Dr. Tamara Leont'evna Poddubnaya (nee Protopopova) was born 18 February 1930 in Rostov-na-Donu, a large city on the Don River in Southern Russia. After graduating the Rostov University in 1953 she joined the Biological Station in Borok, which later became the Institute for Biology of Inland Waters at Rybinsk Reservoir, located on the Upper Volga River in Northern Russia. Here she spent the remaining 57 years of her lifetime, working in the same research institute. In 1962, she received her Cand. Biol. Sci. (= Ph.D.) degree in Moscow; her thesis (in Russian) was entitled, "Studies on the biology of mass species of tubificids (Limnodrilus newaensis Mich. and Limnodrilus hoffmeisteri Clap.) of the Rybinsk Reservoir”.

A survey of surficial bottom sediments of the Rybinsk reservoir on the Volga, one of the largest and highly regulated rivers in Europe, revealed unknown species of the genus Placoneis. Detailed morphological observation using light and scanning electron microscopes allowed to describe this as P. mologaensis sp. nov. The species is characterized by linear-elliptical valves with slightly pronounced poles and conspicuous combination of other features, such as radial pattern of coarsely punctate uniseriate striae, bowtie-shaped central area without of isolated stigma, and raphe branches with heteromorphous terminal fissures. Ultrastructurally, P. mologaensis shows external areolar openings placed in depressions, which vary markedly in shape from round to slit-like. The new species is compared with similar and misidentified species and distributional data are provided based on confirmed records from the Pleistocene of the Boreal regions of Europe.

The author offers mapping and geoecological analysis of the Russian Federation regions presence in the state program “Environmental Protection”. The unequal distribution of the program’s targets and activities in different regions is revealed. A considerable number of relevant environmental problems for several mentioned regions have not been reflected in the program. It is important to increase the area of specially protected natural areas for a significant number of subjects of the Russian Federation. The status “part of the territory occupied by specially protected natural territories of Federal value in the total area of the subject of the Russian Federation” is recommended to be assigned all regions of Russia. Identification and elimination of objects of accumulated environmental damage that threat to the Volga river is relevant, at least for all the regions in which the Volga flows. Not all regions with a high level of air pollution and/or large masses of air pollutants have the indicator “reduction of total emissions for the reporting year”. It is necessary to increase the Program of measures for the protection of rare and endangered species of plants and to expand the list of regions in which it is planned to protect rare and endangered species of animals.

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.
