Figure 3. Links between key soil functions and plant
and microbial diversity. Correlation (spearman ρ) between five soil
functions and microbial diversity across plant diversity treatments,
measured at (i) pre -drought, (ii) drought, and (iii) after recovery.
Soil functions were correlated against plant species richness and in
individual soil dilution levels. Further, bacterial, and fungal
richness, diversity and composition were correlated with soil functions
in each plant richness level. Significant (p <0.05)
correlations are indicated by *.
