Due to its invasive success and its rapid range expansion, there has been much interest in the feeding behavior and the trophic position of <i>M. leidyi<\/i>. This study aimed to determine some of the basic interactions of <i>M. leidyi<\/i> with the native pelagic zooplankton in the Belgian part of the North Sea and the Westerscheldt estuary by means of biochemical biomarkers, such as stable isotopes and fatty acids , in combination with grazing experiments and 13C tracer experiments. Our findings showed that <i>M. leidyi<\/i> is a very efficient predator with very short digestion times that can found in many different environmental conditions and ecosystems. Furthermore, our results emphasized the importance of spatial and temporal variations in the isotopic signature of various taxa when interpreting trophic interactions. This study supported the position of <i>M. leidyi<\/i> as a secondary consumer. Furthermore, our findings suggest that the native ctenophore Pleurobrachia pileus uses a different ecological niche than <i>M. leidyi<\/i> and could be positioned at a higher trophic level. This supports the hypothesis that M. leidyi and <i>P. pileus<\/i> are feeding on different food sources and implies that two ctenophores can co-occur rather than outcompete each other. Finally, this study shows that 13C tracer experiments can be a very helpful tool when identifying potential prey species and has many possible application for future research involving gelatinous zooplankton.","AbstractOtherLang":null,"BibLvlCode":"M","StandardTitle":"Trophic position of the invasive ctenophore <i>Mnemiopsis leidyi<\/i>: an experimental approach","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":2013,"DateUpdate":"2017-02-08","DateCreate":"2014-01-22","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":232882,"ISBN":null,"PubliDate":2013,"IssueDate":null,"Volume":null,"Issue":null,"Pagination":"33 + annexes","Place":"Brussel","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":null,"SerRR":null,"Ser2BRefID":null,"Ser2RR":null,"StandardTitleSer":null,"ISSN":null,"AbbrevSer":null,"Degree":"MSc","ThesisID":232882,"InsID":null,"Acronym":null,"FullStandardName":null,"ToPubliDate":null,"SerNotes":null,"eISBN":null,"Pages":33},"serrec":null,"relations":null,"relationsRev":null,"addrec":null,"othpubs":null,"ownerships":null,"authors":[{"AutName":"Vanhove","Firstname":"Brecht","Initials":"B.","Affiliation":"Oceans & Lakes, Interuniversity Master in Marine and Lacustrine Science and Management","Discriminator":null,"CorporateFlag":0,"BEntID":224593,"AutID":174197,"OrderNr":1,"DegrID":null,"EditorFlag":0,"CorrespFlag":0,"IllustratorFlag":0,"ReviserFlag":0,"TranslatorFlag":0,"InsAcronym":null,"InsFSN":"Oceans & Lakes : Master of Marine and Lacustrine Science and Management","ORCID":null,"PersID":32934,"InsID":11152}],"mapdetails":null,"datasets":null,"monographs":null,"monparts":null,"serparts":null,"BEntOpen":null,"BEntPrivate":null,"availability":[{"BInstID":253983,"LibID":36,"BRefID":232882,"EmbargoDate":null,"FullEmbargoDate":null,"PhysMedID":16,"hasOCRd":1,"ShelfLocCode":"253983","RFID":null,"PaidValue":null,"Medium":"Server","Description":"Interne VLIZ documenten","Acronym":"VLIZ","Library":"Vlaams Instituut voor de Zee","DutchTerm":"Non-open access","URL":null,"ClassifID":228,"Classification":"Non-open access","ReqLink":1,"ClassifTypID":3,"URLLocation":"https:\/\/www.vliz.be\/imisdocs\/publications\/","SubDir":1,"InternalReq":1,"LoggedInReq":1,"Disclaimer":"Disclaimer_VLIZ_Intern","DutchDisclaimer":"<p>Deze publicatie is enkel beschikbaar voor persoonlijk gebruik binnen de Innovocean site <br \/>en mag op geen enkele manier verder worden verspreid.<\/p>","FileFormat":".pdf","FileDescr":"pdf","InsPub":1,"InsID":36,"FileFormID":6,"LendableFlag":1,"PublicFlag":1,"orderLib":"A","Notes":null,"AccConID":null,"AccessConstraint":null,"LicURL":null}],"litstyles":[{"LitStyID":7,"Style":"Dissertation"}],"thespers":[{"PersID":223,"Surname":"De Troch","Firstname":"Marleen","Initials":"M.","Role":"Promotor"},{"PersID":226,"Surname":"Hostens","Firstname":"Kristian (Kris)","Initials":"K.","Role":"Co-promotor"},{"PersID":19,"Surname":"Vincx","Firstname":"Magda","Initials":"M.","Role":"Co-promotor"},{"PersID":23823,"Surname":"Vansteenbrugge","Firstname":"Lies","Initials":"L.","Role":"Co-ordinator"}],"arch2discl":null,"SERpubls":null,"MONpubls":null,"pictures":[],"thestermsPath":null,"thestermsASFA":null,"taxtermsASFA":null,"geotermsASFA":null,"collections":[{"Collection":"ScheldeMonitor","ShortName":"scheldemonitor"},{"Collection":"VLIZ Acknowledged Publications","ShortName":"VLIZ ackn"}],"conf":null,"proj":null,"Physdatasets":null,"spcols":{"5":{"SpName":"Belgian theses on marine topics","SpColID":5,"ParSpColID":396,"TopParID":396,"ShortName":"Belgian marine theses","URLLocation":null,"LibID":null,"OpenRepoFlag":0,"SpTypID":null,"TopParIDNotWebsite":396,"SpColPath":"vliz:biblio\/Belgian marine theses"},"222":{"SpName":"BMB -
