Recent work suggests pHcf homeostasis under short-term exposure to pCO(2) conditions predicted for 2100, but it is still unclear if pHcf homeostasis can be maintained throughout a corals lifetime. At CO2 seeps in Papua New Guinea, massive Porites corals have grown along a natural seawater pH gradient for decades. This natural gradient, ranging from pH 8.1-7.4, provides an ideal platform to determine corals' pH(cf) (using boron isotopes). Porites maintained a similar pH(cf) (similar to 8.24) at both a control (pH 8.1) and seep-influenced site (pH 7.9). Internal pH(cf) was slightly reduced (8.12) at seawater pH 7.6, and decreased to 7.94 at a site with a seawater pH of 7.4. A growth response model based on pH(cf) mirrors the observed distribution patterns of this species in the field. We suggest Porites has the capacity to acclimate after long-time exposure to end-of-century reduced seawater pH conditions and that strong control over pH(cf) represents a key mechanism to persist in future oceans. Only beyond end-of-century pCO(2) conditions do they face their current physiological limit of pH homeostasis and pH(cf) begins to decrease.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Internal pH regulation facilitates in situ long-term acclimation of massive corals to end-of-century carbon dioxide conditions","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-23 01:32:40.521755","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2016-08-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000380975400001","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/srep30688"},"refs":null,"anarec":{"AnaID":260877,"PubliDate":2016,"Pagination":"7 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"6","Issue":"30688","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
