Cryoprotectants and extreme freeze tolerance in a subarctic population of the wood frog.
Costanzo, Jon P.; Reynolds, Alice M.; do Amaral, M. Clara F.; Rosendale, Andrew J.; Lee, Richard LeeWood frogs (Rana sylvatica) exhibit marked geographic variation in freeze tolerance, with subarctic populations tolerating experimental freezing to temperatures at least 10-13 degrees Celsius below the lethal limits for ... -
Identification and expression of a putative facilitative urea transporter in three species of true frogs (Ranidae): implications for terrestrial adaptation.
Rosendale, Andrew J.; Costanzo, Jon P.; Kiss, Andor J.; Lee, Richard E.Urea transporters (UTs) help mediate the transmembrane movement of urea and therefore are likely important in amphibian osmoregulation. Although UTs contribute to urea reabsorption in anuran excretory organs, little is ... -
Seasonality of Freeze Tolerance in a Subarctic Population of the Wood Frog, Rana sylvatica
Costanzo, Jon P.; do Amaral, M. Clara F.; Rosendale, Andrew J.; Lee, Richard E.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 ...
