Winter Biology & Freeze Tolerance in the Goldenrod Gall Fly
|
Birds migrate. Bears hibernate. Turtles and frogs retreat to the bottom of lakes. Most animals must avoid harsh winter conditions; few can survive freezing. Larvae of the goldenrod gall fly (Eurasia solidaginis), can survive freezing to -40°C or below. The study of survival at low temperature is called cryobiology. This article provides an introduction to the winter biology of this widely distributed and unusual species, and suggests classroom activities that illuminate principles of cryobio...
