Extended Data Fig. 1: Climatic (a) and geographic (b) distribution of 76 experimental sites from NutNet data; and (c) structural equation meta-model to characterize the possible relationships among log(mean absolute biomass of dominant species), log(mean relative biomass of dominant species), log(mean community biomass), and log(mean species richness); and the link between these four variables in the structural equation model and one site-level patterns of (d) cumulative absolute biomass curve and (e) cumulative relative biomass curve taking azi.cn site under ambient conditions as an example.
From: Dominant species predict plant richness and biomass in global grasslands
Here, species-level abundance is estimated based on species-level biomass. The red, gray, and blue dots in Fig. a and b mean that the relationship between log(species richness) and log(community biomass) on the site-level under ambient conditions (year = 0) is significantly positive, non-significant correlated, and significantly negative correlated, respectively (see Extended Data Fig. 3a).
