Analysis of the pattern and trend of human genomic variations in the form of single nucleotide polymorphisms (SNPs) and small insertions and deletions (INDELs)
chundi, vinay kumarSingle nucleotide polymorphisms (SNPs) and small insertions/deletions (INDELs) are the most common genetic variations in the human genome. They have been shown to associate with phenotype variation including genetic disease. ... -
Cellular Mechanisms Underlying Retinoic Acid-Induced Growth Cone Guidance During Neuronal Regeneration
Johnson, AlyshaDuring the period of neuronal development, neurons must make correct synaptic connections with their appropriate targets. The intricate connections of the nervous system are established in part by growth cones, located at ... -
ENDOCANNABINOID REGULATION OF ADOLESCENT DEVELOPMENT IN MALE AND FEMALE RATS
Simone, JonathanThe present thesis investigated the contributions of adolescent endocannabinoid signalling to brain and behaviour development in male and female rats. In chapter 2, daily administration of the CB1 antagonist AM251, alone ... -
Engineering Optogenetic Control of Endocytic Recycling: Controlling Rab11 Function in Drosophila melanogaster using Engineered Light-Responsive Nanobodies
Ward, DevinThe regulated transport of materials in cells is an essential function of all living organisms. In eukaryotes, one main family of transport regulators is the Rab GTPases. Rab GTPases utilize GTP to move materials throughout ... -
Exploring Diversified Vineyard Ecological Soil Management Strategies: Impacts of cover cropping, Spanish River Carbonatite, and smooth pigweed (Amaranthus hybridus) interactions on an agroecosystem
VanVolkenburg, HeatherAgroecosystems are one of the most heavily managed ecosystems that provide essential services for human well being. Intense management of agroecosystems has led to global degradation of soil and reduced biodiversity, ... -
Functional antagonism of the mesolimbic dopaminergic system on mesolimbic cholinergic system in the vocal expression of an emotional state
Silkstone, MichaelThe overarching goal of this thesis was to determine if the initiation of a positive emotional state could antagonize the expression of a negative emotional state in rats. The hypothesis of the thesis argued that the ... -
Identification and characterization of polymorphic mobile elements (MEs) in humans
Dahi, ZakiaRetrotransposons are mobile elements (MEs) that propagate in a “copy and paste” fashion in the genomes via RNA intermediates. In the human genome, retrotransposons consist of long terminal repeats (LTRs), long interspersed ... -
Identifying the effect of clone and rootstock on viticultural performance, fruit composition and winemaking potential for Pinot Noir, Chardonnay and Riesling, in Niagara, Ontario.
Barker, AndreaPrevious research globally has demonstrated that the performance of grapevine clone and rootstock combinations on vine performance and fruit quality are region-specific. Consequently, it is imperative for the Ontario wine ... -
Proximate influence on eusocial caste behaviour
Awde, David NQueens and workers of eusocial sweat bee species are morphologically and developmentally similar, which means that each female is capable of behaving as a queen or a worker. However, few females lay eggs and behave as ... -
Reproductive behaviour of male Xylocopa virginica and the influence of body size, nestmates, and siblings on territory defence
Duff, LyndonMales of Xylocopa virginica are territorial like many other bee species. Males interact aggressively to displace other males from territories. Body size is known to influence resource holding potential in many other ... -
Role of Exopolysaccharide in Pantoea agglomerans Interactions with Bacteriophages
Zaprzala, PatrickFire blight is the common name given to a disease caused by phytopathogen, Erwinia amylovora. This pathogen infects plants belonging to the rosaceous family, particularly the commercially grown apple and pear cultivars in ... -
Taste responsiveness and beer behaviour
Small-Kelly, StephanieOrosensory perception strongly influences food and beverage liking and consumption. Variation in the perception of these oral sensations presents an opportunity to conceptualise and commercialise products based on consumers’ ... -
Testosterone’s regulation of the HPA axis differs for adolescent and adult male rats
Zeidan, MostafaStress hormones such as corticosterone (CORT), enables rodents to cope and meet the demands of their environment. In adult male rats, CORT release in response to stressors is dampened by the gonadal hormone testosterone. ... -
Thermal Preference and Habitat Use of Eastern Garter Snakes (Thamnophis sirtalis sirtalis) in a Southern Ontario Peatland
Abney, CurtisGarter snakes are the most widespread reptile in North America. Despite occupying vastly different biogeoclimatic zones across their range, evidence suggests that the thermal preference (Tsel) of garter snakes has not ... -
Utilization of unmanned aerial vehicles and proximal sensing to detect Riesling vineyard variability
Dorin, BriannA single vineyard block can consist of significant spatial variability for several grape-growing attributes. The ability to detect and subsequently respond to this variation can lead to improved vineyard management, a ...
