Phylogenetic tree of core taxa in groundwater. The colors in the innermost ring indicate taxonomic information on core taxa at class level. On ring b 1 , black indicates a representative strain matched at the >= 97% similarity level, and gray indicates taxa identified as having uncultured lineage. The colors on rings b 2 and b 3 denote environmental preference. The histogram (b 4 ) in the outermost ring displays average relative abundance
