1-AMINOCYCLOPROPANE-1-CARBOXYLATE (ACC) DEAMINASE GENES IN RHIZOBIA: ISOLATION AND CHARACTERIZATION
(University of Waterloo, 2007-05-14)A collection of 233 putative Rhizobia strains from 30 different sites across Saskatchewan, Canada was assayed for ACC deaminase activity, with 27 of the strains displaying activity. When all 27 strains were characterized ... -
Age Determination and Growth of Rainbow Darter (Etheostoma caeruleum) in the Grand River, Ontario
(University of Waterloo, 2016-05-31)The accurate determination and validation of age is an important tool in fisheries management. Age profiles allow insight into population dynamics, mortality rates and growth rates, which are important factors in many ... -
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 ... -
AlignDx: Enabling Automated, Cloud-Based Workflows for Streamlined Bioinformatic-Focused Pathogen Surveillance
(University of Waterloo, 2023-07-13)The rising trends in infectious disease burden, alongside the recent COVID-19 pandemic, underline the need for effective public health disease mitigation strategies like pathogen surveillance. Improvements to surveillance ... -
Amelioration of Plant Drought Stress by Plant Growth-Promoting Bacteria
(University of Waterloo, 2017-04-28)Plant growth-promoting bacteria (PGPB) that contain the enzyme (1-aminocyclopropane-1-carboxylate) ACC deaminase protect a variety of plants against damage from various biotic and abiotic stresses. Here, the ability of ... -
Ammonia-oxidizing archaea and complete ammonia-oxidizing bacteria in a municipal wastewater treatment plant
(University of Waterloo, 2018-09-25)High levels of ammonia in aquatic environments can lead to eutrophication, oxygen depletion, and toxicity to aquatic animals. An important goal of municipal wastewater treatment plants (WWTPs) is to remove ammonia from ... -
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 ... -
Analysis of heat shock-, sodium arsenite- and proteasome inhibitor-induced heat shock protein gene expression in Xenopus laevis
(University of Waterloo, 2009-05-01)Previous studies have focused on the effect of individual stressors on hsp gene expression in eukaryotic organisms. In the present study, I examined the effect of concurrent low doses of sodium arsenite and mild heat shock ... -
Analysis of Immune System and Stress Parameters of Oncorhynchus mykiss in Response to Juvenile Thermal Preconditioning or Thermal-Based Parental Selection
(University of Waterloo, 2021-09-20)Higher water temperatures and pathogens are both significant factors that negatively affect the welfare of teleost fish. In aquaculture, compared to natural populations, these problems are especially exacerbated, as the ... -
Analysis of premature loss of the extraembryonic Amnioserosa in Drosophila morphogenetic mutants
(University of Waterloo, 2009-01-23)During Drosophila embryogenesis, an extra-embryonic tissue, known as the amnioserosa (AS), is required for the morphogenetic processes of germ band retraction (GBR) and dorsal closure (DC). Being extra-embryonic, the AS ... -
Analysis of Programmed Cell Death in the Amnioserosa, an Extra-embryonic Epithelium in Drosophila melanogaster
(University of Waterloo, 2008-01-24)The amnioserosa (AS) is an epithelium that plays major roles in two crucial morphogenetic processes during Drosophila embryogenesis: Germ Band Retraction (GBR) and Dorsal Closure (DC). The AS is extraembryonic and as such, ... -
Analysis of Temporal Changes in Estrogenic Compounds Released from Municipal Wastewater Treatment Plants
(University of Waterloo, 2019-09-26)Wastewater treatment plants (WWTPs) are traditionally designed to target the removal of contaminants such as total suspended solids, phosphorous, biological oxygen demand, and ammonia. Recent changes to the Federal ... -
Analysis of the structural determinants for voltage-dependent G protein modulation of synaptic Cav2 channels
(University of Waterloo, 2008-08-28)Specialized voltage-gated calcium channels in the Cav2 channel class (such as Cav2.2, N-type) mediate neurotransmitter release from presynaptic nerve terminals. Cav2.2 channels are exquisitely sensitive to inhibition by ... -
Antioxidant Defence Response in Non-Target Fishes Following Pharmaceutical Wastewater Effluent Exposure
(University of Waterloo, 2022-05-05)The Grand River watershed extends throughout the majority of Southern Ontario with its final outlet at Lake Erie and accommodates thirty wastewater treatment plants (WWTP) with varying types and degrees of treatment. ... -
Antiviral responses of Xela DS2 and Xela VS2, two newly established Xenopus laevis skin epithelial-like cell lines, to viral dsRNA and Frog Virus 3
(University of Waterloo, 2019-09-27)There is a current decline in amphibian populations, wherein the emerging pathogen Frog Virus 3 (FV3) is believed to be a proximate cause. The conservation of frog species is thus important as population declines would ... -
The Apparent Partitioning Behaviour of SARS-CoV-2 RNA in Municipal Wastewater
(University of Waterloo, 2023-04-10)The use of wastewater-based surveillance (WBS) has experienced rapid expansion and development since the onset of the coronavirus disease (COVID-19) pandemic that is caused by the virus severe acute respiratory syndrome ... -
Application of artificial substrate samplers to assess enrichment of metals of concern by river floodwaters to lakes across the Peace-Athabasca Delta
(University of Waterloo, 2021-05-19)Potential for downstream delivery of contaminants via Athabasca River floodwaters to lakes of the Peace-Athabasca Delta (PAD), northeastern Alberta (58.6°N, 111.8°W), has raised local to international concern. Prior ... -
