We found a dichotomy between a depleted d13C cluster and an enriched d13C cluster. Epibionts from oceanic/pelagic or neritic/benthic habitats were largely consistent with this dichotomy. The bimodal distribution of d13C could reflect a bimodal foraging strategy or—because of the potential for confounding among four gradients of d13C in marine environments—a polymodal foraging strategy. We integrate our results with results from other stable isotope studies, satellite telemetry, and flipper tags to evaluate potential foraging strategies. Understanding foraging strategies is essential for development of management plans for this endangered species that has suffered a 43% population decline over the last decade.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Polymodal foraging in adult female loggerheads (<i>Caretta caretta</i>)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:32:51.065978","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2010,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2016-05-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000272801100011","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00227-009-1300-4"},"refs":null,"anarec":{"AnaID":256240,"PubliDate":2010,"Pagination":"113-121","XtraPublOfAnaID":null,"ISBN":null,"Volume":"157","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
