On the Taymyr Peninsula and Severnaya Zemlya Archipelago, Central Siberia, a joint German/Russian multidisciplinary research project focuses on the Late Quaternary history of climate and environment. Within the scope of this project, palynological studies were carried out on a 10.8-m core from Lama Lake, situated in the south-west of the research area. The core, which did not reach the base of the lacustrine sediments, reveals the vegetation and climate history of the last 17 000 years and demonstrates that this area was not glaciated during that time. The Pleistocene/Holocene transition is, as elsewhere in the northern hemisphere, characterized by increased temperatures during the Bølling, Allerød and Preboreal with interruptions during the Older (post-Bølling) and Younger Dryas events. The Holocene climate optimum at Lama Lake probably occurred within the Boreal period, when dense larch forests developed. The Atlantic period was characterized by warm conditions that favoured the establishment of ... : Supplement to: Hahne, Jürgen; Melles, Martin (1997): Late and postglacial vegetation and climate history of the south-western Taymyr Peninsula (Central Siberia), as revealed by pollen analysis of sediments from Lama Lake.
