To assess the degree to which differences in habitat chemistry (sulfide, pH/CO2) might impact host and symbiont metabolic activity, Riftia pachyptila tubeworms were collected from habitats with low (H2S < 0.0001 mM) and high (up to 0.7 mM) sulfide concentrations. The elemental sulfur content of the symbiont-containing trophosome organ was lower in specimens collected from the low-sulfide site. Symbiont abundance, RubisCO activity, and trophosome carbon fixation rates were not significantly different for individuals collected from low- versus high-sulfide habitats. Carbonic anhydrase activities were higher in the anterior gas exchange organs of R. pachyptila from the low-sulfide habitat. Despite large differences in habitat chemistry, symbiont abundance and autotrophic potential were consistent, while the host appears to tailor carbonic anhydrase activity to environmental CO2 availability.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Response of hydrothermal vent vestimentiferan <i>Riftia pachyptila</i> to differences in habitat chemistry","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-22 01:31:26.470260","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2012,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2016-05-04","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000299199000017","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00227-011-1821-5"},"refs":null,"anarec":{"AnaID":255515,"PubliDate":2012,"Pagination":"435-442","XtraPublOfAnaID":null,"ISBN":null,"Volume":"159","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
