Growth is limited when trees are restricted in resources or they experience conditions outside of their physiological adaptation, such as extreme cold. However, no tree exists in isolation. A variety of aboveground and belowground species interactions modulate the degree to which trees respond to...
Anorexic Affect: Disordered Eating and the Conative Body performs a material feminist re-mapping of the sense events occasioned by self-starvation. Suspending the usual critical interpretations of eating disorders (gender, transcendence, and representation), as well as the clinical rallying...
Assessing the relationships between weather, food limitation and breeding ecology in an Arctic top predatorDownload
A long term project being conducted on a population of Peregrine Falcons (Falco peregrinus) breeding near Rankin Inlet, Nunavut, Canada, has chronicled a steady decline in annual productivity over 30 years. By documenting the direct effects of summer rainfall on nestling mortality, a recent study...
Different scales of spatial segregation of two species of feather mites on the wings of a passerine birdDownload
The \"condition-specific competition hypothesis\" proposes that coexistence of 2 species is possible when spatial or temporal variations in environmental conditions exist and each species responds differently to those conditions. The distribution of different species of feather mites on their...
Disentangling competitive processes to better understand their drivers and consequences in a native grassland communityDownload
Competition is often highlighted as a major force influencing community structure. However, there are multiple facets of competition that may have independent and differential impacts, making the understanding of what drives competition and how it structures communities difficult. In this thesis,...
Disentangling the relative effects of structural complexity and substrate composition on fish habitat selection in coral reef environmentsDownload
Identifying features of biogenic habitats (i.e. made of living plants and animals) that attract and retain resident species is a key theme in ecology with important implications for habitat conservation and restoration. Using corals (class Anthozoa, phylum Cnidaria) —a group of foundational...
Ecological Ideologies of Modernity and Their Temporal-Spatial Representations in Canadian, Russian, and Polish Literatures of the Twentieth CenturyDownload
The dissertation focuses on the temporal-spatial representations of the ecological ideologies of modernity in the writings of Canadian authors Georges Bugnet, Sheila Watson, and Howard O’Hagan, Russian authors Andrei Bitov and Tatiana Tolstaia, and Polish author Czesław Miłosz. The concept of...
Ecology and management of white-tailed deer (Odocoileus virginianus) and mule deer (O. hemionus) of east-central Alberta in relation to chronic wasting diseaseDownload
Chronic wasting disease (CWD) is a fatal pathogen affecting white-tailed and mule deer in east-central Alberta, and I addressed two current limitations of CWD management. First, to improve precision and accuracy of density estimates obtained from aerial surveys, I evaluated alternative survey...
The genetic structure of Escherichia coli is diverse in virulence genes that are required for disease pathogenesis. Stress factors presented in nature, agricultural and food production shape the population structure and drive the acquisition of virulence and resistance genes. Shiga toxin...
