  1. Acronyms, numbers of 20 × 20 m plots retained in the analyses for the ITS2 (fungi) and V4 (bacteria) and the corresponding number of samples are presented. The Illumina MiSeq runs are detailed with, run A, samples from Rivière Blanche and Kopéto; run B, samples from Bois du Sud and Tiébaghi; and run C, samples from Goro plateau and Maré island.
  2. *: maquis dominated by Tristaniopsis glauca at Rivière Blanche site.
  3. **: maquis dominated by T. calobuxus and/or T. guillainii at Kopéto site.
