Clearance rates for <em>M. leidyi</em> incubated with phytoplankton were generally negative, but ranged up to 4.5 1 ctenophore<sup>-1</sup> day<sup>-1</sup> when the large (80 µm ø) diatom <em>Ditylum brightwelli</em> was offered as a food source. These highest ingestion rates would provide <em>Mnemiopsis</em> with only 21 % of its daily carbon requirements for respiration. Mean shrinkage of <em>M. leidyi</em> was 8.2–51% when incubated with phytoplankton. Although <em>M. leidyi</em> neither fed actively on phytoplankton, nor satisfied its nutritional needs on such a diet, the chain-forming diatom <em>Skeletonema costatum</em> became entangled in mucus strands and balls produced by <em>M. leidyi</em> in the absence of zooplankton. Attachment onto mucus occurred at phytoplankton concentrations commonly observed in Narragansett Bay and may be important in the formation of “marine snow” during summer <em>M. leidyi</em> pulses; phytoplankton sinking rate and the “package size” available to herbivores would also be affected. The experiments support our previous hypothesis based on field observations in Narragansett Bay that <em>M. leidyi</em> indirectly regulates phytoplankton abundance there during the summer bloom as a consequence of predation on zooplankton. The extent to which <em>M. leidyi</em> influenced phytoplankton dynamics in the microcosms was dependent on the relative abundance and physiological state of the three trophic levels. A food web diagram for <em>M. leidyi</em> is presented.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Experimental evaluation of herbivory in the ctenophore <i>Mnemiopsis leidyi</i> relevant to ctenophore-zooplankton-phytoplankton interactions in Narragansett Bay, Rhode Island, USA","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:32:41.221345","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1982,"MonPub":null,"DateUpdate":"2015-01-28","DateCreate":"2015-01-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1982NX42700003","VABBcode":null,"OpenAcc":0,"DOI":"10.1093/plankt/4.2.219"},"refs":null,"anarec":{"AnaID":244307,"PubliDate":1982,"Pagination":"219-236","XtraPublOfAnaID":null,"ISBN":null,"Volume":"4","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43255,"SerRR":"Journal of Plankton Research.
