| Abstract: | Seasonal changes in the free glycerol level in body parts of the adult barnacle Balanus balanoides have been followed during the 1969 season. Glycerol levels were highest in winter when the barnacles were most cold-tolerant and lowest in summer when they were least cold-tolerant. It is suggested that glycerol, and possibly other solutes, may be concentrated in the blood of B. balanoides, thus promoting supercooling and reducing the amount of ice formed at sub-zero temperatures. |
