title: Survival of frogs in low temperature.
abstract: Anurans that hibernate at or near the ground surface can survive prolonged exposure to low winter temperatures of northern latitudes by tolerance to freezing. An accumulation of glycerol during winter was correlated with frost tolerance, indicating that this compound is associated with natural tolerance to freezing in a vertebrate.
