Mitigating the Effects of Human Activity on Grizzly Bears (Ursus arctos) in Southwestern Alberta.
DownloadSpring 2015
Anthropogenic habitat loss and alteration, as well as human-caused mortalities associated with increasing access, threaten grizzly bear populations across much of their North American range. This research investigates strategies for mitigating the negative effects of human activities on grizzly...

Modeling the Impacts of Global Change on Tree Growth and Stand Density of Boreal Forests in Canada
DownloadFall 2022
Abstract Global change of environment and human activity has profoundly impacted boreal forests in structure, dynamics and function, imposing serious challenges for maintaining forest growth and yield in Canada. In this thesis, I address three questions important for understanding and predicting...

Modeling the impacts of recent climate change on ecosystem productivity across North America
DownloadFall 2015
There is evidence of warming and changes in precipitation over recent decades in most regions of North America (NA) that are affecting ecosystem productivity. The impacts of these changes on land-atmosphere carbon exchange over a wide range of biomes are spatially heterogeneous and uncertain. In...

Modelling Beneficial Management Practices in Agriculture in Western Canada to Observe Impacts on Greenhouse Gas Emissions and Environmental Sustainability
DownloadSpring 2023
Reducing greenhouse gas (GHG) emissions and other detrimental environmental effects of agriculture is a goal paramount to societal stability and prosperity. Understanding the advantages and constraints of beneficial management practices (BMPs) to the fullest extent in varying conditions is...

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...
