There are 70 species and forms in the composition of zoobenthos of the river Ural and in water bodies of its floodplain have been identified. Mayflies and chironomids are represented in various ways (13 and 12 species and forms, respectively). Caddisflies (10) and stone flies (7) are rich in species. Among other invertebrates, bivalves (6) and gastropods (5), small-bristled worms (5), non-chironomid dipterans (4), leeches, crustaceans and dragonflies, bugs and beetles were recorded. On sandy-gravel-pebble soils is formed a zoobenthocenosis, dominated by the mayflies Ephoron virgo. They are accompanied by Chironomidae larvae. The biomass of the community varies between of 29.32–31.68 g/m2 with an abundance of 18.1–32.44 thousand ind./m2. In the coastal of the channel is formed a pelophilic zoobenthocenosis, the basis of it abundance and biomass are constituted by the small-bristle worms Limnodrilus hoffmeisteri. They are accompanied by mollusks Stagnicola palustris and mysids P. lacustris. The biomass of the pelophilic community is 13.68 g/m2 with a population of 15.45 thousand ind./m2. In floodplain water bodies are formed pelophilic zoobenthocenoses, the biomass of which varies in the range of 19.2–34.24 g/m2 with an abundance of 5.64–30.04 thousand ind./m2. Chironomid larvae constitute the base of the population. The biomass is composed by dragonflies Libellula sp., Chironomids, and mollusks Bithynia tentaculata.

The first data about the algae flora of the water bodies of the “Aschisayskaya Steppe” plot of the State Nature Reserve “Orenburgsky” are presented. 217 species and intraspecies taxa of microalgae belonging to the phyla Chlorophyta, Euglenozoa, Bacillariophyta, Ochrophyta, Streptophyta, Miozoa and Cyanobacteria were found in five reservoirs of the plot. New species for the territory of the Orenburg Region, as well as rare species for Russia are noted, their characteristics and micrographs are given. The obtained data expands the current understanding of the range of the identified taxa.

There is analysis of the taxonomic diversity of Rotifers, Copepods, and Cladocerans from water bodies, located on the territory of clusters of the Ubsunurskaya Kotlovina State Natural Biosphere Reserve, located within the Russian part of the Ubsunur Basin, on the border with Mongolia. A total of 87 species from 53 genera, 22 families, 10 orders were recorded. Cladocerans include 40%, Copepods – 37% and Rotifers – 23%. The dependence of species diversity on the level of mineralization was established – 89% were found in fresh water bodies, in salty – 23%, in brackish – 14%. Zooplankton composition of the Lake Tore-Khol has undergone some changes in comparison with the data of the second half of the last century. The zooplankton contains species of crustaceans that are rare for the Rossian fauna – Apocyclops dengizicus, Eucyclops dumonti, Alona flossneri. Tuva is the northernmost point of A. dengizicus in Russia – its habitat, lake Amdaigyn-Khol, located at 530 parallel. The spring Bulak is polluted by mechanized water intake for technical needs, which is confirmed by the appearance of an indicator of this process – Brachionus nilsoni, which then enters the lake Shara-Nur. Location on the shore of the lake Tore-Khol camp site led to the development of Filinia longiseta, which had not previously been observed in large numbers. In general, the presence of rare species for the fauna of Russia in the water bodies of the reserve indicates the presence of favorable conditions for their development and life.
