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 ... -
Local and Regional Determinants of Colonisation- Extinction Dynamics of a Riparian Mainland-Island Root Vole Metapopulation
Glorvigen, Petter; Andreassen, Harry Peter; Ims, Rolf A. (Journal article; 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 ... -
Macroecological patterns of rodent population dynamics shaped by bioclimatic gradients
Soininen, Eeva M; Magnusson, Magnus; Jepsen, Jane Uhd; Eide, Nina Elisabeth; Yoccoz, Nigel Gilles; Angerbjörn, Anders; Breisjøberget, Jo Inge; Ecke, Frauke; Ehrich, Dorothee; Framstad, Erik; Henttonen, Heikki; Hörnfeldt, Birger; Killengreen, Siw Turid; Olofsson, Johan; Oksanen, Lauri; Oksanen, Tarja Maarit; Tveito, Ole Einar Ellingbø; Ims, Rolf A. (Peer reviewed; Journal article, 2024)Long-term studies of cyclic rodent populations have contributed fundamentally to the development of population ecology. Pioneering rodent studies have shown macroecological patterns of population dynamics in relation to ... -
New views on how population-intrinsic and community-extrinsic processes interact during the vole population cycles
Andreassen, Harry Peter; Glorvigen, Petter; Rémy, Alice; Ims, Rolf A. (Journal article; Peer reviewed, 2013)Based on evidence from a series of recent studies linking behaviour to demography in experimental vole populations we propose how intrinsic and extrinsic factors interact through the various phases of the multi-annual ... -
The role of colonization in the dynamics of patchy populations of a cyclic vole species
Glorvigen, Petter; Gundersen, Gry; Andreassen, Harry Peter; Ims, Rolf A. (Peer reviewed; Journal article, 2013)The crash phase of vole populations with cyclic dynamics regularly leads to vast areas of uninhabited habitats. Yet although the capacity for cyclic voles to re-colonize such empty space is likely to be large and predicted ... -
Why Do the Boreal Forest Ecosystems of Northwestern Europe Differ from Those of Western North America?
Boonstra, Rudy; Andreassen, Harry Peter; Boutin, Stan; Husek, Jan; Ims, Rolf A.; Krebs, Charles J.; Skarpe, Christina; Wabakken, Petter (Journal article; Peer reviewed, 2016)The boreal forest is one of the largest terrestrial biomes on Earth. Conifers normally dominate the tree layer across the biome, but other aspects of ecosystem structure and dynamics vary geographically. The cause of the ...
