Local-Scale Drivers of Spatial Patterns and Demographic Rates of Conifer Species in a Forest Chronosequence in Coastal British Columbia
DownloadSpring 2017
Growth, mortality and recruitment are the fundamental demographic processes driving changes in forest structure and dynamics. Rapid changes observed in many forests globally have imposed serious threats to ecosystem services such as carbon sequestration, biodiversity and hydrology, emphasizing...

Tree size and tree height are two essential quantities to measure structure and productivity of forest stands. As such, they encourage predictability in changes among tree growth patterns and are fundamental to developing forest management plans. Tree height and size (commonly measured as...

Plant litter: direct and indirect effects of simulated climate change and clipping on its decomposition, and its effects on plant-plant interactions
DownloadFall 2013
Terrestrial ecosystems are characterized by an intricate relationship between plants and soils that influence ecosystem and community level processes and properties. At the ecosystem level, plants (producers) provide organic carbon to the decomposer subsystem and obligate root-associated...

The Canadian Arctic Islands (CAI) contain the largest concentration of terrestrial ice outside of the continental ice sheets. Mass loss from this region has recently increased sharply due to above average summer temperatures. Thus, increasing the understanding of the mechanisms responsible for...

Relationships among diverse root foraging behaviours: understanding plant behavioural types
DownloadSpring 2014
Behaviours capture the functional response of plants to environmental factors. I explore behaviours for twenty co-occurring grassland species in response to common belowground environmental factors (competition, mycorrhizae, heterogeneous and high nutrients) and their relationship to plant...

Role of host identity, stand composition, soil type and disturbance severity in structuring ectomycorrhizal communities in the boreal forest
DownloadSpring 2018
The symbiosis between trees and ectomycorrhizal fungi (EMF) is essential for tree establishment and survival in the boreal forest because it is a disturbance prone ecosystem characterized by long harsh winters and low nutrient mobility. Ectomycorrhizal fungal community composition can be...

Spring 2011
All organisms, including plants, experience variability in the environment which puts pressure on organisms to evolve flexible responses. The study of these responses by organisms falls into the discipline of behavioural ecology. In this thesis, I am interested in the foraging behaviour of plant...

Social Contexts of Environmental Practices: How Sustainable Development Discourses and Trust Mediate the Use of Genomics in the Alberta Beef Industry
DownloadFall 2014
In the face of environmental degradation resulting from beef production, genomics may add to the options available to producers seeking to reduce their environmental impacts. This research seeks to understand cow/calf producer experiences with the environment, the environmental impacts of their...

Fall 2015
The recent open pit mining for oil sands in the Athabasca Oil Sands Region (AOSR), northern Alberta has created an unprecedented industrial scale disturbance whose ecological consequences is not well understood, and requires intensive investigation. This study focused on the temporal dynamics of...

Recent research indicates climate change will be amplified in Polar Regions, which will cause decreases to sea ice thickness and extent throughout the Arctic. Polar bears (Ursus maritimus) will be directly affected by changes to Arctic sea ice conditions because they rely on the ice substrate...
