The correlation (r) and significance (P) were determined by Mantel tests based on 10,000 permutations between community structure (Bray-Curtis dissimilarity) and environmental variables (Standardized Euclidean distance). Values in bold indicate relative stronger correlation (r) in both bacterial and fungal communities.
