Bacterial biogeography of the rare Charitable Research Reserve
(University of Waterloo, 2015-09-30)Soil microbial communities play a dominant role in global biogeochemical cycles, with profound effects on agriculture, ecosystem stability, human health, and global climate. As a result, assessing their biogeographic ... -
Bacterial Chromosome Engineering for Applications in Metabolic Engineering
(University of Waterloo, 2015-10-02)As genetic engineering technologies continue to advance and metabolic engineering projects become more ambitious, the need for chromosome engineering tools is increased. In this thesis, I have described the development of ... -
Bacterial Communities in the Glenmore Reservoir with an emphasis on the Cyanobacteria
(University of Waterloo, 2021-08-30)Lakes and reservoirs play an essential role as a source for freshwater that can be potable after proper treatment, or for irrigation to meet the water needs of the population, industry, and agriculture. However, freshwaters ... -
Bacterial diversity and denitrifier communities in arable soils
(University of Waterloo, 2014-05-21)Agricultural management is essential for achieving optimum crop production and maintaining soil quality. Soil microorganisms are responsible for nutrient cycling and are an important consideration for effective soil ... -
The behavioural ecology of burbot, Lota lota: Diel migrations, spatial behavioural syndromes, and behavioural thermoregulation in a reservoir resident.
(University of Waterloo, 2015-08-21)While the impacts of hydropower development on diadromous and riverine fish species have received considerable attention, the ecology and behaviour of fish species residing in hydropower reservoirs is not well understood. ... -
Benthic macroinvertebrate communities of Lake Simcoe (Ontario, Canada): Investigating an 85 year time-scale
(University of Waterloo, 2013-10-28)Lake Simcoe is the largest inland waterbody in southern Ontario and has been the focus of much scientific study over the past 30 years. Increases in phosphorus loading over the past century have impacted algae and aquatic ... -
Benthic-pelagic coupling and spatial dynamics of nutrient availability for benthic nuisance algae in the rocky nearshore zone of eastern Lake Erie
(University of Waterloo, 2019-09-03)Nuisance Cladophora growth in the nearshore during the summer growing season tends to imply nutrient, particularly phosphorus (P), enrichment in the benthos, especially where there is adequate light and hard substrate that ... -
Best Management Practices for Invasive Phragmites Control
(University of Waterloo, 2017-05-18)The invasion of European Phragmites australis in North America has altered resident species plant assemblages in wetlands and created large monotypic patches. As a response, North American land managers control this invasive ... -
Beta-parvin Mediates Adhesion Receptor Cross-Talk During Xenopus laevis Gastrulation
(University of Waterloo, 2013-09-27)Modulation of cell adhesion is essential to the cell rearrangements that characterize Xenopus gastrulation. The spatial and temporal regulation of cell movement requires a highly coordinated cross-talk between cadherin and ... -
Bio-optical Modeling of Aquatic Photosynthesis in the Laurentian Great Lakes
(University of Waterloo, 2010-05-19)The methodology of phytoplankton production measurements in the Laurentian Great Lakes and other freshwater lakes has remained largely unchanged in the past 40 years. In most studies photosynthesis from a single water ... -
Bioinformatic insights into the diversity and evolution of bacterial toxins
(University of Waterloo, 2020-01-24)Bacterial toxins are a broad category of molecules ranging from small organic compounds and peptides to large multi-domain or multi-meric enzymes. Several important diseases are caused primarily by bacterial toxins including ... -
Bioinformatic Insights into the Impacts of External Stimuli on the Human Airway
(University of Waterloo, 2021-12-21)The airway epithelium represents a critical component of the human lung that helps orchestrate defences against inhaled substances including air pollution, allergens, bacteria, and viruses. To manage these continuous ... -
Biological responses in fish exposed to municipal wastewater treatment plant effluent in situ
(IWA Publishing, 2021-04-16)Effluents from municipal wastewater treatment plants (MWTPs) are complex mixtures of chemicals including endocrine-disrupting compounds (EDCs) and 17α-ethynylestradiol (EE2). The objective of this study was to evaluate ... -
Biological responses in rainbow darter (Etheostoma caeruleum) to changes in municipal wastewater quality in the Grand River
(University of Waterloo, 2017-09-27)This thesis is a synthesis of studies that explore the effects of urbanization on a small-bodied fish species, rainbow darter (Etheostoma caeruleum), in the central Grand River (Ontario, Canada) over time. This watershed ... -
Biophysical Studies of Lipid Membranes and their Interactions with Amyloid Peptides
(University of Waterloo, 2015-06-19)Amyloid beta peptides are known to form amyloid fibrils which are implicated in more than 20 currently incurable neurodegenerative diseases, including Alzheimer’s, Huntington’s and Parkinson’s. The proposed mechanism of ... -
The carbon and nitrogen composition of suspended particulate matter in Lake Erie, selected tributaries, and its outflow
(University of Waterloo, 2005)Since their introduction to Lake Erie, dreissenid mussels may have reengineered the cycling of nutrients in the lake so that the nearshore benthic community intercepts, retains, and recycles greater quantities of nutrients. ... -
Carbon Metabolism and Desiccation Tolerance in the Nitrogen-Fixing Rhizobia Bradyrhizobium japonicum and Sinorhizobium meliloti
(University of Waterloo, 2009-04-22)Most members of the Rhizobiaceae possess single copies of the poly-3-hydroxybutyrate biosynthesis genes, phbA, phbB and phbC. Analysis of the genome sequence of Bradyrhizobium japonicum reveals the presence of five homologues ... -
