Abstract: <p>The influence of stress exposure on the body temperature of vertebrates has been known for nearly two-thousand years. While the proximate mechanisms supporting this phenomenon are well described, the ultimate mechanisms remain enigmatic. In this thesis, I propose a novel hypothesis which states that changes in body surface temperature (henceforth "surface temperature")… more Full Text: SURFACE TEMPERATURE REGULATION DURING STRESS EXPOSURE: EVIDENCE OF A TRADE-OFF BETWEEN THERMOREGULATION AND THE PHYSIOLOGICAL STRESS RESPONSE IN BIRDS A Dissertation Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements …

Abstract: <p>In endotherms, physiological functioning is optimized within a narrow range of tissue temperatures, meaning that the capacity to dissipate body heat is an important parameter for thermoregulation and organismal performance. Yet, experimental research has found mixed support for the importance of heat dissipation capacity as a constraint on reproductive performance. To investigate the… more Full Text: The effects of heat dissipation capacity on avian physiology and behaviour A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in the Faculty of Arts and Science TRENT …

Abstract: <p>Species ranges are changing and the rate at which the climate is warming is faster than anything previously seen in the past, consequently species will need to adapt quickly, track the climate or perish. Cold adapted terrestrial species are the most vulnerable, because they are limited by the availability of land at the cold edge of their range. This means that many alpine, boreal and… more Full Text: Range dynamics of two closely related felids A dissertation submitted to the Committee on Graduate Studies in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Faculty of Arts and Science Trent University Peterborough, …
