Abstract: <p>Wild lupine (Lupinus perennis) restoration efforts seek to increase and connect populations, using seeds, to facilitate the recovery of endangered butterflys in Ontario. This study observed plant growth and phytohormone levels of L. albus, L. polyphyllus, and L. perennis through stages of seed development, each with varying strategies in growth and reproductive investment. L. polyphyllus… more Full Text: Exploring reproduction in wild blue lupine (Lupinus perennis) in comparison to L. polyphyllus and L. albus A thesis submitted to the committee of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science in the …

Abstract: <p>Autistic traits are characterized by difficulties with socialization, preference for order, and rigid and repetitive behaviour patterns. This study evaluated the psychometric properties of two measures of autistic traits, the Autism-Spectrum Quotient (AQ) and the Sub-threshold Autistic Trait Questionnaire (SATQ), and their associations with the HEXACO personality framework. The… more Full Text: ARE WE ALL ON THE SPECTRUM?

Abstract: <p>Trait Emotional Intelligence (EI) includes competencies and dispositions related to identifying, understanding, using and managing emotions. Higher trait EI has been implicated in post-secondary success, and better career-related decision-making. However, there is no evidence for whether it predicts the pursuit of post-secondary education (PSE) in emerging adulthood. This study… more Full Text: PREDICTING THE PURSUIT OF POST-SECONDARY EDUCATION: ROLE OF TRAIT EMOTIONAL INTELLIGENCE IN A LONGITUDINAL STUDY A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the …

Abstract: <p>Timber harvest can influence the rate of transfer of organic matter from the terrestrial catchment to streams, which may have both direct and indirect effects on in-stream nutrient pools and dynamics. In the interest of developing sustainable forestry practices, the continued study of the effects of forestry on nutrient dynamics in aquatic systems is paramount, particularly in sensitive… more Full Text: The effects of in-stream woody debris from selective timber harvest on nutrient pools and dynamics within Precambrian Shield streams A Thesis submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of …

Abstract: <p>The amitochondrial protozoan, Giardia intestinalis, encodes four members of the cytochrome b5 (CYTB5) family of heme proteins of unknown function. While homology models can predict the likely fold of these proteins, supporting experimental evidence is lacking. The small size of the cytochromes (~16 kDa) makes them attractive targets for structural analysis by Electron Paramagnetic… more Full Text: NMR and EPR Studies on Cytochrome b5 Isotypes of Giardia intestinalis 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 Trent …

Abstract: <p>The parasitic protist Giardia intestinalis lacks most heme proteins yet encodes a flavohemoglobin (gFlHb) that converts nitric oxide to nitrate and likely protects the cell from nitrosative stress. In this work an antibody raised against gFlHb was used to examine both changes in gFlHb expression levels and intracellular localization in Giardia in response to nitrosative stress. Giardia… more Full Text: FLAVOHEMOGLOBIN EXPRESSION IN GIARIDA INTESTINALIS EXPOSED TO NITROSATIVE STRESS A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science …

Abstract: <p>Chemical cues are used commonly by prey to identify predation risk in aquatic environments. Previous work has indicated that negatively-charged ions of m/z 501 are possibly a kairomone that induces anti-predator responses in tadpoles. This thesis found that this ion species: (i) is produced by injured tadpoles; (ii) exhibits increased spectral intensity with higher tadpole biomass; and (… more Full Text: THE ORIGIN AND ECOLOGICAL FUNCTION OF AN ION INDUCING ANTIPREDATOR BEHAVIOUR IN LITHOBATES TADPOLES 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 …

Abstract: <p>The purpose of this study was to understand the lived experiences of mental health and illness in Kuwait. Twenty-six participants were interviewed, including mental health professionals, family physicians, and service users. Findings suggest that inequality, oppression, and human rights violations may drive mental health issues in Kuwait. However, rather than addressing these factors,… more Full Text: IT‘S A MAD, MAD, MAD, MAD WORLD: A CRITICAL ANALYSIS OF THE PERCEPTIONS AND LIVED EXPERIENCES OF MENTAL HEALTH AND ILLNESS IN KUWAIT.

Abstract: <p>Population cycles are regular fluctuations in population densities, however, in recent years many cycles have begun to disappear. With Canada lynx this dampening has also been seen with decreasing latitude corresponding to an increase in prey diversity. My study investigates the role of alternate prey on the stability of the lynx-hare cycle by first comparing the functional responses of… more Full Text: The third wheel: How red squirrels affect the dynamics of the lynx-snowshoe hare relationship A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of a Master of Science in the Faculty of Arts …
