Table 2.
Results of global (considering the three layers) and pairwise (considering each pair of layers) PERMANOVA (permutational analysis of variance) and ANOSIM (analysis of similarities) of community level physiological profiles (CLPPs) and OTU-based bacterial, archaeal and fungal community structures found in the studied layers A14 (upper), A16 (intermediate) and A18 (lower). F and R values in bold denote statistical significance (p ≤ 0.05).
