Both sexes were run together in the same CDF analysis to avoid scale effects but mapped separated onto the reconstructed phylogeny (see Figure 6). Values in parenthesis represent the percentage of variance explained by each CV. Statistical significance of Pearson correlation coefficients between the original variables and canonical discriminant function loadings are indicated.

+ Equivalent chainlengths of each hydrocarbon as defined in Table 2.

ns = not significant. * P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.01, ****P ≤ 0.0001.
