Salt Affected Soils And Their Relationships With Plant Communities On Reclamation Well Sites
DownloadFall 2020
Salt affected soils are common around the world from natural causes or anthropogenic activities. Over 1030 million hectares of land worldwide are affected by salt or at risk of being affected. In Alberta, saline and sodic soils may occur with oil and gas production, increasing the risk of...

The Importance and Influence of the Human Dimensions in Grizzly Bear (Ursus arctos) Conservation
DownloadFall 2018
Conservation practitioners increasingly recognize the importance and influence of the social context in conservation outcomes. From local stories to newsprint articles, the language we use, the stories we tell, and the interactions we have with wildlife species can influence human relationships...

Ecology and life history of Coccophagus gossypariae (Hymenoptera: Aphelinidae), a parasitoid of Eriococcus spurius (Hemiptera: Eriococcidae)
DownloadSpring 2018
The American elm (Ulmus americana) is a valuable component of urban forests in Alberta. In many Alberta municipalities, the health of these trees is being heavily impacted by the invasive scale insect Eriococcus spurius (Hemiptera: Eriococcidae). Biological control of scales using hymenopteran...

Growth and yield implications of site preparation, competition control, and climate in the western boreal forest
DownloadSpring 2011
The main goal of this thesis was to improve our understanding of the long-term effects of establishment treatments and climate change on lodgepole pine and white spruce growth in the western boreal forests. My dissertation also investigated the combined effects of climate and competition on white...

Soil Organic Carbon Content and Stability, and Greenhouse Gas Emissions in Three Agroforestry Systems in Central Alberta, Canada
DownloadFall 2016
Western Canada’s prairie region is extensively cultivated for agricultural production, which is a large source of greenhouse gas (GHG) emissions. Agroforestry systems are common land uses across Canada, which integrate trees into the agricultural landscape and could play a substantial role in...

Festuca hallii (Vasey) Piper (Plains rough fescue) and Festuca campestris RYDB (Foothills rough fescue) Response to Seed Mix Diversity and Mycorrhizae
DownloadFall 2012
Rough fescue (Festuca hallii (Vasey) Piper (plains rough fescue) and Festuca campestris Rydb (foothills rough fescue) are long lived perennials that have been difficult to establish on disturbed sites. This research assessed the impact of seed mix diversity and suppression of arbuscular...

Evaluating trade-offs: the effects of foraging, biting flies, and footing on wood bison (Bison bison athabascae) habitat use
DownloadSpring 2018
Understanding the distribution of forage is important in predicting the distribution, habitat use (behaviour), movements, and fitness-related traits of large, grazing ungulates. Although this bottom-up perspective provides a foundation for understanding habitat supply and thus nutrition, foraging...

Resource allocation, water relations and crown architecture examined at the tree and stand-level in northern conifers
DownloadFall 2013
Variation in quantity of light has driven plants to employ many strategies in order to persist in high and low light. It is also a primary driver of lower branch mortality and crown recession. Fine roots and leaves are complimentary tissues representing belowground and aboveground resource...

Nitrous Oxide Emission Reduction in an Annual Cropping System as a function of Nitrification Inhibitors and Liquid Manure Injection Timings
DownloadFall 2016
Nitrous oxide (N2O) contributes to global warming and ozone depletion. Two-thirds of the global N2O emissions are derived from agricultural soils receiving manure or fertilizer applications. The goal of this study was to identify and develop management practices that can decrease N2O emissions...
