Fagan, W. F., Jin, Y., Bishop, J. G., Marleau, J. M., Lewis, Mark A.
The relative importance of plant facilitation and competition during primary succession depends on the development of ecosystem nutrient pools, yet the interaction of these processes remains poorly understood. To explore how these mechanisms interact to drive successional dynamics, we devised a...

Fall 2013
Species invasions are increasing worldwide and are impacting populations, communities, and ecosystems. Non-native species that are ecosystem engineers, such as earthworms, may be particularly likely to have large impacts due to their ability to modify both biological and physical characteristics...

We examined the relationship between aspen cover and understory production across two topographic positions and two management systems within the Aspen Parkland of eastern Alberta. Understory biomass typically declined with increasing overstory, with greater yield losses on north-facing forests...

Changes in peatland plant community composition and stand structure due to road induced flooding and desiccation
DownloadFall 2017
Roads built through peatlands with horizontal water flow can to act as dams that affect local hydrology and thus vegetation composition and structure. On the ‘upstream’ side of roads, soils can become waterlogged causing either increased tree mortality, or stunted tree growth; conversely, the...

Thompson, S. Leigh, Rogow, Faith
This toolkit is based on a belief in the power of human connection and the possibilities of using DISCLOSURE to strengthen that connection. Through dialogue and action undertaken in a spirit of openness and respect, we increase understanding and expand our thinking. We embrace listening, along...

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...

Spring 2014
The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

Inquiring into the Roles and Responsibilities of Facilitating Loose Parts Play: A Practitioner's Perspective
DownloadSpring 2021
Play, and more specifically unstructured outdoor play, is well-documented as being beneficial, and arguably essential to healthy cognitive, emotional, social and physical development. However, factors such as risk, liability and self-regulation often complicate and deter unstructured outdoor play...
