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...

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...

Role of host identity, stand composition, soil type and disturbance severity in structuring ectomycorrhizal communities in the boreal forest
DownloadSpring 2018
The symbiosis between trees and ectomycorrhizal fungi (EMF) is essential for tree establishment and survival in the boreal forest because it is a disturbance prone ecosystem characterized by long harsh winters and low nutrient mobility. Ectomycorrhizal fungal community composition can be...

Fall 2011
Festuca hallii (plains rough fescue), a late-seral bunchgrass and long-lived perennial, is difficult to restore once disturbed. Once dominant in grasslands throughout central Alberta, F. hallii now occurs in remnants, a result of agricultural and residential development, and oil and gas...

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...

Saproxylic Beetles (Coleoptera) Associated With Aspen Deadwood in Broad-Leaved Boreal Mixedwood Stands
DownloadFall 2012
I assessed deadwood-associated (i.e., ‘saproxylic’) beetles (Coleoptera) along a decay gradient of trembling aspen in mature deciduous stands of the boreal mixedwood forest in NW Alberta. Various collection methods were employed to sample saproxylic beetle species. Assemblages differed between...

Microbial communities are responsible for biogeochemical processes in soils such as nutrient cycling and organic matter formation, which are essential to the establishment of vegetation and ecosystem sustainability. Phospholipid fatty acid analysis, microbial respiration and enzymatic activities...

Spatial and Temporal Variations in Tree Growth, Mortality, and Biodiversity in Alberta Forests
DownloadSpring 2014
Understanding the spatial and temporal variation of tree demographic rates and biodiversity is essential for predicting the dynamics of forest ecosystems and their responses to changing environments. This thesis contributes to that understanding through modeling the long-term change in tree...
