    • 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 ...
    • Where do the treeless tundra areas of northern highlands fit in the global biome system: toward an ecologically natural subdivision of the tundra biome
