Fall 2020
Oil sands mining is a significant disturbance in the Canadian boreal forest. One objective for reclamation after mining is to create a self-sustaining ecosystem, which includes establishing a native plant community. For this thesis, study one evaluates the different plant assembly mechanisms,...

Fall 2013
Drilling fluid, also referred to as drilling mud, is used to lubricate and cool the drilling apparatus, transport drill cuttings to the surface and seal off porous geologic formations. Disposal of drilling fluid is a growing concern to the global oil and gas industry as it can require extensive...

Fall 2018
For male breeding songbirds, song rate varies throughout the breeding season and tends to be correlated with breeding-cycle stages. Although these patterns have been well documented, to our knowledge, this relationship has not been used to predict a bird’s breeding status through acoustic...

Predictive Mapping of Yellow Rail (Coturnicops noveboracensis) Density and Abundance in the Western Boreal Forest via Ground and Satellite Remote Sensors
DownloadFall 2019
The Yellow Rail (Coturnicops noveboracensis) is a small, secretive, wetland bird, which is apparently rare throughout most of its range. Almost nothing is known about its abundance and density in the wetlands of the western boreal forest. Emerging technologies have enabled us to effectively...

Productivity and carbon accumulation potential of transferred biofilms in reclaimed oil sands-affected wetlands
DownloadSpring 2011
Biofilms are significant contributors to primary production, nutrient cycling, bio-stabilization and the food web of wetland ecosystems. Photoautotrophic biomass (PB) and primary production (PP) were determined for biofilms exposed to various treatments and materials in wetlands near Fort...

Rebuilding the boreal: analyzing the replicability of the bacterial community structure and soil functioning of forest floor mineral mix with peat subsoil admixtures
DownloadSpring 2017
Alberta law requires reclamation of lands disturbed by surface mining operations, such as those occurring at the Athabasca Oil Sands Region, however, reclamation rates lag far behind continued disturbance rates. Due to cost, mining companies must make use of the materials on site, of which the...

Fall 2020
The dissertation is concerned with how Inuit artists are reclaiming knowledge from early ethnographic texts. Early ethnographic texts, such as the writing, photographs, and cultural products produced or acquired by Danish-Greenlandic explorer Knud Rasmussen during the Fifth Thule Expedition...

Spring 2012
Reclamation of thousands of limestone quarries around the world is challenged by an extremely limiting environment, including steep slopes, high calcium carbonate substrates with low nutrients and low water holding capacity. These issues were addressed at the Exshaw quarry in the Rocky Mountains...

Reclamation of wetland habitat in the Alberta oil sands: generating assessment targets using boreal marsh vegetation communities
DownloadFall 2010
Thousands of hectares of wetlands are being destroyed by oil sands mining in Alberta, and the industry must undertake wetland reclamation to compensate for these losses. Wetland vegetation has developed at some previously mined sites, however reclamation is thus far exploratory, and limited in...

Reproduction and abundance of the wood frog (Lithobates sylvaticus) in post-harvest variable retention forests
DownloadFall 2017
Many aquatic-breeding amphibians require freshwater habitat for reproduction and terrestrial habitat for refuge, foraging, and overwintering. Variable retention harvesting is a technique where live trees and other forest features are retained during timber harvesting in patterns that emulate...
