Hierarchical clustering and cladogram show significant differences between GMQ (A, C) and WGT (B, D) surrounding sediment samples and mineral microcosms. The sub-clusters separated in the clustering trees were identified as “GMQ_group_1”, “GMQ_group_2”, “WGT_sediment”, “WGT_aragonite”, and “WGT_group_1” groups. Colored dots represent the taxa with significant differences in abundance between different successions, and cladogram circles represent the phylogenetic taxa from phylum to order. The yellow node stands for shared features. Only the LDA score > 4 was shown. G, GMQ; W, WGT.
