Fig. 4. Comparisons of supercooling points (SCPs) of Alaska C. clavipes larvae cooled in contact with ice (red) with those of larvae not in contact with ice (black). Green squares indicate means. Red or black squares indicate larvae that did not freeze at –80°C or –60°C. Green circles indicate means calculated with the inclusion of individuals that did not freeze at –80°C (using –80°C as their SCP).
