Species diversity and functional diversity measures.

Pearson correlations among the considered diversity measurements.
Fric, functional richness; FRao, Rao index.
Fig 1.
The changes of species diversity (a, b and c; n = 9) and functional diversity (d, e and f; n = 9) along the fertilization gradients.
F0, F15, F30, and F60 represent (NH4)2HPO4 fertilizer applications of 0, 15, 30 and 60 g m-2 yr-1. Significant differences indicated by dissimilar letters above each bar were determined using Tukey’s honestly significant difference (HSD) test (P< 0.05) after one-way ANOVA.
Fig 2.
The changes of CWM trait (n = 9) along the fertilization gradients.
CWM, community-weighted mean trait values; SLA, leaf area per unit dry mass; MPH, mature plant height; SS, seed size. F0, F15, F30, and F60 represent (NH4)2HPO4 fertilizer applications of 0, 15, 30 and 60 g m-2 yr-1. Significant differences indicated by dissimilar letters above each bar were determined using Tukey’s honestly significant difference (HSD) test (P< 0.05) after one-way ANOVA.
Fig 3.
The relationships between community biomass (n = 9) and species diversity (a,b and c; n = 9) or functional diversity(d, e and f; n = 9).
R2and P value was estimated from a linear regression model. F0, F15, F30, and F60 represent (NH4)2HPO4 fertilizer applications of 0, 15, 30 and 60 g m-2 yr-1.
Fig 4.
The relationships between community biomass(n = 9) and CWM trait.
R2and P value was estimated from a linear regression model. CWM, community-weighted mean trait values; SLA, leaf area per unit dry mass; MPH, mature plant height; SS, seed size.
