Adaptation of trembling aspen and hybrid poplars to frost and drought: implications for selection and movement of planting stock in western Canada
DownloadFall 2012
This study contains a series of experiments to evaluate growth performance and survival of hybrid poplars (Populus spp.) and trembling aspen (Populus tremuloides Michx.) in boreal planting environments in western Canada. Ecophysiological traits related to drought resistance and winter survival...

Adaptation of white spruce populations to extreme climate events: implications for assisted migration practices in Western Canada
DownloadSpring 2019
The movement of seed sources from south to north has been proposed as a tool to mitigate the effect of climate change on forest productivity and mortality. Southern provenances, coming from warmer regions are expected to better utilize the extended growing seasons expected under climate warming....

Adaptation of white spruce to climatic risk environments in spring: implications for management under climate change
DownloadFall 2022
The timing of spring dormancy release and bud break in trees is an adaptive trait with potentially important management implications. Depending on how spring phenology is controlled, climate warming may disrupt the synchronization of bud break with the available growing season. Further,...

Drought and defoliation-induced alterations to the structure and function of the vascular tissue in trees
DownloadSpring 2019
Observations of tree dieback and mortality from climate change-induced drought has been documented across the world, however the mechanisms of tree mortality are not fully understood. Infestations of insect pests may also contribute to the process of drought-induced dieback. Tree physiological...

Fall 2012
Variation in xylem structure and function has been extensively studied across different species with a wide taxonomic, geographical and ecological coverage. In contrast, our understanding of how xylem of a single species can adjust to different growing conditions remains limited. In this thesis,...

Fall 2015
Global increases in carbon dioxide have refocused attention on trees as a mechanism for carbon storage. Leaves are vital to this process, serving as both the site of carbon gain and water loss in trees. As transpiration and photosynthesis are inherently linked in leaves, water movement through...

Spring 2019
This dissertation delves into the anatomy and physiology of the phloem plant vascular tissue. Two primary topics are investigated in this thesis: (1) The cellular localization and response of aquaporin protein water channels in phloem sieve tubes and (2) the mathematical modeling of phloem sieve...

Fall 2023
Arsenic is a highly toxic and ubiquitous element. To this day, millions of people are exposed to arsenic contamination, which poses global health concerns. Phytoextraction performed with willows, a form of phytoremediation, is a promising means of cleaning up soils containing hazardous levels of...
