Field transplantation experiments.\r\n\r\n<b>Methodology:</b>\r\n\r\n Electrophoresis (isoelectric focusing and PAGE) of allozymes and radular myoglobins; random amplified polymorphic DNA; development of microsatellite DNA markers and Single Strand Conformation Polymorphisms(SSCP); morphometrics of shell features; ribosomal DNA sequencing (18S rDNA genes and internal transcribed spacers).\r\n\r\nThe population genetic structure of other periwinkle species at various geographical scales and under different  environmental conditions, including contaminant stress, are investigated with the same techniques as outlined above.","AbstractOtherLang":null,"DateLastModified":{"date":"2025-07-02 08:33:20.809226","timezone_type":1,"timezone":"+02:00"},"ParentProID":null,"BeginYear":1992,"EndYear":null,"BMonth":null,"EMonth":null,"BeginMonth":null,"EndMonth":null,"OrigTitleLangCode":null,"OrigTitleLangID":null,"OrigTitleLangNL":null,"OrigTitleLang":null,"OtherAbstractLangCode":null,"OtherAbstractLangID":null,"OtherAbstractLang":null,"OtherAbstractLangNL":null,"Progress":null,"ProgressNL":null,"PublicFlag":1,"CheckedFlag":1,"ND":"2003-11-26","UD":"2007-07-04","DMPFlag":0,"Budget":245000,"BudgetCurrency":"EUR"},"parent":null,"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":null,"ProPartID":108,"PublicFlag":1,"OrigNameLangCode":"en","OrigNameLangID":15,"FullOrigName":"Royal Belgian Institute of Natural Sciences;
