Abstract:
Ecotone
zones are very interesting objects for the investigations of the ecological
succession of plant communities. The main aim of the present study was to
analyse the rate and direction of changes in ecotone vegetation caused by
changes in a level of groundwater table. In the studies carried out during
years 1993–1998 a generally accepted method of a belt transect was applied.
Transect 5 m wide ran across all aquatic, litoral and land phytocenoses. Most
visible changes took place in the aquatic and littoral phytocenoses. Some of
them disappeared and then reconstructed themselves within a new range, in
others the species composition was changed. |
