Clear relationships between population or site characteristics and genetic structure are not observed, except for the special position taken by some small populations in both species. The dispersal power of <i>P. chalceus</i> in these small populations is larger than in large populations, suggesting that these populations are unstable and/or young. Small populations, however, do not always show a lower genetic diversity than large populations, as would be expected from genetic drift. Dispersal power in <i>P. chalceus</i> declines with increasing age of saltmarsh, probably due to a continuous emigration of winged individuals. Age and size of saltmarshes, although difficult to study independently, both appear to be important in determining the genetic structure of saltmarsh beetles. A maximal diversity in both parameters is therefore recommended as an optimal nature conservation strategy.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Age and size of European saltmarshes and its population genetic consequences: a case study on two ground beetle species","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1998,"MonPub":null,"DateUpdate":"2021-03-03","DateCreate":"2003-07-31","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":37786,"PubliDate":1998,"Pagination":"142","XtraPublOfAnaID":null,"ISBN":null,"Volume":"65","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44265,"SerRR":"Biologisch Jaarboek (Dodonaea).
