Bears are simply voles writ large: social structure determines the mechanisms of intrinsic population regulation in mammals
Odden, Morten; Ims, Rolf Anker; Støen, Ole-Gunnar; Swenson, Jon; Andreassen, Harry Peter (Journal article; Peer reviewed, 2014)The literature reveals opposing views regarding the importance of intrinsic population regulation in mammals. Different models have been proposed; adding importance to contrasting life histories, body sizes and social ... -
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 ... -
Issues of under-representation in quantitative DNA metabarcoding weaken the inference about diet of the tundra vole Microtus oeconomus
Neby, Magne; Kamenova, Stefaniya; Devineau, Olivier; Ims, Rolf Anker; Soininen, Eeva M (Peer reviewed; Journal article, 2021)During the last decade, methods based on high-throughput sequencing such as DNA metabarcoding have opened up for a range of new questions in animal dietary studies. One of the major advantages of dietary metabarcoding ... -
A semi-automatic workflow to process images from small mammal camera traps
Böhner, Hanna; Kleiven, Eivind Flittie; Ims, Rolf Anker; Soininen, Eeva M (Peer reviewed; Journal article, 2023-06-05)Camera traps have become popular for monitoring biodiversity, but the huge amounts of image data that arise from camera trap monitoring represent a challenge and artificial intelligence is increasingly used to automatically ... -
Settlement in empty versus occupied habitats : an experimental study on bank voles
Glorvigen, Petter; Bjørnstad, Ottar N.; Andreassen, Harry Peter; Ims, Rolf Anker (Journal article; Peer reviewed, 2012)Abstract Despite the recognised im 23 portance of colonisation (settlement in empty habitats) and immigration (settlement in an established population) to species persistence and evolution few have investigated these ... -
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 Anker; Krebs, Charles J.; Skarpe, Christina; Wabakken, Petter (Peer reviewed; Journal article, 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 ...
