Specifically, we aimed to identify the possible facilitation of diatom productivity by the use of organic exudates produced by other species in the community focusing on within-species variation in this response for <i>Cylindrotheca closterium</i>. Three different strains (VD 18, VDO5 and VDO6) collected from intertidal mudflat of \"Plaat van Doe1\", the Westerschelde estuary of <i>C. closterium</i> (Ehrenberg) were cultured in different treatments: F/2 nutrient, in the polyculture of other <i>Navicula</i> species and in spent medium. Yields of <i>Cylindrotheca</i> strains were significantly different from each other as well as for between treatments. Some strains of <i>C. closterium</i> showed significantly better growth in polycultures and in spent medium. Proportional deviation of strain VD 18' s yield from its expected value was 1.5, showing a positive interaction with other species and higher than the other strains. To test the bacterial activity that may influence degradation of organic compounds in spent medium, another experiment was performed under axenic and non axenic conditions. <i>C. closterium</i> aggregates were found in spent medium treatment when cells were grown under both conditions. As these cultures received half of F /2 nutrient or spent medium effect to the clustering, we tested F/2 nutrient concentration. Statistically, no significant differences of different F/2 nutrient concentration on <i>C. closterium</i> production were found. Lastly, there was significantly positive effect of galactose, mannan and spent medium on <i>C. closterium</i> production. Our combined results demonstrate that heterotrophy may contribute to facilitative interactions in benthic diatom communities and hence help explain positive diversity-productivity relationships in microphytobenthos. In addition, significant variation between strains was observed in their response, contributing to the growing realization of considerable variation in phenotypic traits among genotypes of microalgae.","AbstractOtherLang":null,"BibLvlCode":"M","StandardTitle":"Heterotrophic capabilities of estuarine and marine benthic diatoms","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":2006,"DateUpdate":"2014-02-03","DateCreate":"2006-10-02","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":102593,"ISBN":null,"PubliDate":2006,"IssueDate":null,"Volume":null,"Issue":null,"Pagination":"41, 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":102593,"InsID":2015,"Acronym":"ECOMAMA","FullStandardName":"Vrije Universiteit Brussel; Faculteit Wetenschappen; Vakgroep Biologie; Ecological Marine Management Programme","ToPubliDate":null,"SerNotes":null,"eISBN":null,"Pages":41},"serrec":null,"relations":null,"relationsRev":null,"addrec":null,"othpubs":null,"ownerships":null,"authors":[{"AutName":"Kaewnuratchadasorn","Firstname":"Pattaratjit","Initials":"P.","Affiliation":null,"Discriminator":null,"CorporateFlag":0,"BEntID":99427,"AutID":65143,"OrderNr":1,"DegrID":null,"EditorFlag":0,"CorrespFlag":0,"IllustratorFlag":0,"ReviserFlag":0,"TranslatorFlag":0,"InsAcronym":null,"InsFSN":null,"ORCID":null,"PersID":null,"InsID":null}],"mapdetails":null,"datasets":null,"monographs":null,"monparts":null,"serparts":null,"BEntOpen":null,"BEntPrivate":null,"availability":[{"BInstID":230434,"LibID":36,"BRefID":102593,"EmbargoDate":null,"FullEmbargoDate":null,"PhysMedID":16,"hasOCRd":1,"ShelfLocCode":"230434","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":135,"Surname":"Vyverman","Firstname":"Wim","Initials":"W.","Role":"Promotor"},{"PersID":21,"Surname":"Sabbe","Firstname":"Koen","Initials":"K.","Role":"Co-promotor"},{"PersID":10717,"Surname":"Vanelslander","Firstname":"Bart","Initials":"B.","Role":"Promotor"}],"arch2discl":null,"SERpubls":null,"MONpubls":null,"pictures":[],"thestermsPath":null,"thestermsASFA":null,"taxtermsASFA":null,"geotermsASFA":[{"GeoTerm":"Plaat van Doel"}],"collections":[{"Collection":"ScheldeMonitor","ShortName":"scheldemonitor"}],"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 -
