http://scipeople.ru/publication/111606/ The goal of this review is to provide a short summary of a series of 25 innovative publications on environmental science and ecology. The papers were authored by scientists of Moscow State University and their co-authors. The review is not a comprehensive analysis of this broad area but a summary of some selected examples which are useful both in advancing further research and in modernization of environmental education. The review is structured and the text is divided into short sections that are easy to read.

The full text is made available online free: See: http://www.researchgate.net/profile/Sergei_Ostroumov/blog/5152_TextsOnlineFree; http://www.scribd.com/doc/44105992; Abstract: On the basis of the previous publications, our new data and the existing scientific literature, we have formulated some fundamental principles that characterize the pivotal roles of the biodiversity of filter-feeders in ecosystems. Among those roles are: (1) the role of ecological repair of water quality, (2) the role of contributing to reliability and stability of the functioning of the ecosystem, (3) the role of contributing to creation of habitat heterogeneity, (4) the role of contributing to acceleration of migration of chemical elements. It is an important feature of the biomachinery of filter-feeders that it removes from water various particles of a very broad range of sizes. Another important principle is that the amount of the organic matter filtered out of water is larger than the amount assimilated so that a significant part of the removed material serves no useful function to the organism of the filter-feeder, but serves a beneficial function to some other species and to the ecosystem as a whole. The new experiments by the author additionally demonstrated a vulnerability of the filtration activity of filter feeders (e.g. bivalves and rotifers) to some xenobiotics (tetradecyltrymethylammonium bromide, heavy metals and some others).

We assembled information on 119 species of freshwater macroinvertebrate invaders in North America and Europe, and compared them to all native freshwater species in North America and Europe. We tested whether the invaders were a random or selected group among taxa (phylum or class), water quality requirements, and feeding habit. We found that freshwater macroinvertebrate invaders are not a random selection of species, and are overrepresented by molluscs and crustaceans, while taxa richness of native communities are dominated by insects. Over 35% of native species of aquatic invertebrates in North America are only able to live in areas with excellent or very good water quality, and are intolerant of organic pollution. In contrast, all invaders are tolerant of at least moderate amounts of organic pollution. There was a significant difference in the distribution of feeding habits between native species and invaders: collector-filterers (including suspension feeders) were 2.5–3 times more abundant, and predators were 3–4 times less abundant among invaders than among native invertebrates. The ongoing spread of exotic species affects the biodiversity of selected taxa, shifts communities toward greater tolerance of organic pollution and increases the numbers of suspension feeders, thereby enhancing benthic pelagic coupling in waterbodies with high densities of invaders. Because these processes are very similar in Europe and North America, we suggest that the observed patterns may have a common global effect.

The mankind is still far from establishing harmonious relations with it. However, permanently progressing destruction of natural complexes by the technogenic civilization necessitates some new revolutionary approaches to their preservation. That is why it is so important to study the relationships and interactions between living organisms. One of the most important roles in this “orchestra” is played by numerous invertebrates which filter the water and improve water quality.

The synecological approach to the problem of eutrophication. - Doklady Biological Sciences, Vol. 381, 2001, p. 559–562. http://scipeople.com/uploads/materials/4389/Danbio6_2001v381n5.E.eutrophication.pdf [Translated from Doklady Akademii Nauk (DAN), Vol. 381, No. 5, 2001, p. 709–712. Russian Text] ISSN 0012-4966. DOI 10.1023/A:1013378505630. The author proposed a new solution to the problem of eutrophication. This new vision is based on a synecological approach. In the paper, the author proposes a new two-component solution in order to protect the aquatic ecosystem from eutrophication. First, it is essential to reduce the input of nutrients. Second, it is equally important to reduce the input of the pollutants which weaken the potential of the ecosystem for removing the biomass of phytoplankton by filter-feeders. Those pollutants include surfactants, detergents, and some other compounds. Because synecology is one of key approaches in our analysis, this concept of counteracting eutrophication can be called a synecological solution to the problem. New experimental results: the detergent ‘Fairy’ inhibited the filtration rate of mussels Mytilus galloprovincialis; this complements the earlier data of the author on how detergents affect filter-feeders. --KEY WORDS: danger, chemical pollution, hazards, xenobiotics, synthetic, surface-active agents, surfactants, laundry detergents, heavy metals, mixtures, eutrophication, water filtration, clearance rate, invertebrates, pellets, filter-feeders, suspension feeders, bivalves, mollusks, rotifers, mussels, Mytilus, edulis, galloprovincialis, Crassostrea gigas, Dreissena, Unio, phytoplankton, zooplankton, algae, Daphnia, aquatic, ecosystems, sustainable, use, water resources, environmental safety, control, pollution, new, approach, solving, man-made reservoirs. --Остроумов С.А. Синэкологические основы решения проблемы эвтрофирования // Доклады академии наук (ДАН). 2001. том 381. № 5. С.709-712. Видение автором нового решения проблемы эвтрофирования основывается на синэкологическом подходе. Автор предлагает новый подход - двухкомпонентное решение в целях защиты водных экосистем от эвтрофирования. Оба компонента в равной степени важны и должны реализовываться (применяться на практике) одновременно. Во-первых, необходимо снизить поступление биогенов. Во-вторых, равным образом важно снизить поступление поллютантов, которые ослабляют потенциальную способность экосистем удалять биомассу фитопланктона благодаря активности фильтраторов. Эти поллютанты включают в себя поверхностно-активные вещества, детергенты и некоторые другие. Детергент Fairy ингибировал фильтрационную активность мидий Mytilus galloprovincialis, что дополняет ранее полученные данные автора о том, как детергенты воздействуют на фильтраторов. Поскольку синэкология – один из ключевых подходов в нашем анализе проблемы, эта концепция противодействия эвтрофирования может быть названа синэкологическим решением проблемы. --Ключевые слова: опасность химического загрязнения, ксенобиотики, синтетические поверхностно-активные вещества (ПАВ), детергенты, синтетические моющие средства (СМС), тяжелые металлы, смесевые препараты, эвтрофикация, фильтрация воды, беспозвоночные, пеллеты, фильтраторы, двустворчатые моллюски, коловратки, мидии, Mytilus edulis, Mytilus galloprovincialis, Сrassostrea gigas, Dreissena, Unio, фитопланктон, зоопланктон, Daphnia, водные экосистемы, устойчивое использование водных ресурсов, экологическая безопасность, борьба с загрязнением и эвтрофикацией, новый подход к решению проблемы.
