SPATIOTEMPORAL FACTORS INFLUENCING THE DISTRIBUTION AND ABUNDANCE OF GRIZZLY BEARS (URSUS ARCTOS) INHABITING THE BARREN-GROUNDS OF THE CENTRAL CANADIAN ARCTIC
Spatially-explicit capture-recapture (SCR) methods can be used for estimating animal density and testing biogeographic hypotheses about the influence of landscape heterogeneity on animal space use. I used SCR to estimate the density of grizzly bears inhabiting the tundra of the central Canadian Arct...
