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. Ongoing projects follow from his recent studies documenting extreme freeze tolerance (survival to at least -16°C) in a subarctic population of the wood frog. Of particular interest are the biochemical and molecular mechanisms that prepare these remarkable frogs for the protracted, severe winters they face in Interior Alaska.
