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...

Response competition operates on movement direction and is effector-independent: Evidence from three free choice reaching tasks
DownloadFall 2018
People and other organisms live in complex environments where the number of potential actions is almost always greater than the number of actions that can be performed at a time. Thus, organisms must make decisions about which actions to perform and which to not perform. Theories about how action...

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...

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...

Roots in reconstructed soils - how land reclamation practices affect the development of tree root systems
DownloadSpring 2018
Tree root systems are incredibly complex organs that fulfill several vital functions, the main ones being anchorage and uptake of water and mineral elements. They perform these functions in a highly complex and challenging soil environment with heterogeneously distributed soil resources, physical...

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...

Spatial and Temporal Variations in Tree Growth, Mortality, and Biodiversity in Alberta Forests
DownloadSpring 2014
Understanding the spatial and temporal variation of tree demographic rates and biodiversity is essential for predicting the dynamics of forest ecosystems and their responses to changing environments. This thesis contributes to that understanding through modeling the long-term change in tree...

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...

Spring 2011
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...
