Pulmonary limacons (Pulmonata cuvier, 1817) as indicators of water quality in the rivers of Southern Ural (the Republic of Bashkortostan)

Here we consider the possibility of using gastropods to increase the importance of bioindication research on the course of ecological monitoring of the rivers of the Southern Urals. We studies gastropods collected from 2005 to 2016 in 17 State Water Posts in the Southern Urals. A total of 27 species of pulmonary snails were identified. A list of permanent, additional and accidental species of gastropods is reported for the first time for the region. Statistically significant correlations between the list of gastropods and several hydrochemical indices have been revealed. Regression models were constructed to predict the list of species, depending on the concentration of pollutants in river waters.
