Fall 2012
In this study, growth of seven hybrid poplar clones and one pure poplar clone was investigated in relation to leaf, shoot, and root physiology under field conditions. Clones included: Walker (24 - P. deltoides x P. xpetrowskyana), Assiniboine (25 - open pollinated Walker cv. Assiniboine),...

Trembling aspen (Populus tremuloides Michx.) is a dioecious clonal tree species with broad distribution in North America. In dioecious species, sexes are predicted to perform differently, based on the principle of allocation and the energy costs associated with reproduction. Aspen reproduce...

Genetic variation of hydraulic and wood anatomical traits in hybrid poplar and trembling aspen
Download2011
Hacke, U.G., Schreiber, S.G., Hamann, A., Thomas, B.R.
•Intensive forestry systems and breeding programs often include either native aspen or hybrid poplar clones, and performance and trait evaluations are mostly made within these two groups. Here, we assessed how traits with potential adaptive value varied within and across these two plant groups....

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 clavigera

Kayal, Walid El, Cooke, Barry J., Linsky, Jean, Arango-Velez, Adriana, Galindo González, Leonardo M., Cooke, Janice E.K., Meents, Miranda J., Lusebrink, Inka
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...

Regional-scale hydrologic settings buffer black spruce regeneration in the presence of post-fire droughts
DownloadSpring 2024
Lanti-Traikovski, Alexander A.
Climate change is increasing the frequency of droughts and wildfires, reducing tree recruitment, and altering post-fire species composition. In Canada’s western boreal forests, postfire recruitment, particularly of drought-intolerant coniferous species like black spruce, has declined in recent...

Reimaging Resource Constraints and Affordances: Smallholder, Environment and State Dynamics in Wello, Ethiopia
DownloadFall 2012
In this dissertation, I explore and analyze smallholders’ perceptual and cultural understandings of environmental opportunities and constraints regarding land, soil, rain and trees in mixed-crop-livestock agriculture among rural communities of Wärräbabbo in Wello, northeast Ethiopia. Also, I...

Selected Aspects of Plant Responses to Elevated pH, Salinity and Drought: Implications for Oil Sands Revegetation
DownloadSpring 2021
Elevated salinity, high pH, and drought are among the most challenging environmental factors affecting the growth and survival of plants in oil sands reclamation areas. In my thesis research, I focused on the selected aspects of these environmental stresses to better understand their potential...

The Effect of Water Limitation on Volatile Emission, Tree Defense Response, and Brood Success of Dendroctonus ponderosae in Two Pine Hosts, Lodgepole, and Jack Pine
Download2016
Lusebrink, Inka, Erbilgin, Nadir, Evenden, Maya L.
The mountain pine beetle (MPB; Dendroctonus ponderosae) has recently expanded its range from lodgepole pine forest into the lodgepole × jack pine hybrid zone in central Alberta, within which it has attacked pure jack pine. This study tested the effects of water limitation on tree defense response...

The lodgepole x jack pine hybrid zone in Alberta, Canada: A stepping stone for the mountain pine beetle on its journey east across the Boreal forest?
Download2013-01-01
Evenden, Maya L., Erbilgin, Nadir, Lusebrink, Inka
Historical data show that outbreaks of the tree killing mountain pine beetle are often preceded by periods of drought. Global climate change impacts drought frequency and severity and is implicated in the range expansion of the mountain pine beetle into formerly unsuitable habitats. Its expanded...
