    • Cratering behaviour and faecal C:N ratio in relation to seasonal snow-pack characteristics in a High-Arctic ungulate 

      Beumer, Larissa Teresa; Varpe, Øystein; Hansen, Brage Bremset (Journal article; Peer reviewed, 2017)
      Snow and ice determine winter forage availability for Arctic herbivores. Winter precipitation is anticipated to increase, and icing following warm spells and rain-on-snow (ROS) are likely to become more frequent. While ...

    • Five decades of terrestrial and freshwater research at Ny-Ålesund, Svalbard 

      Pedersen, Åshild Ønvik; Convey, P.; Newsham, Kevin K.; Mosbacher, Jesper Bruun; Fuglei, Eva; Ravolainen, Virve; Hansen, Brage Bremset; Jensen, Thomas Correll; Augusti, A.; Biersma, Elisabeth Mackteld; Cooper, Elisabeth J.; Coulson, S.J.; Gabrielsen, Geir W.; Gallet, Jean-Charles; Karsten, U.; Kristiansen, Silje Marie; Svenning, Mette Marianne; Tveit, Alexander; Uchida, M.; Baneschi, I.; Calizza, E.; Cannone, N.; de Goede, E.M.; Doveri, M.; Elster, J.; Giamberini, M.S.; Hayashi, K.; Lang, Simone; Lee, Y.K.; Nakatsubo, T.; Pasquali, V.; Paulsen, I.M.G.; Pedersen, Christina Alsvik; Peng, F.; Provenzale, A.; Pushkareva, E.; Sandström, C.A.M.; Sklet, Vera; Stach, A.; Tojo, M.; Tytgat, B.; Tømmervik, Hans; Velazquez, D.; Verleyen, E.; Welker, J.M.; Yao, Y.-F.; Loonen, M.J.J.E. (Peer reviewed; Journal article, 2022)
      For more than five decades, research has been conducted at Ny-Ålesund, in Svalbard, Norway, to understand the structure and functioning of High- Arctic ecosystems and the profound impacts on them of environmental change. ...

    • Hair mineral levels as indicator of wildlife demographics?—a pilot study of muskoxen 

      Mosbacher, Jesper Bruun; Desforges, Jean-Pierre; Michelsen, Anders; Hansson, Sophia V.; Stelvig, Mikkel; Eulaers, Igor; Sonne, Christian; Dietz, Rune; Jenssen, Bjørn Munro; Ciesielski, Tomasz Maciej; Lierhagen, Syverin; Flaten, Trond Peder; Le Roux, Gael; Aggerbeck, Marie R.; Schmidt, Niels Martin (Peer reviewed; Journal article, 2022)
      The tight linkage between mineral status and health and demographics in animals is well documented. Mineral deficiencies have been coupled to population declines in wildlife. Current practices typically rely on liver, ...

    • Kelp and seaweed feeding by High-Arctic wild reindeer under extreme winter conditions 

      Hansen, Brage Bremset; Aanes, Ronny (Journal article; Peer reviewed, 2012)
      One challenge in current Arctic ecological research is to understand and predict how wildlife may respond to increased frequencies of “extreme” weather events. Heavy rain-on-snow (ROS) is one such extreme phenomenon ...
