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 کاملResilience in a Protected Area: Prospects for Fathom Five National Marine Park, Lake Huron, Canada
Introduction Building or maintaining resilience within a protected area is increasingly cited as a means to achieve long-term conservation goals in the face of climate change and other human impacts (e.though there is an established body of ecological and social–ecological knowledge related to resilience concepts, in application it is still conceptually and methodologically early in its develop...
متن کاملBlack bear (Ursus americanus) survival and demography in the Bow Valley of Banff National Park, Alberta
We studied survival and demography of black bears, Ursus americanus, in Banff National Park (BNP) from 1994 to 2000 to test the efficacy of National Park protection. We monitored 25 radiocollared bears an average of 1.9 years each for a total of 51.8 bearyears. Eighty-two percent of all mortality {n= \\) was human-caused, composed of highway mortality (36%), management mor tality (27%) and man...
متن کاملGenetic connectivity for two bear species at wildlife crossing structures in Banff National Park.
Roads can fragment and isolate wildlife populations, which will eventually decrease genetic diversity within populations. Wildlife crossing structures may counteract these impacts, but most crossings are relatively new, and there is little evidence that they facilitate gene flow. We conducted a three-year research project in Banff National Park, Alberta, to evaluate the effectiveness of wildlif...
متن کاملDemographic connectivity for ursid populations at wildlife crossing structures in Banff National Park.
Wildlife crossing structures are one solution to mitigating the fragmentation of wildlife populations caused by roads, but their effectiveness in providing connectivity has only been superficially evaluated. Hundreds of grizzly (Ursus arctos) and black bear (Ursus americanus) passages through under and overpasses have been recorded in Banff National Park, Alberta, Canada. However, the ability o...
