  1. Fig. 1

    Relationship between perennial plant species richness and ecosystem multifunctionality (A) measured in a global survey of drylands. Similar relationships for C (B), N (C), and P (D) cycling are shown. Red and green lines are the fitted lines from OLS and SAR regressions, respectively. Results of regressions are as follows: (A) OLS, R2 (percent of variation in multifunctionality explained by the model) = 0.030, P = 0.009; SAR, R2 = 0.022, P = 0.027; (B) OLS, R2 = 0.029, P = 0.011; SAR, R2 = 0.022, P = 0.027; (C) OLS, R2 = 0.018, P = 0.044; SAR, R2 = 0.014, P = 0.082; and (D) OLS, R2 = 0.032, P = 0.008; SAR, R2 = 0.016, P = 0.061.

  2. Fig. 2

    Relative importance of perennial plant species richness (red column) and other predictor variables in models of ecosystem multifunctionality (A) and C (B), N (C), and P (D) cycling. The height of each bar is the sum of the Akaike weights of all models that included the predictor of interest, taking into account the number of models in which each predictor appears. Variable abbreviations are as in Table 1.
