The effect of ecological groupings, of sample sizes (n), of sampling region (sample) and of geographical transect (dist) on the distribution of parameter values estimated from cyt <i>b</i>.

GLM Formula describes the design of each Generalised Linear Model (genetic data were fitted against eco-group, sample size (n), biogeographic provinces (sample) and distance of sampling transect (dist), AICglm1—AIC score for GLM incorporating the eco-group parameter, AICglm0—AIC score of the null model, ΔAIC—difference in AIC values between the two models, P—p value of the ANOVA F test, WMW—provides p-values of Wilcoxon-Mann-Whitney test for differences between pelagic and benthic groups. For the codes of the parameters see Table 2 and for sample sizes see S1 Table.
