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...

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...

An Intersectional Perspective on Experiences Inspiring Transition to University Among First Nations Learners
DownloadFall 2017
The literature on the university participation of First Nations (First Peoples of Canada) learners pointed to historic K 12 challenges and competing demands that hinder their transition to university. Although learners’ attendance is rising steadily, more females than males attend university. ...

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...

American black bears (Ursus americanus) and grizzly bears (U. arctos) have similar habitat requirements, relying on seasonally available grasses, forbs, fruiting shrubs and trees, and neonate ungulates. To avoid aggressive encounters with grizzly bears, black bears partition habitats spatially...

Predictions for climate change include movement of temperature isoclines up to 1000 meters per year, and this is supported by recent empirical studies. This paper considers effects of a rapidly changing environment on competitive outcomes between species. The model is formulated as a system of...

Competition Impacts on Hybrid Poplar and Implications for Alternative Establishment Systems
DownloadSpring 2015
The effects of different vegetation control practices on tree-weed interactions and associated establishment and early tree growth were investigated in 1-3 year old hybrid poplar plantations containing Walker poplar (Populus deltoides x (P. laurifolia x P. nigra)) and its progeny Okanese poplar...

The existing literature debates whether selling, general and administrative (SG&A) spending is on average beneficial to shareholders as an asset-like investment or detrimental to shareholders as the result of empire building. I address this debate by examining the behavior and consequence of SG&A...
