      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 ...
