The d<sup>13</sup>C values of all AAs decreased with latitude, were positively correlated with bulk d<sup>13</sup>C data, and, therefore, tracked the isotopic baseline. However, we were not able to discern additional ecological information from these d<sup>13</sup>C values. In contrast, the d<sup>15</sup>N values of AAs distinguished the isotopic value of the nitrogen at the base of the food web from the trophic level of the consumer, providing new insight for the study of the trophic ecology of seabirds. The difference in the bulk d<sup>15</sup>N values of northern and southern rockhopper penguins <i>Eudyptes chrysocome</i> ssp. was due to both a difference in their foraging location (different d<sup>15</sup>N <sub>phe</sub>) and their trophic levels (different ?d<sup>15</sup>N<sub>glu-phe</sub>). The d<sup>15</sup>N<sub> phe</sub> values of king <i>Aptenodytes patagonicus</i> and Adélie penguins <i>Pygoscelis adeliae</i> were higher than those of rockhoppers, which could reflect a foraging on mesopelagic prey for king penguins and, in the highly productive Antarctic shelf waters, for Adelie penguins. The ?d<sup>15</sup>N<sub>glu-phe</sub> accurately reflected the relative trophic level of penguins, but further work is required to determine the trophic enrichment factors for compound-specific isotope analysis.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Nitrogen and carbon isotope values of individual amino acids: a tool to study foraging ecology of penguins in the Southern Ocean","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"delta(15)N; delta(13)C; Compound specific; Isotopic niche; Trophic level","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2012-01-25","DateCreate":"2011-12-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000271218100025","VABBcode":null,"OpenAcc":0,"DOI":"10.3354/meps08215"},"refs":null,"anarec":{"AnaID":211279,"PubliDate":2009,"Pagination":"293-306","XtraPublOfAnaID":null,"ISBN":null,"Volume":"391","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43354,"SerRR":"Marine Ecology Progress Series.
