A species-diagnostic SNP panel for discriminating lodgepole pine, jack pine, and their interspecific hybridsDownload
Accurate stock identification is important for forest management, yet this can be a challenge for tree species that hybridize naturally. Species discriminating molecular markers provide a means to identify stock with high accuracy. In Canada, lodgepole pine (Pinus contorta Dougl. ex Loud. var....
An Alternate Indicator System for Nutrient Supply as Part of Ecosystem Function, a Component of Reclamation Success in the Athabasca Oil Sands RegionDownload
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...
Characterizing the physical and genetic structure of the lodgepole pine × jack pine hybrid zone: mosaic structure and differential introgressionDownload
Understanding the physical and genetic structure of hybrid zones can illuminate factors affecting their formation and stability. In north-central Alberta, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb) form a complex and poorly defined hybrid...
Chemical similarity between historical and novel host plants promotes range and host expansion of the mountain pine beetle in a naïve host ecosystemDownload
Host plant secondary chemistry can have cascading impacts on host and range expansion of herbivorous insect populations. We investigated the role of host secondary compounds on pheromone production by themountain pine beetle (Dendroctonus ponderosae) (MPB) and beetle attraction in response to a...
Diurnal and annual exchanges of mass and energy between an aspen-hazelnut forest and the atmosphere: testing the mathematical model ecosys with data from the BOREAS experimentDownload
There is much uncertainty about the net carbon (C) exchange of boreal forest ecosystems, although this exchange may be an important part of global C dynamics. To resolve this uncertainty, net C exchange has been measured at several sites in the boreal forest of Canada as part of the Boreal...
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 beetleDownload
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...
Influence of water deficit on the molecular responses of Pinus contorta × Pinus banksiana mature trees to infection by the mountain pine beetle fungal associate, Grosmannia clavigeraDownload
Conifers exhibit a number of constitutive and induced mechanisms to defend against attack by pests and pathogens such as mountain pine beetle (Dendroctonus ponderosae Hopkins) and their fungal associates. Ecological studies have demonstrated that stressed trees are more susceptible to attack by...
Interactions Between Host Trees, Bacteria, and Fungi: Impacts on Mountain Pine Beetle (Dendroctonus ponderosae) ReproductionDownload
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...
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....
