Resprouting is an important adaptation to aboveground disturbance, whereby plants develop new shoots after loss or death of a portion of their aboveground biomass. Aspen (Populus tremuloides Michx.) is a foundational tree species in the boreal forests of North America and is a prolific...

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...

A field experiment from 2012 to 2013 at two locations in northeastern Alberta examined the short-term success of different fen revegetation strategies following the removal of infrastructure (road and well-pad) associated with oil extraction. Although all treatments resulted in limited overall...

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...

In the winter, snow can present a major challenge to large mammals by impeding locomotion, limiting food availability, and imposing additional energetic costs during travel. This thesis examines the effects of snow conditions on the fine-scale movement patterns of grey wolves (Canis lupus) in a...

Norris, Charlotte E.

The western boreal forest of Canada, where the upland regions are dominated by stands of aspen (Populus tremuloides Michx.) and spruce (Picea glauca (Moench) Voss), is now home to novel ecosystems, i.e.; ecosystems composed of reclaimed stands formed from trees planted on constructed...

Lankau, Hedwig Erika Gertraude

I investigated how songbirds respond to seismic lines as the vegetation cover on lines regenerates and how long seismic line effects on songbirds persist. I found that line age was poorly correlated with natural vegetation recovery and that after an initial increase in recovery after 20 years the...

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...

The recent open pit mining for oil sands in the Athabasca Oil Sands Region (AOSR), northern Alberta has created an unprecedented industrial scale disturbance whose ecological consequences is not well understood, and requires intensive investigation. This study focused on the temporal dynamics of...

Growing anthropogenic development in response to rising demands for natural resources is a major concern for freshwater fish, particularly in resource rich regions such as Canada’s boreal forest. Expanding networks of industrial resource roads has led to the installation of hundreds of thousands...
