In Vivo Detection of Trace Organic Contaminants in Fish Using Solid Phase Microextraction
(University of Waterloo, 2010-10-21)The feasibility of using solid phase micro-extraction (SPME) as an in vivo sampling tool for analysis of trace environmental contaminants in fish exposed to municipal wastewater effluents (MWWEs) was validated using ... -
IN VIVO EPIGENETIC STUDY OF HISTONE ACETYLATION ASSOCIATED WITH OBESITY
(University of Waterloo, 2007-10-02)Post translational modifications in histone proteins are transmissible changes that are not coded for in the DNA sequence itself but have a significant affect in the control of gene expression. Eukaryotic transcription is ... -
Indications of benthic macroinvertebrate assemblage recovery following wastewater treatment upgrades in the central Grand River
(University of Waterloo, 2022-09-28)Treated effluent from wastewater treatment plants (WWTPs) can be a source of substantial nutrient and contaminant loading, altering water chemistry and ecological conditions in receiving waters. To meet new regulations and ... -
Influence of Temperature on the Catalytic Function of Phosphoenolpyruvate Carboxykinase
(University of Waterloo, 2019-05-22)Enzymes are well known for their importance in biological systems. One of these enzymes, PEPCK, has been well studied and characterized over the years. Successful catalysis in PEPCK is very dependent on mobile loop elements ... -
Inhibition of Phosphoenolpyruvate Carboxykinase with a 3-Mercaptopicolinic acid Analogue
(University of Waterloo, 2016-09-01)Phosphoenolpyruvate carboxykinase (PEPCK) is the metabolic enzyme that catalyzes the first committed step in gluconeogenesis and glyceroneogensis. More recently, PEPCK has been implicated in the maintenance and establishment ... -
Integration of paleolimnological and contemporary hydroecological analyses to decipher effects of multiple stressors on water-rich northern landscapes
(University of Waterloo, 2015-09-16)Northern freshwater ecosystems provide important habitat and resources which support abundant wildlife and waterfowl populations and the traditional lifestyle of many First Nation communities. However, concerns have been ... -
An integrative study on the controls of mercury (Hg) in the sediments and food webs of thermokarst lakes on the Arctic Coastal Plain of Alaska
(University of Waterloo, 2019-07-26)Arctic freshwater ecosystems are subject to profound climate-driven changes. Air temperatures are rising, leading to changes that include increased primary production and enhanced permafrost degradation. These and other ... -
The interaction of chemicals isolated from municipal wastewater effluent with rainbow trout (Oncorhynchus mykiss) thyroid hormone receptors
(University of Waterloo, 2012-10-30)The normal function of the thyroid hormone (TH) system is essential for growth, development and metabolism in humans as well as in other species. The action of TH is dependent on its binding to thyroid hormone receptors ... -
The interaction of ultraviolet radiation, dissolved organic carbon and primary production by Laurentian Great Lake phytoplankton communities
(University of Waterloo, 2012-01-12)Man-made chemicals are continuing to erode the ozone layer, and recovery of the ozone layer is slow. Therefore aquatic ecosystems are continuing to receive elevated ultraviolet radiation (UVR). The aim of this work was to ... -
Interactions of ciliates with cells and viruses of fish
(University of Waterloo, 2013-01-29)This thesis develops and utilizes in vitro approaches to study ciliate/fish interactions. The thesis is divided into six chapters. Chapter one reviews the literature on culturing ciliates and fish cells. Chapter two develops ... -
An interdisciplinary approach to monitoring the hydroecology of thermokarst lakes in Old Crow Flats, Yukon Territory, Canada
(University of Waterloo, 2012-09-28)Lake-rich thermokarst landscapes, such as Old Crow Flats (OCF) in northern Yukon, Canada have been identified as amongst the most vulnerable to climate change. This has raised concerns of the Vuntut Gwitchin First Nation ... -
Invasive Round Goby (Neogobius melanostomus) impacts on native fishes in tributaries of the Great Lakes
(University of Waterloo, 2022-12-19)Many invasive species have established in the Laurentian Great Lakes basin and have caused substantial impacts to native species and the lacustrine ecosystems within the basin. The establishment of Round Goby (Neogobius ... -
Investigating Cyanobacterial Communities Across Canada and Characterizing the Seasonality of Cyanobacterial Toxin and Nitrogen Metabolism Genes in the Turkey Lakes Watershed Using Metagenomics
(University of Waterloo, 2023-08-08)The long evolutionary history of gram-negative cyanobacteria has enabled them to tolerate extreme conditions, succeed in numerous habitats, and exploit special nutrients, all while resisting harmful anthropogenic and climate ... -
Investigating ER Body Localization and the Splice Variant Function of HOTHEAD in Arabidopsis thaliana
(University of Waterloo, 2020-05-15)Plants live in constantly changing, often unpredictable environments and have evolved diverse strategies to adapt to these changes. The first line of defense for land plants is the cuticle – a layer which covers the epidermis ... -
