      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 ...
    • 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 ...
    • Long-term tracking of an Arctic-breeding seabird indicates high fidelity to pelagic wintering areas 

      Léandri-Breton, Don-Jean; Tarroux, Arnaud; Elliott, Kyle H.; Legagneux, Pierre; Angelier, Frédéric; Blévin, Pierre; Bråthen, Vegard Sandøy; Fauchald, Per; Goutte, Aurélie; Jouanneau, William; Tartu, Sabrina; Moe, Børge; Chastel, Olivier (Peer reviewed; Journal article, 2021)
      Site fidelity is driven by predictable resource distributions in time and space. However, intrinsic factors related to an individual’s physiology and life-history traits can contribute to consistent foraging behaviour and ...
    • Multi-colony tracking of two pelagic seabirds with contrasting flight capability illustrates how windscapes shape migratory movements at an ocean-basin scale 

      Amelineau, Francoise; Tarroux, Arnaud; Lacombe, Simon; Bråthen, Vegard Sandøy; Descamps, Sebastien; Ekker, Morten; Fauchald, Per; Johansen, Malin; Moe, Børge; Anker-Nilssen, Tycho; Bogdanova, Maria I.; Bringsvor, Ingar S.; Chastel, Olivier; Christensen-Dalsgaard, Signe; Daunt, Francis; Dehnhard, Nina; Erikstad, Kjell E.; Ezhov, Aleksey; Gavrilo, Maria; Hansen, Erpur S.; Harris, Mike P.; Helgason, Halfdan Helgi; Langset, Magdalene; Léandri-Breton, Don-Jean; Lorentsen, Svein-Håkon; Merkel, Benjamin; Newell, Mark; Olsen, Bergur; Reiertsen, Tone Kristin; Systad, Geir Helge Rødli; Thorarinsson, Thorkell L.; Åström, Jens; Strøm, Hallvard (Peer reviewed; Journal article, 2023)
      Migration is a common trait among many animals allowing the exploitation of spatiotemporally variable resources. It often implies high energetic costs to cover large distances, for example between breeding and wintering ...
    • Predicting Foraging Habitat of European Shags - A Multi-Year and Multi-Colony Tracking Approach to Identify Important Areas for Marine Conservation 

      Dehnhard, Nina; Mattisson, Jenny; Tarroux, Arnaud; Anker-Nilssen, Tycho; Lorentsen, Svein-Håkon; Christensen-Dalsgaard, Signe (Peer reviewed; Journal article, 2022)
      Human activity in the coastal zone is increasing worldwide, putting a number of seabird species under pressure. Norway is no exception to this development, and with > 35% of the NE Atlantic population of the currently ...
