Enzymatic regulation of glycogenolysis in a subarctic population of the wood frog: implications for extreme freeze tolerance
The wood frog, Rana sylvatica, from Interior Alaska survives freezing at –16°C, a temperature 10–13°C below that tolerated by its southern conspecifics. We investigated the hepatic freezing response in this northern phenotype ...
Seasonality of Freeze Tolerance in a Subarctic Population of the Wood Frog, Rana sylvatica
We compared physiological characteristics and responses to experimental freezing and thawing in winter and spring samples of the wood frog, Rana sylvatica, indigenous to Interior Alaska, USA. Whereas winter frogs can survive ...
