Biographical Information

Jon Costanzo's research explores the physiological ecology of ectothermic animals inhabiting harsh environments, with primary focus on the overwintering biology of temperate-zone amphibians and reptiles. Costanzo uses field and laboratory approaches to investigate the hibernation physiology and ecology of cold-hardy frogs and turtles. Supported by the National Science Foundation, these studies focus on the roles of supercooling and freeze tolerance in winter survival, physiological aspects of cold hardening, and interactions between the animal and the winter microenvironment.  Costanzo is a full-time researcher who is strongly committed to training undergraduate and graduate students.
