Abstract
The Late-glacial and Postglacial sediments of the former Komořany Lake in North-West Bohemia were studied by means of diatom analysis to trace the pattern of past environmental change in the lake. Several phases of lake development could be distinguished.
Originally the Komořany Lake was a eutrophic shallow water basin. The diatom succession in the early Postglacial sediment indicates alternating alkaliphilic, epiphytic and planktonic diatom communities associated with changes in water level in the basin. At the beginning of the Subatlantic period the water level began to rise and the development of planktonic diatoms, typical of small eutrophic lakes, occurred.
Later, the basin became shallow again and the number of indifferent and acidophilous diatoms increased. This is typical for the final phase of the infilling process of a lake before its transformation to peatland
