They are introduced in marine ecosystems through primary producers and when grazed upon, they are consumed, incorporated or modified by first-level consumers. As the availability of EFA in the ecosystem is affected by ambient temperature, the predicted rise in ocean temperature might alter the availability of these EFA at the basis of marine food webs. Despite the FA bioconversion capacity of certain benthic copepod species, their lipid (FA) response to varying temperatures is understudied. Therefore, the temperate, intertidal copepod <em>Platychelipus littoralis</em> was offered a mono and mixed diatom diet at 4, 15 °C (normal range) and at 24 °C (elevated temperature) to investigate the combined effects of temperature and resource availability on its FA content and composition. <em>P. littoralis</em> showed a flexible thermal acclimation response. Cold exposure increased the degree of FA unsaturation and the EPA%, and induced a shift towards shorter chain FA in the copepod’s membranes. Furthermore, a mixed diet reduced the impact of heat stress on the copepod’s membrane FA composition. Temperature affected the trophic transfer of EPA and DHA differently. While dietary resources could fully compensate for the temperature effects on total lipid and EPA content in the copepods, no such counterweigh was observed for the DHA dynamics. Heat stress lowered the DHA concentration in copepods regardless of the resources available and this implies negative effects for higher trophic levels.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Temperature-induced changes in fatty acid dynamics of the intertidal grazer <i>Platychelipus littoralis</i> (Crustacea, Copepoda, Harpacticoida): insights from a short-term feeding experiment","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:31:55.803413","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Biochemical ecology; Storage lipids; Thermal acclimation; Diatom","OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2016-03-10","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000374359800006","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.jtherbio.2016.02.002"},"refs":null,"anarec":{"AnaID":253785,"PubliDate":2016,"Pagination":"44-53","XtraPublOfAnaID":null,"ISBN":null,"Volume":"57","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43292,"SerRR":"Journal of Thermal Biology.
