MATERIAL TO THE FAUNA AND ECOLOGY OF ROTIFERS IN THE URALS. THE FAMILY BRACHIONIDAE (ROTIFERA, EUROTATORIA, PLOIMA). THE GENERA KELLICOTTIA, PLATIONUS, PLATYIAS

摘要

Information on the distribution in the Urals of the rotifer genera Kellicottia, Plationus and Platyias, family Brachionidae, is summarized based on the author's research and an analysis of the literature sources. Data on their localities, biology and quantitative development in the Urals' waters are presented. In total, seven genera of Brachionidae comprising 33 species are known to occur in this region of Russia. Kellicottia longispina (Kellicott 1879) is the most common species in the Urals, while the other two genera are rare and little-known because of their habitats being poorly prospected. Some more species of Brachionidae reported from the adjacent regions can be expected to occurd in the Urals due to climate change.
