    • From individuals to population cycles: the role of extrinsic and intrinsic factors in rodent populations 

      Radchuk, Viktoriia; Ims, Rolf A.; Andreassen, Harry Peter (Journal article; Peer reviewed, 2016)
      Rodent population cycles have fascinated scientists for a long time. Among various hypotheses, an interaction of an extrinsic factor (predation) with intrinsic factors (e.g., sociality and dispersal) was suggested to ...

    • General Experience Rather Than of Local Knowledge is Important for Grouse Hunters Bag Size 

      Asmyhr, Lasse; Willebrand, Tomas; Hörnell-Willebrand, Maria (Journal article; Peer reviewed, 2012)
      Wildlife harvest management requires an understanding of hunter behavioral interactions with the game. Hunter harvest is indicated to be more dependent on experience and attitudes than game abundance. We tested how the ...

    • The impact of human land use and landscape productivity on population dynamics of red fox in southeastern Norway 

      Jahren, Torfinn; Odden, Morten; Linnell, John Durrus; Panzacchi, Manuela (Peer reviewed; Journal article, 2020)
      In the boreal forest, the red fox (Vulpes vulpes) is a key species due to its many strong food web linkages and its exploitation of niches that form in the wake of human activities. Recent altitudinal range expansion and ...

    • Is the diet cyclic phase-dependent in boreal vole populations? 

      Neby, Magne; Ims, Rolf Anker; Kamenova, Stefaniya Kamenova; Devineau, Oliver; Soininen, Eeva Marjatta (Peer reviewed; Journal article, 2024)
      Herbivorous rodents in boreal, alpine and arctic ecosystems are renowned for their multi-annual population cycles. Researchers have hypothesised that these cycles may result from herbivore–plant interactions in various ...

    • Population cycles and outbreaks of small rodents: ten essential questions we still need to solve 

      Andreassen, Harry Peter; Sundell, Janne; Ecke, Fraucke; Halle, Stefan; Haapakoski, Marko; Henttonen, Heikki; Huitu, Otso; Jacob, Jens; Johnsen, Kaja; Koskela, Esa; Luque‑Larena, Juan Jose; Lecomte, Nicolas; Leirs, Herwig; Mariën, Joachim; Neby, Magne; Rätti, Osmo; Sievert, Thorbjörn; Singleton, Grant R.; Cann, Joannes van; Vanden Broecke, Bram; Ylönen, Hannu (Peer reviewed; Journal article, 2021)
      Most small rodent populations in the world have fascinating population dynamics. In the northern hemisphere, voles and lemmings tend to show population cycles with regular fuctuations in numbers. In the southern hemisphere, ...
