    • Ancient DNA, Lipid Biomarkers and Palaeoecological Evidence Reveals Construction and Life on early Medieval Lake Settlements 

      Brown, Antony; van Hardenbroek, Maarten; Fonville, Thierry; Davies, Kimberley L.; Mackay, Helen; Murray, E; Head, Katie; Barratt, Phil; McCormick, F; Ficetola, Fransesco Gentil; Henderson, Andrew; Crone, Anne; Cavers, G; Langdon, Peter G.; Whitehouse, Nicki J.; Pirrie, Duncan; Alsos, Inger Greve; Gielly, L (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-03)
      Direct evidence of ancient human occupation is typically established through archaeological excavation. Excavations are costly and destructive, and practically impossible in some lake and wetland environments. We present here an alternative approach, providing direct evidence from lake sediments using DNA metabarcoding, steroid lipid biomarkers (bile acids) and from traditional environmental analyses. ...

    • 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 ...
