    • Gut microbiome biogeography in reindeer supersedes millennia of ecological and evolutionary separation 

      Kamenova, Stefaniya; de Muinck, Eric; Veiberg, Vebjørn; Utsi, Tove Hilde Ågnes; Steyaert, Sam; Albon, Steve; Loe, Leif Egil; Trosvik, Pål (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-29)
      Ruminants are dependent on their gut microbiomes for nutrient extraction from plant diets. However, knowledge about the composition, diversity, function, and spatial structure of gut microbiomes, especially in wild ruminants, is limited, largely because analysis has been restricted to faeces or the rumen. In two geographically separated reindeer subspecies, 16S rRNA gene amplicon sequencing revealed ...

    • 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 ...

    • Location of studies and evidence of effects of herbivory on Arctic vegetation: a systematic map

      Herbivores modify the structure and function of tundra ecosystems. Understanding their impacts is necessary to assess the responses of these ecosystems to ongoing environmental changes. However, the effects of herbivores on plants and ecosystem structure and function vary across the Arctic. Strong spatial variation in herbivore effects implies that the results of individual studies on herbivory ...
