Concurrently, phytoplankton growth must deal with resource acquisition. Experiments on mono- and mixed cultures of morphologically different diatoms exposed to copepods were performed to assess if size and shape were primary drivers in avoiding predation. Additionally, frustule silicification was investigated as a potential factor affecting prey selection by copepods. <i>Thalassiosira pseudonana</i>, <i>Conticribra weissflogii</i>, <i>Cylindrotheca closterium</i>, and <i>Phaeodactylum tricornutum</i> were exposed to the presence of <i>Temora longicornis</i>, a calanoid copepod. The physiological response in terms of growth, elemental composition and morphology was determined. The power of Image Flow Cytometry allowed functional single-cell analyses of mixed cultures in the presence and absence of copepods. Results highlighted that <i>T. pseudonana</i> although the most eaten by copepods in monospecific cultures, was not the preferred prey when the bigger <i>C. weissflogii</i> was added to the culture. When pennates were co-cultured with centric diatoms, their growth was unaffected by predators. Our data suggested that the frustule morphology contributes to long-term prey-predator interaction since the elongated thinner frustule, which evolved more recently, benefited cells in escaping from predators also when facing competition for resources.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Diatoms versus copepods: could frustule traits have a role in avoiding predation?","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-11 01:32:51.994637","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2022-08-31","DateCreate":"2022-03-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000759864700001","VABBcode":null,"OpenAcc":1,"DOI":"10.3389/fmars.2021.804960"},"refs":null,"anarec":{"AnaID":350145,"PubliDate":2022,"Pagination":"804960","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":233602,"SerRR":"Frontiers in Marine Science.
