{"projectrec":{"ProID":1301,"StandardTitle":"Metapopulation structure and dynamics of estuarine fish","OrigTitle":"Metapopulatiestructuur en dynamiek van estuariene vispopulaties","Acronym":null,"AbstractEnglish":"Estuaries are crucial habitats in the life history of maby species; they are nurseries to juveniles of marine and freshwater fish. Resident species complete their life cycle in estuaries while diadromous species pass estuaries on their way to their spawning  grounds. The community structure in estuaries is highly dependet on migrations of fish between the coastal nurseries and the estuarine feeding grounds. This research projects aims to clarify the spatial and functional role estuaries perform for juvenile marine fish. In particular, we address the question which proportion of estuarine migrants relative to marine residents contribute to the next cohort. In order to be able to do this, fish have to be assigned to populations and habitats, and exchange rates have to be determined. We use stable isotopes to trace migrations and genetic markers to investigate the metapopulation structure.","AbstractOtherLang":"Estuaria zijn cruciale habitats tijdens de levenscyclus van vele vissoorten; het zijn kinderkamers voor de juvenielen van heel wat zee- en zoetwatervissen. Ze herbergen residente vissoorten; diadrome soorten passeren er tijdens hun paaitrek. Bijgevolg wordt de gemeenschapsstructuur in estuaria in sterke mate bepaald door jaarlijks weerkerende migratiegolven van enorme aantallen vissen langsheen de zoet-zout gradiënt. Tot op heden werden slechts hypothesen geformuleerd die het strikte seizoenaal gebruik van estuaria door vissen verklaren. Tegelijk is de impact van deze massale verplaatsingen op de populatiestructuur onvoldoende gekend. Vismigraties van en naar het Schelde-estuarium en de structuur van deze populaties zullen worden bepaald met stabiele isotopen en genetische merkers, en gemodelleerd met dynamische modellen.","DateLastModified":{"date":"2025-07-02 08:33:20.809226","timezone_type":1,"timezone":"+02:00"},"ParentProID":null,"BeginYear":2002,"EndYear":2006,"BMonth":10,"EMonth":9,"BeginMonth":"October","EndMonth":"September","OrigTitleLangCode":"nl","OrigTitleLangID":41,"OrigTitleLangNL":"Nederlands","OrigTitleLang":"Dutch","OtherAbstractLangCode":"nl","OtherAbstractLangID":41,"OtherAbstractLang":"Dutch","OtherAbstractLangNL":"Nederlands","Progress":"Completed","ProgressNL":"Afgelopen","PublicFlag":1,"CheckedFlag":0,"ND":"2003-11-26","UD":"2007-11-12","DMPFlag":0,"Budget":250000,"BudgetCurrency":"EUR"},"parent":null,"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":null,"ProPartID":1588,"PublicFlag":1,"OrigNameLangCode":"en","OrigNameLangID":15,"FullOrigName":"Katholieke Universiteit Leuven; Department of Biology; Systematics and Ecology of Animals Section; Laboratory of Animal Diversity and Systematics","Line1":null,"Line2":null,"Line3":null,"Line4":null,"InsID":8835,"FullStandardName":"Katholieke Universiteit Leuven; Departement Biologie; Afdeling Dierenecologie en -systematiek; Diversiteit en Systematiek van Dieren","Role":null,"RoleID":null,"EncAddress":""},"parent":null,"institutes":null,"references":null,"conferences":null,"datasets":null,"persons":[{"Surname":"Guelinckx","Firstname":"Jef","Initials":"J.","LeaderFlag":0,"PersID":5751,"Role":null,"RoleID":null,"PastInstitute":null,"BeginDay":null,"BeginMonth":null,"BeginYear":null,"EndDay":null,"EndMonth":null,"EndYear":null},{"Surname":"Maes","Firstname":"Joachim","Initials":"J.","LeaderFlag":0,"PersID":213,"Role":"Co-promotor","RoleID":15,"PastInstitute":null,"BeginDay":null,"BeginMonth":null,"BeginYear":null,"EndDay":null,"EndMonth":null,"EndYear":null},{"Surname":"Volckaert","Firstname":"Filip","Initials":"F.A.M.","LeaderFlag":0,"PersID":13,"Role":"Promotor","RoleID":8,"PastInstitute":null,"BeginDay":null,"BeginMonth":null,"BeginYear":null,"EndDay":null,"EndMonth":null,"EndYear":null}],"pastpers":null,"subpers":null,"projects":null,"urls":null,"pictures":null,"published":null,"affrefs":null,"collections":null,"thesterms":null,"taxterms":null,"geoterms":null,"thestermsFRIS":null,"nXtins":null,"previns":null,"spcols":null,"resmessage":"no id specified","complete":0,"participantrec":null,"peerrevs":null,"urlmaps":null},{"instituterec":{"Acronym":"KULeuven","ProPartID":4958,"PublicFlag":1,"OrigNameLangCode":null,"OrigNameLangID":null,"FullOrigName":"University of Leuven","Line1":"Oude Markt 13","Line2":"3000 Leuven","Line3":null,"Line4":null,"InsID":2957,"FullStandardName":"KU Leuven","Role":"Sponsor","RoleID":3,"EncAddress":"Oude Markt 13, 3000 Leuven, Belgium"},"parent":null,"institutes":null,"references":null,"conferences":null,"datasets":null,"persons":[],"pastpers":null,"subpers":null,"projects":null,"urls":null,"pictures":null,"published":null,"affrefs":null,"collections":null,"thesterms":null,"taxterms":null,"geoterms":null,"thestermsFRIS":null,"nXtins":null,"previns":null,"spcols":null,"resmessage":"no id specified","complete":0,"participantrec":null,"peerrevs":null,"urlmaps":null}],"refs":null,"urls":null,"thesterms":[{"ThesaurusTerm":"ANE, Netherlands, Westerschelde","ThestID":182103,"ThesTypID":34,"ThesType":"ASFA Geoterms","OrigThesTerm":"ANE, Netherlands, Westerschelde","DutchTerm":null,"Code":null},{"ThesaurusTerm":"Ecosystems","ThestID":2638,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Ecosystems","DutchTerm":"Ecosystemen","Code":"c_2482"},{"ThesaurusTerm":"Life cycle","ThestID":4696,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Life cycle","DutchTerm":"Levenscyclus","Code":"c_4317"},{"ThesaurusTerm":"Population dynamics","ThestID":9702,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Population dynamics","DutchTerm":"Populatiedynamiek","Code":"c_6111"}],"taxterms":null,"geoterms":[{"GeoTerm":"Westerschelde","GeoObjectID":4752,"OrigGeoTerm":"Westerschelde","DutchTerm":"Westerschelde"}],"funderids":[{"FunderID":"3E020004","ThestID":181476,"FunderType":"Other contract id"}],"othtermsFRIS":null,"pictures":[],"spcols":[{"SpColID":269,"SpName":"ENCORA"},{"SpColID":165,"SpName":"ENCORA: BENCORE"},{"SpColID":49,"SpName":"Fishery"},{"SpColID":38,"SpName":"Marine Biodiversity and Ecosystem Functioning"},{"SpColID":27,"SpName":"ScheldeMonitor"}],"resmessage":"","complete":1}
