All species are known to be necrophagous; however, this study revealed through combination of gut-content analysis with the morphological characteristics of their mandibles and available information on feeding ecology, the complexity of their trophic strategies. Only mature individuals of <i>A. nugax</i> are true scavengers; immature individuals of this species feed on both animal and non-animal food. <i>A. sarsi</i> and <i>O. caricus</i> are scavengers and predators; the former prefers polychaetes, while the latter relies mostly on zooplankton. <i>O. edwardsii</i> is an omnivorous feeder, and the set of its primary food consists of carrion, crustaceans, and algae. <i>O. minuta</i> is a detrivorous&#8211;carnivorous species. These results indicate that niche overlap among these closely related species is reduced, not only by spatial segregation, but also by the exploitation of different components of food resources.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Food resource partitioning among Arctic sublittoral lysianassoid amphipods in summer","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"lysianassoidea; feeding ecology; Arctic","OtherDescriptors":null,"Notes":null,"AnaPub":2008,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2008-05-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000255059200002","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00300-008-0404-5"},"refs":null,"anarec":{"AnaID":122092,"PubliDate":2008,"Pagination":"663-670","XtraPublOfAnaID":null,"ISBN":null,"Volume":"31","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43637,"SerRR":"Polar Biology.
