Communities of Invertebrates of the Cooling Pond of the Chernobyl Nuclear Power Station. Report 1. Communities of Zooplankton, their Composition and Structure
3-21
10.1615/HydrobJ.v42.i1.10
The structure of zooplankton communities in the cooling pond of the Chernobyl NPS was studied in 2002-2003 after its removal from service. A total of 12 communities of zooplankton differing in their composition, structure, in the complex of dominant species, and also in the quantitative indices of their development, was distinguished in the cooling pond. They included more than 50 species of invertebrates. During the period of investigations, zooplankton was represented by a larger number of species as compared to the period characterized by essential influence of heated waters on zooplankton development.

Long-term studies suggest that the communities of benthic invertebrates of the Kanev reservoir are formed according to the concept of the stage development of zoobenthos of lowland reservoirs. A total of 209 species of invertebrates was found in the benthic fauna of the reservoir. In recent 30 years the number of species of invertebrates of the Ponto-Caspian complex increased from 4 to 22. In recent 10−15 years the biomass of macrozoobenthos, with the exception of mollusks, accounted for 6−10 g/m2.

The structure of phytomicroepiliton of the Teterev river was investigated. Seasonal dynamics of algae communities occurring on stones of the studied section of the river were revealed. The Shannon index of species diversity suggests that the highest intensity of phytomicroepiliton development was registered in springtime.

The nitrate reductase activity was determined in 13 species of macrophytes. The level of this enzymatic activity may be used in conditional assessment of the contribution of these plants to the transformation of nitrate nitrogen. Direct correlation was found between nitrate reductase activity and the content of nitrate nitrogen in water.
Effect of the Ionic Form of Cadmium on Reproduction and Development of Lymnaea stagnalis L.
68-74

The effects of cadmium ions on reproduction and development of Lymnaea stagnalis L. was investigated. It is concluded that there appear stages in activity of the reproductive system of Lymnaea stagnalis under toxic influence of cadmium.

Zn2+, Mn2+, Cu2+, Pb2+(0.1, 0.12, 0.01 and 0,01 mg/L concentrations, respectively) and their mixture acted on the crayfish Astacus leptodactylus for 14 days effected in increased prooxidant processes in the hepatopancreas. An integrative index of the antioxidant-prooxidant state appeared to be a sensitive nonspecific test for the pollution of water with heavy metals.

Heavy damage of the common reed Phragmites australis (Cav.) Trin. ex. Steud. by gall-forming arthropods in water bodies within the Chernobyl NPP inner (10-km) exclusion zone were under study. Two mite species of the family Tarsonemidae, Steneotarsonemus phragmitidis (Schlechtendal, 1898) and S. gibber (Suski, 1970), were detected and identified as gall-producers. Cases of lesion of common reed caused by larvae of gall-producing fly of the family Chloropidae, the genus Lipara (Me3gen, 1830), are considered as well.

The description of a new model of sampler for obtaining zoobenthos specimens for their qualitative and quantitative analyses is presented. The proposed model is a multifunctional one and can be applied instead of similar gears. It is usable for sampling of benthic invertebrates in various microbiotopes in watercourses, such as large boulders, rocks, flooded trees, and soft grounds. Moreover, it the sampler can be used as a drift net, a scraper, and a lift net.
