The aquatic microecosystems and their environment have been studied in 12 mineral springs, located in Cis-Baikal depression and in the basin of the upper reaches of the Lena River (East Siberia). The hydrochemical characteristics of the springs, flowing from the Cambrian salt deposits are given. Their total mineralization varies from 1.1 to 123.0 g/l, water is sodium chloride. Soils, which are formed under influence of mineral waters (“parasoils”), are described. The data on the composition and quantitative abundance of aquatic fauna are presented. Six types of macroinvertebrate communities are described. The communities with domination by Turbellaria, Gastropoda and Psychodidae are recorded in weakly mineralized waters (< 3 g/l). The communities with domination by Chironomidae are found in waters with low and high (up to 28 g/l) salinity. In springs with salinity 2.5–11 g/l communities with the dominance and high biomass of amphipods Gammarus lacustris Sars are formed. A unique type of the community with the dominance by Ephydridae larvae (>97% of the biomass) is described for concentrated brines in Ust-Kut spring. Halophilic species of crustaceans are recorded in the meiofauna. The presence of marine organisms – Foraminifera, in the two springs is of special interest.

Keywords: Baikal region, mineral springs, hydrochemical composition, invertebrate fauna, zoobenthos communities.

For the first time the flora of algae and aquatic lichens is investigated in the mineral sodium chloride springs in the Northern Baikal region, flowing from the salt beds of the lower Cambrian. The full list of algae found in six springs is given. Total of 257 lower taxa from six divisions: Cyanoprokaryota (=Cyanophyta), Euglenophyta, Bacillariophyta, Xanthophyta, Chlorophyta and Streptophyta are identified. The flora of diatoms is the richest (196 taxa or 76%). The similarity of algoflora of different springs is negligible. Species which are indifferent to salinity prevail in most springs; mesohaline species dominate in the Ust-Kut spring. Among diatoms 19 taxa of halophiles are identified. The marine species Percursaria percursa (Chlorophyta) was recorded in Klyuchevskoy and Ust-Kut springs. In three springs seven species of lichens from 4 genera are identified, five species are truly aquatic and two species are capable of withstanding flooding; all species are found in freshwater ponds and streams. Two species of the genus Bagliettoa in the Baikal region are, probably, relict.

Keywords: Baikal region, mineral springs, algae, lichens, species composition, halotolerance, similarity of communities.

The study of phytoplankton from waterbodies and watercourses in the Yarayakha and Naduiyakha river basins (The Yamal Peninsula) has revealed a wide morphological variability of quantitative diagnostic features in Parlibellus crucicula: valve length and width, number of striae and areolae in 10 mm, stria density in the middle part of the valve. A number of features (raphe structure, presence of pseudosepta and obliquely oriented oval areolae) typical for the genus Prestauroneis have been found in Parlibellus crucicula that makes it possible to transfer this species to the genus Prestauroneis forming a new combination – Prestauroneis crucicula (W. Smith) Genkal et Yarushina comb. nov.

Dynamics of the species structure of Cladocera in two lakes for three- and six-thousand-year periods is studied on the materials on bottom sediments. The community of one of the lakes is in the state of a dynamic climax, and the community of the other lake is in the process of directional succession. It is shown that the species structure of both communities is well approximated by the equation of Motomura–Whittaker (model of a geometrical series). For each of the studied lakes the main parameter of this model (the coefficient of geometrical progression) on the average does not differ significantly from the theoretically derived value, equal to 1 – exp (–1) = 0.632. There is a stable relationship between species diversity of the community, the rate of ecological succession and the coefficient of geometrical progression.

Keywords: geometrical series, model of Motomura–Whittaker, succession rate, species diversity, Cladocera.

The composition of bottom invertebrates of rocky rapids and riffles in rivers of White, Barents and Baltic Seas in Eastern Fennoscandia is presented and analyzed. We identified 114 species (137 taxa of different ranks). Most of them are Euro-Siberian (44%) and Palaearctic (36%) in distribution. In species respect among functional groups collector-gatherers and collector-filterers were on the first positions. Differences in the composition of zoobenthos between the southern and northern parts of the region can be explained by latitudinal zoning, not by the genesis of fauna.

Keywords: fauna, bottom communities, functional groups, Fennoscandia, distribution.

Molluscs Viviparus contectus (Millet) are active filterers and sedimentators, they clear water in the Tnya River from the suspension. The sedimentation rate is 7.3–13.7 mg/specimen per twenty four hours in July 2014. Juvenile specimens are characterized by the highest efficiency of sedimentation. The sedimentation rate is closely related to the body mass, the ratio of these parameters is described by the power function. V. contectus promotes the decrease in the content of organic matter in water at the rate 0.055–0.069 mg O2 /(dm 3 · ind. · h) and enrichment of the benthic water layer with it.

Keywords: the Tnya River, Viviparus contectus, sedimentation, body weight, organic matter.

It is found that during 30 years of intensive walleye fishing in the Japan Sea and Okhotsk Sea of the average number of vertebrae in the caudal section has increased significantly. The maximum frequency of multi-vertebrae phenotype (33 caudal vertebrae) increased from 3–5% to 76–78%. The number and frequency of occurrence of abdominal vertebrae did not change. Experimental testing of walleye pollock sample on resistance to flow proves that the number of vertebrae in the caudal section is an important adaptive feature and observed changes of population’s phenotypic structure are the result of intensive fishing.

Keywords: Walleye Pollock Theragra chalcogramma, Japan Sea, Okhotsk Sea, fishing, phenotype, number of vertebrae, swimming ability.

Fish fry aggregation density was found to be higher in the reservoir’s open shallows adjacent to heron colony during the period of nesting. Fry of roach Rutilus rutilus L., one of the dominating species in terms of abundance was shown to possess significantly higher values of linear-weight indices and higher growth rate in the open shallows adjacent to birds’ colony. Phenotypic differences in various biotopic assemblages of fish fry were found to be dependent of habitat. It was found that edifying effect of heron colony upon fish population is of temporal character limited by the period of nesting.

Keywords: fish fry, distribution, growth, morphology, bird colonies.

Morphological Сharacteristics of the Rudd Scardinius erythrophthalmus (Linnaeus) from Small Waterbodies of the Upper Volga and Оka Basins.

For the first time, this paper gives morphometric description of the rudd Scardinius erythrophthalmus (Linnaeus) in the backwater zone of the Shumarovka River influenced by the Rybinsk Reservoir, lakes Chistoye and Sankhar. The rudd from the Shumarovka River belongs to the generation of the anomalously warm year 2010. According to the combination of analyzed features rudd from the Shumarovka River is similar to fish of this species in Lake Chistoye and different from rudd in the karst Lake Sanchar. The study suggests that scale initiation and formation in the lateral line and the number of pores of the seismosensory system in rudd depends on the rate of its development and growth at early life stage.

Keywords: rudd, morphology, Shumarovka River, Rybinsk Reservoir, Lake Chistoye, Lake Sankhar.
