Effects of temperature on the growth of Arctic charr Salvelinus alpinus in Ungava and Labrador, Canada
(University of Waterloo, 2012-05-01)Arctic surface air temperatures have been warming at twice the global rate, making it one of the most susceptible regions to current climate change. Effects on cold-adapted aquatic species, such as the culturally and ... -
Effects of Temperature on the Proliferation of Human and Fish Lens Epithelial Cells
(University of Waterloo, 2019-08-29)Crystallins are proteins that confer refractive properties to the crystalline lens. All vertebrate lenses contain α- and β-crystallins, and often a third major crystallin. Crystallins can have additional non-refractive ... -
A Functional Study of Major Histocompatibility Expression and Immune Function in Rainbow Trout, (Oncorhynchus mykiss)
(University of Waterloo, 2006)Major Histocompatibility Complex (MHC) receptors serve a critical role in self/non-self recognition through the presentation of peptide antigen to circulating T lymphocytes and are also believed to play a role in mate ... -
Impacts of Low Temperature on the Teleost Immune System
(Multidisciplinary Digital Publishing Institute, 2017-11-22)As poikilothermic vertebrates, fish can experience changes in water temperature, and hence body temperature, as a result of seasonal changes, migration, or efflux of large quantities of effluent into a body of water. ... -
Impacts of temperature on Asian Carp life history and population growth
(University of Waterloo, 2021-12-21)Asian carp (bighead carp, Hypophthalmichthys nobilis; black carp, Mylopharyngodon piceus; grass carp, Ctenopharyngodon idella; and silver carp, H. molitrix) are a group of invasive species predicted to cause ecological 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 ... -
Investigating the impacts of diurnal temperature and venlafaxine exposure in zebrafish
(University of Waterloo, 2023-08-29)Increased intensity and frequency of heat waves is predicted to have detrimental impacts on aquatic organisms. Thermal variability coupled with exposure to xenobiotic stress could place significant strain on the thermal ... -
Landslide Hazard and Climate Change in the Mountain Glacial Environment of Northwest North America
(University of Waterloo, 2017-09-21)The aim of this thesis was to improve the understanding of the complex interactions between climate change and landslide behavior in the periglacial mountain environment of northwest North America. In particular, this ... -
Multi-stressor impacts on fish energetics and stress response: a comparison between lab and field studies
(University of Waterloo, 2017-08-24)Aquatic organisms are continuously exposed to multiple environmental stressors that work cumulatively and synergistically to alter ecosystems. The objective of this study was to investigate the impacts of multiple stressors ... -
Multiple Stressors in the Environment: The Effects of Exposure to an Antidepressant (Venlafaxine) and Increased Temperature on Zebrafish Metabolism
(Multidisciplinary Digital Publishing Institute, 2019-11-19)Aquatic organisms are continuously exposed to multiple environmental stressors working cumulatively to alter ecosystems. Wastewater-dominated environments are often riddled by a myriad of stressors, such as chemical and ... -
The physiological ecology of preparing for and recovering from hibernation in temperate insectivorous bats
(University of Waterloo, 2023-01-12)Temperate insectivorous bats that hibernate must both prepare for and recover from hibernation during times of the year with low resource abundance and low ambient temperatures, resulting in energetic bottlenecks in both ... -
Seasonal and environmental effects on physiological tolerances and gill adaptations of imperilled Eastern Sand Darter (Ammocrypta pellucida)
(University of Waterloo, 2024-02-15)In the absence of accurate biological information, conservation and recovery strategies carry the risk of failing to meet their objectives. Understanding species-specific physiological tolerances is important for several ... -
Studies of Headwater Brook Charr (Salvelinus fontinalis) Populations in Southern Ontario affected by Groundwater Extraction
(University of Waterloo, 2010-01-13)Habitat conditions, use and preference, size-at-age, density and condition were assessed for headwater brook charr (Salvelinus fontinalis) populations in streams in Southern Ontario where water extraction was occurring. ... -
STUDIES ON IMPACT RESISTANCE OF SPECTACLE LENS MATERIALS
(University of Waterloo, 2014-05-01)Introduction: The Canadian Standards Association (CSA) Z94.3-07 ballistic impact test for industrial lenses, tests the ability of a lens material to withstand the impact of a 6.4 mm diameter steel ball travelling at a ... -
Temperatures Experienced by Emerald Ash Borer and Other Wood-boring Beetles in the Under-bark Microclimate
(University of Waterloo, 2011-09-30)Most studies of under-bark microclimate have been restricted to observations of a few coniferous trees in wooded southern latitudes. This limitation is worrying because of emerging wood-boring pests that specialize on ...
