The method used was random sampling of individuals from transects laid out between the upper and the lower population area limits on sand biochores of the phytocoenoses of two plant communities. The changes of all biometric characteristics were found to be directional. They depended among other things on the increasing organic matter content in the sediment, but were not related to the kind of lake or plant community.
