Appendix A. Tables outlining the number of species and sites included in each of the phylum and refined taxonomic groupings, and similarity indices for pairwise comparisons of refined taxonomic groups at the resolution of 2 and 16 clusters.

TABLE A1. A full list of taxonomic groups for ‘refined’ level analyses, with the number of species present in each group (n.sp.) and the number of sites that contained representatives of that group (n.sites).; This is outlined for the varying degrees of data minimisation: complete community, TC1 (Community truncated to exclude those species found at less than 1% sites), TC2 (excludes species at less than 2% sites), TC4 (excludes species at less than 4% sites), TC6 (excludes species at less than 5% sites).
