After 1 month of exposure, the abundances of meiobenthic taxa and the taxonomic and morpho-functional diversity of nematodes showed significant differences between the <em>Spirulina</em> and <em>Spirulina</em>&nbsp;+&nbsp;chromium groups. The nematodes were more tolerant of all types of stressors compared to harpacticoids, polychaetes, and oligochaetes, and the lowest taxonomic and morpho-functional diversity of nematodes was observed in the highest sedimentary concentration of <em>S.&nbsp;platensis</em> (50% DW). The mixed treatments may have been richer in micro-habitats and subject to low selective pressure, thereby hosting nematodes with a wide range of adaptations. The responses of the nematode species differed depending on their functional traits. <em>Spirulina</em> enriched with chromium induced two responses for the same feeding group: high toxicity for <em>Daptonema fallax</em> and low toxicity for two <em>Theristus</em> species (<em>T.&nbsp;flevensis</em> and <em>T.&nbsp;modicus</em>). The ecotoxicity of the <em>Spirulina</em>/chromium mixtures were lower than that of <em>Spirulina</em> alone, suggesting mutual neutralization between these two elements. The association between functional traits and taxonomic diversity showed that the effects of the mixtures were not additive and that one of the stressors camouflaged the effect of the other. Our findings should encourage the commercialization of chromium-enriched <em>S.&nbsp;platensis</em> owing to its lower ecotoxicity than <em>Spirulina</em> alone.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Toxicity of a chromium-enriched superfood, <i>Spirulina platensis</i>, assessed by taxonomic and morpho-functional diversity of marine meiofauna","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-02 01:32:02.663022","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Meiobenthic nematodes; Taxonomic diversity; Morpho-functional diversity","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2020-06-04","DateCreate":"2020-06-04","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000533524300035","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.envpol.2020.114350"},"refs":null,"anarec":{"AnaID":324789,"PubliDate":2020,"Pagination":"114350","XtraPublOfAnaID":null,"ISBN":null,"Volume":"262","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42834,"SerRR":"Environmental Pollution.
