The taxonomical composition and number of life forms of macrobenthos assemblages were described for 82 streams in the Central Part of European Russia. The data (445 qualitative samples) were taken from the bottom and macrophytes. The communities typical for four main types of substratum (stones, macrophytes, sand and mud) differ at the level of species,(More)
Based on original data (450 samples from 115 streams of European Russian middle latitudes—from Pskov to Kostroma regions), an attempt is made to describe the diversity of rheophilic communities inhabiting stream bottoms and macrophytes. A total of 39 community types are identified by the Braun-Blanquet method. Their taxonomical and structural(More)
The invertebrate fauna of rivers and streams of the Southern Yamal has been studied using original specimens (122 bottom and vegetation samples). A total of 158 taxa have been recorded, many of which are new for this region. Among them, 18 types of rheophilic macrobenthic communities have been distinguished which mainly correspond to certain types of(More)
The relationship between the abundance of taxa and life forms of lithorheophile macrobenthos and its variability were studied based on 200 quantitative samples from six territories of the Palaearctic (Moscow province, northwestern Caucasus, eastern Carpathians, northern Karelia, South Urals, and Altai mountains). The set of taxa predominant in the(More)
Spatial differentiation of the Eurasian freshwater faunas is analyzed based on the original and published data on the aquatic insects, crustaceans, and mollusks (about 8800 species in total). The Hacker-Dice similarity index is employed as a principal criterion of differentiation. The schemes of biogeographic zonation are constructed for the nine large(More)
It is suggested that the eastern Novosibirsk region appeared as a margin between the Western and the Eastern Palaearctic zones in regard to the faunas of stream communities of rheophilic invertebrates. The western (European) elements of the fauna prevail in the lowland areas; but both faunas, eastern and western, combine at Salairsky Ridge. In addition,(More)
Spatial distribution (SD) of White Sea intertidal soft-bottom communities was studied at scales from decimetres to dozens of kilometres on the basis of an extensive dataset (464 samples of macrofauna, 349 samples of ciliates, and 333 samples of diatoms). We used the information index of structural heterogeneity D(I) (Azovsky et al., 2000 // Mar. Biol. 136(More)
The fauna and diversity of macrozoobenthos communities in watercourses of the Khibiny tundras, the surrounding plains, and the Kandalaksha Coast of the White Sea (Murmansk oblast) are described from materials collected by the authors. A checklist of 110 recorded taxa is given, with larvae of Diptera, Trichoptera, Ephemeroptera, and Plecoptera prevailing. A(More)
The distribution of lithorheophil macrobenthos was studied in the range of scales from decimeter (regions in the scope of one stone) up to seven kilometers on the basis of 153 quantitative samples from oligosaprobic stream in Moscow region. Community shows significant spatial heterogeneity even at the small scale: life forms inhabit different sides of each(More)
The species composition and communities of soft-bottom macrozoobenthos of the eastern Black Sea coast have been described based on an original collection of 132 quantitative and over 700 qualitative samples. More than 150 species and supraspecific taxa have been registered; 10 types of communities, each having a specific complex of dominants, have been(More)
