    • 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 ...

    • Reindeer turning maritime: Ice-locked tundra triggers changes in dietary niche utilization 

      Hansen, Brage Bremset; Lorentzen, Jon Runar; Welker, Jeffrey M.; Varpe, Øystein; Aanes, Ronny; Beumer, Larissa Teresa; Pedersen, Åshild Ø. (Journal article; Peer reviewed, 2019)
      The rapid warming of the Arctic may not only alter species’ abundances and distributions, but likely also the trophic interactions within and between ecosystems. On the high‐arctic tundra, extreme warm spells and associated ...

    • Sea or summit? Wild reindeer spatial responses to changing high-arctic winters 

      Pedersen, Åshild Ønvik; Beumer, Larissa Teresa; Aanes, Ronny; Hansen, Brage Bremset (Peer reviewed; Journal article, 2021)
      Because of climate change, wildlife is facing altered environments, including profound shifts in temperature and precipitation regimes. In snow-dominated ecosystems, winter warming and resulting changes in snowpack properties ...

    • Towards rainy Arctic winters: effects of experimental icing on tundra plants and their soil conditions 

      Le Moullec, Mathilde; Isaksen, Ketil; Petit Bon, Matteo; Jónsdóttir, Ingibjörg Svala; Varpe, Øystein; Hendel, Anna-Lena; Beumer, Larissa Teresa; Hansen, Brage Bremset (MET report;, Research report, 2019)
      Global warming comes with more frequent extreme climate events. In the Arctic, extreme warm spells with heavy rain-on-snow events in winter can cause dramatic changes to the snow-pack and encapsulate the vegetation in thick ...
