The ciliate is unable to sustain growth with this alga as the only food source, irrespective of concentration. Ciliate survival decreases at very high concentrations of <i>G. aureolum</i> probably due to toxic substances exuded from <i>G. aureolum</i> to the medium. This assumption is supported by the fact that growth of the ciliate is not affected by even very high concentrations of a non-toxic dinoflagellate, Heterocapsa triquetra. However, direct attempts to demonstrate toxic effects of exudates, using filtrates of dense cultures of <i>G. aureolum</i>, failed. Growth and grazing experiments were also carried out in which the ciliate was fed mixtures of <i>G. aureolum</i> and <i>H. triquetra</i> at relatively low algal concentrations. The growth of the ciliate was unaffected until <i>G. aureolum</i> accounted for about 70% of the total biomass. In cases where <i>G. aureolum</i> accounted for about 90% of the algal biomass, the growth rate of the ciliate was reduced by less than 25%. Grazing experiments demonstrated that <i>F. ehrenbergii</i> cannot selectively avoid ingestion of <i>G. aureolum</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Growth and grazing response of a ciliate feeding on the red tide dinoflagellate <i>Gyrodinium aureolum</i> in monoculture and mixture with a non-toxic alga","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":1995,"MonPub":null,"DateUpdate":"2009-04-10","DateCreate":"2009-04-10","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":133632,"PubliDate":1995,"Pagination":"65-72","XtraPublOfAnaID":null,"ISBN":null,"Volume":"121","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43354,"SerRR":"Marine Ecology Progress Series.
