    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-13)
      <ol> <li>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 foraging behaviour and the occurrence of individual tactics in relation to resources distribution can help explain differences in individual fitness, and ultimately identify important ...

    • Pelagic food web structure in high nutrient low chlorophyll (HNLC) and naturally iron fertilized waters in the Kerguelen Islands region, Southern Ocean 

      Hunt, Brian P. V.; Espinasse, Boris Dristan; Pakhomov, Evgeny A.; Cherel, Yves; Cotté, Cédric; Delegrange, Alice; Henschke, Natasha (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-19)
      The Kerguelen Plateau is a region of natural iron fertilization in the Southern Ocean, within the typically iron limited High Nutrient Low Chlorophyll (HNLC) waters of the eastward flowing Antarctic Circumpolar Current. Between 26 February and 19 March 2018, the MOBYDICK expedition investigated pelagic ecosystem dynamics in the Kerguelen Island region on the northern plateau during the post-phytoplankton ...

    • Stable Isotope Trajectory Analysis (SITA): A new approach to quantify and visualize dynamics in stable isotope studies 

      Sturbois, Anthony; Cucherousset, Julien; De Cáceres, Miquel; Desroy, Nicolas; Riera, Pascal; Carpentier, Alexandre; Quillien, Nolwenn; Grall, Jacques; Espinasse, Boris Dristan; Cherel, Yves; Schaal, Gauthier (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-16)
      Ecologists working with stable isotopes have to deal with complex datasets including temporal and spatial replication, which makes the analysis and the representation of patterns of change challenging, especially at high resolution. Due to the lack of a commonly accepted conceptual framework in stable isotope ecology, the analysis and the graphical representation of stable isotope spatial and ...
