    • Highly overlapping winter diet in two sympatric lemming species revealed by DNA metabarcoding 

      Soininen, Eeva M; Gauthier, Gilles; Bilodeau, Frederic; Berteaux, Dominique; Gielly, Ludovic; Taberlet, Pierre; Gussarova, Galina; Bellemain, Eva; Hassel, Kristian; Stenøien, Hans K.; Epp, Laura; Schrøder-Nielsen, Audun; Brochmann, Christian; Yoccoz, Nigel Gilles (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-30)
      Sympatric species are expected to minimize competition by partitioning resources, especially when these are limited. Herbivores inhabiting the High Arctic in winter are a prime example of a situation where food availability is anticipated to be low, and thus reduced diet overlap is expected. We present here the first assessment of diet overlap of high arctic lemmings during winter based on DNA ...

    • Shedding new light on the diet of Norwegian lemmings: DNA metabarcoding of stomach content 

      Soininen, Eeva Marjatta; Zinger, Lucie; Gielly, Ludovic; Bellemain, Eva; Bråthen, Kari Anne; Brochmann, Christian; Epp, Laura; Gusarova, Galina; Hassel, Kristian; Henden, John-André; Killengreen, Siw Turid; Rämä, Teppo; Stenøien, Hans; Yoccoz, Nigel; Ims, Rolf Anker (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Lemmings are key herbivores in many arctic food webs, and their population dynamics have major impacts on the functioning of tundra systems. However, current knowledge of lemming diet is limited, hampering evaluation of lemming–vegetation interactions. This lack of knowledge is mainly due to methodological challenges, as previously used microhistological methods result in large proportions of poorly ...
