Influence of high-order mechanics on simulation of glacier response to climate change: insights from Haig Glacier, Canadian Rocky Mountains
Evolution of glaciers in response to climate change has mostly been simulated using simplified dynamical models. Because these models do not account for the influence of high-order physics, corresponding results may exhibit some biases. For Haig Glacier in the Canadian Rocky Mountains, we test this hypothesis by comparing simulation results obtained from 3-D numerical models that deal with diff...
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...
متن کاملGrizzly Bear Density in Glacier National Park, Montana
We present the first rigorous estimate of grizzly bear (Ursus arctos) population density and distribution in and around Glacier National Park (GNP), Montana, USA. We used genetic analysis to identify individual bears from hair samples collected via 2 concurrent sampling methods: 1) systematically distributed, baited, barbed-wire hair traps and 2) unbaited bear rub trees found along trails. We u...
متن کاملYMCA hiking patterns at Rocky Mountain National Park: implications for public health.
BACKGROUND There is little data on hiking patterns in national parks to support hiking behavior as a vehicle to meet the joint YMCA, CDC, and National Park Service initiatives to encourage physical activity through public land use. METHODS The YMCA of the Rockies hiking program provided data from Hike Report forms completed after 343 supervised hikes for one summer season in Rocky Mountain Na...
