Fig 2. Principal coordinate analysis (PCoA) based on an OTUs matrix obtained in sequencing 16S (rRNA) through the Ion torrent platform.

Fig 2

Groups based on the Bray-Curtis algorithm. 100A: A. mangium in a monospecific plantation system; A(A+E): mixed plantation of A. mangium and E. grandis with sampling at the Acacia base; 100E: E. grandis in a monospecific system; and E(A+E): mixed plantation of A. mangium and E. grandis with sampling at the Eucalyptus tree base. (A) refers to a total PCoA including all soil layers (0 to 800 cm) and all treatments; (B) refers to a soil layer depth between 0 and 100 cm, whereas (C) evaluates between 100 and 300 cm, (D) between 300 and 500 cm, (E) between500 and 700 cm and (F) from700 to 800 cm.
