    • Feeding at the front line: Interannual variation in the use of glacier fronts by foraging black-legged kittiwakes 

      Bertrand, Philip; Strøm, Hallvard; Bêty, Joël; Steen, Harald; Kohler, Jack; Vihtakari, Mikko; Van Pelt, Ward; Yoccoz, Nigel Gilles; Hop, Haakon; Harris, Stephanie M.; Patrick, Samantha C.; Assmy, Philipp; Wold, Anette; Duarte, Pedro; Moholdt, Geir; Descamps, Sébastien (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-28)
      Tidewater glacier fronts can represent important foraging areas for Arctic predators. Their ecological importance is likely to change in a warmer Arctic. Their profitability and use by consumers are expected to vary in time, but the underlying mechanisms driving such variation remain poorly known. The subglacial plume, originating from meltwater discharge, is responsible for the entrainment and ...

    • Fine-scale spatial segregation in a pelagic seabird driven by differential use of tidewater glacier fronts 

      Bertrand, Philip; Bêty, Joël; Yoccoz, Nigel G.; Fortin, Marie-Josée; Strøm, Hallvard; Steen, Harald; Kohler, Jack; Harris, Stephanie M.; Patrick, Samantha C.; Chastel, Olivier; Blévin, P.; Hop, Haakon; Moholdt, Geir; Maton, Joséphine; Descamps, Sébastien (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-11)
      In colonially breeding marine predators, individual movements and colonial segregation are influenced by seascape characteristics. Tidewater glacier fronts are important features of the Arctic seascape and are often described as foraging hotspots. Albeit their documented importance for wildlife, little is known about their structuring effect on Arctic predator movements and space use. In this study, ...
