Spring 2024
Trembling aspen (Populus tremuloides Michx.) is a dioecious clonal tree species with broad distribution in North America. In dioecious species, sexes are predicted to perform differently, based on the principle of allocation and the energy costs associated with reproduction. Aspen reproduce...

Climate change could significantly alter precipitation and water availability in different parts of the world. Moreover, during the course of the 21st century, climate change impact can potentially enhance the severity and frequency of extreme precipitation and also increase prolonged drought...

Guiding Douglas-fir seed selection in Europe under changing climates: bioclimatic envelope model predictions versus growth observed in provenance trials
DownloadFall 2013
Douglas-fir (Pseudotsuga menziesii (Mirbel) Franco) is one of the most ecologically and economically important tree species in both its native range in North America and in its introduced range in Europe. The aim of this research is to inform the European Douglas-fir reforestation strategy under...

Spring 2014
This thesis investigates three areas under the theme of household structure, climate change and livelihoods in southern Africa. The use of female-headship to identify vulnerable subgroups and to direct poverty-alleviation policies is a contentious issue in the literature. In the first paper of...

Fall 2019
Within the Boreal Plains of north-central Alberta, catchments situated within low permeability glacial terrain are composed of a mosaic of landscape units including ponds, peatlands, and upland aspen forest ecosystems within a sub-humid climatic zone where water deficit conditions are frequent. ...

Identifying historical climate-growth limitations of white spruce (Picea glauca) populations across North America
DownloadSpring 2021
Climate change may cause reduced forest productivity and higher tree mortality due to water deficits that result from increased evapotranspiration. Such limitations may occur in some areas of the North American boreal forest, where precipitation is low and warming trends are high. This thesis...

Identifying seasonal Lake Sturgeon (Acipenser fulvescens) movement patterns and habitat selection in the South Saskatchewan River Basin
DownloadFall 2016
Lake Sturgeon (Acipenser fulvescens Rafinesque 1817) have experienced population declines throughout their range. In Alberta, low density age-class distributions, irregular recruitment, critically low spawning potential ratios and other factors led to a 2007 designation of “Threatened” for this...

Influence of Precipitation, Temperature, and Climate Change on Landslide Hazards in Western Canada
DownloadSpring 2024
Canada experiences a significant number of landslides each year, posing substantial risks to safety, infrastructure, economic activities, and the environment. Over the last two and a half centuries, Canada has witnessed approximately 800 fatalities attributed to landslides, which has made...

Influence of wildfire and permafrost thaw on dissolved organic carbon (DOC) in northern peatlands; implications for lability and downstream transport
DownloadFall 2017
Peatlands in Canada’s western boreal forest are a major source of dissolved organic carbon (DOC) to downstream ecosystems, where DOC regulates carbon cycling, and can affect ecosystem productivity and habitat quality. Subarctic ecosystems are becoming increasingly vulnerable to the effects of...

Investigating Fire as a Silvicultural Tool for Regeneration of Mountain Pine Beetle-killed Serotinous Pine of Northern Alberta
DownloadSpring 2016
Serotinous pine forests in Western Canada are threatened by a record-breaking mountain pine beetle (Dendroctonus ponderosae; MPB) outbreak - the largest recorded in Western North America. Forest managers are concerned with whether these closed-cone MPB-killed forests will successfully regenerate....
