Figure 3.

Dissimilarity in taxonomic and phylogenetic structure of microbial communities from plankton or animal surfaces. (a) Dominance of 18 prokaryotic classes for animal surface microbiomes (averaged by fish families, Anthozoa genera and other invertebrates' taxa) and for plankton (averaged across all 35 planktonic communities). (b) Microbial communities are plotted on the two first axes of a PCoA computed on W-Unifrac. (c) Intra- and inter-group W-Unifrac. Results based on unrarefied data and on U-Unifrac are provided in electronic supplementary material, SM2-5 and 6.
