  1. All data are based on a rarefied OTU table at the family level from which chloroplast-affiliated OTUs were removed.
  2. Abbreviations: OTU, operational taxonomic unit; rRNA, ribosomal RNA.
  3. a‘No. of sequences’, ‘OTUs in total’ and ‘Chao estimate’ were calculated from the original non-rarefied OTU data set (including chloroplasts).
  4. b1–3 and 4–28 days represent the number of days after re-introduction on the reef. Data were pooled for each of those two periods.
