Abstract

Relevance. The article examines the taxonomic composition, biogeographic features, and quantitative dynamics of planktonic crustaceans in the Papan and Nayman reservoirs of Southern Kyrgyzstan. During the study, 29 species and infraspecific forms of crustaceans were identified. Cladocera (52%) and Copepoda (41%) were found to dominate the zooplankton community. Based on the Jaccard index, the faunistic similarity between the reservoirs was determined to be low (K=0.30). Seasonal dynamics of zooplankton, the influence of hydrological regime, anthropogenic pressure, and climatic factors were analyzed. The obtained results can be used in ecological monitoring and assessment of aquatic ecosystems in the region.
