A total of 124 taxa were found, of which 116 were identified at the species level. They were analyzed based on both taxonomic and substrate affinity classification. Presence/absence analysis revealed that <i>P. oceanica</i>, <i>C. nodosa</i> and <i>Leaf litter</i> were all characterized by a conspicuous number of soft-bottom polychaetes (e.g., <i>Prionospio multibranchiata</i> and <i>Ampharete acutifrons</i>) and crustaceans (e.g., <i>Corophium sextonae</i> and <i>Dynamene bidentatus</i>), also known as detritivores. There were also major differences between the three habitats investigated. Consistent with its structural complexity, <i>P. oceanica</i> showed the highest species richness [<i>E</i>(<i>S</i> <sub>50</sub>)] and the most diversified macrofaunal assemblages, both in terms of taxonomic groups and taxa associated with different substrates. The two seagrasses, however, showed a similar species composition and differed from <i>Leaf litter</i> for the exclusive presence of hard-bottom species (e.g., the tunicate <i>Phallusia fumigata</i>) and seagrass-associated species (e.g., the polychaete <i>Syllis garciai</i> and the decapod <i>Paguristes syrtensis</i>). In contrast, <i>Leaf litter</i> showed the most differences between the habitats, and was characterized by the bivalves <i>Abra alba</i> and <i>Cerastoderma glaucum</i>, not found in seagrass beds, and by <i>Loripes lacteus</i> and <i>Ruditapes decussatus</i>. <i>Leaf litter</i> also had the highest content of organic matter (26.7% ± 1.4) and total organic carbon (10.3% ± 0.4). Our results confirmed the facilitative role of living seagrasses, in particular <i>P. oceanica</i>, as related to their structural complexity, for numerous species from different substrates (e.g., hard bottom species). This study also showed that leaf litter beds act as a particular environment where sediment instability, leaf breakdown, and organic matter enrichment and decomposition strongly influence animal distribution. Finally, our results highlighted the ecological and trophic importance of seagrass-derived detritus and the associated macroinvertebrate detritivores within seagrass-dominated systems.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Comparative analysis of macrofaunal species richness and composition in <i>Posidonia oceanica</i>, <i>Cymodocea nodosa</i> and leaf litter beds","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:31:36.868099","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2008,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2008-01-14","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000253351000009","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00227-007-0881-z"},"refs":null,"anarec":{"AnaID":118680,"PubliDate":2008,"Pagination":"1087-1101","XtraPublOfAnaID":null,"ISBN":null,"Volume":"153","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
