Relationships between species richness, productivity and spatial variability of productivity. a Relationships between richness and productivity varied among 151 grids with different average productivity or stress gradients in natural grasslands. b Standard deviation (SD) of productivity (i.e., inverse of spatial stability) decreased with species richness in global natural grasslands. Black points and vertical lines show the medians and 95% credible intervals (CI) of productivity variation for each species richness level. Source data are provided as a Source Data file
