Late Holocene changes in vegetation and atmospheric circulation at Lake Uddelermeer (The Netherlands) reconstructed using lipid biomarkers and compound-specific δD analysis

We reconstructed middle to late Holocene changes in atmospheric circulation patterns and vegetation in north-west Europe by applying novel geochemical techniques to the sediment record of Lake Uddelermeer (The Netherlands). A comparison of higher plant-derived leaf wax n-alkane distributions archived in the lake sediments with those in living plant material, combined with palynological analysis, indicates that the vegetation immediately surrounding the lake became more open at 3150 cal a BP, while the regional vegetation responded more gradually and ∼650 years later. Our record of the hydrogen... Mehr ...
