Fig 1. Abundance (n = 3) of the 16S rRNA gene.
Treatments: 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 plantation system); and E(A+E) (plantation of A. mangium and E. grandis, with sampling at the Eucalyptus base). Asterisks indicate significant differences (p<0.05) between treatments.
