Fall 2016
Primates play an important role in the maintenance and functioning of tropical ecosystems. However, habitat loss due to land use conversion threatens the persistence of primates worldwide. Colombia has a diverse fauna of primates with 12% of its terrestrial territory protected under the country’s...

Spring 2015
This two papers thesis explores the economics of hybrid poplar plantations as a potential bioethanol feedstock in Canada. The first paper (Chapter 2) is the stand-level analysis of the financial viability of producing hybrid poplar on private lands for both single-stem and coppice production...

Fall 2018
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...

Evaluating trembling aspen seedling stock characteristics in response to outplanting and competition
DownloadFall 2017
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...

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...

Factors affecting larval growth and development of the boreal chorus frog Pseudacris maculata
DownloadFall 2010
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...

Spring 2014
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...

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...

Intermediation and Governance of Digital Flows: Canadian Internet Service Providers as Instruments of Public Policy
DownloadSpring 2018
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...

Introduction of Competition in Regulated Markets: Analysis of Colombia’s Natural Gas Industry
DownloadFall 2016
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...
