Microbial community diversity within the subterranean and surface water regimes. a 16S rRNA amplicon sequence community analysis. Functional groupings are based on the presence of sequences shared by microbes that mediate the associated function. “Multiple” indicates there was no specific function associated with the closest match type strain. The majority of sequences were from bacteria and archaea capable of utilizing a variety of complex organic compounds (“Others”; see Supplementary Fig. 4 for further details). For a comprehensive phylogenetic listing and relative abundance of sequence reads see Supplementary Data 2. b Respiratory quinones relative abundance, concentrations, and metabolic affiliations. Quinone nomenclature (UQ m:n ) after Elling et al.35, where Q indicates headgroup type, m number of isoprenoid units in the side chain, and n number of double bonds. MBW, meteoric brackish water; MFW, meteoric freshwater; POOL, cenote pool; SEA, coastal sea; SGW, saline groundwater
