Wood frogs (Rana sylvatica) were frozen to -2.5 degrees C under five distinct cooling regimes to investigate the effect of cooling rate on survival. Frogs survived freezing when cooled at -0.16 degrees C.h-1 or -0.18 degrees C.h-1, but mortality resulted at higher rates (-0.30 degrees C.h-1, -1.03 d

โฆ Synopsis
This study assessed the effect of temperature on the potency of carbaryl using tadpoles of Rana clamitans. Temperature, chemical concentration, and the interaction of temperature and chemical significantly affected survival. Generally, increased temperature resulted in lower survival. This study suggests a range of temperatures realistic for a species should be used in toxicity tests.
