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...

Afforestation and stand age affected soil respiration and net ecosystem productivity in hybrid poplar plantations in central Alberta, Canada
DownloadFall 2010
Afforestation and stand development can significantly affect soil respiration and net ecosystem productivity (NEP). I studied 1) the effects of afforestation on NEP by comparing cropland previously planted to barley (on a barley-barley-alfalfa-alfalfa-alfalfa rotation) and that converted to a...

To overcome the challenges of low recovery of fine particles in flotation processes, designing a cavitating device that can enhance the recovery has been a major topic of study. In the design of a cavitating device, the bubble/bubble interactions, bubble response to the change of local pressure,...

Competition Impacts on Hybrid Poplar and Implications for Alternative Establishment Systems
DownloadSpring 2015
The effects of different vegetation control practices on tree-weed interactions and associated establishment and early tree growth were investigated in 1-3 year old hybrid poplar plantations containing Walker poplar (Populus deltoides x (P. laurifolia x P. nigra)) and its progeny Okanese poplar...

Ductile and brittle failure behaviors of semi-crystalline polymers such as high density polyethylene (HDPE) were investigated under uni-axial tensile loading at various test conditions. The first part of the thesis examines the influence of aspect ratio of rectangular cross-section on the...

This two papers thesis explores the economics of hybrid poplar plantations as a potential bioethanol feedstock in Canada. The first paper (Chapter 2) is the stand-level analysis of the financial viability of producing hybrid poplar on private lands for both single-stem and coppice production...

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,...

Hybrid poplar plantations have the potential to produce large amounts of biomass for the forest industry, but the young trees are sensitive to competition. This research attempted to quantify the influence of factors regulating competition in hybrid poplar plantations under four years old. The...

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....
