Ordination showing the first two axes of the PCO analysis. a Symbols represent samples of algae (Alg), chitons (Cht), stony corals (Cor), sea cucumber gut (HlG), sea cucumber mantle (HlX), sediment (Sed), sponge denizens (Den), nudibranch gut (NdG), nudibranch mantle (NdX), flatworms (Plt), soft corals (Sft), sponges (Spo), sea urchins (Urc) and seawater (Wat). Samples from biotopes are connected to group centroids; the figure was produced using the ordispider function in the vegan package. b OTU symbols colour-coded according to their taxonomic assignment to selected phyla: Proteobacteria (Proteo), Chloroflexi (Chloro), Cyanobacteria (Cyanob), Actinobacteria (Actino) and Tenericutes (Teneri). The first two axes explain 22% of the variation in the data set. The circle size of the OTU is proportional to their abundance (number of sequences) as indicated by the symbol legend in the bottom right corner of b. Source data are provided as a Source Data file
