Mollusks as indicators of the state of soil and water in Uzbekistan

The work examines the vital activity of mollusks. About 160 species of terrestrial mollusks have been identified in Uzbekistan. It has been established that 12 species of terrestrial mollusks live on the plains in the steppe serozem soils at heights. Psychromezobionts live in hydromorphic soil among turf and under stones. Typical and dark soils are home to over 20 species of mollusks. On brown, brown-mountain-forest, light-brown meadow-steppe soils, 4 species of endemic mollusks live. Brackish-water mollusks were also found, which are divided into eurygane, living in a wide range of water salinity, and stenohaline, living in a narrow range of water salinity. Mollusks-indicators of the type and condition of the soil have been determined. In conclusion, the author concludes that it is necessary to further study the species composition and indicator role of mollusks in Uzbekistan.
