Species Composition of the Zooperiphyton of the Beshkil River (Tyumen region)

Western Siberia is covered by a network of medium and small rivers (Western Siberia, 1963). The Beshkil River belongs to the small rivers of the Tyumen region, the mouth of the river is located 87 km. on the left bank of the river Iset. Small rivers are characterized by a lower flow rate and depth. They are overgrown with higher aquatic vegetation, they heat up better, and the process of silt accumulation takes place in them more intensively (Sharapova, 2007). On most rivers and lakes in the south of the Tyumen region, studies of zooperiphyton have not been carried out; there are no data on the species composition. Data set for the river. Beshkil includes 39 species of organisms. The research was funded by RFBR and Tyumen Region, project number 20-44-720008
