The level-block approach to the analysis of ecological hazards of anthropogenic effects on the biota (the new conceptualization proposed by the author). 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). The inhibition of the filtration activity of filter-feeders may lead to the situation previously described as that of an ecological … of the second type.

Discovery of a new type of negative impact of pollutants on the biosphere, as a result of inhibition of water filtration by filter-feeders / suspension feeders. The water filtration and associated removal of suspended matter from water is part of migration of matter. As V.I. Vernadsky stressed, organisms are mediators of “biogenic migration of atoms in the biosphere”. This migration is partly implemented in the framework of pelagial–benthal coupling via the activity of filter-feeders, which remove the organic suspended matter from water and excrete pellets. The tables contains the following data: the average percentage of assimilated (16-90%) and non-assimilated (10-84%) food matter for 15 large taxa of invertebrates (Table 1); potassium bichromate inhibited water filtration by mussels Mytilus galloprovincialis (Table 2); surfactants, detergents, pesticides inhibited filtration by filter-feeders, marine and freshwater bivalves and rotifers (Table 3). A prediction was made: "Further research and experimental studies are expected to provide new evidence that sublethal concentrations of chemical pollutants induce a significant decrease in the filtration capacity of freshwater and marine filter feeders" (p.129). "The uncoupling process considered above is an anthropogenic violation of two basic laws (empirical rules or biogeochemical principles) of the biosphere functioning: (1) biogenic migration of atoms of chemical elements in the biosphere always tends toward its maximum expression; (2) on the geological time scale, the evolution of species gives rise to the forms of life that are stable in the biosphere, and is so directed that the biogenic migration of atoms in the biosphere increases" (p.129).]; DOI10.1023/A:1015385723150; https://www.researchgate.net/file.FileLoader.html?key=d988acb599e121964c48114374a87e8d;www.springerlink.com/index/28V23JBFADL1Y100.pdf; Full text see online free: http://www.scribd.com/doc/45913695; ----------------------------------------------- System.of.Principles.fulltext; -------------------Full text see online free: http://www.scribd.com/doc/45911862; Ostroumov S.A.

As a result of the author’s studies of filter-feeders (DAN, 1998, Vol. 362, P. 574-576; DAN, 2001, Vol. 378, P. 283-285), it is clear that the filtering activity of populations of filter-feeders in natural habitats might be significantly reduced if the concentrations of some pollutants reach certain levels. The role of filter-feeders as factors of water purification in ecosystems is so important that their inhibition is a danger for the entire ecosystem. The author emphasizes that not only the biodiversity of filter-feeders but also their level of functional (filtration) activity is to be protected. In order to do so, the author suggested establishing a new type of protected areas whose main purpose is to protect functionally active populations of filter-feeders, including bivalves and other organisms. Those protected areas could be named hydrobiological (some variants: biofiltering, or malacological) reserves (some variants: refuges, sanctuaries, etc.). The author formulated 5 principles of nature conservation requirements in malacological and hydrobiological reserves (Tabl. 3). Among them is principle 2, "conservation of filtration activity of organisms and populations". The paper contains data on how 5 detergents (1-50 mg/L) inhibited the filtration activity of Unio tumidus, Mytilus galloprovincialis, Crassostrea gigas (Tabl. 2); on effects on the efficiency of elimination (EEE) of suspended matter from water were measured (Tabl. 2); on the number of days (0.3 – 10) needed to filter the volume of aquatic (freshwater and marine) ecosystem by the local bivalves (a review of data from literature) (Tabl. 1). "I suggest that the existing system of protected terrestrial and water areas should be supplemented with special sites intended to conserve populations of filter-feeders. In addition to biodiversity conservation, these populations should be conserved because they fulfill a very important biogeocenotic function of water filtration and purification" (p.149). "The system of five principles…is proposed to provide an ecological basis of the environment conservation conditions at these sites (malacological and hydrobiological reserves)" (p.149).].

Abstract: In the paper, the author proposed a new approach to analyze the key ecological issue, the interactions between organisms in ecosystems. The new methodology proposed is inhibitory analysis. The author applied this approach to analyze trophic chains: the top–down control of plankton by benthic filter-feeders. This control, as the author’s experiments have shown, might be removed by chemical inhibitors (the latter may enter the ecosystem as pollutants). As an example, the author gives the results of his experiments on how surfactants [tetradecyltrimethylammonium bromide (TDTMA)] and synthetic detergents inhibited the control of plankton (Monochrystis lutheri) by mussels Mytilus galloprovincialis. The method was successfully applied to innovatively analyze the factors that are among reasons of eutrophication. Among new facts: the cationic surfactant TDTMA 1 mg/L inhibited the filtration rate of juveniles of marine bivalves Mytilus galloprovincialis, and the removal of cells of the algae Monochrysis lutheri from water (50 min, 26˚C)].
