Fig. 2: Population genetic diversity (GDP) across the plant (green) and animal (purple) kingdom.

A density plot (A) shows the distribution of raw GDP values in plants and animals, with 95% confidence interval error bars of phylum means. Phylum-specific slopes (with 95% confidence intervals derived from the Phylum model; Supplementary Data 5) of the absolute latitude effect (i.e. distance to equator) show that diversity only decreases away from the equator in amphibians and molluscs, and even increases in eudicot plants (B). Non-significant slopes (p-values > 0.05) are transparent. Source data are provided as a Source Data file.
