    • Comparison of methods for revegetation of vehicle tracks in High Arctic tundra on Svalbard. 

      Neby, Magne; Semenchuk, Philipp; Neby, Erica; Cooper, Elisabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-03)
      Natural regeneration after anthropogenic disturbance is slow in the tundra biome, but assisted regeneration can help speed up this process. A tracked off-road vehicle damaged a High Arctic dwarf shrub heath in Svalbard in May 2009, drastically reducing the vegetation cover, soil seed banks, and incoming seed rain. We assisted regeneration the following year using six different revegetation treatments ...

    • 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 ...

    • Small rodent population cycles and plants – after 70 years, where do we go? 

      Soininen, Eeva M; Neby, Magne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-12)
      Small rodent population cycles characterise northern ecosystems, and the cause of these cycles has been a long-lasting central topic in ecology, with trophic interactions currently considered the most plausible cause. While some researchers have rejected plant–herbivore interactions as a cause of rodent cycles, others have continued to research their potential roles. Here, we present an overview ...
