    • Local and regional determinants of colonisation-extinction dynamics of a riparian mainland-island root vole metapopulation 

      Glorvigen, Petter; Andreassen, Harry Peter; Ims, Rolf Anker (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      The role of local habitat geometry (habitat area and isolation) in predicting species distribution has become an increasingly more important issue, because habitat loss and fragmentation cause species range contraction and extinction. However, it has also become clear that other factors, in particular regional factors (environmental stochasticity and regional population dynamics), should be taken ...

    • Vole population cycles and the role of colonisation 

      Glorvigen, Petter (Doctoral thesis; Doktorgradsavhandling, 2012-12-06)
      The multiannual population cycles in small rodents have triggered an intense debate between proponents of population-intrinsic and community-extrinsic factors as the cycle generating mechanisms. A well-known challenge is the apparent absence of vole individuals during the low phase of the population cycle and the fact that most studies addressing vole and lemming behaviour and demography are conducted ...
