The luminophores were applied to the sediment surface in 16 m<sup>2</sup> replicated plots, defaunated and control, and left to be reworked by infauna for 32 days. As the macrofaunal assemblage in the ambient sediment and the control plots was dominated by the common cockle <i>Cerastoderma edule</i>, this species was used in an additional mesocosm experiment. The diversity, abundance and biomass of the defaunated macrobenthic assemblage did not return to control values within the experimental period. Both erosion threshold and bed elevation increased in the defaunated plots as a response to the absence of macrofauna and an increase in microphytobenthos growth. In the absence of macrobenthos, we observed an accretion of 7 mm sediment, containing ca. 60% mud. Image analysis of the vertical distribution of the different luminophore size classes showed that the cockles preferentially mobilised fine material from the sediment, thereby rendering it less muddy and effectively increasing the sand: mud ratio. Luminophore profiles and budgets of the mesocosm experiment under “no waves-no current” conditions support the field data very well.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"Sediment segregation by biodiffusing bivalves","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:58:19.190595","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"intertidal; cohesive; sediment; sand; mud; erosion; deposition; luminophores; image analysis; bioturbation; ecosystem engineering; Ecosystem engineering; Intertidal; Intertidaal; Luminophores; Ecosystem engineering; Intertidal; Intertidaal; Luminophores","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2019-08-29","DateCreate":"2009-05-05","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":134904,"PubliDate":2009,"Pagination":"145-174","XtraPublOfAnaID":null,"ISBN":"978-90-902416-6-1","Volume":null,"Issue":null,"BRefMon":134892,"BRefMonRR":"<b>Van Colen, C.</b> (2009).
