ABSTRACT
System of principles for conservation of the biogeocenotic function and the biodiversity of filter-feeders.- Doklady Biological Sciences. 2002 (November). Vol. 383: 147-150. Bibliogr.15 refs. ISSN 0012-4966. Distributed by Springer, orderdept@springer-sbm.com.
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 new facts, the 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).
Statements from this paper:
"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).].

In short, according to this paper, the point is to give special attention to those aquatic organisms which are vital in maintaining good aquatic habitats. These are the organisms that are involved in water self-purification.
