Nitrogen (N) and Phosphorous (P) deposition at high elevations has increased by 40% over the last fifteen years, causing concern for the 3000+ alpine ponds in Banff National Park. A novel whole-ecosystem experiment was used to test for the effects of elevated N and P deposition on benthic...

After decades of recent fire exclusion in southern Alberta, Canada, forests are progressively aging and landscape mosaics are departing from their historical conditions. A large-scale fire history study spanning three natural subregions: Subalpine, Montane and Upper Foothills, was undertaken to...

This study investigates the interactions between carbon dioxide, climate, and glaciers of the Canadian Rockies under a relatively conservative IPCC emission scenario for the 21st century through the use of the PSU/NCAR MM5 mesoscale model (MM) nested within the Princeton GFDL global...

The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

Climate change will continue to affect the Arctic more intensely than other biomes. These changes can have dramatic effects on biotic interactions that influence the functioning of these systems, including plant-herbivore interactions. Invertebrate herbivores strongly depend on external...

With a warming climate, northern ecosystems will face significant ecological changes such as permafrost thaw, increased frequency of forest fires, and shifting ecosystem boundaries including the spread of canopy-forming shrubs into tundra communities. A growing number of observations show...

Alpine tundra is notorious for its fragility and slow recovery following disturbance. Tourism is increasing in alpine areas, creating the need to improve our understanding of the impacts of recreation in these ecosystems. This study examined the impacts of hiking and off-highway vehicle use on...

Reclamation of northern disturbances is of increasing importance as industrial activities and associated infrastructure expands to accommodate growing human reliance on world ecosystems. Bryophytes are recognized as ecologically essential to northern ecosystems and effectively promoting their...
