    • Metabarcoding as a quantitative tool for estimating biodiversity and relative biomass of marine zooplankton 

      Ershova, Elizaveta; Wangensteen, Owen S.; Descoteaux, Raphaelle; Barth-Jensen, Coralie Marie Christine; Præbel, Kim (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-31)
      Although metabarcoding is a well-established tool for describing diversity of pelagic communities, its quantitative value is still controversial, with poor correlations previously reported between organism abundance/biomass and sequence reads. In this study, we explored an enhanced quantitative approach by metabarcoding whole zooplankton communities using a highly degenerate primer set for the ...

    • Origin of marine invertebrate larvae on an Arctic inflow shelf 

      Descoteaux, Raphaelle; Huserbråten, Mats Brockstedt Olsen; Jørgensen, Lis Lindal; Renaud, Paul Eric; Ingvaldsen, Randi Brunvær; Ershova, Elizaveta; Bluhm, Bodil (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-20)
      Many benthic invertebrate taxa possess planktonic early life stages which drift with water currents and contribute to dispersal of the species, sometimes reaching areas beyond the current ranges of the adults. Until recently, it had been difficult to identify planktonic larvae to species level due to lack of distinguishing features, preventing detection of expatriate species. Here, we used DNA ...
