Research

I study the habitat requirements and long-term population trends of pond-breeding amphibians.  I am currently working on projects designed to improve our understanding how both adults and juveniles choose among different suitable upland habitats.  I also study long-term demographic patterns of several species with the goal of improving our ability to distinguish between natural and human-caused population fluctuations.
