Abstract

The data on the species diversity of representatives of the genus Teilingia Bourrelly are summarized. from the water bodies of Western Siberia, their distribution by zones and subzones. To date, 4 species and intraspecific taxa from the order Desmidiales are known for the region. Representatives of this family are found mosaically throughout the entire territory of Western Siberia. The largest number of taxa (3) was found in the middle taiga, in the tundra – two species. No species were found in the Irtysh floodplain, forest tundra, northern taiga, forest-steppe and steppe zones. In watercourses, including the Ob and Irtysh, as well as in lakes of different types, 3 taxa were identified, respectively. One species was found in swamps and in temporary reservoirs.

Highlights

The genus Teilingia Bourrelly it was described by the French phycologist P
This paper presents the results of the distribution of Teilingia in various zones of the territory of Western Siberia within the borders of the Russian Federation and their ecological characteristics
After conducting original research in the Siberian Uvals Nature Park, located in the middle taiga subzone, one species was identified: Teilingia wallichii. This species was vegetated in oxbow lakes in the vicinity of the base "Deep Sabun" noted at a temperature range of 18 to 19 ° C and at a transparency of 0.23 to 0.30 m

Summary

Introduction

The genus Teilingia Bourrelly it was described by the French phycologist P. It includes some of the species previously assigned to the genus Sphaerozosma. The species of this genus are distinguished from other genera of the order Desmidiales (family Desmidiaceae) by a peculiar cell structure. The cells are connected in single-row long threads by means of 4 apical outgrowths. The threads are free-floating, smooth or slightly twisted, surrounded by mucus. The cell wall is smooth or covered with a few granules. With insufficient knowledge of the species diversity of this genus on different continents, information on ecology and distribution is extremely important
