A comparison of coarse woody debris in post-harvest and post-fire island remnants a decade after disturbance in northern Alberta
DownloadFall 2022
Retention forestry is the practice of retaining forest structure within cut-blocks at harvest sites and is practiced widely throughout the world. Although retention practices are modelled on the propensity for fires to leave behind a variety of biological legacies or structural elements, the...

An Alternate Indicator System for Nutrient Supply as Part of Ecosystem Function, a Component of Reclamation Success in the Athabasca Oil Sands Region
DownloadFall 2017
Northeastern Alberta faces the challenges of reclaiming a vast area that has been disturbed my oil sands mining, cumulatively 896 km2 and increasing as of December 2013. The limited resources available for reclamation and expensive costs of undertaking the process necessitates that reclamation be...

This thesis explores the influence of non-structural carbohydrates (NSC), seedling size, and root:shoot ratio (RSR) on jack pine (Pinus banksiana Lamb.) seedling performance under different drought intensities in a growth chamber and after outplanting on a reclamation site. NSC content, size, and...

Induced monoterpene responses in jack pine: defence against jack pine budworm and a fungal associate of the mountain pine beetle
DownloadFall 2010
My thesis research investigated monoterpene responses in jack pine (Pinus banksiana Lamb.) to different agents to better understand how these responses may influence the spread of the mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) in the boreal forest. The results support that...

Interactions Between Host Trees, Bacteria, and Fungi: Impacts on Mountain Pine Beetle (Dendroctonus ponderosae) Reproduction
DownloadFall 2012
Warming winter trends due to climate change have allowed for a range expansion of the mountain pine beetle, and the beetle now threatens Canada’s economically and ecologically important jack pine forests. The beetle’s success in jack pine trees will depend upon successful colonization of the...

Fall 2012
Intra and inter-plant signalling was investigated in jack pine (Pinus banksiana) seedlings in response to jack pine budworm (Choristoneura pinus, Lepidoptera: Tortricidae) feeding. Defoliation was followed by a fungal inoculation by blue stain fungus (Grosmannia clavigera) to assess resistance....

Playing with fire: Dendroctonus ponderosae (mountain pine beetles) in post-burn lodgepole pine forests
DownloadSpring 2015
Dendroctonus ponderosae, an aggressive tree-killing bark beetle, is one of the most significant insects in the coniferous forests of western North America. Although D. ponderosae is restricted to weakened host trees at low-density populations, fire can suddenly increase the number of suitable,...

The role of microtopography in vegetation colonization and early forest development on mine reclamation sites
DownloadSpring 2023
Microsite heterogeneity is an important variable that drives biodiversity in forests. Current forest reclamation practices often do not incorporate site heterogeneity in their practices which might pose a challenge to the reclamation goals of restoring disturbed sites to resilient and sustainable...

Variations in jack pine (Pinus banksiana) monoterpene composition and subsequent effects on pheromone production by mountain pine beetle (Dendroctonus ponderosae)
DownloadSpring 2015
The secondary compounds of pines (Pinus) can strongly affect the physiology, ecology and behaviour of bark beetles (Coleoptera: Curculionidae, Scolytinae) that feed on host sub-cortical tissues. Jack pine (Pinus banksiana) has a wide distribution range in North America and thus variations in its...
