The research program in my lab draws upon the fields of animal behavior, physiology, ecology, and evolution, and so we almost always take an integrative approach to our questions. We are most interested in animal behavior at multiple spatial and temporal scales and the underlying physiological mechanisms that mediate those behaviors. We are not restricted to any particular taxonomic group, although thus far, most of the experimental studies on behaviour and endocrine mechanisms involve herpetofauna and the landscape-level studies of animal movement ecology focus on mammals.
In our lab, we consider the premise that animals live in a dangerous and challenging world as the driving force behind the types of questions we tackle.
For example, how do animals behaviourally and physiologically adjust to environmental disturbances? Do these macrophysiological patterns and phenotypic trait complexes vary across space and time? Given that most ecological studies of the physiological stress response are still predominantly based on the avian or laboratory mammalian paradigms, I emphasize field studies with reptiles. In doing so, we are able to examine variation in stress responses and phenotypic trait complexes of populations where the social conditions, physical environment, and phylogenetic history generate interesting combinations of selective pressures.
At larger scales, we are also interested in competition, coexistence, and decision making of animals. For example, what landscape-scale movement decisions do African elephants make to maximize resource acquisition and minimize thermoregulatory stress? How do mesocarnivores compete and coexist in human-dominated landscapes? For these kinds of questions, we use movement ecology to determine how animals solve the challenge of sharing a complex and dynamic landscape with other competitors.
