    Abstract of this paper, with some comment. ** The content of the article in short: A new solution to eutrophication. New concept of eutrophication control. Rating of this paper: In the top 25% of all articles scored by Altmetric. ** A new way of eutrophication control was suggested in the paper. The author suggested a new component of the measures against eutrophication: reducing the input of the chemical pollutants that weaken the potential of the filter-feeders for removing planktonic algae. The suggested way of controlling eutrophication is applicable to both freshwater and marine ecosystems. The article proposed a new idea, a new way of controlling eutrophication. The article is based on a series of the author's experiments with aquatic organisms (filter-feeders) that discovered and quantified relevant toxic effects of organic pollutants at sublethal concetrations. This article presented some new data to continue this line of research that is essential to the new solution to eutrophication. Among new facts that were reported in the paper, in addition to a substantial amount of relevant, related data previously obtained by the author: The liquid detergent (exemplified by the dish washing liquid, Fairy) 2 mg/L inhibited filtration by the bivalve mollusks, marine mussels (Mytilus galloprovincialis) within 2-23 min after addition, at temperature 22.5 ºС. This species of bivalve mollusks is one of key species in marine benthic ecosystems; it is one of ecological engineers that make a great impact on water quality. This is only one new fact that adds to many other facts (on how chemical pollutants can inhibit water filtration) discovered and reported by the author in other publications (papers and the book, Biological Effects of Surfactants). The paper presents a new approach to combat eutrophication.

    ABSTRACT: The article presents a new fundamental concept of how biodiversity helps towards a better environmental stability and water quality. The author made an innovative analysis of his experimental data and formulated the following fundamental principle: to maintain water quality, it is vital to protect the functionally active biodiversity of water ecosystems. In other words, according to the author’s new concept, the protection of functionally active biodiversity, including filter-feeders, is a key to maintenance of water quality. This concept was supported by many facts obtained in experiments of the author and reported in his previous publications. This article presents new facts in support of his concepts. Among new facts obtained and reported in the paper: a chemical pollutant (exemplified by the laundry detergent IXI, at a sublethal concentration 20 mg/L) inhibited water filtration by the aquatic bivalve mollusks, marine mussels Mytilus galloprovincialis (3-25 min, 18 pro mille, 22.8ºC). Another synthetic detergent (exemplified by the laundry detergent Deni-Automat), at a sublethal concentration 30 mg/L, also inhibited the water filtration by the marine bivalves oysters Crassostrea gigas (2-40 min, 25.2ºC).]. These new data as well as the other related data obtained by the same author and reported in his other publications, supported the author’s fundamental concept.

  • System of principles for conservation of the biogeocenotic function and the biodiversity of filter-feeders.
    Ostroumov SA.Dokl Biol Sci. 2002.2 comments

    ABSTRACT: System of principles for conservation of the biogeocenotic function and the biodiversity of filter-feeders.- Doklady Biological Sciences. 2002. Vol. 383: 147-150. Bibliogr. 15 refs. ISSN 0012-4966 (Print) 1608-3105 (Online). Distributed by Springer, orderdept@springer-sbm.com. ** Text of the ABSTRACT: As a result of the author’s studies of filter-feeders (previous publications in Russian: Doklady akademii nauk [DAN], 1998, Vol. 362, P. 574-576; Doklady akademii nauk [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).].

  • New definitions of the concepts and terms ecosystem and biogeocenosis.

  • 2015 Dec 03 2:40 p.m. (2 days ago)
    ABSTRACT: Ostroumov S.A. New definitions of the concepts and terms ecosystem and biogeocenosis. - Doklady Biological Sciences, 2002, Volume 383, p. 141-143. [MAIK Nauka/Interperiodica distributed by Springer Science+Business Media LLC. ISSN 0012-4966 (Print) 1608-3105 (Online)]. In 1935, the term 'ecosystem' was coined by Prof.A. Tansley. In the 1940s, another important term 'biogeocoenosis' was introduced by Prof. V. N. Sukachev. Since that time, a significant amount of new facts was accumulated in ecology. It is necessary to revisit the formulation of the basic concepts and terms in ecology, including the two terms mentioned above. The author proposed some new variants of the definition of the two terms that (1) reflect the modern understanding of the basics of ecology; and (2) avoid the vicious circle of using other terms that in turn request their definitions. The author realizes that the new variants of the terms cannot be ideal and some other variants of the definitions are also possible. 5 specific features of the proposed definition of ecosystem (Table 1). 8 specific features of the proposed definition of biogeocenosis, and 8 distinctions between the proposed definition and the classical definition by V.N.Sukachev (Table 2)].

