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...

Spring 2015
Polar bears (Ursus maritimus) enter a period of intensified feeding in the spring, which allows for the accumulation of energy stores critical to surviving the open water season. Study on polar bear predation has been limited by sample size and spatial extent, and hypotheses on the demographic...

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...

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...

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 2010
Competition with weeds decreases crop yields globally. Some traits are known to confer a competitive advantage to spring bread wheat (Triticum aestivum L.), but complex relationships between the competitive traits makes breeding for competitive ability difficult. Prairie organic producers use...

To compete or cooperate? three essays on the relationship between unions and employee and organizational outcomes: the moderating effect of management's response
DownloadFall 2010
In their highly influential work on the labour market impact of unions termed the collective voice/institutional response model (CVIR), Freeman & Medoff (1984) proposed that whether the union’s monopoly or voice face would prevail greatly depended on the union’s and management’s willingness to...
