title: Species composition in assemblages of the family Unionidae Rafinesque, 1820 (Mollusca: Bivalvia) as an indicator of ecological changes in water bodies of Central Polissia, Ukraine
abstract: Though Ukraine is one of the countries with insufficient water supply, the northern region of central Polissia has a dense river network. The region’s major rivers – Teteriv, Sluch, Ubort, and Uzh – have undergone significant anthropogenic change.
