Reprezentacja współczesnej roślinności wodnej w makroszczątkach stropowej części osadów niewielkiego płytkiego zbiornika

Abstract

The study presents results of investigations on relations between associations of carpological remains of aquatic plants preserved in the roof layer (2 cm) of deposits and the contemporary vegetation of small shallow reservoir. Carried out analy-ses of 40 samples of capacity of about 100 cm3 proved that associations of macrofossils generally well reflect the species com-position of parent phytocenoses. In deposits 60% of presently occurring species were represented. It was also stated that among many factors influencing the distribution of diaspores of aquatic plants in the environment investigated both distribution of patches of emerged vegetation and shape of its bowl are of crucial importance.
