Influence of forest canopies on the deposition of methylmercury to boreal ecosystem watersheds
DownloadFall 2010
Methylmercury (MeHg) is a potent vertebrate neurotoxin and a contaminant of global concern. Increased anthropogenic emissions of mercury (Hg) to the atmosphere have led to increased bioaccumulation of MeHg in top predatory organisms such as fish, the consumption of which is the main exposure...

Interactions between the forest tent caterpillar (Malacosoma disstria Hubner) and its natural enemies: the effects of forest composition and implications for outbreak spread
DownloadFall 2011
Forest tent caterpillar (Malacosoma disstria Hübner; FTC), a major defoliator of aspen trees, occupies both aspen and mixedwood forest stands in Alberta’s boreal forest. Forest stand composition could influence the spatial pattern of FTC outbreaks if mortality from natural enemies differs...

Terrestrial vegetation contributes strongly to dynamic biosphere-atmosphere exchanges of mass and energy, through activities such as photosynthesis, that help shape the Earth’s climate. The boreal forest is located in high latitudes and subject to large seasonal temperature fluctuations and a...

Fall 2016
Roads are a prevalent, ever-increasing form of human disturbance on the landscape. In many places in western North America, energy development has brought human and road disturbance into seasonal winter range areas for migratory elk. In this population, I studied individual habitat selection...

Nutrient limitation of periphyton in agricultural streams: Implications for watershed management
DownloadSpring 2021
Freshwater streams are ecologically important as sources of habitat, unique biodiversity, and valued ecosystem services. Yet, stream health can be threatened by intensified nutrient loading derived from adjacent anthropogenic land-uses such as agricultural and municipal developments. Since algal...

Occupancy, Abundance, and Summer Ecology of the Western Tiger Salamander (Ambystoma mavortium Baird) in the Beaver Hills, Alberta
DownloadSpring 2016
The western tiger salamander (Ambystoma mavortium Baird) is a ‘species of special concern’ in the Canadian prairie provinces. Potential declines caused by habitat loss and fragmentation, emergent diseases, and fish stocking are reasons cited for this species conservation status. However, little...

Projecting boreal bird responses to climate change considering uncertainty, refugia, vegetation lags, and post-glaciation history
DownloadSpring 2016
Often referred to as North America’s bird nursery, the boreal forest biome provides a productive environment for breeding birds, supporting high species diversity and bird numbers. These birds are likely to shift their distributions northward in response to rapid climate change over the next...

Regional and local controls of surface water chemistry in the Boreal Plain and Shield transition of Canada
DownloadFall 2010
The Western Boreal Forest exhibits complex hydrogeology juxtaposed with rapid resource development. Predicting surface water chemistry to assess the influence of landuse and climate change is needed. The research purpose was to test if a global model (Gibbs), used to assess water chemistry...

Soil Mesostigmata (Arachnida: Parasitiformes) in boreal forests of Alberta: diversity and utility as indicators of disturbance
DownloadSpring 2018
Soils provide numerous ecosystem services, including provision of nutrients for plants, sequestration of greenhouse gases, and serving as habitat for soil animals. Soil animal diversity is immense, and many undescribed taxa still remain. One prominent group that inhabits soils is mites...

Fall 2011
Understanding how populations are structured and how they use natural and anthropogenic spaces is essential for effective wildlife management. A total of 510 barren-ground (Rangifer tarandus groenlandicus), 176 boreal (R. t. caribou), 11 mountain woodland (R. t. caribou), and 39 island (R. t....
