Abstract

Investigations on algae in the Serbian part of the Tisa river, in a distance from 79.5th to 64th km during 1997, showed the presence of the species Didymosphenia geminata (Lyngb.) M. Schmidt (Bacillariophyta) in all phytoplankton samples and partly in the phytobenthos. According to detailed morphological characteristics, D. geminata belongs to the morphotype geminata (sensu Metzeltin et Lange-Bertalot). The findings of D. geminata in the investigated part of the Tisa river, refute current literature data on the species ecology and distribution.
