A range-wide common garden experiment of white spruce indicates population differentiation in drought tolerance traits
DownloadFall 2019
In western regions of the Canadian boreal forest, mean annual temperature has increased by 1.5 to 2.5 °C, significantly exceeding the mean global temperature increase. Climate conditions have also become drier and together these climate trends have induced widespread growth reductions, dieback...

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...

Application of SWAT-MODFLOW Software to Evaluate Groundwater-Surface Water Interaction in West-Central Alberta
DownloadFall 2018
Responsible watershed management is emerging as a key issue as humanity continues to place increasing demands on water resources. To meet future demands, it has become imperative that water resources be managed as a holistic system rather than solely focusing on individual aspects....

COARSE WOODY DEBRIS EFFECTS ON BIOGEOCHEMISTRY IN TWO RECONSTRUCTED SOILS IN THE ATHABASCA OIL SANDS REGION IN ALBERTA, CANADA
DownloadFall 2015
Forest floor mineral soil mix (FMM) and peat mineral soil mix (PMM) are cover soils commonly used for land reclamation post open pit oil sands mining in northern Alberta, Canada. While in such land reclamation practices the organic matter comes from the peat material salvaged before land...

Ecophysiology And Carbon Allocation Of Aspen And Balsam Poplar Seedlings In Response To Drought
DownloadFall 2012
Drought-induced forest mortality has been recorded in every forested continent. Although the effect of drought on plant growth, physiology and ecology have been extensively studied in the past, the physiological mechanism leading to plant mortality under drought conditions are far from being...

Effects of drought on Eleusine coracana (L.) Gaertn. (finger millet) and identification of microsatellite markers
DownloadSpring 2014
Finger millet (Eleusine coracana (L.) Gaertn.) is a crop with high nutritional profile cultivated mainly in developing countries. It is an allotetraploid (2n= 4x= 36 chromosomes), that belongs to the Poaceae family and has a genome size of 2509 Mbp. Drought is one amongst other abiotic stresses...

Effects of Root Zone pH, Calcium and Phosphorus Supply on Selected Boreal Forest Plant Species
DownloadSpring 2015
Soil pH is among the major environmental factors affecting plant growth. In the reclaimed areas following open-pit oil sands mining in northeastern Alberta, Canada, the pH of reclaimed soil is commonly higher than 8.0. The optimum range of soil pH for growth and the tolerance of pH extremes...

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 2014
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...
