Nonmetric multidimensional scaling (NDMS) plots of (A) Brothers volcano community composition, (B) functional gene diversity, (C) MAG phylogenetic diversity, and (D) Brothers volcano and ELSC-VFR deep-sea hydrothermal vent community diversity. Plots are based on Bray–Curtis matrices of (A) community composition of Brothers volcano samples constructed from amplicon sequence variants (ASVs) of 16S rRNA gene sequences at a depth of 3,000 sequences per sample; (B) relative abundance of select functional genes and gene categories described in the text (n = 123 genes/gene categories) and shown in Dataset S2B; (C) relative abundance of medium- to high-quality MAGs based on normalized read coverage of taxa assigned by GTDB-Tk (n = 251 taxonomic assignations). Relative abundance data are available in Dataset S3D; and (D) community composition of Brothers volcano and ELSC-VFR hydrothermal vent samples based on ASVs of 16S rRNA gene sequences at a depth of 3,000 sequences per sample. Points closer together on the ordination plot are more similar to each other. The number of samples at each area is indicated as an n value.
