Statistical analysis of the freshwater mussels in the river Bolshoi Kinel and factors determines its

The results of analysis freshwater mussels of the river Bolshoi Kinel. Number of «hidden» species evaluated statistically. Is it shown the necessary minimum sampling effort to identify the allegedly full reservoir species richness. The taxonomical structure of mussels taxocene closeness in the architectonics along with the wide variability extent. Determining factors in the development and distribution of mollusks are flow velocity, transparency and water temperature.
