    • Three approaches to estimate wolf Canis lupus predation rates on moose Alces alces populations 

      Gundersen, Hege; Solberg, Erling J.; Wabakken, Petter; Storaas, Torstein; Zimmermann, Barbara; Andreassen, Harry Peter (Peer reviewed; Journal article, 2008)
      Abstract We employed three different methods to estimate predation rates on moose in a newly colonized wolf territory in Norway. In the first two methods, we estimated predation rates based on the difference in calf/cow ...

    • Tildelt, sett og felt elg i forhold til ulveforekomst i Norge og Sverige. Utredning om ulv og elg del 1 

      Wikenros, Camilla; Zimmermann, Barbara; Sand, Håkan; Månsson, Johan; Maartmann, Erling; Eriksen, Ane; Wabakken, Petter (Skriftserien;22/2019, Research report, 2019)
      Predasjon fra store rovdyr og jakt er de to viktigste faktorene som styrer dynamikken i mange hjorteviltpopulasjoner verden over. Gjenetableringen av ulv på den skandinaviske halvøya har møtt hard motstand fra mange hold, ...

    • Ulv som skadegjører på bufe, tamrein og hund i Norge: skadehistorikk og skadepotensiale i forhold til ulvens spredningsmønster 

      Wabakken, Petter; Maartmann, Erling; Eriksen, Ane; Zimmermann, Barbara; Flagstad, Øystein; Liberg, Olof; Sand, Håkan; Wikenros, Camilla (Research report, 2017)
      Etter reetableringen av ulvebestanden i Skandinavia på 1980-tallet har det vært konflikter knyttet til sameksistensen mellom ulv og mennesker. Konfliktene gjelder i stor grad tap av beitedyr og hunder, menneskers frykt for ...

    • Ulven som rovdyr på klauvvilt i Skandinavia

      Den grunnleggende enheten i en ulveflokk, også kalt familiegruppe, består av det revirmarkerende paret med en lederhann og en ledertispe samt deres avkom fra siste yngling og/eller tidligere valpekull. Flokkens gruppeatferd ...

    • Ungulate-adapted forestry shows promise for alleviating pine browsing damage 

      Loosen, Anne Elizabeth; Devineau, Olivier; Skarpe, Christina; Zimmermann, Barbara; Cromsigt, Joris; Mathisen, Karen Marie (Peer reviewed; Journal article, 2021)
      High densities of ungulates can increase human-wildlife conflicts. Where forestry is an important economy, intensive browsing can lead to browsing damage, resulting in volume losses, poor stand regeneration, and reduced ...
