Winter hunting patterns of wolves in and near glacier national park, Montana

摘要: Wolves (Cams lupus) will become an important mortality factor on ungulate populations as they recolonize the western United States. Innovative means of altering wolf-ungulate dynamic to enhance either prey security or predator population may be necessary meet management objectives. From 1990 1996, we examined multiscale factors affecting hunting success wolves during winter in a multi-prey system northwestern Montana and southeastern British Columbia, Canada. Within their home ranges, concentrated wintering areas white-tailed deer (Odocoileus virginianus). They used with features that facilitated travel (low snow vegetative cover) habitats were favored by deer. Along routes, killed higher densities lower elk (Cervus elaphus) moose (Alces alces) than expected, based occurrence these prey. greater hiding-stalking cover, less slope, closer water along wolf routes. More main valley bottom ravines other landscape classes located more at flatter sites
