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 Full Text: NEONATAL ENVIRONMENT INFLUENCES BEHAVIOURAL AND PHYSIOLOGICAL REACTIVITY TO STRESSORS, AND MAMMARY GLAND DEVELOPMENT IN BALB/c MICE: IMPLICATIONS FOR BREAST CANCER RISK A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfilment of the …

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 Full Text: CONSTRAINTS ON PHENOTYPIC PLASTICITY IN RESPONSE TO PREDATION RISK: CARRYOVER EFFECTS, MATERNAL INVESTMENT, AND THE STARVATION-PREDATION RISK TRADE-OFF A dissertation submitted to the Committee on Graduate Studies in partial fulfillment of the …
