Abstract
In the open ocean, eddies and associated structures (fronts, filaments) have strong influences on the foraging activities of top-predators through the enhancement and the distribution of marine productivity, zooplankton and fish communities. Investigating how central place foragers, such as penguins, find and use these physical structures is crucial to better understanding their at-sea distribution. In the present study, we compared the travel heading and speed of the world's most abundant penguin, the Macaroni penguin (Eudyptes chrysolophus), with the distribution of surface physical structures (large-scale fronts, eddies and filaments).

Six males at incubation stage were equipped with GPS loggers to get their trajectories. We used Eulerian and Lagrangian methods to locate large-scale fronts, mesoscale eddies (10-100 km) and part of the sub-mesoscale structures (<10 km, filaments) at the surface of the ocean. By comparing the positions of birds and these structures, we show that Macaroni penguins: i) target the sub Antarctic Front; ii) increase their foraging activity within a highly dynamic area, composed of eddy fields and filamentary structures; and iii) travel in the same direction as the predominant currents.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">We show that penguins adjust their travel speed and movement during their whole trips in relation with the oceanographic structures visited. At a large scale, we hypothesize that Macaroni penguins target the sub Antarctic Front to find profitable patches of their main prey. At finer scale, Macaroni penguin may adopt a horizontal drifting behavior in strong currents, which could be a way to minimize costs of displacement.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Bon</LastName><ForeName>Cecile</ForeName><Initials>C</Initials><AffiliationInfo><Affiliation>Centre d'Etudes Biologiques de Chizé, UMR 7372, CNRS - Université de La Rochelle, 79360 Villiers en Bois, France.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Della Penna</LastName><ForeName>Alice</ForeName><Initials>A</Initials><AffiliationInfo><Affiliation>Sorbonne Universités, UPMC Université Paris 06, UMR 7159, LOCEAN-IPSL, F-75005, Paris, France/Université Paris-Diderot/CSIRO-UTAS Quantitative Marine Science Program, IMAS, Private Bag 129, Hobart, TAS 7001 Australia.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>d'Ovidio</LastName><ForeName>Francesco</ForeName><Initials>F</Initials><AffiliationInfo><Affiliation>Sorbonne Universités, UPMC Université Paris 06, UMR 7159, LOCEAN-IPSL, F-75005 Paris, France.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Y P Arnould</LastName><ForeName>John</ForeName><Initials>J</Initials><AffiliationInfo><Affiliation>School of Life and Environmental Sciences, Faculty of Science, Engineering and the Built Environment, Deakin University, 221 Burwood Highway, Burwood, VIC 3125 Australia.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Poupart</LastName><ForeName>Timothée</ForeName><Initials>T</Initials><AffiliationInfo><Affiliation>Centre d'Etudes Biologiques de Chizé, UMR 7372, CNRS - Université de La Rochelle, 79360 Villiers en Bois, France.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Bost</LastName><ForeName>Charles-André</ForeName><Initials>CA</Initials><AffiliationInfo><Affiliation>Centre d'Etudes Biologiques de Chizé, UMR 7372, CNRS - Université de La Rochelle, 79360 Villiers en Bois, France.</Affiliation></AffiliationInfo></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType></PublicationTypeList><ArticleDate DateType="Electronic"><Year>2015</Year><Month>09</Month><Day>21</Day></ArticleDate></Article><MedlineJournalInfo><Country>England</Country><MedlineTA>Mov Ecol</MedlineTA><NlmUniqueID>101635009</NlmUniqueID><ISSNLinking>2051-3933</ISSNLinking></MedlineJournalInfo><CommentsCorrectionsList><CommentsCorrections RefType="Cites"><RefSource>Proc Natl Acad Sci U S A. 2009 May 19;106(20):8245-50</RefSource><PMID Version="1">19416811</PMID></CommentsCorrections><CommentsCorrections RefType="Cites"><RefSource>Proc Biol Sci. 2004 May 7;271 Suppl 4:S246-8</RefSource><PMID Version="1">15252997</PMID></CommentsCorrections><CommentsCorrections RefType="Cites"><RefSource>Proc Biol Sci. 2006 Nov 7;273(1602):2697-702</RefSource><PMID Version="1">17015330</PMID></CommentsCorrections><CommentsCorrections RefType="Cites"><RefSource>J Exp Biol. 1994 Sep;194(1):83-96</RefSource><PMID Version="1">9317385</PMID></CommentsCorrections><CommentsCorrections RefType="Cites"><RefSource>J Anim Ecol. 2007 Jul;76(4):826-36</RefSource><PMID Version="1">17584388</PMID></CommentsCorrections><CommentsCorrections RefType="Cites"><RefSource>Proc Biol Sci. 2001 Feb 22;268(1465):377-84</RefSource><PMID Version="1">11270434</PMID></CommentsCorrections><CommentsCorrections RefType="Cites"><RefSource>J R Soc Interface. 2012 Dec 7;9(77):3351-8</RefSource><PMID Version="1">22951344</PMID></CommentsCorrections><CommentsCorrections RefType="Cites"><RefSource>Proc Biol Sci. 2007 Oct 7;274(1624):2385-91</RefSource><PMID Version="1">17669726</PMID></CommentsCorrections><CommentsCorrections RefType="Cites"><RefSource>Proc Natl Acad Sci U S A. 2010 Oct 26;107(43):18366-70</RefSource><PMID Version="1">20974927</PMID></CommentsCorrections></CommentsCorrectionsList><OtherID Source="NLM">PMC4578264</OtherID></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="received"><Year>2015</Year><Month>01</Month><Day>27</Day></PubMedPubDate><PubMedPubDate PubStatus="accepted"><Year>2015</Year><Month>09</Month><Day>06</Day></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2015</Year><Month>9</Month><Day>24</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2015</Year><Month>9</Month><Day>24</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2015</Year><Month>9</Month><Day>24</Day><Hour>6</Hour><Minute>1</Minute></PubMedPubDate></History><PublicationStatus>epublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">26396739</ArticleId><ArticleId IdType="doi">10.1186/s40462-015-0057-2</ArticleId><ArticleId IdType="pii">57</ArticleId><ArticleId IdType="pmc">PMC4578264</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
