Faunistic Composition And Zoogeographical Analysis Of Passenged Molluscs (Mollusca: Gastropoda, Pulmonata) Of Some Cities Of Uzbekistan

Abstract

As a result of the study, in the studied territories, 26 species of terrestrial and 10 species of aquatic gastropods were found. For the first time, four biotopes of molluscs have been identified on the territory of cities, among them parks and arboreal communities are the richest in terms of the number of mollusс species. Considering the limited number of reservoirs in cities, and depending on the water bodies, the malacofauna were divided into 3 groups. The frequency of occurrence and density of molluscs in water bodies of cities has been studied. According to the zoogeographic analysis, the urban terrestrial malacofauna species belong to the following species: Central Asia, Holarctic, Palaearctic, Europe, Western Asia and mountainous Asia. Aquatic malacofauna species: Western Asia, Central Asia, Palaearctic, Europe and Siberia and the Mediterranean Sea.
