directions that are under consideration for grizzly bear harvest manag...
متن کاملConfronting Uncertainty in Wildlife Management: Performance of Grizzly Bear Management
Scientific management of wildlife requires confronting the complexities of natural and social systems. Uncertainty poses a central problem. Whereas the importance of considering uncertainty has been widely discussed, studies of the effects of unaddressed uncertainty on real management systems have been rare. We examined the effects of outcome uncertainty and components of biological uncertainty...
