Hierarchical clustering and taxonomic assignment based on ciliate V4 SSU rRNA-amplicons. (a) Hierarchical clustering (Bray-Curtis distance) of sampling sites based on ciliate community profiles in four DHAB halocline interfaces (IF) and brines (B). (b) Taxonomic assignment of ciliate V4 SSU rRNA-amplicons. In total, all amplicons could be assigned to 102 different ciliate genera (closest BLAST match in GenBank nr database) and one unclassified. In the legend of the figure we only show the taxa that are represented by at least 20% of all amplicons in at least one of the eight samples. For further details on taxonomic assignments we refer to Additional file 3: Table S1. M = Medee, T = Tyro, Th = Thetis, U = Urania.
