{"projectrec":{"ProID":4618,"StandardTitle":"Modelling benthos-mediated biogeochemical cycling in estuarine environments","OrigTitle":null,"Acronym":null,"AbstractEnglish":"Macrobenthos plays a fundamental role in estuarine ecosystem dynamics. It is not only important food resource in benthic and pelagic food chains, but also good indicator of biotic integrity which is able to reflect the ongoing changes in the estuarine ecosystem. The study site, which measures 160km from the mouth near Vlissingen (The Netherlands) to Gent (Belgium) , Schelde estuary, has been put forward as an area that is under permanent stress due to a high load of urban, industrial and agricultural waste. So this study aims to develop better predictions of future changes to the estuarine system, which is a prerequisite for improving conservation and management strategies.\nA combined field, mesocosm and modeling approach will be applied to quantify the linkages between biogeochemical and suspension matter cycling, and macrobenthos functional role. A non-linear quantile regression model will be proposed for predicting spatio-temporal patterns of macrobenthic species, by the extended use of spline transformations in the multi-quantile regression. The functional importance of macrobenthos for biogeochemical cycling will further be explored by quantifying the faunal contribution to the exchange of nutrients and oxygen between the sediment and the water column. Statistical models will be developed from the measured data of bioturbation and bio-irrigation in the laboratory, together with the environmental variables. Ultimately the enhanced species distribution model and the calibrated biogeochemical model will be coupled. Integration of these models will allow the prediction of organic matter cycling, suspended matter and nutrient dynamics under future scenarios of hydro-morphological change.","AbstractOtherLang":"Het macrobenthos spelt een belangrijke rol in het functioneren van mariene kustsystemen zoals estuaria. Door bioturbatie, bio-irrigatie en biodepositie bepaalt deze groep van organismen bijvoorbeeld mede de benthisch-pelagische koppeling. In dit onderzoeksproject willen we deze link tussen biogeochemie en benthos diversiteit en functionaliteit bepalen en voorspellen op de schaal van het Schelde estuarium en het aangrenzende mariene mondingsgebied. Daartoe willen we drie types van modellen ontwikkelen (een benthosdistributie model, een biogeochemisch model en een hydrodynamische model) en koppelen om de impact van verschillende hydrodynamische scenario’s (dredging, zeespiegelstijging, …) op de biogeochemie te voorspellen aan de hand van veranderingen in de bodemdiergemeenschap.","DateLastModified":{"date":"2024-05-06 10:25:46.257000","timezone_type":1,"timezone":"+00:00"},"ParentProID":null,"BeginYear":2015,"EndYear":null,"BMonth":10,"EMonth":null,"BeginMonth":"October","EndMonth":null,"OrigTitleLangCode":null,"OrigTitleLangID":null,"OrigTitleLangNL":null,"OrigTitleLang":null,"OtherAbstractLangCode":"nl","OtherAbstractLangID":41,"OtherAbstractLang":"Dutch","OtherAbstractLangNL":"Nederlands","Progress":null,"ProgressNL":null,"PublicFlag":1,"CheckedFlag":0,"ND":"2016-04-06","UD":"2016-04-22","DMPFlag":0,"Budget":null,"BudgetCurrency":"EUR"},"parent":null,"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":"MARBIOL","ProPartID":15865,"PublicFlag":1,"OrigNameLangCode":"en","OrigNameLangID":15,"FullOrigName":"Ghent University; Faculty of Sciences; Biology Department; Marine Biology Section","Line1":"Campus De Sterre, S8","Line2":"Krijgslaan 281","Line3":"9000 Gent","Line4":null,"InsID":13,"FullStandardName":"Universiteit Gent; Faculteit Wetenschappen; Vakgroep Biologie; Onderzoeksgroep Mariene Biologie","Role":null,"RoleID":null,"EncAddress":"Campus De Sterre, S8, Krijgslaan 281, 9000 Gent, Belgium"},"parent":null,"institutes":null,"references":null,"conferences":null,"datasets":null,"persons":[{"Surname":"Moens","Firstname":"Tom","Initials":"T.","LeaderFlag":0,"PersID":229,"Role":"Supervisor","RoleID":2,"PastInstitute":0,"BeginDay":null,"BeginMonth":null,"BeginYear":null,"EndDay":null,"EndMonth":null,"EndYear":null},{"Surname":"Van Colen","Firstname":"Carl","Initials":"C.","LeaderFlag":0,"PersID":10023,"Role":"Supervisor","RoleID":2,"PastInstitute":0,"BeginDay":null,"BeginMonth":null,"BeginYear":null,"EndDay":null,"EndMonth":null,"EndYear":null},{"Surname":"Fang","Firstname":"Xiaoyu","Initials":"X.","LeaderFlag":0,"PersID":32559,"Role":null,"RoleID":null,"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},{"instituterec":{"Acronym":null,"ProPartID":15880,"PublicFlag":1,"OrigNameLangCode":null,"OrigNameLangID":null,"FullOrigName":null,"Line1":"Drake Circus","Line2":"Plymouth PL4 8AA","Line3":null,"Line4":null,"InsID":6628,"FullStandardName":"University of Plymouth; School of Marine Science and Engineering","Role":null,"RoleID":null,"EncAddress":"Drake Circus, Plymouth PL4 8AA, UK"},"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":"Bioturbation","ThestID":1028,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Bioturbation","DutchTerm":"Bioturbatie","Code":"c_a3354940"}],"taxterms":null,"geoterms":null,"funderids":null,"othtermsFRIS":[{"OtherTerm":"Benthic-pelagic Fluxes","DutchTerm":null,"OthtID":19291},{"OtherTerm":"Biogeochemical modelling","DutchTerm":null,"OthtID":7628},{"OtherTerm":"Bio-irrigation","DutchTerm":null,"OthtID":16176},{"OtherTerm":"Species Distribution Model","DutchTerm":null,"OthtID":19290}],"pictures":[],"spcols":null,"resmessage":"","complete":1}
