Impacts of aggregated retention harvesting on the diversity patterns of nocturnal moth species assemblages in the mixedwood boreal forest of northwestern Alberta
DownloadFall 2012
The loss of mature forest habitat from forest harvesting represents a substantial threat to the diversity of nocturnal boreal forest moth assemblages. In this study, I used spatial patterns of species diversity to quantify the effects of aggregated green tree retention harvesting on the diversity...

Lejoly, Justine Daniele Marthe
Exotic species of earthworms are invading North American forests, where native earthworms were extirpated by the last glaciation. The invasion of these ecosystem engineers can alter soil organic matter (SOM) dynamics, carbon (C) persistence, and ecosystem functioning. While the topic has been...

Influence of forestry and conspecific attraction on habitat use and reproductive activity of the Canada warbler (Cardellina canadensis) in the western boreal forest: Implications for critical habitat identification
DownloadSpring 2017
Recovery strategies for species at risk are legally mandated in Canada and the Government of Canada must identify which habitat is important for a species and which activities result in its destruction. The Canada Warbler (Cardellina canadensis) has been designated as a threatened species in...

Natural Recovery of Upland Boreal Forest Vegetation on a Hummocky Peat-Mineral Mix Substrate in the Athabasca Oil Sands Region, Alberta
DownloadSpring 2010
This research investigated the natural recovery of upland boreal forest vegetation on a peat-mineral mix substrate in the Athabasca Oil Sands Region, Alberta. Three sites, aged 26 to 34 years, were assessed to determine effects of substrate (pH, electrical conductivity, texture), topography,...

A major barrier to reclamation after oil sands mining is lack of commercially available, diverse native plant seeds and propagules for revegetation. Potential of LFH (forest floor material) developed on coarse textured soil for establishing native plants and how salvage, placement and storage...

Leafrollers moths are one of the most ecologically and economically important groups of herbivorous insects. These Lepidoptera are an ideal model for exploring the drivers that modulate the processes of diversification over time. This thesis analyzes the evolution of Choristoneura Lederer, a well...

Postbreeding movement patterns and multiscale habitat use of adult wood frogs (Lithobates sylvaticus) at urban wetlands of Edmonton, Alberta.
DownloadSpring 2014
Many studies have focused on the effects of urbanization on amphibian species richness, abundance and diversity, but few studies have quantified the effect on amphibian movement behaviour or habitat use. At 11 urban wetlands in Edmonton, Alberta, I examined the postbreeding movement behaviour and...

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...

Snowfall, travel speed, and seismic lines: The effects of snow conditions on wolf movement paths in boreal Alberta
DownloadSpring 2016
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...
