    • Variable responses of carbon and nitrogen contents in vegetation and soil to herbivory and warming in high-Arctic tundra 

      Petit Bon, Matteo; Bøhner, Hanna; Bråthen, Kari Anne; Ravolainen, Virve; Jónsdóttir, Ingibjörg Svala (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-21)
      Chemical responses of tundra vegetation and tundra soil to environmental changes are likely to differ, with implications for ecosystem functioning, yet they are rarely compared. Here, we aimed at comparing sensitivity and magnitude of short-term carbon and nitrogen responses of three main tundra ecosystem compartments: vascular plants, mosses, and soil, to two environmental perturbations: herbivore ...

    • What are the impacts of reindeer/caribou (Rangifer tarandus L.) on arctic and alpine vegetation? A systematic review protocol 

      Bernes, Claes; Bråthen, Kari Anne; Forbes, Bruce C.; Hofgaard, Annika; Moen, Jon; Speed, James David Mervyn (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Abstract Background: Reindeer and caribou (both belonging to the species Rangifer tarandus L.) are among the most important large herbivores in Eurasia’s and North America’s arctic, alpine and boreal zones. In Sweden, the impact of reindeer grazing on arctic and alpine vegetation has recently been re-evaluated. In the 1990s, records of grazing-related vegetation degradation helped to form a ...

    • What are the impacts of reindeer/caribou (Rangifer tarandus L.) on arctic and alpine vegetation? A systematic review 

      Bernes, Claes; Bråthen, Kari Anne; Forbes, Bruce C.; Speed, James David Mervyn; Moen, Jon (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-23)
      Background: The reindeer (or caribou, Rangifer tarandus L.) has a natural range extending over much of Eurasia’s and North America’s arctic, alpine and boreal zones, yet its impact on vegetation is still unclear. This lack of a common understanding hampers both the management of wild and semi-domesticated reindeer populations and the preservation of biodiversity. To achieve a common platform, we ...
