ABSTRACT. In the frame of our work, a special large-scale study on diversity of the Cladocera (Crustacea: Branchiopoda) in small water bodies of Moscow city was carried out for the first time. Forty five species belonging to 23 genera were found in 112 water bodies. Eurythopic species, which are widely distributed in Russia and neighboring areas, predominate there. Scanning electron microscope images are provided for some taxa to confirm their accurate identification. The investigated water bodies are characterized by an oligodominant species complex, which includes only two taxa (Chydorus sphaericus and Bosmina longirostris). Our analysis of the mutual associations of the species at a significance level of p = 0.05 using the binomial distribution model revealed four major clusters. The cluster 1, containing many species of different mode of life and taxonomic position, is present in many water bodies. Its existence revealed a significant similarity between the species composition of most studied samples, independently of the water body type and size. Such uniformity seems to be a sign of the urban territories. The chydorid cluster 2 was confined to water bodies that can be characterized as mesotrophic, with a moderate anthropogenic pressure. Moreover, two daphniid-dominated clusters (3 and 4) were revealed. Presence of a local mutual association 3 containing Daphnia curvirostris, D. magna, Ceriodaphnia laticaudata and C. quadrangula indicates a high level of eutrophicationin a water body.
