Abstract An integral part of maintaining a favorable environmental situation on our planet is the observation of its individual objects, including special attention is paid to water bodies. This is due not only to the natural human need for its consumption, but also to other aspects of the anthropogenic factor, which includes unintentional pollution of the environment with industrial and other waste. The task of increasing the effectiveness of measures aimed at the effective performance of work on the collection of water and soil samples from individual reservoirs, as well as the collection, accumulation and processing of data on reservoirs through the introduction of a system of environmental monitoring of water bodies is being solved. Such a system will speed up the work of environmental organizations, and also contributes to the formation of a brief set of recommendations for restoration measures and will give an overall assessment of the ecological state of the reservoir. The purpose of this work is to automate the process of accounting and processing information about the results of laboratory studies of various types of samples and tests on the basis of the performed cycle of calculations to form estimates and recommendations on the ecological state of the reservoir and to make final reports.

Assimilation Capacity

The ability of a bay and gulf ecosystems to self-purification was estimated and the current ecological state of the Sevastopol Bay in whole and the separated parts of the bay was given as an example. A zoning by type of anthropogenic impact subject to the water exchange with the open sea and an influence of the Chernaya River run-off were taken into account. A comparative analysis of assimilation capacity of the most environmentally disadvantaged part of the Sevastopol Bay (the Southern Bay) and the clean water area, bordering on the open sea, was carried out. The hydrodynamic regime of the Sevastopol Bay was described using numerical modelling. The prospect, opportunity and examples of the methodology for assessing the assimilation capacity of marine ecosystems are demonstrated.

Mount Durmitor and the town of Zabljak as a unique hub of Montenegro, the first ecological state in the world, must also base their identity on the lakes in which they see their reflections multiplied as in crystal mirrors. The more thoroughly we learn about the lakes and evaluate them in a proper way, the more dazzling they appear to be. The lakes are not all that numerous. They will not be there for ever. They are evolutionary water bodies of low selfpurification potential.

The species composition of zooplankton in mineralized water bodies located in the Ulug-Khem basin (Republic of Tuva) was studied. These lakes have the status of natural monuments of regional significance. In total we recorded 53 species of microscopic Custaceans and Rotifers from 32 genera, 13 families, and 8 orders. Cladocera comprises 53% of the species. The dependence of the species diversity on the level of mineralization was revealed; 89% of the species were found in brackish water bodies. The zooplankton composition of the hyperhaline lakes Dus-Khol (Svatikovo) and Cheder has remained constant for many dozen years. The zooplankton includes some species known only from Republic of Tuva in Russia, namely, Microcyclops afganicus and Macrotrix tabrizensis. M. asiaticus and Alona irinae, rare for the fauna of Russia, live in the lake Haak-Hol. A decrease in the total numbers of zooplankton is observed in the lakes, namely: in the lake Dus-Khol, it has decreased by 4 times, in the lake Khadyn it has decreased by 10–19 times as compared to the middle of the last century. Despite the lack of intermediate information, we regard this as a consequence of anthropogenic impact. The emergence of an indicator of pollution (Brachionus nilsoni) in the lake Khadin confirms this version. At the same time, the stable finding of species rare for the fauna of Russia indicates the presence of favorable conditions for their development and life, which increases the value of the reservoirs themselves, which are already unique natural objects.

Abstract: Coastal ecosystems of northeastern Brazil have important biodiversity with regard to marine mollusks, which are insufficiently studied. Here we provide an inventory of mollusks from two sites in the estuary of the Paraíba River. Mollusks were collected in 2014 and 2016 on the coast and sandbanks located on the properties of Treze de Maio and Costinha de Santo Antônio. The malacofaunal survey identified 12 families, 20 genera and 21 species of bivalves, 17 families, 19 genera and 20 species of gastropods and one species of cephalopod. Bivalves of the family Veneridae Rafinesque, 1815 were the most representative, with a total of five species. Gastropods of the family Littorinidae Children, 1834 had the greatest species richness. The most abundant species were: Neritina virginea (Linnaeus, 1758), Brachidontes exustus (Linnaeus, 1758), Crassostrea brasiliana (Lamarck, 1819), Cerithium atratum (Born, 1778), Anomalocardia brasiliana (Gmelin, 1791), Parvanachis obesa (C. B. Adams, 1845), Phrontis polygonata (Lamarck, 1822), Littoraria angulifera (Lamarck, 1822), L. flava (King, 1832), Tagelus plebeius (Lightfoot, 1786), Echinolittorina lineolata (d'Orbigny, 1840) and Iphigenia brasiliensis (Lamarck, 1818). The results show that the study area has considerable species richness of Mollusca, requiring environmental monitoring in the region mainly due to the economic importance of some species to the local population.

Artificial Water

A brief review of the ecological state of artificial water bodies is presented on the example of the Voronezh and Matyr reservoirs located in the basin of the river. Voronezh. Ecological-geochemical interrelation of water areas of reservoirs and adjacent territories with anthropogenic sources of pollution located on them is shown. The basis of the research is the bioindication method for the communities of phytoplankton and microphytobenthos. Changes in the sanitary and biological quality of the waters have been studied in the reservoirs, which are related, in particular, to the effect of anomalously high summer air temperatures in 2010–2012 and in subsequent years, and for the Matyr reservoir against this background, an estimate of the effectiveness of the use of algobiotechnology is given.
