    • A brain and a head for a different habitat: Size variation in four morphs of Arctic charr (Salvelinus alpinus (L.)) in a deep oligotrophic lake 

      Tamayo, Ana-Maria Peris; Devineau, Olivier; Præbel, Kim; Kahilainen, Kimmo Kalevi; Østbye, Kjartan (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-25)
      Adaptive radiation is the diversification of species to different ecological niches and has repeatedly occurred in different salmonid fish of postglacial lakes. In Lake Tinnsjøen, one of the largest and deepest lakes in Norway, the salmonid fish, Arctic charr (<i>Salvelinus alpinus</i> (L.)), has likely radiated within 9,700 years after deglaciation into ecologically and genetically segregated ...

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

      Neby, Magne; Ims, Rolf Anker; Kamenova, Stefaniya Kamenova; Devineau, Olivier; Soininen, Eeva Marjatta (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-17)
      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 ways. For instance, if the biomass of preferred food plants is reduced after a peak phase of a cycle, rodent diets can be expected to become dominated by less preferred food plants, ...

    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-26)
      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 resides in the potential to infer a quantitative relationship between sequence read proportions and biomass of ingested food. However, this relationship’s robustness is highly dependent ...
