Fig. 5. Activities (mean ± s.e.m.) of cytochrome c oxidase (CCO)
(units g-1 wet tissue) in liver (A), tail muscle (B) and heart (C).
Open boxes indicate cold-acclimation treatment, and solid boxes indicate
warm-acclimation treatment. There are significant interactions between
acclimation treatment and test temperature in liver and heart, but not in
muscle.
