- Abstract
Results of a detailed investigation into the qualitative composition of the desmid flora of the river Tisa, performed from April 2002 to May 2003, are presentet in this paper. A total of 33 desmid taxa belonging to genera Closterium, Cosmarium and Staurastrum were recorded from which 12 taxa are new to the Vojvodina stretch of the river Tisa, whereas Cosmarium subcostatum var beckii and C. vexatum var. rotundatum are new to the algal flora of Serbia. Qualitative dominance of desmid taxa, typical of alkaline and eutrophic ecosystems, was observed. The qualitative and partly relative quantitative composition of planktonic taxa were analysed dependent on the physicochemical characteristics of the water. Basised on the presence of desmids, which are bioindicators, water quality was analyzed. Despite the inconvenient environmental conditions, special ecological remarks regarding partly unexpected presence of Cosmarium subcostatum and C. subcostatum var beckii as inhabitants of oligotrophic lakes and pools from a boreal part of Northwestern Europe were also recorded. An almost regular seasonal dynamics of the desmid community of the river Tisa was observed during one-year study.
