    • Cascading effects of moose (Alces alces) management on birds 

      Mathisen, Karen Marie; Skarpe, Christina (Journal article; Peer reviewed, 2011)
      Large herbivores often have key functions in their ecosystems, and may change ecosystem processes with cascading effects on other animals. The mechanisms often involve relocations of resources of various kinds, including ...
    • Contrasting responses of two passerine bird species to moose browsing 

      Mathisen, Karen Marie; Pedersen, Simen; Nilsen, Erlend Birkeland; Skarpe, Christina (Journal article; Peer reviewed, 2012)
      Large herbivores may modify the ecosystem in a way that affects habitat quality and resource availability for other fauna. The increase in wild ungulate abundance in many areas may therefore lead to ecosystem changes, affecting ...

      I 1995 byrja me å studera elg og trafikk i Østerdalen. Då ulv etablerte seg i studieområdet, undersøkte me verknaden av ulv på elg. Sidan studerte me elgøkonomi før me såg på verknaden av elgfôring i samarbeid med Stor-Elvdal ...
    • En integrerad förvaltning av älg och skog 

      Skarpe, Christina; Mathisen, Karen Marie (Chapter; Peer reviewed, 2014)
      I detta kapitel diskuterar vi möjligheten att i ökad omfattning utnyttja både värdet av skog och av älg genom en aktiv integrerad förvaltning av båda resurserna. En sådan samförvaltning bygger på att hålla ett ...
    • Effects of forest roads on oak trees via cervid habitat use and browsing 

      Mathisen, Karen Marie; Wójcicki, Adam; Borowski, Zbigniew (Journal article; Peer reviewed, 2018)
      Roads can affect animals in several ways, by affecting movement, space use, foraging behavior and mortality. As roads often have a negative effect on populations of birds and mammals, their effects are important for wildlife ...
    • Forest rehabilitation, biodiversity and ecosystem services in Java, Indonesia 

      Udayana, Cicik (PhD thesis in applied ecology;17, Doctoral thesis, 2019)
      Planting av trær i degraderte områder er en viktig restaureringsstrategi for å øke forsyningen av økosystemtjenester. Når vi planter spesifikke arter for enkelte formål, for eksempel tømmerproduksjon, kaller vi det ...
    • Giraffe browsing in response to plant traits 

      Mahenya, Obeid; Ndjamba, Johannes Kambinda; Mathisen, Karen Marie; Skarpe, Christina (Journal article; Peer reviewed, 2016)
      Intake rates by large herbivores are governed by among other things plant traits. We used Masai giraffe (Giraffa camelopardalis tippelskirchi Matschie) as study animals, testing whether they as very large browsers would ...
    • Hierarchical foraging by giraffe in a heterogeneous savannah, Tanzania 

      Mahenya, Obeid; Mathisen, Karen Marie; Andreassen, Harry Peter; Skarpe, Christina (Journal article; Peer reviewed, 2016)
      Understanding foraging decisions made by wildlife at different spatio-temporal scales is important for wildlife management and conservation. We tested whether forag- ing decisions by Masai giraffe ( Giraffa ...
    • Hvordan elgens aktiviteter rundt fôringsplasser påvirker vegetasjon, småfugler og mus 

      Mathisen, Karen Marie; Pedersen, Simen (Chapter; Peer reviewed, 2014)
      Vi har studert hvordan elgbeiting og fôringsplasser for elg påvirker vegetasjon, småfugler og mus i Stor-Elvdal i perioden 2004-2011. Det viser seg at fôringsplasser påvirker elgens fordeling i landskapet om vinteren ...
    • Indirect effects of moose on the birds and the bees 

      Mathisen, Karen Marie (Acta Universitatis agriculturae Sueciae;2011:13, Doctoral thesis, 2011)
      Large herbivores are important drivers of ecosystem processes, affecting plant species richness and composition, primary productivity, habitat structure as well as nutrient cycling. Large herbivore activities may therefore ...
    • Is heavy browsing a threat to biodiversity in a boreal ecosystem? 

      Milner, Jos M.; Mathisen, Karen Marie (Conference object, 2010-03)
      Herbivore numbers have been increasing across Europe and North America in recent decades, with implications for whole ecosystems including impacts on biodiversity. Moose populations in Scandinavia are no exception, leading ...
    • 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 ...
    • Shoot growth responses at supplementary feeding stations for moose in Norway 

      Mathisen, Karen Marie; Remy, Amadine; Skarpe, Christina (Journal article; Peer reviewed, 2015)
      Moose browsing pressure in the vicinity of supplementary winter feeding stations eventually declines over time. It is believed that continual winter browsing over multiple years causes locally reduced shoot growth and ...
