Fig. 3. Supercooling points (SCPs) of Alaska C. clavipes larvae from
summer 2002 to spring 2004. Most are from the vicinity of Fairbanks, except
those collection times identified by an asterisk, which are from near Wiseman.
Black diamonds represent individual SCPs; however, there are numerous
overlapping values. Green squares identify mean SCPs for a given date. Red
squares identify larvae that were cooled to 60°C or 80°C
without expression of a freezing exotherm. Numbers below the red squares
indicate the number of individuals that did not freeze in that particular run.
The red circles show the mean SCP when those individuals that did not freeze
at 80°C were included in the mean calculation, using
80°C as the SCP of these individuals (9 January and 10 March
2004).
