Environmental DNA barcoding as a method of amphibian species detection compared to conventional monitoring techniques in southern Ontario vernal pools
(University of Waterloo, 2024-03-06)Ongoing monitoring is vital for the conservation of amphibian species and is conducted through conventional auditory and visual surveys. A molecular method, termed environmental DNA (eDNA) barcoding, may offer a more ... -
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 ... -
Transcriptional regulation of North American wood frog (Rana sylvatica) dorsal skin during development and in response to chronic exposure to a microplastics mixture
(University of Waterloo, 2024-02-09)Amphibian populations have been experiencing declines globally for decades due to factors such as habitat loss, invasive species, climate change, overexploitation, pollution, and disease. Skin is an important immune organ ... -
High-throughput OpenArray™: novel, swift TaqMan® Real-Time PCR chip for diagnostic biomarkers in Oncorhynchus tshawytscha
(University of Waterloo, 2024-01-26)In 2014, aquaculture replaced capture fisheries as the primary source of fish supply for human consumption for the first time in history, but to date, fish domestication has not developed enough to cope with the ... -
Microbial Community Compositional Stability in Agricultural Soils During Freeze-Thaw and Fertilizer Stress
(University of Waterloo, 2024-01-22)Microbial activity persists in cold region agricultural soils during the fall, winter, and spring (i.e., non-growing season) and frozen condition, with peak activity during thaw events. Climate change is expected to change ... -
Characterization of Novel Protease Flagellinolysin in Pseudoalteromonas tunicata
(University of Waterloo, 2024-01-03)Flagellinolysins are a family of novel enzymes that act both as structural flagellins and proteases. Although previously identified and shown to be both structurally integrated into filaments and proteolytically active, ... -
Assessing the utility of passive sampling for building-scale SARS-CoV-2 wastewater-based surveillance to inform public health action
(University of Waterloo, 2023-12-21)Wastewater-based surveillance (WBS) is an effective public health tool that has been used to detect human viruses for decades. Most recently it has been applied to monitor SARS-CoV-2 RNA in municipal wastewater to track ... -
Analysis of Cyanobacteria and its Abundance in the Turkey Lakes Watershed using Molecular Techniques
(University of Waterloo, 2023-12-21)Toxic cyanobacterial blooms continue to pose a threat to the quality and safety of drinking water globally by producing toxins and forming dense surface blooms. Forested watersheds naturally provide high quality drinking ... -
Comparative analysis and visualization of microbial gene neighborhoods: applications to pathogen genomics
(University of Waterloo, 2023-12-20)Gene neighborhoods are clusters of genes that are encoded together within the same genomic region, and may share similarity in expression and/or function. Bioinformatic analysis of gene neighborhoods is a powerful approach ... -
Application of Environmental Metabolomics for Assessment of Aquatic Invertebrate Sensitivity to Naphthenic Acids
(University of Waterloo, 2023-12-14)Naphthenic acids (NAs) are a class of chemicals found in oil sands process waters (OSPW) from the extraction of bitumen from surface mined oil sand. In Alberta, Canada, OSPW is currently stored indefinitely in tailing ponds ... -
Algal priming mediates the effects of light and nutrients on organic matter processing: insights from artificial and natural streams
(University of Waterloo, 2023-10-31)Environmental factors such as light and nutrients may play important roles in determining detrital decomposition through their effects on primary production. Thus, human activities that alter the availabilities of light ... -
An investigation into marine environments in the eastern Canadian Arctic
(University of Waterloo, 2023-10-20)Arctic marine environments are especially vulnerable to climate change, but detailed scientific data for these ecosystems are lacking due to their remote location and the associated logistical challenges of conducting ... -
Targeting p62 Palmitoylation as a Potential Therapeutic Strategy towards Huntington Disease
(University of Waterloo, 2023-10-18)Huntington’s Disease (HD) is a neurodegenerative disorder caused by a mutation in the huntingtin gene leading to the accumulation of mutant huntingtin (mHTT) protein and disruption of many cellular pathways causing neuronal ... -
Community-partnered research on subsistence char fisheries near Kugluktuk, Nunavut: novel insights from traditional knowledge and western science
(University of Waterloo, 2023-09-26)Arctic char (Salvelinus alpinus) and Dolly Varden (S. malma) are the two most closely related species in the genus Salvelinus. Both species show substantial intraspecific variation in ecology, life history, morphology, and ... -
Phosphorus cycling by stream biofilms exposed to continuous and episodic loading patterns
(University of Waterloo, 2023-09-25)Anthropogenic activities have led to nutrient enrichment of streams, causing eutrophication of water bodies on a global scale. Eutrophication is frequently tied to an excessive influx of phosphorus (P); a crucial nutrient ... -
PACAP Analogues with Potential Applications in Finfish Aquaculture
(University of Waterloo, 2023-09-25)Global aquaculture industry has significant losses each year due to disease outbreaks, parasitic, viral, and bacterial infections. Common methods to treat fish infections include antibiotics, but prolonged use can lead to ... -
