Ecology of reptiles and amphibians, especially population ecology and life histories of snakes.
In its broadest terms, my research program is concerned with understanding the ecology of amphibians and reptiles, especially temperate-zone snakes. I am interested in these taxa both as unique organisms and as "models" to address questions of more general ecological and evolutionary significance (e.g. life-history theory). An underlying theme in my current research is the question of how environmental and organismal characteristics interact to constrain and shape life histories.
The current and developing work in my laboratory falls into three major categories:
- Movement ecology and habitat use of amphibians and reptiles. Some of this work is explicitly conservation oriented, but it also provides relevant natural-history context for other types of studies such as those below.
- Life-histories of squamate reptiles. This work, in both field and laboratory, goes hand-in-hand with long-term studies of population dynamics and covers three main areas: (a) behavioural and energetic costs of reproduction and "tradeoffs" between traits; (b) factors influencing reproductive success of individuals; (c) the influence of reproductive mode on other life-history traits.
- Feeding ecology of snakes. I am especially interested in how size and type of prey varies between different classes in the population, especially age/size classes and reproductive vs. non-reproductive females, and the consequences of such variation for population dynamics and the expression of life-history traits.
