Species diversity and quantitative indicators of zoobenthos in the Glubokoe lake system (Kazan)

The results of a study of the composition and quantitative structure of zoobenthos in lakes Bolshoye and Maloye Glubokoe (Kazan, Lebyazhye city forest park) are presented. In total, 55 species of invertebrate were found in the lakes, including the oligochaete worms Ripistes parasita , Vejdovskyella comata and the larvae of midges Probezzia seminigra , previously not recorded in the fauna of Tatarstan. Macrozoobenthos in both lakes is represented mainly by communities dominated by oligochaetes Naidinae and Tubificinae.
