POSTGLACIAL CLIMATIC FLUCTUATIONS AND PLANT COVER TRANSFORMATION IN THE NORTH KANIN REGION INFERRED FROM MARINE POLLEN DATA
Summarizing the results of palynological investigation of the Northern Kanin bottom sediment sequence we distinguish five pollen zones corresponding to major steps of Kanin Peninsula plant cover transformation during the Postglacial caused by significant global climate fluctuations. They are: i) gradual supplanting of the Early Holocene arctic-type periglacial treeless vegetation by tree-like birch and pine light-forests due to Boreal climate warming; ii) postdated northern advance of the dark-needled taiga boundary during Atlantic optimum; iii) tundra environment revival in response to Late Holocene climate deterioration
