My graduate and postdoctoral research focused on the impacts of variations in aquatic and terrestrial habitat quality on pond-breeding amphibians (mostly spotted salamanders and American toads), and was always conceived in a conservation context. I have used a wide range of experimental approaches---from molecular analyses and small-scale behavioral studies to large, landscape-scale field experiments---to study the ecological implications of habitat alteration for amphibians. Past research topics include: the effects of landscape composition on the genetic population structure of salamanders; the importance of aquatic vegetation structure in mediating biotic interactions of pond-breeding amphibians; differential growth, locomotor performance, and survival of larval and juvenile amphibians from shaded and open-canopy ponds; and the importance of wetland hydroperiod and upland forest buffers for vernal pool-breeding amphibians. By observing how populations and communities respond along environmental gradients (e.g., hydroperiod, canopy cover), and in the presence of multiple stressors (e.g., predation pressure, pesticide exposure), we can: (1) deepen our understanding of how systems function and (2) make predictions about how communities will respond to future environmental alterations caused by global climate change and changes in land use.
