Sediments ranged fr om silty to very coarse, with the dominant sediment type being silt (33% of all locations). Of the 35 macrobenthic species observed, only seven species occurred in more than 20% of the samples. The polychaete <i>Heteromastus filiformis</i> and Oligochaeta were most common. Multivariate techniques revealed three distinct communities, linked mainly with sedimentological factors: (1) a species-poor (nine species) community with a dominance of the amphipod <i>Bathyporeia pilosa</i>, a low mean abundance and biomass (86 ind/m², 0.0189 g ash-free dry weight (AFDW)/m²), and a mean median grain size of 215 +/- 19 µm (fine sand); (2) a species-rich (22) community, with the small polychaete <i>Polydora ligerica</i> as indicator species, a relatively high mean abundance and biomass (2298 ind/m², 1.395 g AFDW/m², oysters excluded), a mean median grain size of 133 +/- 41 µm, and also the occurrence of sediments with hard substrates being characteristic for this community; (3) a community with an intermediate species richness (12), abundance and biomass (248 ind/m², 0.249 g AFDW/m²), with <i>H. filiformis</i> and Oligochaeta as indicator species, and a median grain size of 76 +/- 9 µm. In the study area several typical brackish water species were observed (e.g. <i>Polydora ligerica, Corophium lacustre, Gammarus salinus</i>). Mean total abundance and biomass were very low, and the benthic communities appeared to be under stress, with a dominance of mainly small, subsurface deposit and surface deposit feeding opportunistic species. This is probably a combined effect of both natural physical and human-induced disturbance. Only sediments with hard substrates (e.g. rocks) seems to favour species richness, providing a shelter against physical disturbance.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"The subtidal macrobenthos in the mesohaline part of the Schelde Estuary (Belgium): influenced by man?","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":null,"OtherDescriptors":"Zoobenthos; Biological stress; Silting; Sediment properties; Community composition; Particle size; Man-induced effects; Salinity effects; Environmental effects; <i>Heteromastus filiformis; Bathyporeia pilosa; Polydora ligerica; Corophium lacustre; Gammarus salinus</i>; ANE, Belgium, Schelde Estuary","Notes":null,"AnaPub":2000,"MonPub":null,"DateUpdate":"2019-09-20","DateCreate":"2011-01-27","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":201885,"PubliDate":2000,"Pagination":"98-110","XtraPublOfAnaID":null,"ISBN":"90-403-0125-5","Volume":"16","Issue":null,"BRefMon":21560,"BRefMonRR":"<b>Ysebaert, T.J.</b> (2000).
