Joseph Bernardo
Ph.D - Duke University - 1991
M.A. - University of Pennsylvania - 1986
B.A. - University of Pennsylvania - 1986
Dr. Bernardo is an evolutionary ecologist who specializes on lungless salamanders. His research centers on the genus Desmognathus, which he uses as a model system to study life history evolution, species interactions, population genetics and speciation. He is also interested more generally in the understanding patterns and conservation of biodiversity of the Southern Appalachian region, a temperate zone Biodiversity Hotspot. He is the founder of the Southern Appalachian Biodiversity Institute (sabionline.org), a non-profit NGO that is dedicated to this mission through various types of education and outreach, including public talks. Finally, he is interested in how to use information about species’ physiological tolerances, and their genetic structure to predict the relative endangerment of different species to global climate change.
Research
Current research focuses on using population genetic and morphological data to delimit cryptic species in several groups of Appalachian salamanders in the genera Desmognathus and Aneides. Other ongoing work is examining species’ physiological properties as determinants of their ecological ranges and their population genetic structure. Other work is examining how to develop operational, objective criteria for assessing relative endangerment of species to climate change. Previous work has examined life history evolution, evolutionary ecology of growth rates, and the evolutionary ecology of maternal effects.
