Because only limited information about the acidification effects on isotopic ratios exists in the literature, we provide an assessment of such effects for a wide range of benthic macroinvertebrates from estuarine intertidal sediments with sparse <i>Zostera noltii</i> Hornem. vegetation. Our results revealed only few significant d<sup>13</sup>C shifts for macrobenthos; however, d<sup>13</sup>C decrease after acidification was substantial for several species. We conclude that acidification is not necessary for removing calcium carbonate in a majority of macrobenthos, but we also suggest preliminary testing before deciding it can be omitted. The magnitude of the d<sup>15</sup>N shifts was substantial for some species and variability in d<sup>15</sup>N values of replicate acidified samples exceeded that of non-acidified samples. Therefore, sample acidification should be avoided for d<sup>15</sup>N determination. Moreover, acidification effects vary considerably among species belonging to a single class, rendering generalisations from single-species information potentially spurious.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Sample acidification effects on carbon and nitrogen stable isotope ratios of macrofauna from a <i>Zostera noltii</i> bed","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"decarbonation; inorganic carbon; macrobenthos; sample treatment;seagrass","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2015-10-29","DateCreate":"2014-05-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000322525900007","VABBcode":null,"OpenAcc":0,"DOI":"10.1071/MF12169"},"refs":null,"anarec":{"AnaID":238390,"PubliDate":2013,"Pagination":"741-745","XtraPublOfAnaID":null,"ISBN":null,"Volume":"64","Issue":"8","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":71721,"SerRR":"Marine and Freshwater Research.
