Values are means ± S.E.M. (N = number of individuals),calculated using the values from each trial.
DGC, discontinuous gas exchange cycle; C, closed; O, open; F, flutter.
The metabolic rate of the continuous gas exchange pattern differed significantly from the cyclic patterns (repeated measures F3,41=6.79, P<0.0008; Tukey's HSD for unequal sample sizes).
Means with the same symbols do not differ significantly.
