摘要

本文对第聂伯河储层中Cumacea目甲壳类动物的分布进行了分析。据认为，这些甲壳类动物可能会与引入的甲壳类动物、甲壳类动物和软体动物一起进入新形成的储层。在第聂伯河梯级的所有水库中，除了基辅水库(迄今为止尚未发现)，已登记的Cumacea有4-5种。pectinata (Pterocuma pectinata, Sow.)在其发育的定量指标上占主导地位。调查期间，Cumacea的数量和生物量分别为25 ~ 131株/m2和0.06 ~ 0.13 g/m2。在2 ~ 7 m深度的砂土和淤积砂土上，Cumacea发育的定量指标最高。

Cumacea (Crustacea) in the Dnieper River and Its Reservoirs: Species Composition, Invasions, and Ecology

The spread of crustaceans of the order Cumacea in the Dnieper reservoirs is analyzed in the paper. It is thought that these crustaceans could get into the newly formed reservoirs along with the introduced Gammaridae, Mysidae, and Mollusca. In all reservoirs of the Dnieper cascade, except for the Kyiv Reservoir, where they have not been found till now, 4-5 species of Cumacea have been registered. Pterocuma pectinata (Sow.) dominates in terms of the quantitative indices of its development. During the period of investigations, the numbers and biomass of Cumacea accounted for respectively 25-131 specimens/m2 and 0.06-0.13 g/m2. The highest quantitative indices of Cumacea development were observed at the depths of 2-7 m on sands and silted sands.

期刊介绍： This journal contains translations from the premier Russian and Eastern European periodicals in aquatic biology and aquatic ecosystems, supplemented by original articles from elsewhere. The journal publishes in the area of physiology, biochemistry, systematics, ecology and conservation of freshwater fish, invertebrates, vascular plants, zoo- and phytoplankton, as well as freshwater quality and toxicology. While most of the papers deal with inland waters, the journal also publishes articles reporting on expeditionary work, especially the Antarctic and tropical seas. Hydrobiological Journal is valuable to freshwater and marine biologists and chemists, limnologists, environmental scientists, oceanographers, and toxicologists.
