I am interested in the ecological and evolutionary consequences of environmental variation. My research has focused on amphibians because their life history and demography is extremely sensitive to environmental conditions and they live on a spatial and temporal scale that is amenable to comprehensive observational and experimental study.
Out of earlier studies of phenotypic and quantitative genetic variation in larval development, I have developed an integrated study examining individual growth, development, and dispersal, population demography, dynamics and genetic structure, and landscape-level analyses of habitat use in the highly variable and dynamic Prairie Pothole ecosystem. Most of this work has involved the wood frog, Rana sylvatica, and more recently the Northern Leopard Frog, Rana pipiens, and other amphibians found in the region.
My students and I have also examined continental-scale patterns of genetic variation in wood frogs using microsatellite markers, developed microsatellite loci for the Plains spadefoot toad, Spea bombifrons, and investigated the helminth parasite communities (in collaboration with Dr. Vasyl Tkach) found in wood frogs and leopard frogs on the northern plains. Finally, I am interested in the application of scientific knowledge to the conservation of biodiversity. One of my goals is to understand the ways in which human activities alter ecological and evolutionary processes. The Prairie Pothole Region is dominated by agriculture and produces much of the nation's wheat, sunflowers, canola, sugar (beets), and other important crops. Embedded within this landscape are numerous wetlands, along with large expanses of grazing land in some areas.
Prairie wetlands fluctuate in response to the highly variable patterns of temperature and precipitation that characterize the northern plains, and amphibians are therefore exposed to a wide range of landscape and climatic conditions. The region is ideal for investigating the impacts of land use and climate change on a notoriously sensitive group of species.
