• Antarctic petrels ‘on the ice rocks’: wintering strategy of an Antarctic seabird 

      Delord, Karine; Kato, A.; Tarroux, Arnaud; Orgeret, F.; Cotté, C.; Ropert-Coudert, Yan; Cherel, Y.; Descamps, Sebastien (Peer reviewed; Journal article, 2020)
      There is a paucity of information on the foraging ecology, especially individual use of sea-ice features and icebergs, over the non-breeding season in many seabird species. Using geolocators and stable isotopes, we defined ...

    • Foraging tactics in dynamic sea-ice habitats affect individual state in a long-ranging seabird 

      Tarroux, Arnaud; Cherel, Yves; Fauchald, Per; Kato, Akiko; Love, Oliver P.; Ropert-Coudert, Yan; Spreen, Gunnar; Varpe, Øystein; Weimerskirch, Henri; Yoccoz, Nigel; Zahn, Sandrine; Descamps, Sebastien (Peer reviewed; Journal article, 2020)
      1. Individual heterogeneity in diet and foraging behaviour is common in wild animal populations, and can be a strong determinant of how populations respond to environmental changes. Within populations, variation in ...
    • Individual migration strategy fidelity but no habitat specialization in two congeneric seabirds 

      Merkel, Benjamin; Descamps, Sebastien; Yoccoz, Nigel; Grémillet, David; Daunt, Francis; Erikstad, Kjell E; Ezhov, Aleksey V.; Harris, Mike P.; Gavrilo, Maria; Lorentsen, Svein Håkon; Reiertsen, Tone Kristin; Steen, Harald; Systad, Geir Helge Rødli; Þórarinsson, Þorkell Lindberg; Wanless, Sarah; Strøm, Hallvard (Peer reviewed; Journal article, 2020)
      Abstract Aim: In migratory species, individuals often use fixed and individual-specific migration strategies, which we term individual migration strategy fidelity (IMSF). Our goal was to test if guillemots have flexible ...
    • Light-level geolocators reveal spatial variations in interactions between northern fulmars and fisheries 

      Dupuis, Benjamin; Amélineau, Françoise; Tarroux, Arnaud; Bjørnstad, Oskar; Bråthen, Vegard Sandøy; Danielsen, Jóhannis; Descamps, Sebastien; Fauchald, Per; Hallgrimsson, Gunnar Thor; Hansen, Erpur Snær; Helberg, Morten; Helgason, Halfdan Helgi; Jónsson, Jón Einar; Kolbeinsson, Yann; Lorentzen, Erlend; Thompson, Paul; Thórarinsson, Thorkell Lindberg; Strøm, Hallvard (Peer reviewed; Journal article, 2021)
      Seabird−fishery interactions are a common phenomenon of conservation concern. Here, we highlight how light-level geolocators provide promising opportunities to study these interactions. By examining raw light data, it ...
