Main goal

  • Revisit glacial survival & postglacial dispersal using metabarcoding and innovative ancient DNA (aDNA) methods, with the ultimate aim of unifying phylogeography with palaeoecology.
  • Subgoals

  • Determine if boreal trees, dwarf shrubs and arctic herbs survived the glaciation in glacial or cryptic refugia.
  • Determine dispersal routes and calculate migration rates based on palaeo-phylogeography.
  • Model future distribution and genetic diversity based on past dispersal rates and pattern of genetic diversity.
  • Resources

    We are currently processing data from over 50 locations across Europe using a reference library of assembled genome skims from over 6000 individuals through PhyloNorway, PhyloAlps, and PhyloCarpates (Alsos et al. 2020).
