Growth and yield implications of site preparation, competition control, and climate in the western boreal forest
DownloadSpring 2011
The main goal of this thesis was to improve our understanding of the long-term effects of establishment treatments and climate change on lodgepole pine and white spruce growth in the western boreal forests. My dissertation also investigated the combined effects of climate and competition on white...

Physiological, ecological and environmental factors that predispose trees, stands and landscapes to infestation by tree-killing Dendroctonus beetles
DownloadSpring 2013
In the last century the frequency and severity of outbreaks of tree-killing Dendroctonus beetles (Coleoptera: Curculionidae) have increased. Small-scale drivers within trees likely drive outbreak dynamics across landscapes. At a small scale, variation in carbohydrate availability within the stems...

Pine Wars: A New Host Interactions between the mountain pine beetle (Dendroctonus ponderosae Hopkins) and its pine hosts in Canada's boreal forest
DownloadFall 2023
Mountain pine beetle (MPB) has undergone a climate change facilitated range expansion and has attacked and killed trees at higher latitudes and elevations than has ever been recorded. During outbreaks, MPB attack large healthy pine trees that will fight back against the colonizing beetles using...

Transcriptomic analyses of Pinus contorta responses to Grosmannia clavigera under contrasting levels of nitrogen availability
DownloadSpring 2021
In western Canada alone, the current mountain pine beetle (MPB) outbreak has devastated nearly 19 million hectares of pine forest, negatively impacting communities, industries and ecosystems. Reforestation efforts can benefit from a deeper understanding of the impact of nitrogen (N)-based...
