Diatoms in
A. S. Stenina
Abstract
For the first time, the diatoms of different communities in Ural tributaries of the Pechora River, the Maly Patok and the Svetly Vuktyl were studied. As a total, 190 species with varieties and forms from 34 genera and 13 families were found. Comparative analysis of diatoms in the rivers on undisturbed territory and on the territory with man-made changed was made. Differences in taxonomical, cenotical, ecological and geographical structures of diatom complexes in the rivers studied were revealed. The main factors determining them are natural peculiarities (course, pH, conductivity) and weak anthropogenic influence.
