95% confidence limits derived from 10,000 bootstrap resamples of the data (sampling with replacement) are shown in parentheses. Different letters indicate significant differences between continents (ANOVA and subsequent Tukey’s all-pair comparison, P < 0.05). Data for other diversity metrics shown in Supplementary Table 2.
