{"projectrec":{"ProID":2288,"StandardTitle":"The impact of estuaries upon the goby Pomatoschistus minitus","OrigTitle":"Ecologisch belang van estuaria voor de mariene grondel Pomatoschistus minitus","Acronym":null,"AbstractEnglish":"This research aims to clarify the spatial and functional role of estuaries for juvenile marine fish. The question is raised which proportion of estuarine migrants contributes to the next cohort, compaired with their conspecific marine residents. Hereto fish have to be assigned to their respective habitats and exchange rates have to be determined. The Scheldt estuary-Southern Bight of the North Sea gradient is used as a model system and the targe fish species is the marine demersal sand goby (Pomatoschistus minutus; Gobiidae). Geochemical trace elements in otoliths (Sr/Ca will be used for the identification and the reconstruction of the individual life history (coupled with aging) of estuarine and marine residents in a spawning population of sand gobies. Quantification of the migrations dynamics between the marine spawning and the estuarine nursey grounds will be assessed using population dynamics and stable isotopes of fish tissues.","AbstractOtherLang":"Vele mariene vissoorten trekken in hun juveniele fase estuaria in. Estuaria worden daarom als kinderkamergebieden voor deze soorten beschouwd. Dit onderzoek richt zich op het kwantificeren van het belang van dit kinderkamerconcept. Hiervoor dienen vissen aan hun habitat toegekend te worden en dienen uitwisselingen tussen habitatten gekwantificeerd te worden. Het zuidelijk deel van de Noordzee en het Schelde-estuarium vormen hierbij ons studiegebied en de mariene grondelsoort, 'Pomatoschistus minutus' is de soort onder studie. Geochemische spoorelementen in otolieten (Sr/Ca) worden gebruikt om estuariene migranten van mariene residenten te onderscheiden in paaiende populaties. Hun individuele levensgeschiedenis zal hierbij gereconstrueerd worden Populatiedynamica en stabiele isotopenanalyse van de organen zal aangewend worden om de migraties tussen de paaigebieden en de estuariene gebieden te kwantificeren.","DateLastModified":{"date":"2025-07-02 08:33:20.809226","timezone_type":1,"timezone":"+02:00"},"ParentProID":null,"BeginYear":2002,"EndYear":2002,"BMonth":10,"EMonth":12,"BeginMonth":"October","EndMonth":"December","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":"2007-10-25","UD":"2009-02-24","DMPFlag":0,"Budget":null,"BudgetCurrency":"EUR"},"parent":null,"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":null,"ProPartID":8748,"PublicFlag":1,"OrigNameLangCode":"en","OrigNameLangID":15,"FullOrigName":"Katholieke Universiteit Leuven; Department of Biology; Systematics and Ecology of Animals Section; Laboratory of Aquatic Ecology and Evolutionary Biology","Line1":"Charles Deberiotstraat 32 bus 2439","Line2":"3000 Leuven","Line3":null,"Line4":null,"InsID":8836,"FullStandardName":"Katholieke Universiteit Leuven; Departement Biologie; Afdeling Dierenecologie en -systematiek; Aquatische Ecologie en Evolutiebiologie","Role":"Co-ordinator","RoleID":7,"EncAddress":"Charles Deberiotstraat 32 bus 2439, 3000 Leuven, Belgium"},"parent":null,"institutes":null,"references":null,"conferences":null,"datasets":null,"persons":[{"Surname":"Ollevier","Firstname":"Frans","Initials":"F.","LeaderFlag":0,"PersID":34,"Role":"Promotor","RoleID":8,"PastInstitute":0,"BeginDay":null,"BeginMonth":null,"BeginYear":null,"EndDay":null,"EndMonth":null,"EndYear":null},{"Surname":"Guelinckx","Firstname":"Jef","Initials":"J.","LeaderFlag":0,"PersID":5751,"Role":"Co-promotor","RoleID":15,"PastInstitute":1,"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}],"refs":null,"urls":null,"thesterms":[{"ThesaurusTerm":"ANE, North Sea","ThestID":182108,"ThesTypID":34,"ThesType":"ASFA Geoterms","OrigThesTerm":"ANE, North Sea","DutchTerm":null,"Code":null},{"ThesaurusTerm":"Estuaries","ThestID":2895,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Estuaries","DutchTerm":"Estuaria","Code":"c_2673"},{"ThesaurusTerm":"Habitats","ThestID":89366,"ThesTypID":2,"ThesType":"CSA Technology Research Database Master Thesaurus","OrigThesTerm":"Habitats","DutchTerm":"Habitats","Code":null},{"ThesaurusTerm":"Habitats","ThestID":118583,"ThesTypID":4,"ThesType":"CAB Thesaurus","OrigThesTerm":"Habitats","DutchTerm":"Habitats","Code":"54043"}],"taxterms":[{"TaxTerm":"Pomatoschistus minutus (Pallas, 1770) [Sand goby]","AphiaID":126928,"OrigTaxTerm":"Pomatoschistus minutus (Pallas, 1770)","DutchTerm":"Dikkopje"}],"geoterms":[{"GeoTerm":"North Sea","GeoObjectID":2350,"OrigGeoTerm":"North Sea","DutchTerm":"Noordzee"}],"funderids":null,"othtermsFRIS":[{"OtherTerm":"Scheldt estuary","DutchTerm":null,"OthtID":8873}],"pictures":[],"spcols":[{"SpColID":27,"SpName":"ScheldeMonitor"}],"resmessage":"","complete":1}
