Fall 2016
Western North American landscapes are rapidly being transformed by forest die- off caused by mountain pine beetle with implications for plant and soil communities. The mechanisms that drive changes in plant and soil community structure and function, particularly for understory vegetation and the...

Drivers of trembling aspen secondary chemistry and impacts on plant communities in the aspen parkland.
DownloadSpring 2020
Plant secondary chemicals are fundamental mechanisms by which plants interact with their environments, including defending against herbivores, attracting pollinators, altering neighbouring plant fitness or facilitating plant-plant communication. Yet our understanding of the extent to which...

Exploring above- and belowground behavioural responses to nutrients and neighbours in wheat (Triticum aestivum L.)
DownloadSpring 2022
Taking in environmental information and responding in ways that maximize their ability to thrive and reproduce, plants exhibit behaviour through constant changes in biomass development and spatial distribution. Studies aiming to map this behaviour often use model plants like sunflowers and...

Grassland plant community assembly: The role of environmental heterogeneity, evolutionary history, competition, and pollination
DownloadFall 2013
Plant community assembly is not a simple process; any factor that can affect the recruitment or coexistence of individuals can alter the outcome (e.g. nutrients, symbionts). In this thesis, I address a diverse subset of these potential factors, focusing on environmental variation, evolutionary...

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...

Temporal dynamics of plant-soil feedbacks and community consequences during Bromus inermis invasion
DownloadSpring 2021
Invasive plant species often come to dominate the community where they have become introduced, posing a serious threat to plant diversity and ecosystem functions. Yet, the long-term dynamics and impacts of invasive species do not necessarily remain constant and may attenuate over time due to...

Fall 2023
The coexistence of numerous species despite competing for similar resources remains a central paradox within the field of ecology. Differentiation of species interactions with resources and their environment has been proposed as a mechanism by which species reduce competitive interactions, thus...

The impact of defoliation on the root foraging behaviour of sunflower (Heliathus annuus L.)
DownloadSpring 2024
Plants have a remarkable ability to proliferate roots and increase nutrient uptake within nutrient patches in the soil. This behaviour, known as root foraging, describes this ability and what factors may influence or modify this response. It has been observed that plants integrate multiple...
