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...

Limnology of a Large Northern Lake (Lhù’ààn Mânʼ [Kluane Lake], Yukon) in an Era of Reconciliation and Rapid Climate Change
DownloadSpring 2022
Almost 60% of Canada’s freshwater drains North, where air temperatures are increasing at twice the global rate. Despite the exposure of northern lakes to higher rates of change and their ecological, hydrological, and cultural importance, baseline knowledge and monitoring of their water properties...

Local and regional demography in a migratory forest songbird and effects of forest management intensity
DownloadSpring 2014
The numerical response of forest birds to habitat alteration has been well documented in North America, but the underlying demographic processes driving these changes remain largely unknown. Among species sensitive to such alterations, the Ovenbird (Seiurus aurocapilla) shows one of the largest...

Fall 2015
Given high levels of human disturbance and projected rates of climate change, many species will be unable to keep pace with their shifting climatic ranges and thus face increased risk of extinction. This research investigated the use of assisted migrations for two rare and range-restricted plant...

Modeling the impacts of recent climate change on ecosystem productivity across North America
DownloadFall 2015
There is evidence of warming and changes in precipitation over recent decades in most regions of North America (NA) that are affecting ecosystem productivity. The impacts of these changes on land-atmosphere carbon exchange over a wide range of biomes are spatially heterogeneous and uncertain. In...
