Delile litter by <i>Gammarella fucicola</i> Leach and <i>Gammarus aequicauda</i> Martynov, two dominant detritivore amphipods of the <i>P. oceanica</i> leaf litter. Scanning electron microscope observations indicated that leaf litter is highly colonized by diverse diatoms, bacteria and fungi, which may constitute a potential food source for the litter fauna. Gut content observations demonstrated that these species eat <i>P. oceanica</i> litter, and that this item is an important part of their ingested diet. Stable isotope analyses showed that the species do not experience the same gains from the ingested <i>Posidonia</i>. <i>Gammarella fucicola</i> displayed isotopic values, suggesting a major contribution of algal material (micro- and macro-epiphytes or drift macro-algae). On the other hand, the observed isotopic values of <i>G. aequicauda</i> indicated a more important contribution of <i>P. oceanica</i> carbon. The mixing model used agreed with this view, with a mean contribution of <i>P. oceanica</i> to approximately 50% (range 40-55%) of the assimilated biomass of <i>G. aequicauda</i>. This demonstrated that the two species, suspected to be detritus feeders, display in reality relatively different diets, showing that a certain degree of trophic diversity may exist among the detritivore community of the seagrass litter.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Food sources of two detritivore amphipods associated with the seagrass <i>Posidonia oceanica</i> leaf litter","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":"Mediterranean Sea; mixing model; phytodetritus; seagrass; stable isotopes","OtherDescriptors":null,"Notes":null,"AnaPub":2006,"MonPub":null,"DateUpdate":"2018-08-14","DateCreate":"2006-12-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000242214100005","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/17451000600962797"},"refs":null,"anarec":{"AnaID":106355,"PubliDate":2006,"Pagination":"355-365","XtraPublOfAnaID":null,"ISBN":null,"Volume":"2","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":72882,"SerRR":"Marine Biology Research.
