Vegetation and climate changes around the Lama Lake, Taymyr Peninsula during the Late Pleistocene and Holocene reconstructed from pollen records
A continuous lacustrine sequence from the western part of Lama Lake (69°32'N, 90°12'E),completed by a peat sequence from the lake catchment provides the first detailed environmentalreconstruction for the Late Glacial and Holocene on the Taymyr Peninsula. Scarce steppe-likecommunities with...

A continuous lacustrine sequence from the western part of Lama Lake (69°32'N, 90°12'E),completed by a peat sequence from the lake catchment provides the first detailed environmentalreconstruction for the Late Glacial and Holocene on the Taymyr Peninsula. Scarce steppe-likecommunities with Artemisia, Poaceae, and Cyperaceae dominated during the Late Glacial. Tundra-like communities with Betula nana, Dryas, and Salix grew on more mesic sites. There are distinctclimatic signals, which may be correlated with the Bølling and Allerød warmings and Middle andYounger Dryas coolings. The Late Glacial/Preboreal transition, at about 10,000 14C yr BP, wascharacterized by changes from predominantly open herb communities to shrub tundra ones.
