FAUNA AND ECOLOGY OF MOLLUSKS OF THE FAMILIES UNIONIDAE, CORBICULIDA, AND LYMNAEIDAE COMMON IN AQUATIC ECOSYSTEMS OF THE AKDARYA RIVER
The primary objective of this study was to investigate the fauna and ecology of mollusks of the families Unionidae, Corbiculidae,
and Lymnaeidae common in the aquatic ecosystems of the Akdarya River. Increased dry periods lead to a decrease in
biodiversity in natural water bodies and changes in aquatic ecosystems. The distribution of 15 mollusks species and one
subspecies in the Akdarya River was studied. Twelve species were found in the Akdarya region near the town of Chelak, and 13
species were found in the lower reaches of the Akdarya Reservoir. When analyzing the ecological groups of mollusks common in
the Akdarya River biotopes based on their habitats, the presence of pelorheophiles, pelorymnophiles, rheophiles, phytophiles,
telmotophiles, and phytoreophiles was studied.
