Diatom species were selected in view of their different size and shape: <i>Navicula phyllepta</i> (small and elliptic, single cells), <i>Grammatophora marina</i> (large cells, colonies), <i>Cylindrotheca closterium</i> (small but more elongated, single cells). Diatoms were offered in different combinations within three levels of food diversity. In each combination, one diatom species was enriched in the stable l3<sup>C</sup> isotope to facilitate tracing of food resources in the harpacticoids. We tested whether uptake of a particular diatom is affected by food diversity and this was true for all diatom species and copepod species: uptake of the labeled diatom decreased when alternative food resources (other diatoms) were available. Further, there were clear species-specific responses to diatom identity. Irrespective of level of food diversity, <i>H. obscurus</i> took up high amounts of<i> marina</i> whereas both <i>P. fulvofasciata</i> and <i>T. brevicornis</i> preferred <i>C. closterium</i> when given the choice between different diatoms. Diatom selection by harpacticoid copepods thus seems to be affected both by food diversity and food identity.","AbstractOtherLang":null,"BibLvlCode":"M","StandardTitle":"Effect of food diversity on diatom selection by harpacticoid copepods","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":2005,"DateUpdate":"2012-01-06","DateCreate":"2006-01-10","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":78646,"ISBN":null,"PubliDate":2005,"IssueDate":null,"Volume":null,"Issue":null,"Pagination":"21","Place":"Gent","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":null,"SerRR":null,"Ser2BRefID":null,"Ser2RR":null,"StandardTitleSer":null,"ISSN":null,"AbbrevSer":null,"Degree":"MSc","ThesisID":78646,"InsID":2048,"Acronym":"MARELAC","FullStandardName":"Universiteit Gent; Faculteit Wetenschappen; Vakgroep Biologie; Msc.
