Fig. 4: Aboveground plant biomass (APB) as a function four pairs of predictors.

From: Interactive and unimodal relationships between plant biomass, abiotic factors, and plant diversity in global grasslands

Fig. 4

The plane presents APB that is predicted by a function containing one quadratic term. The models presented in panels A, C, and D contain a multiplicative interaction among the two predictors. The model in panel B does not contain an interaction. For model summaries see Table 2, and for model comparison see Supplementary Table S1. MAP: Mean annual precipitation, MAT: Mean annual temperature, Clay: soil clay content, Nitrogen: soil total nitrogen content, NDep: atmospheric nitrogen deposition.
