Application of manure from cattle fed with different diets affects soil properties and greenhouse gas emissions
DownloadSpring 2019
Cattle production contributes the largest portion of livestock agricultural greenhouse gas (GHG) emissions in Canada mostly in the form of methane (CH4). Efforts to reduce CH4 emissions have led to modification of diet composition for livestock, resulting in a corresponding change in manure...

Biodiversity of soil arthropods in a native grassland in Alberta, Canada: obscure associations and effects of simulated climate change
DownloadFall 2013
Soils have traditionally been treated as a “black box” due to the challenges of studying this complex medium. The living component of soil consists of a complex network of roots and mostly very small, highly abundant, and extremely diverse group of microbes, protists, and other invertebrates. In...

Characterization of novel envelope proteins and their relationship with the Cpx response and stress resistance in Escherichia coli
DownloadFall 2022
Stress is a major factor every organism needs to mitigate to survive. Environmental factors such as oxygen content, temperature, and alkalinity can all induce stress and prevent life from progressing. For Escherichia coli and other members of the mammalian gastrointestinal tract they need to...

Provided that infectious prions (PrPTSE) are inactivated, composting of specified risk material (SRM) may be a viable alternative to rendering and land filling. The overall objective of this research was to utilize laboratory-scale composters to assess the degradation of SRM and PrPTSE during...

Conservation and ecology of bryophytes in partially harvested boreal mixed-wood forests of west-central Canada
DownloadFall 2010
This thesis examined the efficacy of residual forest structure for the preservation and recovery of bryophytes five to six years after partial canopy harvest in boreal mixed-wood forests of northwestern Alberta, Canada. Bryophytes were sampled in two forest types that differed in pre-harvest...

Effects of Biochar, Fertilizer and Shelter Treatments on the Vegetation Development following Coal Mine Reclamation
DownloadFall 2016
Poor quality cover soil, a lack of propagules, and availability of suitable microsites can be serious challenges in the re-vegetation success of surface mines. In my thesis research, I examined the response of total cover, species richness and community composition of colonizing vegetation on a...

Effects of long-term nitrogen and sulfur deposition on soil microbial communities and soil properties in the Athabasca oil sands region in northern Alberta, Canada
DownloadFall 2016
Intensified oil sands activities have resulted in elevated levels of nitrogen (N) and sulfur (S) deposition in the mixedwood boreal forest in the Athabasca oil sands region (AOSR) of northern Alberta, Canada. The deposition of N and S can affect the surrounding ecosystem and it is important to...
