These patterns are investigated in the <i>Abra alba</i> community on the Belgian Continental Shelf during nine years (1995 - 2003). During this investigation period, the community tended to return to its orginal state, but it never reached this point. This can be related to the replacement of <i>Spisula subtruncata</i> by <i>Donax vittatus</i> as dominant bivalve after 1997, and possibly as a result of the climatic shift of 1998. The devision of the study period in an unstable (1995-1997) and a more stable period (1999-2003) coincide with the year 1998.Different causes are believed to be responsible for shifts in the community structure during the unstable period, such as mass recruitment of the bivalve <i>Spisula subtruncata</i> (biological cause) and some direct physical causes, like a strong increase of the mud content and temperature fluctuations. All these causes have an effect on the macrobenthic density, diversity and species composition. The mass recruitment of <i>S. subtruncata</i> caused a decrease in the density and diversity of the macrobenthos, whereas the increase of mud content was responsible for a crash of the species richness and macrobenthic density. The cold winter could have been responsible for the slow recovery of the <i>A. alba</i> community after those disturbances. The unstable period was followed by a few years of higher stability (1999 - 2003), characterized by a cyclic seasonal pattern and the dominance of the tube building polychaete <i>Lanice conchilega</i>. The overall seasonal pattern in the study at hand was characterized by high macrobenthic densities in spring and summer, with a decline in autumn towards the end of the winter. Although this cycle differed quantitatively from year-to-year, the general features have been repeated throughout the stable period. The dominance of <i>L. conchilega</i> during the stable period probably had a positive influence on the benthos, due to its habitat structuring characteristics.This study indicates that natural causes could have a drastic impact on the normal year-to-year variability and cyclic seasonal patterns in the marine ecosystem and its ability to recover.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"Long-term variability in the <i>Abra alba</i> community: importance of physical and biological causes","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":null,"Notes":null,"AnaPub":2006,"MonPub":null,"DateUpdate":"2015-06-25","DateCreate":"2006-04-03","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":97559,"PubliDate":2006,"Pagination":"75-91","XtraPublOfAnaID":null,"ISBN":null,"Volume":null,"Issue":null,"BRefMon":97552,"BRefMonRR":"<b>Van Hoey, G.</b> (2006).
