Abbreviations as in Table 1.

For CS and ATPase, results are from ANOVA; LDH was tested with ANCOVA (with body mass as the covariate), as this enzyme varies with body mass(Table 1).

N=217 for ATPase and 315 for CS and LDH; ATPase results exclude the Yarra drainage because of flawed data from Yarra females.
