My research is directed toward the detection of change in natural systems. This strongly statistical approach to field biology can be applied to a diversity of problems, including the dynamics of Lyme disease, temporal and microgeographic variation in salamanders, and studies on the distribution and abundance of New Hampshire amphibians and reptiles.
The emphasis of the Lyme disease project is on detection of changes in the abundance and behavior of resevoir species (e.g. Peromyscus) as they influence, and are affected by, movement of the disease into new areas.
Salamanders are a useful system for studying the interaction between ecological and evolutionary change. By characterizing salamander populations under different regimes of cooperation for food, I hope to partition the components of phenotypic variation in the shape of their feeding apparatus.
