The analysis is based on data from more than 170 year-round pitfall samplings from the 1970s onwards. We were able to find indicator species for almost all identified habitats. The assemblages are structured by variation in vegetation structure [succession], atmospheric and soil humidity and the presence of both natural or anthropogenic disturbance. Specific and threatened species are particularly found in salt marshes, marram dunes, grey dunes and young sandy dune slacks. A detailed study on the species-area relationship of spiders in moss dominated dunes and short grasslands indicated that total species numbers do not increase as a function of the patch size. The total number of typical species is, however, higher in larger patches. These results indicate higher edge influences in small patches and the importance of microhabitat variation [which should be higher in large patches] or minimal population size for the presence of characteristic species in these habitat patches.","AbstractOtherLang":"In deze bijdrage bespreken we de gemeenschapsstructuur en het voorkomen van specifieke spinnensoorten in de Vlaamse kustduinen- en schorren. De analyse is gebaseerd op data van meer dan 170 bodemval-jaarvangsten, die plaatsvonden vanaf de jaren '70. Bijna voor alle onderscheiden habitats kunnen indicatoren worden aangeduid.De soortengemeenschap in de duinen wordt gestructureerd door variatie in vegetatieontwikkeling, atmosferische en bodemvochtigheid en de aanwezigheid van zowel antropogene [beheer) als natuurlijke dynamiek [overstuiving]. Vooral schorren, helmduinen, mosduinen, duingraslanden en jonge duinpannen vormen de habitat voor tal van specifieke en bedreigde soorten.Een gedetailleerd onderzoek naar de oppervlakte-diversiteit relatie van spinnen in mosduinen en korte graslanden wijst erop dat het totaal aantal spinnen niet afhankelijk is van de grootte van de habitatvlek, maar wel dat het aantal specifieke soorten stijgt bij grotere oppervlaktes. Deze resultaten wijzen dus op hogere randeffecten in kleine habitatvlekken en het belang van microhabitat-variatie [die logischerwijs hoger is in grotere vlekken] of minimale populatiegroottes voor het voorkomen van karakteristieke soorten.","BibLvlCode":"AMS","StandardTitle":"Spinnen","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"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":2004,"MonPub":null,"DateUpdate":"2012-09-11","DateCreate":"2004-09-03","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":65714,"PubliDate":2004,"Pagination":"320-343","XtraPublOfAnaID":null,"ISBN":"90-403-0205-7","Volume":"22","Issue":null,"BRefMon":65548,"BRefMonRR":"<b>Provoost, S.; Bonte, D.
