    • Circum-Arctic distribution of chemical anti-herbivore compounds suggests biome-wide trade-off in defence strategies in Arctic shrubs 

      Lindén, Elin; te Beest, Mariska; Aubreu, Ilka; Moritz, Thomas; Sundqvist, Maja K.; Barrio, Isabel C.; Boike, Julia; Bryant, John P.; Bråthen, Kari Anne; Buchwal, Agata; Bueno, C. Guillermo; Currier, Alain; Egelkraut, Dagmar Dorothea; Forbes, Bruce C.; Hallinger, Martin; Heijmans, Monique; Hermanutz, Luise; Hik, David S.; Hofgaard, Annika; Holmgren, Milena; Huebner, Diane C.; Høye, Toke T.; Jónsdóttir, Ingibjörg S.; Kaarlejärvi, Elina; Kissler, Emilie; Kumpula, Timo; Limpens, Juul; Myers-Smith, Isla H.; Normand, Signe; Post, Eric; Rocha, Adrian V.; Schmidt, Niels Martin; Skarin, Anna; Soininen, Eeva M; Sokolov, Aleksandr; Sokolova, Natalia; Speed, James David Mervyn; Street, Lorna E.; Tananaev, Nikita; Tremblay, Jean-Pierre; Urbanowicz, Christine; Watts, David A.; Zimmermann, Heike H.; Olofsson, Johan (Peer reviewed; Journal article, 2022)
      Spatial variation in plant chemical defence towards herbivores can help us understand variation in herbivore top–down control of shrubs in the Arctic and possibly also shrub responses to global warming. Less defended, ...

    • Phenology and cover of plant growth forms predict herbivore habitat selection in a high latitude ecosystem 

      Iversen, Marianne; Fauchald, Per; Langeland, Knut; Ims, Rolf Anker; Yoccoz, Nigel Gilles; Bråthen, Kari Anne (Journal article; Peer reviewed, 2014)
      The spatial and temporal distribution of forage quality is among the most central factors affecting herbivore habitat selection. Yet, for high latitude areas, forage quantity has been found to be more important than quality. ...

    • Rangifer management controls a climate-sensitive tundra state transition 

      Bråthen, Kari Anne; Ravolainen, Virve Tuulia; Stien, Audun; Tveraa, Torkild; Ims, Rolf Anker (Journal article; Peer reviewed, 2017)
      Rangifer (caribou/reindeer) management has been suggested to mitigate the temperature- driven transition of Arctic tundra into a shrubland state, yet how this happens is uncertain. Here we study this much focused ecosystem ...
