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. ...

Loosen, Anne Elizabeth

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...

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...

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...

In this dissertation, I address 5 problems in the discipline of plant ecology: two problems in plant competition, two problems in plant behaviour and one problem in the phenotyping of plant roots. First, we directly test Darwin’s competition-relatedness hypothesis with a pairwise...

Red alder (Alnus rubra [Bong.]), is the most common hardwood species along the Pacific Northwest coast and is widely distributed as a component of mixed stands with conifers on highly productive sites. It is also a strong competitor in young conifer stands and rapidly overtops associated juvenile...

Trembling aspen is commonly used in the afforestation of boreal forest reclamation sites; however, the presence of vegetation competition can reduce growth and establishment success. This research examines how initial morphological characteristics influence the above and belowground growth of...

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...

Whiting, Arthur V.

The boreal chorus frog (Pseudacris maculata) is a widespread species but we know little of its ecology. I examined the nature and existence of competitive mechanisms operating between larvae of the boreal chorus frog and wood frog (Lithobates sylvaticus) from field, mesocosm and laboratory venues...

Hybrid poplar plantations have the potential to produce large amounts of biomass for the forest industry, but the young trees are sensitive to competition. This research attempted to quantify the influence of factors regulating competition in hybrid poplar plantations under four years old. The...
