Spring 2010
This research determined if woody debris amendments facilitate land reclamation after oil sands mining. Specifically, it assessed if woody debris affects vegetation cover and richness, woody species survival and abundance, soil nutrients, temperature and water, microbial biomass carbon and...

An Assessment of Intercropping and Fertilization in Cassava - (Manihot esculenta) Based Systems in the Kolli Hills, South India
DownloadSpring 2015
There is much interest in reducing risk, increasing yield and maintaining soil fertility and biodiversity in agriculture. The effects of intercropping cassava (M. esculenta crantz) with beans (Phaseolus spp), millet (E. coracana) or a bean-millet mixture with the use of various soil amendment...

Regional assessment of the effects of land use on water quality: A case study in the Oldman River Basin, Alberta
DownloadFall 2010
Protecting and managing Canadian water resources in the face of growing cumulative effects and non-point source pollution from development (industrial, agricultural, and urban), depends on defensible, scientifically founded, watershed assessments. The objectives of this research were to broadly...

Structure, composition and trophic ecology of forest floor predatory mites (Mesostigmata) from the boreal mixedwood forest of northwestern Alberta
DownloadSpring 2013
The forest floor, including the L, F and H horizons is the habitat for numerous soil fauna whose ecological relationships affect various soil processes. The forest floor is closely associated with stand development in boreal forests, creating distinct biochemical and physical characteristics...

Modelling Short and Long-term Effects of Soil Cover Depth on Tree Growth and Productivity in Reclaimed Landscapes of Northern Alberta
DownloadSpring 2019
Success in establishing productive upland forests on landforms reconstructed using mining waste mainly depends on the cover materials and depth that determine water and nutrient availability for plant growth while mitigating the potential risks or limitations of the substrate that is being...

The root distribution, architecture, transpiration and root sapflow dynamics of mature trembling aspen (Populus tremuloides) growing along a hillslope
DownloadFall 2013
The objectives of this study were to explore comparative controls by atmospheric and belowground variables governing transpiration of trembling aspen (Populus tremuloides) growing along a water limited hillslope. Vertical and horizontal root distribution, intra- and inter-clonal root connections,...

Fall 2013
The Earth’s forests are of great economic, ecological, and social importance, and sustaining them is paramount for mitigating climate change. To successfully sus- tain forests we must understand their internal demographic dynamics and their relationship to climate. In this thesis, I developed...

Fall 2019
The communities of Yukon, Northwest Territories and Nunavut are vulnerable to experience high food [in] security levels when both biophysical and anthropogenic aspects overlap, affecting the access, availability and quality of traditional and market-based food. This research aimed to identify...

Water availability and understory influence on tree growth in reclaimed forest ecosystems, Athabasca oil sands region, Alberta, Canada
DownloadFall 2015
Reclaimed forest ecosystems in the Athabasca oil sands region (AOSR) have limiting factors to growth that can result in poor tree performance, as indicated by stunted growth, foliar discolouration and needle dropping, and ultimately threaten reclamation success. Indicators of reclamation success...
