PHYTOCOENOTIC ROLE OF ZYGNEMATALES IN THE WEST SIBERIAN PLAIN // Tomsk State Pedagogical University Bulletin. 2013. Issue 8 (136). P. 35-42

In 2006–2011 in water bodies of the tundra, forest tundra, forest and forest steppe belts of the West Siberian Plain, the species and coenotic composition of the hydrophilic coenoses involving 15 Zygnematales species were studied. The Zygnematales species were found to form seasonal synusiae and be a dynamic component of aquatic macrophyte vegetation of the region.

VEGETATION COVER OF WATER OBJECTS OF THE UY RIVER VALLEY (OMSK REGION) // Tomsk State Pedagogical University Bulletin. 2013. Issue 8 (136). P. 48-54

The article presents a short description of the water objects of exploring territories. The majority of explored lakes are the old bed areas of the Uy River. The main body of the article is devoted to the exploration results of the flora and cenotic composition of vegetation cover of the Uy River Valley water objects. According to the data of geobotanic descriptions the list of water macrophytes groupings types for the Uy River Valley water objects was done. 17 out of 27 described associations of hydramacrophytes are cited for the territory of exploration the first time.
