    • Human-animal agency in reindeer management: Sami herders perspectives on vegetation dynamics under climate change 

      Horstkotte, Tim; Utsi, Tove Aagnes; Larsson-Blind, Åsa; Burgess, Peter; Johansen, Bernt; Kayhko, Jukka; Oksanen, Lauri Kalervo; Forbes, B.C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-13)
      Many primary livelihoods in Arctic and sub-Arctic regions experience accelerating effects of environmental change. The often close connection between indigenous peoples and their respective territories allows them to make detailed observations of how these changes transform the landscapes where they practice their daily activities. Here, we report Sámi reindeer herders’ observations based on their ...

    • Predator–rodent–plant interactions along a coast–inland gradient in Fennoscandian tundra 

      Oksanen, Lauri Kalervo (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-09)
      Spatial variation in the strength of trophic cascades in arctic tundra has been related to flows of subsidies across ecosystem boundaries. Here, we ask whether the input of marine subsidies in tundra systems would cause spatial variation in the strength of rodent–plant interactions between coastal areas, where predators have access to marine-derived resources, and non-subsidized inland areas of ...

    • Reindeer and tundra in a changing world: threats and opportunities (språk: engelsk og samisk) 

      Oksanen, Lauri Kalervo (Conference object; Konferansebidrag, 2015-10-15)

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

      Virtanen, Risto; Oksanen, Lauri Kalervo; Oksanen, Tarja Maarit; Cohen, Juval; Forbes, Bruce C.; Johansen, Bernt; Käyhkö, Jukka; Olofsson, Johan; Pulliainen, Jouni; Tømmervik, Hans (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-15)
      According to some treatises, arctic and alpine sub-biomes are ecologically similar, whereas others find them highly dissimilar. Most peculiarly, large areas of northern tundra highlands fall outside of the two recent subdivisions of the tundra biome. We seek an ecologically natural resolution to this long-standing and far-reaching problem. We studied broad-scale patterns in climate and ...
