A structural investigation of novel fungal polyglycine hydrolases
(University of Waterloo, 2023-03-22)Polyglycine hydrolases (PGH) are a family of fungal proteases that are known to cleave the polyglycine linker of Zea mays chitinase, ChitA, thwarting one mechanism of plant defense against fungal infection. Previously, ... -
Investigating the influence of the transcription factor Hindsight in a Notch-induced tumour model
(University of Waterloo, 2023-01-24)In Drosophila development, the adult salivary gland and hindgut are derived from populations of undifferentiated cells that are found in the larval stages and are known as the salivary gland imaginal ring (SGIR) and hindgut ... -
Reconstruction of past variation in lake water balance at upstream Smoky and Wabasca watersheds to improve understanding of causes of lake drying in the Peace-Athabasca Delta
(University of Waterloo, 2023-01-23)Controversy persists regarding causes of recent lake-level drawdown within the internationally recognized Peace-Athabasca Delta (PAD), northern Alberta. Central to this debate are conflicting interpretations of causes of ... -
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 ... -
Microbial Composition and Functional Diversity in Waste Environments
(University of Waterloo, 2023-01-09)Landfilling remains the most common endpoint of discarded waste. At landfill sites, waste is transformed and degraded by microbially mediated processes conducted by different trophic groups, comprised of members of a ... -
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 ... -
Development and Application of Periphyton-Based Biomonitoring Methods to Elucidate Aquatic Ecosystem Responses of Lakes in a Water-Rich Northern Landscape (Old Crow Flats, Yukon, Canada) to Climate Change
(University of Waterloo, 2022-12-13)Shallow freshwater lakes are abundant in Arctic and subarctic regions, where they provide important wildlife habitat and sustain the cultural heritage and traditional land use of Indigenous communities. Concern over effects ... -
The role of social preferences in the organization of a gregarious mammal colony
(University of Waterloo, 2022-12-02)Social preferences are often demonstrated to exist in “intelligent”, long-lived species, such as cetaceans and primates, where individuals have the opportunity to form relationships with conspecifics through repeated ... -
Seedlings of Temperate Tree Species Show Plastic Responses to Water Deficit and Heat Stress, But They Do Not Prevent Decline in Growth
(University of Waterloo, 2022-10-03)Species response to climate change is difficult to predict because warming involves the interaction of multiple stressors whose effects are simultaneous and therefore difficult to disentangle. To address this gap, I studied ... -
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 ... -
Discovering new viral lineages and estimating their abundance in wastewater
(University of Waterloo, 2022-09-27)Wastewater surveillance of SARS-CoV-2 has emerged as a critical tool for tracking the spread of COVID-19. In addition to estimating the relative case numbers using qPCR, SARS-CoV-2 genomic RNA can be extracted from wastewater ... -
Petabase-scale Data Mining Identifies Novel Clostridial Species and Neurotoxins Associated with Ancient Human DNA
(University of Waterloo, 2022-09-08)Analyzing microbial genomes found in archaeological samples can provide insights into the origins of modern infectious diseases. A large-scale metagenomic analysis of archeological samples discovered bacterial species ... -
An Exploration of the Scope of GPCR to RTK Transactivation in HT22 and SH-SY5Y cells
(University of Waterloo, 2022-09-02)Receptor tyrosine kinase (RTK) transactivation is a mechanism by which G proteincoupled receptor (GPCR) activity induces the activation of an RTK. As separate families of receptors, they were long thought to act ... -
Wetland birds and invasive plant management
(University of Waterloo, 2022-08-31)The Great Lakes coastal wetlands are some of the most diverse ecosystems in Ontario. However, their ecological integrity is continually threatened by development, nutrient pollution, and invasive species. Over the past two ... -
Development and application of paleolimnological analyses to disentangle the roles of natural processes and anthropogenic activities on contaminant deposition and hydrological conditions across a northern delta
(University of Waterloo, 2022-08-29)Freshwater ecosystems across northern Canada provide important habitat for wildlife and have long supported the traditional lifestyles of Indigenous communities. Multiple potential stressors threaten the security of water ... -
Paleohydrology of the Wabasca River and relations with past flood regimes at the downstream Peace-Athabasca Delta
(University of Waterloo, 2022-08-22)The Peace-Athabasca Delta (PAD; northern Alberta) is internationally recognized for its ecological, historical, and cultural significance, yet controversy persists over the roles of hydroelectric regulation of Peace River ... -
Investigating the use of enhancer trapping and Cas9-induced rearrangements to characterize cis-regulatory elements in the Drosophila gene hindsight
(University of Waterloo, 2022-08-22)The gene hindsight (hnt) encodes a transcription factor that is essential for all stages of Drosophila development. Expression of hnt has been observed to promote cell specialization and differentiation of several cell ... -
Using paleolimnology to assess influence of Peace River regulation on lakes along two transects in the northern portion of the Peace-Athabasca Delta
(University of Waterloo, 2022-08-18)The Peace-Athabasca Delta (PAD), northern Alberta, Canada, is an ecologically and culturally important floodplain where debate has persisted for more than 60 years about causes of water-level drawdown of its abundant, ... -
Impacts of wastewater treatment plant effluent and pharmaceutical exposure on innate cytokine expression of darters (Etheostoma spp.) in the Grand River
(University of Waterloo, 2022-08-10)Aquatic organisms, such as fish, are in constant contact with various stressors and antigenic material present within their environments. The impact of stressors associated with wastewater-exposed environments on native ... -
Controls of Fish Mercury Concentrations in Subarctic Lakes of Canada
