Dr. John Pascarella
Research Description
My lab is interested in topics in plant population and community ecology, including the application of matrix models in the management of rare and endangered species, the evolutionary ecology of hybridization between closely related plant species (in particular Gelsemium and Baptisia), the restoration ecology of forest and wetland ecosystems, and the ecology and conservation of plant-pollinator interactions.
