The American rotifer Kellicottia bostoniensis (Rousselet, 1908) was first recorded in the Kama Reservoir (Kama River, Middle Volga basin) in 2012. The species was found in over 70% of the samples; its maximum abundance was 2000 ind./m³. This alien species co-existed with closely related native species K. longispina (Kellicott). This is the easternmost location (56°–57° E) for K. bostoniensis in the Volga River basin and in Europe.
Interannual variations in species richness and quantitative parameters of macrozoobenthos in floodplain lakes of the Khoper Nature Reserve have been studied to reveal their dependence on flood regime and overgrowth by macrophytes. It has been shown that a particular species richness of macrozoobenthos is preserved for several years. Interannual variations in characteristics of lakes, particularly in the flood period, determine the changes in quantitative parameters of macrozoobenthos. The overgrowth rate of lakes by macrophytes does not exert an effect on species richness and quantitative parameters of macrozoobenthos, but determines its saprobiological structure. The flood period necessary for the formation of the most abundant communities of macrozoobenthos in the studied lakes is 30 days. Nevertheless, this is not the main factor determining its quantity in lakes constantly connected with the river by a channel. It is confirmed that drying or a sharp drop in water content of the river play the role of a trapping point and triggers ecosystem transformations in small water bodies.
The fauna of water beetles in coastal areas of the Bolshezemelskaya Tundra and on the Vaygach and Dolgiy islands, Pechora Sea, comprises a total of 42 recorded species; in local faunas, the number of species decreases northward from 19–26 in southern mainland tundra to nine in typical tundra of the Vaygach Island. The faunal similarity between pairs of areas is 21%–52% (39%–52% between mainland areas). The family Haliplidae is represented by three species, Dytiscidae – 32 species, Helophoridae – four species, Hydrophilidae – two species and Hydraenidae – one species. Most of the species have large ranges both longitudinally and latitudinally. Cryophile species are rather few (five species, 12%). There are clear differences between the beetle assemblages of weakly brackish lakes marshes and waterbodies of the bedrock coast. The strongest preferences for particular habitats have been revealed in species associated with sand substrates in waterbodies or with the floodplain of a large river. The male genitalia and male protarsal claws of Agabus luteaster (Zaitzev, 1906), recently recorded as new to Europe, are illustrated for the first time as well as Ochthebius kaninensis Poppius, 1909.
As active filterers and sedimentators, mollusks Viviparus contectus (Millet) clear water from suspensions in the Tnya River. The sedimentation ability of mollusks is assessed on the basis of experimental studies at three stations using the funneling technique. Mollusks at the age of 3 and 5 years are used. The rate of sedimentation of V. contectus is 7.3 to 13.7 mg/(spec. day) in July 2014. The efficiency of suspended sedimentation is higher in younger individuals. The rate of sedimentation is determined by the total body weight of mollusks; the ratio between these parameters is described by the exponential function. V. contectus contributes to the decrease in the content of organic matter in the water with a rate of 0.055 to 0.069 mg of O2/(dm³ spec. h), as well as to the enrichment of the near-bottom water layer with organic matter.
This paper presents an annotated list of nematode taxa found in the course of investigations of meiobenthic communities in various freshwater bodies in central and southern Vietnam. Data on the structure and abundance of populations, ecology, and global and local distribution are given along with taxonomic and other comments. The occurrence and level of taxonomic richness of roundworms in the studied bodies of water and biotopes are discussed briefly. In total, 127 taxa of 10 orders and 38 families of nematodes are listed. The number of recorded genera is 60; 72 representatives of these genera are identified to species level. The listing includes 48 taxa that had not been previously recorded from Vietnamese territory and 17 species originally collected, analyzed, and described as new to science from this country. The results of these investigations and an overview of the previously published data indicate that taxonomic composition and diversity of Nematoda in Vietnamese freshwater habitats remain poorly studied, except for certain areas.
