Benthic Responses to Nitrogen and Phosphorus Deposition on Alpine Ponds in Banff National Park: A Replicated Whole-Ecosystem Experiment
DownloadFall 2012
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...

Shrub encroachment in arctic and alpine tundra: Patterns of expansion and ecosystem impacts.
DownloadFall 2011
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...
