Identifying historical climate-growth limitations of white spruce (Picea glauca) populations across North America
DownloadSpring 2021
Climate change may cause reduced forest productivity and higher tree mortality due to water deficits that result from increased evapotranspiration. Such limitations may occur in some areas of the North American boreal forest, where precipitation is low and warming trends are high. This thesis...

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...

Integrating the building blocks of agronomy and biocontrol into an IPM strategy for wheat stem sawfly
Download2011-01-01
Beres, Brian L., Cárcamo, Héctor A., Weaver, David K., Dosdall, Lloyd M., Evenden, Maya L., Hill, Bernard D., McKenzie, Ross H., Yang, Rong-Cai, Spaner, Dean M.
The wheat stem sawfly(Cephus cinctus Norton [Hymenoptera: Cephidae]) is a serious threat to wheat (Triticum aestivum L.) and other cereal grains in the northern Great Plains. Insecticides have proven ineffective for sawfly control and can be detrimental to beneficial insects. The management of...

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...

SSHRC IG awarded 2021: My study of the food supply in France addresses two issues fundamental to civilian survival: state management of food supplies and civilian adaptations to scarcity. My project will reconstruct French food policy from 1939 to 1950, analyze the locations and logic for...

Long Term Effects of Wildfire on Permafrost Stability and Carbon Cycling in Northern Peatlands
DownloadFall 2017
Changing fire dynamics and increasing global temperatures are causing changes to the fire regime and permafrost stability in the Arctic. Models have separately predicted the widespread thawing of permafrost and increasing magnitude and intensity of wildfires over the next century. However, while...

Mapping a Species-level Trophic and Non-trophic Multilayer Network of Known Interactions for Boreal Tetrapods of North America
DownloadFall 2021
Mapping trophic and non-trophic species interactions and mapping ecosystem-wide ecological networks have become important research avenues in network ecology, but until recently these two avenues have been separate endeavors. Now, a framework exists to combine multiple interaction types into...

Fall 2018
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...
