Getting to the root of the matter: grizzly bears and alpine sweetvetch in west-central Alberta, Canada
DownloadSpring 2012
Wildlife habitat selection is influenced by gender, offspring-dependency, resource availability, and spatiotemporal variation in resource nutrition. In consideration of these factors, this thesis examines alpine sweetvetch (Hedysarum alpinum) root and its relationship to grizzly bears (Ursus...

Grassland vegetation diversity responses to the reintroduction of Wood Bison (Bison bison athabascae) in Aishihik, Yukon
DownloadSpring 2020
In the southwest Yukon, the rain shadow effect of the Coast Mountains produces xeric south-facing slopes that support some of the most northerly grasslands in North America. These dry and nutrient poor forb-dominated grassland pockets within the vast matrix of boreal forest support distinctive...

Greenhouse Gas Emissions Following Tillage Reversal on a Black Chernozem and a Gray Luvisol in Alberta
DownloadFall 2012
Agricultural soils under long-term no till management have been well known to sequester atmospheric carbon in soil organic matter and to reduce emissions of greenhouse gases. Our study aimed at quantifying CO2 and N2O emissions from Black Chernozems and Gray Luvisols managed under long-term (~ 30...

Greenhouse Gas Emissions from Northern Wetlands and Lakes: Circumpolar and Local Perspectives
DownloadFall 2021
Methane (CH4) emissions from Boreal-Arctic wetlands and lakes are likely to increase in a warming climate, and thus add to the atmospheric burden of greenhouse gases (GHG). However, there are large uncertainties in current estimates of CH4 emissions from northern ecosystems, and I have a limited...
