Phylogenetic tree of OTUs common to the three mineral substrates based on analysis of 16S rRNA genes (a), 18S rRNA genes (b), and fungal ITS (c). The size of pie charts represents the relative abundance of each OTU, and colors the distribution across mineral substrates (soil in red, banks in green, and inclined planes in blue). Groups of OTUs (i.e., groups 1–34 in a, 1–14 in b, and 1–8 in c) used to compute NRI and NTI values listed in Table S1 are indicated on the outside
