    • Paleoeconomy more than demography determined prehistoric human impact in Arctic Norway 

      Brown, Antony; Rijal, Dilli Prasad; Heintzman, Peter D.; Clarke, Charlotte, L.; Blankholm, Hans Peter; Høeg, Helge I.; Lammers, Youri; Bråthen, Kari Anne; Edwards, M E; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-07)
      Population size has increasingly been taken as the driver of past human environmental impact worldwide, and particularly in the Arctic. However, sedimentary ancient DNA (sedaDNA), pollen and archaeological data show that over the last 12,000 years, paleoeconomy and culture determined human impacts on the terrestrial ecology of Arctic Norway. The large Mortensnes site complex (Ceavccagea ¯dgi, 70◦N) ...

    • Persistence of arctic-alpine flora during 24,000 years of environmental change in the Polar Urals. 

      Clarke, Charlotte, L.; Edwards, Mary, E.; Gielly, L; Ehrich, Dorothee; Hughes, P.D.M.; Morozova, L.M.; Haflidason, Haflidi; Mangerud, Jan; Svendsen, John-Inge; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-23)
      Plants adapted to extreme conditions can be at high risk from climate change; arctic-alpine plants, in particular, could “run out of space” as they are out-competed by expansion of woody vegetation. Mountain regions could potentially provide safe sites for arctic-alpine plants in a warmer climate, but empirical evidence is fragmentary. Here we present a 24,000-year record of species persistence based ...
