Methane Production and Emission Mitigation in Oil Sands Tailings Concurrent with Hydrocarbon Degradation under Nitrogen Limited Conditions
DownloadFall 2020
Alberta’s oil sands generate large volumes of tailings from bitumen ore processing. These tailings ponds produce biogenic methane, which can be measured across 60-80% of the tailings surface. Based on current surface area data and emissions studies, tailings ponds could account for 8% of Canada’s...

Collins, Catherine Elizabeth Victoria
Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...

Performance and Methane Emissions of RFI Selected Cattle in Drylot and Under Open Range Conditions
DownloadSpring 2018
Residual feed intake (RFI) is a moderately heritable trait that can be used to measure feed efficiency in beef cattle, and thereby reduce feed related costs. RFI has been primarily evaluated under drylot conditions where diet, feed intake and activity levels are controlled and foraging behaviour...

Recovery of Legumes in Northern Temperate Pastures Following the Application of Broadleaf Herbicides
DownloadFall 2013
Field and greenhouse trials were conducted to assess the breakdown of soil residues of two broadleaf herbicide bioactives, aminopyralid and aminocyclopyrachlor, as well as associated legume reestablishment/recovery and pasture sward production dynamics. Greenhouse trials indicated legume seedling...
