Extended Data Fig. 3: Site-level relationships in NutNet under (a-f) ambient conditions and (g-l) altered conditions.
From: Dominant species predict plant richness and biomass in global grasslands
The relationship between richness and (a, g) community biomass, and (b, h) absolute biomass of the two most dominant species, and (c, i) relative biomass of the two most dominant species; and (d, j) between relative biomass and absolute biomass of the two most dominant species; and between community level biomass and (e, k) absolute biomass of the two most dominant species, and (f, l) relative biomass of the two most dominant species of each site under ambient and altered conditions (76 sites; each site ≈ 3 blocks; each block ≈ 10 plots). All data were natural log-transformed to improve normality. The black dashed and solid lines indicate that the worldwide relationship is not significant (P > 0.05) and significant (P < 0.05), respectively. Both marginal R2 (R2m) and conditional R2 (R2c) are presented in the figures. All statistical tests are conducted as two-sided.
