However, the haptophyte had strong negative effects on copepod egestion and reproduction rates, both when the haptophyte was offered as the only food, and when offered in mixtures with <i>Rhodomonas baltica</i> Karsten sensu Zimmermann, an alga known to be ingested and support reproduction in <i>Acartia</i>. The rates were depressed already at concentrations of 0.1-0.3 x 10<sup>6</sup> cells l<sup>-1</sup> of <i>P. patelliferum</i>, and decreased further with increasing concentration of the haptophyte. At typical bloom concentrations (more or equal to 4 x 10<sup>6</sup> cells l<sup>-1</sup> ) of <i>P. patelliferum</i>, the rates were no greater than those of starved copepods. These results demonstrates that zooplankton feeding and reproduction in coastal waters may be constrained by presence of toxic haptophytes, also when these algae occur in moderate concentrations and mortality is not registered.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Repression of copepod feeding and fecundity by the toxic haptophyte <i>Prymnesium patelliferum</i>","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":1996,"MonPub":null,"DateUpdate":"2024-01-02","DateCreate":"2003-01-31","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":31825,"PubliDate":1996,"Pagination":"339-344","XtraPublOfAnaID":null,"ISBN":null,"Volume":"81","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43909,"SerRR":"Sarsia.