  • A new type of effect of potentially hazardous substances: uncouplers of pelagial-benthal coupling.
    Ostroumov SA.Dokl Biol Sci. 2002.2 comments
    2015 Dec 03 04:58 a.m. (2 days ago)
    ABSTRACT of this article: A new type of effect of potentially hazardous substances: uncouplers of pelagial–benthal coupling. - Doklady Biological Sciences. 2002. Vol. 383 (1-6): 127-130. Bibliogr.15. ISSN 0012-4966. 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 or driving force 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 is 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).]; DOI 10.1023/A:1015385723150;

  • Identification of a new type of ecological hazard of chemicals: inhibition of processes of ecological remediation.
    Ostroumov SA.Dokl Biol Sci. 2002.2 comments
  • 2015 Dec 03 04:51 a.m. (2 days ago)
    ABSTRACT: Identification of a New Type of Ecological Hazard of Chemicals: Inhibition of Processes of Ecological Remediation. - Doklady Biological Sciences, Vol. 385, 2002, pp. 377–379. Translated from Doklady Akademii Nauk, Vol. 385, No. 4, 2002, pp. 571–573. The author (Moscow University) discovered and quantitatively characterized a new type of ecological hazard of chemical pollution of water, which involves inhibition of important processes of ecological remediation of ecosystems (water filtration by aquatic bivalves). Experiments were performed using mollusks (oysters), Crassostrea gigas Thunberg, and a cell suspension in the seawater. The cell suspension was a model of suspended matter in aquatic ecosystem; this species of one-cell organisms was taken just for convenience, as a model of suspended particles. The laundry detergent Lanza-Automat inhibited water filtration by oysters (Crassostrea gigas). As a result, the removal of the suspended particles from water was inhibited. This demonstrated a new type of ecological hazard caused by water pollution with chemical pollutants at sublethal concentrations. This hazard is associated with the fact that chemical pollution of water causes inhibition of the physiological activity of filter-feeders, thereby inhibiting the important ecological processes of water filtration. These ecological processes contribute significantly to improving water quality, water purification and the related remediation of aquatic ecosystems (their ecological repair).

    ABSTRACT: On the biotic self-purification of aquatic ecosystems: elements of the theory. - Doklady Biological Sciences, 2004, Vol. 396, Numbers 1-6, pp. 206-211. This article presents a system of elements of a new theory of biotic maintaining the natural purification potential of aquatic ecosystems. The fundamental elements are formulated for a qualitative theory of the multifunctional (polyfunctional) role of the biota in improving water quality and doing self-purification of water in aquatic ecosystems. The elements of the theory covers the following: the sources of energy for the mechanisms of water self-purification; the main functional blocks of the system of self-purification; the system of the main processes that are involved; the analysis of the degree of participation of the main large taxa; the reliability of the mechanisms of water self-purification; regulation of the processes; the response of the mechanisms of water self-purification towards the external influences (man-made impacts, pollution); and some conclusions relevant to the practice of environment protection. In support of the theory, the results are given of the author's experiments which demonstrated the ability of some pollutants (surfactants, detergents, and some others) to inhibit the water filtration activity of aquatic invertebrate filter-feeders, namely, the bivalve mollusks, including mussels Mytilus galloprovincialis, Mytilus edulis, and oysters Crassostrea gigas.

    DOI:10.1134/S0012496609050159; In the presence of this aquatic, submerged, free-floating higher plant (rigid hornwort) in water system, it was occured that a decrease in concentrations of the four heavy metals (cadmium; copper; lead; zinc; Cu, Zn, Cd, and Pb) in the water medium accelerated. The aquatic macrophytes served as a factor to speed up the water purification (decontamination) process in the aquatic system. The method for measuring the heavy metals was stripping voltammetry.

    The results of this study are really interesting and innovative. I had some experience of studying phytoremediation with this plant species, Myriophyllum aquaticum (parrot feather). It has a high potential for decontamination of aquatic environment. This paper provided new facts in support of good prospects of using this plant species. The test system with rotifers (Brachionus calyciflorus) feeding on an algal species (Nannochloropsis spp.) is also an interesting feachure of this paper. This test system was successfully used also in this paper:www.researchgate.net/publication/200578650;

  • The aquatic macrophyte Ceratophyllum demersum immobilizes Au nanoparticles after their addition to water.
    Ostroumov SA.Dokl Biol Sci. 2010.1 comment
    2015 Nov 30 2:30 p.m. (5 days ago)edited 1 of 2 people found this helpful
    In the paper, it was discovered that the aquatic higher plant (macrophyte) hornwort (other English names: rigid hornwort, coontail, coon's tail; the Latin name: Ceratophyllum demersum) immobilized gold (Au) nanoparticles after their addition to water. This is the first time it was shown that the nanoparticles of gold (Au) in substantial amount bind to the living biomass of the aquatic macrophyte (namely, Ceratophyllum demersum). The concentrations of Au were measured in the samples of the phytomass using neutron activation analysis (NAA). As a result of the binding and/or immobilization of the nanoparticles, the amount of Au in the samples of the phytomass increased manifold (by a factor of 430) above the background level of gold in the plant tissues. The increase was by two orders of magnitude. The new data added some new information to the modern vision of the multifunctional role of the biota in the migration of elements in aquatic ecosystems, and water self-purification. Also, the result added new information to the studies of interactions of Au with organisms that may contribute to new biotechnologies (namely, phytotechnologies to remove heavy metals from water).
