The quality of the water and bottom sediments of the Rybinsk Reservoir, on the adjacent territory of which the Cherepovetskiy Metallurgical Plant PJSC “Severstal” is located, which has an adverse effect on the state of the water body is investigated. The pollution of water and bottom sediments by the metallurgical plant in the northern part of the Rybinsk reservoir was assessed in connection with the planned construction of a pulp and paper mill (PPM) at the site of the study.

Long-term dynamics of the aquatic toxicity was studied in the Rybinsk Reservoir. According to the biotesting, the Volga and Sheksna reaches were the most polluted areas, which were exposed to household and industrial wastewater, as well as to the diffuse runoff from agricultural land and major highways. The relationships between the parameters of toxicity and indicators of the chemical composition of water were analyzed.

A model of phytoplankton development within a reservoir including the description of kinetics of its interactions in the ecosystem and internal water exchange of the reservoir has been presented. The carried out calculations of changes of the cyanobacteria and diatom algae biomass in the Rybinsk Reservoir in the vegetation period have shown their satisfactory convergence with the fi eld observations data.

Agroecotourism is a relatively young branch of tourist industry in our country, at the same time it has become very popular abroad. The article considers some problems related to the development of rural ecotourism on the Yurshinsky island of Rybinsk reservoir. Various landscapes can be seen on the Yurshinsky island, escaping flowage of the Rybinsk reservoir area, where unique samples of Russian nature have remained untouched. The territory of island makes 792 hectares, half of its land is occupied by woods, and now all island has a status of specially protected area. Moose breeding farm is recommended to be established as the object of rural ecotourism on the Yurshinsky island, as its operation allows the tourist season last all-year-round. Ecological conditions of the territory need to be assessed before the organization of a moose farm and other objects of agroecotourism. Therefore we selected several soil samples to perform chemical analysis as the soil represents the knot of interrelations in biosphere and a lack or surplus of both vital, and toxic chemical elements in the soil will lead to their lack or surplus in plants grown up on such soils and in animal organisms which eat the given plants.

An approach is proposed for ranking the quality of freshwater ecosystems by the state of bivalve mollusks living in them. Cardioactivity indicators and accumulation of metals in the tissues of the mollusks from various waters of the eastern part of the Gulf of Finland and the Rybinsk Reservoir were used to characterize the ecosystems, and an original hyperosmotic test was used to analyze the functional state of the mollusks.

Second Period

Qualitative and quantitative phytoplankton compositions of 10 Montenegrin lakes were investigated in the summer of 2007. The obtained results were compared with a previous study-period that was undertaken two decades ago. In the first period, diatoms numerically dominated the phytoplankton community in all studied lakes, while in the second period, the same was observed only in three of the ten lakes; in other studied lakes the relative contributions of green algae, dinoflagellates and/or cyanobacteria increased, while the contribution of diatoms decreased. The shift observed in phytoplankton composition and diversity in some of the studied lakes indicates an increase in the trophic level over the two decades. The sustainable management plan of the aquatic ecosystems in Montenegro should include the establishment of an environmental monitoring system in order to record any alterations that may take place in water quality.
