Note.—Bootstrapped 95% confidence intervals are given in brackets. Age group-specific estimates of diversity measures with significantly different distribution of values, after a Bonferroni correction, when compared with the bootstrap distribution of ARs are denoted with * (actual P values reported in supplementary table S5, Supplementary Material online).
