  Willson Lab  






Research in our lab focuses on understanding factors that drive population and community dynamics of reptiles and amphibians including inter- and intra-specific interactions, environmental variation, and anthropogenic impacts such as habitat alteration, pollution, and invasive species. Our work uses a combination of descriptive, experimental, and theoretical approaches to integrate responses from the level of the individual organism to the landscape. Although much of our work is very applied, we are also shedding light on many basic questions in ecology and especially on aspects of reptiles and amphibian biology that set them apart from other vertebrates.

Current projects under investigation in the Willson Lab include:

1) Evaluating population-level effects of anthropogenic stressors (pollution, habitat alteration, climate change) on pond-breeding and stream-dwelling amphibians.

2) Understanding the ecology, impacts, and management of Burmese pythons and other invasive snakes.

3) Assessing interactions between environmental variation (especially drought), prey availability, and density dependence in driving aquatic snake population and community dynamics within wetland ecosystems

Please contact Dr. Willson if you are interested in these questions or are looking for graduate opportunites.
