Putative biotic interactions for bioregions estimated using co-occurrence network analysis. Bubble plots show the patterns of interaction among and within modules of interaction (i.e. putative biotic interactions) at Class level, ranked in order of contribution to interactions for the top ten interacting Classes. Module connectors are shown by circles and module hubs are shown by triangles. Symbol size denotes relative abundance. Red symbols denote mean level of interaction. Interactions for the whole community in each region are shown in Supplementary Fig. S8. Chord diagrams illustrate major associations between abundant ASVs clustered at genus level. Chord thickness denotes relative strength of associations
