Abstract
The algae composition of Euglenophyta division of the steppe river Karasuk has been studied. 94 species, 27 varieties and forms from 16 genera, 5 families, 2 orders and 1 class have been found. Zonal peculiarities of the taxonomic structure of the division, have been noted, the distribution pattern of euglenophytes across ecotopes is shown, their role in the phytoplankton numbers and biomass has been estimated, and attachment of species of this division to sites of the river with an increased biotic contamination has been established.
