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...

Adamczak, Kateri M.

This paper examines changes in climate with respect to permafrost and engineering design in Arctic regions. Current understanding of climate changes, predictive modeling, and climate data were studied. Inconsistencies and differences were noted, discussed, and evaluated using comparisons of the...

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...

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...

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...

Effective forest management requires reliable growth and yield models and adequate information on changes in the forest resulting from climate change, insect outbreak and competition from neighboring trees. Growth responses of white spruce (Picea glauca (Moench) Voss) and black spruce (Picea...

Inter-annual variability in glacier and ice cap surface mass balance in the Queen Elizabeth Islands (QEI), Arctic Canada, is driven primarily by variability in summer melt. Mean summer (June-August) QEI glacier surface temperatures (LSTs) and shortwave broadband black-sky surface albedo (BSA) are...

The internet has often had a disintermediating effect, 'disrupting' and circumventing traditional middlemen and gatekeepers. This dissertation examines the related trend of intermediation, or the ascendance of new internet intermediaries and their growing significance in our lives. Among these...

This dissertation deals with the introduction of competition in regulated industries such as natural gas. The thesis focuses on the recently developed Colombian natural gas market and uses a more mature market, the deregulated gas market existing in the province of Alberta, Canada, as a benchmark...
