Pseudomonas aeruginosa is an opportunistic pathogen that forms chronic biofilm infections in the lungs of cystic fibrosis patients. A major component of the biofilm during these infections is the exopolysaccharide alginate, which is synthesized at the inner membrane as a homopolymer of 1–4-linked...

Determination of biokinetic parameters of wastewater biofilms from oxygen concentration profiles
DownloadFall 2011
The process of scale-up and rational optimization of biofilm processes for effective wastewater treatment and reuse require better understanding of the biokinetic behavior of microorganisms in the biofilms. At present, no fast and accurate methods exist for determining kinetic parameters for...

Microelectrodes can be used for profiling environmental biofilms. Currently there is no sulfate microelectrode available for studying sulfate reduction in biofilms. In this study, a sulfate microelectrode was fabricated and tested in measurement of environmental biofilms for the first time. The...

Different scales of spatial segregation of two species of feather mites on the wings of a passerine bird
Download2011
Mestre, A., Mesquita-Joanes, F., Proctor, H., Monros, J. S.
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 community
DownloadSpring 2021
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 environments
DownloadFall 2021
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 Century
DownloadFall 2015
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 disease
DownloadFall 2010
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...
