(a) Seasonal multidimensional scaling diagram of estuary samples, produced with Bray–curtis similarity values for communities that only included estuary-specific OTUs (Stress=0.19). Samples separated into two significantly different communities, early (April–July) and late (August–November) (ANOSIM, P<0.001). (b) Taxonomy of the two seasonal groups. (c, d) Spatial distribution of a top indicator for early (IV: 0.96) and late (IV: 0.87), by average relative abundance, across the ordination of the estuary MDS.
