Extended Data Fig. 4: Comparison of β-diversity and its components, as well as the diversity effect within and across ecosystem types.

a-c, Comparison of (a) total β-diversity, (b) variation in species richness and (c) species turnover between sites within the same ecosystem types, as well as between sites across ecosystem types. d, Comparison of the contribution of diversity to variation in ecosystem functioning between study sites within and across ecosystem types. Each pair of dots represents the measures within and across ecosystem types for one of the 22 ecosystem functions. Note that the within-ecosystem comparison for biomass stocks of microorganisms is missing, because data were only available for one replicate per ecosystem type.
