      1. Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in ...
    • Changing contributions of stochastic and deterministic processes in community assembly over a successional gradient 

      Måren, Inger Elisabeth; Kapfer, Jutta; Aarrestad, Per Arild; Grytnes, John-Arvid; Vandvik, Vigdis (Journal article; Peer reviewed, 2017)
      Successional dynamics in plant community assembly may result from both deterministic and stochastic ecological processes. The relative importance of different ecological processes is expected to vary over the successional ...
    • Gammalnorsk sau og skjøtsel av kystlynghei – restaurering av gammal lynghei 

      Velle, Liv Guri; Nilsen, Liv S.; Vandvik, Vigdis; Thorvaldsen, Pål; Norderhaug, Ann; Øpstad, Samson (NIBIO POP;3(33) 2017, Others, 2017-12)
      Kystlynghei er eit kulturlandskap som i dag er på raudlista over norske naturtypar. Ein av dei største trugslane er opphøyr av tradisjonell beitebruk og lyngsviing, og ein har i dag fleire lyngheier i dårleg hevd. Interessa ...
    • Gammalnorsk sau og skjøtsel av kystlynghei – revegetering etter lyngsviing 

      Velle, Liv Guri; Thorvaldsen, Pål; Vandvik, Vigdis; Nilsen, Liv S.; Norderhaug, Ann; Øpstad, Samson (NIBIO POP;3(32) 2017, Others, 2017-12)
      Lyngsviing er ei viktig skjøtselsform for å legge til rette for gode beiteforhold i kystlyngheia. Kunnskap om kva slags artar som veks fram etter sviing og kor fort desse artane kjem tilbake, er viktig for å få god bruk ...
