    Name(s): Creator (cre): Bennett, Amanda Maria, Thesis advisor (ths): Murray, Dennis L, Degree committee member (dgc): Burness, Gary, Degree committee member (dgc): Kerr, Leslie, Degree committee member (dgc): Ridgway, Mark, Degree granting institution (dgg): Trent University
    Abstract: <p>Inducible defenses are plastic responses by an organism to the perception of predation risk. This dissertation focuses on three experiments designed to test the hypothesis that plastic ability is limited by energetic constraints. Chapter 1 provides a general introduction to phenotypic plasticity research and the theoretical costs and limitations affecting the expression of plastic traits… more

    Neonatal Environment Influences Behavioural and Physiological Reactivity to Stressors, and Mammary Gland Development in BALB/c Mice: Implications for Breast Cancer Risk

    Name(s): Creator (cre): Kenniphaas, Kyle, Thesis advisor (ths): Kerr, Leslie, Degree committee member (dgc): Kennett, Deborah, Degree committee member (dgc): Saville, Barry, Degree granting institution (dgg): Trent University
    Abstract: <p>Using rodent models, it is possible to study the behavioural and physiological outcomes of early life stress and the influences on normal mammary gland development and carcinogenic risk. Results demonstrate that the experience of three weeks of prolonged maternal separation (LMS; 4 hrs/day) increased the susceptibility of adult, but not pubertal, female BALB/c mice to engage in higher… more
