Hence, diet composition of <i>Idotea balthica</i>, <i>Idotea hectica</i> and <i>Cleantis prismatica</i> was studied using a combination of gut contents and stable isotopes analysis. Gut content observations indicate that <i>P. oceanica</i> dead leaves are an important part of the ingested food for the three species, although their tissues are constituted of only a small to medium fraction of <i>P. oceanica</i> carbon. Our results also underlined the potential role of these species in the degradation of <i>P. oceanica</i> litter by mechanically fragmenting the litter and by assimilating a small to medium fraction of carbon. Moreover, we showed that there were considerable inter- and intra-specific differences in diet composition. Diet differed between juveniles and adults for <i>I. balthica</i>. Crustaceans are an important food source for adults of <i>I. balthica</i>, while <i>I. hectica</i> indicated a major contribution of algal material. <i>C. prismatica</i> showed an intermediate diet. This trophic diversity is probably one of the factors allowing these species to coexist in the same biotope.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Trophic diversity of idoteids (Crustacea, Isopoda) inhabiting the <i>Posidonia oceanica</i> litter","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-24 01:31:51.295087","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2010,"MonPub":null,"DateUpdate":"2019-07-30","DateCreate":"2010-06-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000273560200002","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00227-009-1311-1"},"refs":null,"anarec":{"AnaID":196340,"PubliDate":2010,"Pagination":"237-247","XtraPublOfAnaID":null,"ISBN":null,"Volume":"157","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
