Abstract: <p>Introgressive hybridization between northern (Glaucomys sabrinus) and southern flying squirrels (G. volans) has been observed in some areas of Canada and the USA. However, existing molecular markers lack the resolution to discriminate late-generation introgressants and describe the extent to which hybridization influences the Glaucomys gene pool. I report the first North American flying… more Full Text: De novo transcriptome assembly, functional annotation, and SNP discovery in North American flying squirrels (genus Glaucomys) A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of …

Abstract: <p>Media has had a significant influence on how individuals living with and at risk of Human Immunodeficiency Virus (HIV) care for their health. This research builds on previous research to explore the link between HIV related media messaging and HIV related health behaviours using a mixed methods approach. To investigate the access to and perceptions of HIV related media, a sample of 129… more Full Text: ROLE OF MEDIA IN SHAPING PERCEPTIONS OF HIV AND AFFECTING ENGAGEMENT IN HIV CARE A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science …

These decisions relate not only to rare and endangered species but to common and invasive species as well. The development of the broad spatiotemporal extent models that are helpful in examining range fluctuations can be challenging given the lack of data expansive enough to cover the… more Full Text: NEW INTERPRETATIONS FROM OLD DATA: CHANGES IN EXTENT OF OCCURRENCE AND AREA OF OCCUPANCY FOR CANADA LYNX AND SNOWSHOE HARE FROM FUR HARVEST AND MUSEUM RECORDS A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the …

Abstract: <p>Neuroblastoma (NB) has one of the highest mortality rates in pediatric oncology due to relapsed and refractory disease. Current aggressive multi-modal treatments are inhibited by dose-limiting toxicities and are associated with late-effects and secondary malignancies, emphasizing the necessity for novel therapeutics. Uniquely, most NB cells highly express disialoganglioside (GD2) a cell… more Full Text: Evaluation of silver nanoparticles (AgNPs) and anti-GD2AgNP antibody-drug conjugates as novel neuroblastoma therapies A thesis submitted to the Committee of Graduate Studies in Partial Fulfillment of the requirements for the Degree of Master of Science in …

Abstract: <p>Numerous prey taxa employ defensive postures for protection against attack by predators. Defensive postures mitigate predation risk at various stages of the predator-prey sequence, including through crypsis, mimicry, thanatosis, aposematism, and deflection. In terrestrial salamanders, defensive postures may be aposematic, or deflect attacks away from vital body parts and towards the tail… more Full Text: ENDURING ATTACK: DEFENSIVE POSTURE IN TERRESTRIAL SALAMANDERS (GENUS: AMBYSTOMA) AND THEIR PREDATOR-PREY INTERACTIONS ON PELEE ISLAND, CANADA A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree …

Abstract: <p>I assessed how organisms having multiple biotic attributes may have conflicting niche determinants, and whether the realized niche reflects single or multiple attributes. All-female salamanders engage in two biotic states: hybridism and reproductive parasitism. Hybrids should occupy areas transitional to those used by parental species, whereas parasites that engage in competition with… more Full Text: Complex niche determinants in terrestrial salamanders: Does hybridism or reproductive parasitism explain large-scale patterns of distribution?

Abstract: <p>Salamanders are capable of tissue regeneration throughout all life-stages, which requires the dedifferentiation of mature cells to regrow lost tissues. Dedifferentiation is promoted by degradation of the extracellular matrix by matrix metalloproteases, as well as lysosomal degradation of intracellular and cell-surface proteins that mark cells as part of a mature lineage. Salamanders are… more Full Text: CORTICOSTERONE PROMOTES DEVELOPMENT OF CANNIBALISTIC MORPHOLOGY AND INHIBITS TISSUE REGENERATION IN AXOLOTLS (AMBYSTOMA MEXICANUM) A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfilment of the Requirements for the Degree of Master …

Abstract: <p>Cytokinins (CKs) are hormones that promote cell division. During the formation of tumors in the Ustilago maydis-Zea mays pathosystem, the levels of CKs are elevated. Although CK levels are increased, the origins of these CKs have not been determined and it is unclear as to whether they promote the formation of tumors. To determine this, we measured the CK levels, identified CK… more Full Text: CYTOKININ BIOSYNTHESIS, SIGNALING AND TRANSLOCATION DURING THE FORMATION OF TUMORS IN THE Ustilago maydis- Zea mays PATHOSYSTEM A thesis submitted to the Committee of Graduate Studies in partial fulfillment of the requirements for the degree of Master of …
