However, we find that these extreme isotopic fractionations should be attributed to the poor constraints in DIC carbon isotope ratios instead of the coccolithophores’ physiological response to <i>p</i>CO<sub>2</sub>. More careful measurements of DIC carbon isotope would benefit data interpretations and comparisons in future laboratory culture works focusing on phytoplankton’s response to ocean acidification.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Re-examining extreme carbon isotope fractionation in the coccolithophore <i>Ochrosphaera neapolitana</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-16 01:33:36.760593","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2022-12-22","DateCreate":"2022-12-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000969735000010","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41467-022-35109-4"},"refs":null,"anarec":{"AnaID":359804,"PubliDate":2022,"Pagination":"7606","XtraPublOfAnaID":null,"ISBN":null,"Volume":"13","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":198717,"SerRR":"Nature Communications.
