Relative abundance of different taxonomic groups represented within the (a,b) prokaryotic 16S-V4 sequences, and (c,d) fungal ITS2 sequences. Taxa are clustered at the (a,c) phylum and (b,d) genus levels. Low abundance taxa, defined as those below 1% abundance in all sample groups, are grouped together. Identifications are based on the RDP database for prokaryotes and the UNITE ITS database for fungi.
