Mixoplankton, able to photosynthesize and feed simultaneously in the one cell, can compensate shortage of nutrients by phagotrophy, theoretically upgrading their nutritional quality for their predators: the zooplankton. Yet, the additional value that phagotrophy in mixoplankton may provide to support zooplankton growth and recruitment has been poorly explored. Therefore, we investigated the feeding and reproductive performances of the copepods <i>Paracartia grani</i> and <i>Centropages typicus</i> on mono-diets of the dinoflagellate <i>Karlodinium veneficum</i> grown as strict autotroph and as mixotroph, both under N and P depletion, and in nutrient-balanced conditions (f/2 medium; only as autotroph). Feeding and reproduction outputs were generally higher in <i>P. grani</i> than in <i>C. typicus</i>. Both copepod species ingested the mixotrophic <i>K. veneficum</i> at similar rates than the autotrophic ones in either nutrient-limited scenario. However, egg production and recruitment rates generally increased when feeding on mixotrophs, in <i>P. grani</i> on both N- and P-limited diets, and in <i>C. typicus</i> under P limitation. In general, P limitation influenced copepod physiology more than N depletion. Our results show that phagotrophy upgrades nutritional quality in nutrient-limited mixotrophs as prey for copepods compared to the strict autotrophic ones. These findings are among the first reported cases of copepod ingestion in the laboratory on actively feeding mixoplankton, and they highlight the importance of considering the trophic mode of the protist and the response by various zooplanktonic predators when attempting to understand the functioning of marine planktonic food webs.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Mixotrophy upgrades food quality for marine calanoid copepods","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-03 01:32:55.658158","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2022-06-29","DateCreate":"2022-06-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000710122700001","VABBcode":null,"OpenAcc":1,"DOI":"10.1002/lno.11948"},"refs":null,"anarec":{"AnaID":353103,"PubliDate":2021,"Pagination":"4125-4139","XtraPublOfAnaID":null,"ISBN":null,"Volume":"66","Issue":"12","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43511,"SerRR":"Limnology and Oceanography.
