One potential form of enrichment used in zoos is training animals to perform rides for guests, however, the effect of this activity on the welfare of individual animals has never been examined. I… more Full Text: USE OF SALIVARY CORTISOL TO EVALUATE THE INFLUENCE OF RIDES ON THE STRESS PHYSIOLOGY OF DROMEDARY CAMELS (CAMELUS DROMEDARIUS): VALIDATION OF METHODS AND ASSESSMENT OF SALIVA STORAGE TECHNIQUES A Thesis Submitted to the Committee on Graduate Studies in …

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 …

As a cold-adapted Ice Age relict species, lake trout (Salvelinus namaycush) are ideal for studying potential effects of climate change on coldwater fishes. I studied the thermal acclimation capacity and aerobic… more Full Text: ICE AGE FISH IN A WARMING WORLD: THERMAL ACCLIMATION CAPACITY OF LAKE TROUT (SALVELINUS NAMAYCUSH) POPULATIONS 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>The distribution of animals is rarely random and is affected by various environmental factors. We examined space-use patterns, habitat selection and stress responses of whip-poor-wills to mining exploration activity.To the best of my knowledge, fine scale patterns such as the habitat composition within known home ranges or territories of eastern whip-poor-wills have not been investigated… more Full Text: HOME RANGE USE, HABITAT SELECTION, AND STRESS PHYSIOLOGY OF EASTERN WHIP-‐POOR-‐WILLS (ANTROSTOMUS VOCIFERUS) AT THE NORTHERN EDGE OF THEIR RANGE A Thesis Submitted to the Committee on Graduate Studies in Partial …

Here I used spatial analysis to determine the size of the pollination neighbourhood in a stand of the herbaceous, wind-pollinated plant (<italic>Typha latifolia</italic>;… more Full Text: THE SPATIAL DYNAMICS OF WIND POLLINATION IN BROADLEAF CATTAIL (TYPHA LATIFOLIA): A NEW METHOD TO INFER SPATIAL PATTERNS OF POLLEN DISPERSAL A Thesis Submitted to the Committee on Graduate Studies In Partial Fulfillment of the Requirements for the Degree …
