Consequences of a Refuge for the Predator-Prey Dynamics of a Wolf-Elk System in Banff National Park, Alberta, Canada
Refugia can affect predator-prey dynamics via movements between refuge and non-refuge areas. We examine the influence of a refuge on population dynamics in a large mammal predator-prey system. Wolves (Canis lupus) have recolonized much of their former range in North America, and as a result, ungulate prey have exploited refugia to reduce predation risk with unknown impacts on wolf-prey dynamics...

متن کاملPredator-Prey Management in the National Park Context: Lessons from a Transboundary Wolf, Elk, Moose and Caribou System
Wolves {Canis lupus) are recolonizing much of their former range within the lower 48 states through active recovery (Bangs and Fritts 1996) and natural dispersal (Boyd and Pletscher 1999). Wolf recovery is being touted as one of the great conservation successes of the 20̂ ̂century (Mech 1995; Smith et al. 2003). In addition to being an important single-species conservation success, wolf recovery ...
متن کاملEcology and Society: The energetic cost of path sinuosity related to road density in the wolf community of Jasper National Park
In their recent article, Whittington et al. (2004) show that wolf packs increase their path sinuosity in the vicinity of roads and highly used trails. This path variable is defined as the relationship between the length of the path traveled (L) and the net displacement of the animal (R). The authors present a model that explains path sinuosity using the distance to prey and the density of roads...
متن کاملContext dependence of elk (Cervus elaphus) vigilance and wolf (Canis lupus) predation risk
To assess the relationship between predation risk perceived by elk (Cervus elaphus L., 1758) as evidenced by vigilance, we conducted focal animal observations in elk winter range.We stratified our observations in Glacier National Park, Montana, USA, andWaterton Lakes National Park, Alberta, Canada, in valleys with three wolf (Canis lupus L., 1758) population levels (Saint Mary Valley: no wolf; ...
