Elevated CO₂ Has Little Influence on the Bacterial Communities Associated With the pH-Tolerant Coral, Massive Porites spp.

ABSTRACT: Ocean acidification (OA) as a result of increased anthropogenic CO₂ input into the atmosphere carries consequences for all ocean life. Low pH can cause a shift in coral-associated microbial communities of pCO₂-sensitive corals, however, it remains unknown whether the microbial community is also influenced in corals known to be more tolerant to high pCO₂/low pH. This study profiles the bacterial communities associated with the tissues of the pCO₂-tolerant coral, massive Porites spp., from two natural CO₂ seep sites in Papua New Guinea. Amplicon sequencing of the hypervariable V3-V4 regions of the 16S rRNA gene revealed that microbial communities remained stable across CO₂ seep sites (pH = 7.44-7.85
