Typical coastal dune species are mainly restricted to sandy and dynamic habitats [marram dunes, pioneer dune slacks], xerothermic grasslands and moss-dominated dunes. Typical species for salt marshes in our region also occur along the coast. A total of 65 ground and tiger beetle species can therefore be defined as typical for the Flemish maritime region. Of these, more than one third declined significantly, while only two species showed a While on a larger scale, it results in strong genetic differentiation of isolated dune and salt marsh beetle populations. Recent increase in occurrence. We are also conducting long term studies on diversity, population dynamics and ecological and genetic effects of habitat fragmentation on carabid beetles in coastal dunes and salt marshes. Apparently a high year-to-year species turnover exists in the coastal dunes, in which about half of the species can be categorized as migrants. Typical species remain present, although their population density shows strong fluctuations between years. Habitat fragmentation encourages the invasion of non-typical species.","AbstractOtherLang":"Zandloop- en loopkevers behoren tot de meest populaire, soortenrijke en best bestudeerde ongewervelden, ook in Vlaanderen. Typische soorten voor de kustduinen zijn vooral gebonden aan zandige dynamische habitats [helmduinen, heel jonge duinpannen] en aan droge graslanden en mosduinen [grijze duinen]. Stenotope soorten van schorren komen eveneens langs de kust voor. In totaal kunnen aldus 65 loopkeversoorten gekarakteriseerd worden als specifiek voor de duinregio. E~n derde van deze soorten gaat recent significant achteruit, terwijl slechts twee soorten toenemen in Vlaanderen. In de duinstreek voeren we ook langetermijnonderzoek uit naar diversiteit, populatiedynamiek en ecologische en genetiche effecten van habitatfragmentatie. Daaruit blijkt dat een hoge jaar-tot-jaar turnover de loopkevergemeenschappen kenmerkt, en dat de helft van de soorten als migranten getypeerd kunnen worden. Typische soorten blijven aanwezig, hoewel hun densiteit sterke schommelingen kan vertonen tussen jaren. Habitatfragmentatie bevoordeligt de invasie van atypische soorten; op grotere schaal is genetische differentiatie reeds merkbaar.","BibLvlCode":"AMS","StandardTitle":"Loopkevers en zandloopkevers","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":65703,"PubliDate":2004,"Pagination":"252-271","XtraPublOfAnaID":null,"ISBN":"90-403-0205-7","Volume":"22","Issue":null,"BRefMon":65548,"BRefMonRR":"<b>Provoost, S.; Bonte, D.
