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...

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...

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...

Legume-grass forage mixes for maximizing yield and competitiveness against weeds in early establishment
DownloadSpring 2010
A field experiment from 2003 to 2005 at two sites examined the impacts of forage species and legume proportion on forage sward production. Grasses generally established rapidly and out-yielded swards high in legume content, although legumes did improve forage quality. Alfalfa was retained at...

Light, wind, and touch influence leaf chemistry and rates of herbivory in Apocynum cannabinum (Apocynaceae)
Download2006-01-01
Cahill, J.F., Ingersoll, C.M., Niesenbaum, R.A.
Simply visiting and manipulating plants in a way consistent with measurement in typical ecological studies influences the amount of leaf herbivory experienced by some plant species. We examined the mechanistic basis for why Apocynum cannabinum is particularly responsive to such visitation and...

Local-Scale Drivers of Spatial Patterns and Demographic Rates of Conifer Species in a Forest Chronosequence in Coastal British Columbia
DownloadSpring 2017
Growth, mortality and recruitment are the fundamental demographic processes driving changes in forest structure and dynamics. Rapid changes observed in many forests globally have imposed serious threats to ecosystem services such as carbon sequestration, biodiversity and hydrology, emphasizing...
