This study investigated the effect of endolithic photo-autotrophs on the apical septal extension of the cold-water coral <i>Desmophyllum dianthus</i> at Fjord Comau, southern Chile (42.41°–42.15°S, 72.5°W). The fluorescent staining agent calcein was used to document the linear apical extension of septae for a period of one and a half years between 2006 and 2007. The results showed a severe reduction in extension rates associated with the presence of endolithic photo-autotrophs. Infested individuals grew about half as fast as non-infested polyps with a median value of 1.18 µm day<sup>-1</sup> compared to 2.76 µm day<sup>-1</sup>. Contrary to the initial hypothesis, these results point toward a parasitic relationship between <i>D. dianthus</i> and its endolithic photo-autotrophs potentially impairing coral fitness. However, further data on physiological parameters and other aspects of the calcification process are necessary to confirm these findings.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Rates of apical septal extension of <i>Desmophyllum dianthus</i>: effect of association with endolithic photo-autotrophs","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:31:50.740489","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2015-10-28","DateCreate":"2014-06-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000326048000011","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00227-013-2281-x"},"refs":null,"anarec":{"AnaID":239238,"PubliDate":2013,"Pagination":"2919-2927","XtraPublOfAnaID":null,"ISBN":null,"Volume":"160","Issue":"11","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
