My PhD research examines the interplay between amphibian and reptile ecology, brain development/morphology and behaviour.
Learning is the ability to create or modify behaviours in response to recurring environmental stimuli. Increased learning capacity gives animals the behavioural flexibility to respond to rapidly changing and unstable environmental conditions (e.g., as a result of climate change and translocations). In birds and mammals, a greater ability to learn is correlated with larger relative brain mass. Thus, when dealing with novel environmental challenges, large-brained animals should possess a more diverse suite of behaviours than their small-brained counterparts, potentially resulting in a fitness advantage. Although these benefits suggest that evolution constantly selects for larger brain size, brains are metabolically costly organs and this cost sets the upper limit on brain size. The differential ability of animals to meet the metabolic demands of brain tissue results in the great variation we see in brain morphology and learning ability both among and within species.
The proximate and distal causes of this variation in brain size and thus, learning ability remain poorly understood, especially in amphibians and reptiles. My research aims to identify environmental factors that influence brain morphology and learning behaviour, and the ecological significance of this variation for amphibians and reptiles.
I am currently working on a diverse suite of amphibian and reptile systems including elapid snakes, scincid lizards and of course cane toads.
Coming from the far reaches of North America (Canada), I am also interested in physiological mechanisms that allow certain reptiles to not only survive temperatures well below their optimal body temperatures but thrive in these conditions. My research in this area has focused on temperature dependent distribution of blood in the bodies of Thamnophis spp. snakes.
