Habitat change and the scale of predation risk
(2004)In their efforts to maximise fitness while reducing the probability of dying, animals must trade off food for safety. The trade-off is likely to depend on habitat and habitat change. I imagine an environment with both safe ... -
Is patch use determined by fine-scale microhabitat differences or density dependent habitat selection?
(2006)If individuals base their patch and habitat choices on fine-scale differences in microhabitat, then their use o f patches, defined by capture sites, should correspond with measures o f microhabitat. But if individuals ... -
Life on the edge : the role of habitat selection on vole density near forest boundaries
(1997)Theories of density-dependent habitat selection predict pronounced gradients of population density near habitat edges. Population density in high-quality habitats should decline toward edges with lower-quality habitats, ... -
Spatial scaling in northern landscapes : habitat selection by small mammals
(1994)I examined a series of simple and repeated northern landscapes in the Hudson Bay Lowland of Ontario to document regional and local patterns of population abundance of red-backed voles {Clethrionomys gapperi). I tested ...
