    • Long-term browsing impact around diversionary feeding stations for moose in Southern Norway 

      van Beest, Floris Michiel; Gundersen, Hege; Mathisen, Karen Marie; Milner, Jos M.; Skarpe, Christina (Conference object, 2010)
    • Long-term effects of supplementary feeding of moose on browsing impact at a landscape scale 

      Mathisen, Karen Marie; Milner, Jos M.; van Beest, Floris M.; Skarpe, Christina (Journal article; Peer reviewed, 2014)
      Supplementary feeding of wildlife is a common management practice, increasingly used to reduce or divert herbivore impact from sensitive habitats, forestry or agriculture. The landscape-scale spatial distribution of ...
    • Moose–tree interactions: rebrowsing is common across tree species 

      Mathisen, Karen Marie; Milner, Jocelyn Margarey; Skarpe, Christina (Journal article; Peer reviewed, 2017)
      Background Plant strategies to resist herbivory include tolerance and avoidance. Tolerance strategies, such as rapid regrowth which increases the palatability of new shoots, can lead to positive feedback loops between ...
    • Roads, forestry, and wolves interact to drive moose browsing behavior in Scandinavia 

      Loosen, Anne Elizabeth; Devineau, Olivier; Zimmermann, Barbara; Cromsigt, Joris P. G. M.; Pfeffer, Sabine; Skarpe, Christina; Mathisen, Karen Marie (Peer reviewed; Journal article, 2021)
      As wild ungulate densities increase across Europe and North America, plant–herbivore interactions are increasingly important from ecological and economic perspectives. These interactions are particularly significant where ...
