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...

Spring 2016
Understanding factors affecting elemental carbon stocks on Alberta’s grasslands is of special importance with recent policy shifts focusing on climate change and carbon (C) emissions. A large part of Alberta is native prairie utilized by the beef industry. This study examined soil and vegetation...

Investigation of Causal Mutations in Livestock and Companion Animals Using Whole-Genome Sequencing (WGS) and Bioinformatics
DownloadSpring 2024
In this thesis project, three studies were conducted, aimed at identifying the causal variants responsible for phenotypic/genotypic sex discordance in cattle, copper toxicosis in Dalmatian dogs, and low fertility/infertility in cattle. In all three studies, whole-genome sequencing (WGS) and...

Venison to beef and deviance from truth: biotelemetry for detecting seasonal wolf prey selection in Alberta
DownloadFall 2010
An abrupt interface between mountains and prairies in southwestern Alberta means wilderness areas and carnivore populations overlap cattle grazing lands. Consequently, there is concern about the effects of large carnivores, especially wolves, on livestock. I used GPS clusters and scat samples...
