Fig. 3: Comparison of bacterial and fungal diversity and composition in the three water table-dependent soil layers.

a, c Alpha diversity of bacteria and fungi, defined in terms of the numbers of species observed. b, d Nonmetric multidimensional scaling ordinations of community dissimilarities among three layers, based on Bray-Curtis dissimilarity (f and p represent differences of community composition among layers). e, g Overlap and differences in unweighted numbers of bacterial and fungal OTUs. f, h Relative abundances of bacterial phyla and fungal classes showing >0.5% abundance. Surf surface, Inter interlayer.
