First record of freshwater bryozoa Plumatella emarginata Allman, 1844 (Phylactolaemata) in the aquatic invertebrate fauna in the Kurchatov reservoir

In new for the biosphere, techno-ecosystems, the marginal, contour or marginal biotopes and their population i.e. the biocenoses that live here, often play a determining role for the whole ecosystem and a man. Important for these ecosystems are ecotopic groupings (benthos and periphyton), their heterotrophic component and according to the hydrobiological classification - zoobenthos and zooperiphyton. The studying of these groups was caused by their significant role in the life activity of hydroecosystems as well as by the problems associated with the biological disturbances they cause. To date, there are certain difficulties in the taxonomic identification of benthos and periphyton organisms in general and freshwater bryozoans in particular. It is necessary to take into account the specificity of technical elements that can determine peculiar characteristics of the entire techno-ecosystem. In this sense, the surface of hydroconstructions is quite similar to natural solid substrates...
