    Island Syndrome and Stress Physiology of Mice in the Genus Peromyscus

    Year: 2017, 2017
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Stewart, Nathan, Thesis advisor (ths): Burness, Gary, Degree committee member (dgc): Bowman, Jeff, Degree committee member (dgc): Schaefer, James, Degree granting institution (dgg): Trent University
    Abstract: <p>Biological differences between island and mainland conspecifics have been well studied, but few studies have addressed differences in stress physiology. Stressors, such as predation and competition for resources, cause the release of glucocorticoids (GCs). Characteristics of island wildlife, called "island syndrome", are attributed to low levels of predators and competitors. I… more

    Stress Axis Function and Regulation in New World Flying Squirrels: An Assessment of Acute Stress Response, Negative Feedback, and the Role of Corticosteroid-binding Globulin

    Year: 2017, 2017
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Desantis, Lanna Marie, Thesis advisor (ths): Bowman, Jeff, Thesis advisor (ths): Burness, Gary, Degree committee member (dgc): Rafferty, Steven, Degree committee member (dgc): Wilson, Paul, Degree committee member (dgc): Boonstra, Rudy, Degree committee member (dgc): Vijayan, Mathilakath M, Degree granting institution (dgg): Trent University
    Abstract: <p>Across vertebrate taxa, the hypothalamic-pituitary-adrenal axis (or the stress axis) is highly conserved, and is central to vertebrate survival because it allows appropriate responses to psychological stressors. Habitat shapes successful physiological and ecological strategies, and to appreciate how individual species respond to stressors in their environment, it is essential to have a… more

    Assessing Canada Lynx Dispersal Across an Elevation Barrier: Genetic Structure in Light of Habitat

    Year: 2017, 2017
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Watt, Cristen Margaret, Thesis advisor (ths): Murray, Dennis L, Degree committee member (dgc): Wilson, Paul J, Degree committee member (dgc): Bowman, Jeff, Degree granting institution (dgg): Trent University
    Abstract: <p>Mountain ranges are often thought to restrict movement of wildlife, yet previous studies evaluating the role of the Rocky Mountains as a dispersal barrier for Canada lynx (Lynx canadensis) have been contradictory. Our study uses neutral microsatellite loci to evaluate the role of the Rocky Mountains as a barrier to gene flow for lynx. Although lynx exhibited low genetic differentiation,… more

    Functional Genetic Diversity in American Mink (Neovison vison)

    Year: 2017, 2017
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Morris, Kimberley Yana, Thesis advisor (ths): Wilson, Paul J, Thesis advisor (ths): Bowman, Jeff, Degree committee member (dgc): Shulte-Hostedde, Albrecht, Degree granting institution (dgg): Trent University
    Abstract: <p>The release of domestic organisms to the wild is considered a threat to </p><p>biodiversity because the introduction of domestic genes through interbreeding can </p><p>negatively impact wild conspecifics via outbreeding and local extinction. In North </p><p>America, captive American mink (Neovison vison) are frequently escaping into the wild, </p… more
