Comparative foraging ecology of a tropical seabird community of the Seychelles, western Indian OceanTropical seabirdsForaging ecologyDietTemporal variationsFood shortageWestern Indian Oceanhttp://www.int-res.com/abstracts/meps/v374/p259-272/We studied the foraging ecology of a tropical seabird community in 2 islands of the Seychelles from 2005 to 2007. Chick dietary samples were used to compare feeding habits among species and assess inter-annual and seasonal variations in diet. Fish prey dominated the diet of the community (68 to 100% of prey consumed), although cephalopods were present in 61.3, 40.0, 27.1 and 32.9% of the food samples from white-tailed tropicbirds, sooty terns, brown noddies and wedgetailed shearwaters, respectively. We found high diet overlap between species (Mullidae fish being the first prey consumed [30 to 90%] for all species except for the white-tailed tropicbird [<2%]) but some segregation in prey length. Other important prey were Exocoetidae, Carangidae, Scombridae and Clupeidae mainly for white-tailed tropicbirds, sooty terns and brown noddies, Hemiramphidae and Coryphaenidae for white-tailed tropicbirds, and Engraulidae and fish larvae for lesser noddies and Audubon’s shearwaters. Despite some inter-annual and seasonal variations in diet, these were not consistent within the community. Responses of the seabird community to an environmental perturbation that negatively affected chick growth and breeding success of lesser noddies emphasised the higher vulnerability of species with smaller foraging ranges and/or with lower ability to switch diet (lesser noddy, roseate tern) compared to less range-restricted and/or more opportunistic ones (white-tailed tropicbird, brown noddy, sooty tern, white tern). Although situated in a tropical region, the food availability in the Seychelles seems to be predictable at a large (annual) temporal scale, but highly unpredictable at a small intra-seasonal or daily) temporal scale.Fundação para a Ciência e Tecnologia (SFRH/BD/16706/2004); Western Indian Ocean Marine Science Association (Marine Science for Management Grant, MASMA/AG/2004/04); Agence National pour la Recherche (Programme REMIGE – ANR Biodiversité 2005-011).nter-Research2009-01-13info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://hdl.handle.net/10316/10231http://hdl.handle.net/10316/10231https://doi.org/10.3354/meps07713engMar Ecol Prog Ser 374: 259–272, 2009doi: 10.3354/meps07713Catry, TeresaRamos, Jaime A.Jaquemet, SébastienFaulquier, LucieBerlincourt, MaudHauselmann, AntoinePinet, PatrickLe Corre, Matthieuinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2020-11-06T17:00:28Zoai:estudogeral.uc.pt:10316/10231Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T20:55:24.426024Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
