【 摘 要 】

The Baryczka stream is a small (about 20 km long), left bank tributary of the River San (Podkarpackie Voivodeship). Studies on diversity of diatom communities using OMNIDIA software were conducted in 2010 and 2011. Diatomaceous indices IPS, GDI and TDI and Van Dam et al. classification system were used for water quality assessment. Planothidium lanceolatum, Cocconeis placentula var. lineata, Achnanthidium minutissimum var. minutissimum, Nitzschia linearis, Rhoicosphenia abbreviata, Navicula lanceolata and Naicula gregaria were the most numerous. Values of the IPS index indicate good water quality (II–III class). Based on the GDI index, waters of the Baryczka stream were classified to III class water quality. The TDI index indicated poor and bad ecological state on the most sampling sites. On all sampling sites alaliphilous (pH>7) diatoms taxa predominated. The most common were eutraphentic and hypereutraphentic diatoms. With respect to trophy, it was shown that α- and β-mesosaprobous diatoms were the most common (III and II class water quality).
