Holocene climatic events linked to environmental changes at Lake Komoany Basin, Czech Republic

Former Lake Komoany, located in Northwest Bohemia in Central Europe, provides multiple proxies (pollen, plant macrofossils, diatoms, chironomids and sediment chemistry) that allowed reconstruction of the development of its aquatic environment and catchment, throughout the Holocene. In order to reconstruct the climatic forcing of this development, we performed a pollen-based reconstruction of climate changes using the best modern analogue method. The climate reconstruction was successful for the interval of 10.0-3.2ka BP. We demonstrate that shifts in climate were coupled with biotic changes within the lacustrine environment. Both processes were interconnected mainly through changes in the water level status of the lake. The most significant climatic and environmental changes were recorded at 9.1, 6.3, 4.8/4.7, 3.8 and 3.5ka BP.
