Fig. 1. Seasonal changes in temperature at a representative microhabitat of larval
Belgica antarctica on Torgersen Island, near Palmer Station,
Antarctica (64°46 S, 64°04 W). Microhabitat temperatures were measured
in 2005–2006 using single-channel temperature loggers. The broken line
indicates the equilibrium freezing point of the body fluids of fully hydrated,
control larvae.
