Afforestation and stand age affected soil respiration and net ecosystem productivity in hybrid poplar plantations in central Alberta, Canada
DownloadFall 2010
Afforestation and stand development can significantly affect soil respiration and net ecosystem productivity (NEP). I studied 1) the effects of afforestation on NEP by comparing cropland previously planted to barley (on a barley-barley-alfalfa-alfalfa-alfalfa rotation) and that converted to a...

Climate change is currently a central problem in ecology, with far-reaching effects on species that may be diffcult to quantify. Ectothermic species which rely on environmental cues to complete successive stages of their life history are especially sensitive to temperature changes and so are good...

High-resolution regional climate simulations of the Karakoram, Himalaya have been performed for investigation into the atmospheric dynamics in this region, and their role in the Karakoram’s snowfall accumulation and glacial evolution. It has been seen through a combination of field measurements...

Bioclimate envelope models are widely used to project potential species habitat under changing climate. Conceptually, these models are also well suited to match natural resource management practices to new climatic realities, for example by guiding species choice in reforestation programs....

This thesis is about climate change attitudes in Alberta, Canada. It applies a bivariate logistic analysis to the data gathered from a random stratified sampling survey held in Alberta in 2008. It finds that belief in the anthropogenic climate change and Conservative political ideology factors...

The impact of recreational activities on an alpine vascular plant community in the Canadian Rockies
DownloadFall 2010
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...

The interactive effects of climate, social structure, and life history on the population dynamics of hoary marmots (Marmota caligata)
DownloadFall 2010
I used 8 years of mark-recapture data to test alternative hypotheses about the relative influence of winter climate, social structure, and life history on survival, reproduction, and population dynamics of hoary marmots (Marmota caligata) in the southwest Yukon. Climate, characterized by the...

Abstract This thesis explores the risk perception of climate change among Egyptians who reside in Canada and Egyptians who reside in Egypt. It applies a quantitative comparative analysis of these two populations to assess differences in risk perception of climate change and the influence of world...

Factors driving range expansion of white-tailed deer, Odocoileus virginianus, in the boreal forest of northern Alberta, Canada
DownloadFall 2011
A large suite of species, across numerous taxa, are expanding their geographic ranges, with potential impacts on species, communities and ecosystems. This has increased interest in understanding the mechanisms driving range change and anticipating future changes in species’ distributions....

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...
