- Rotifers: Rotifers are an important part of the freshwater zooplankton, being a major foodsource and with many species also contributing to the decomposition of soil organic matter. Most rotifers are around 0.1–0.5 mm long, and are common in freshwater environments throughout the world. The word "rotifer" is derived from a Latin word meaning "wheel-bearer", due to the corona around the mouth that in concerted sequential motion resembles a wheel (though the organ does not actually rotate). The coronal cilia create a current that sweeps food into the mouth. Rotifers eat particulate organic detritus, dead bacteria, algae, and protozoans. They eat particles up to 10 micrometres in size. Like crustaceans, rotifers contribute to nutrient recycling. For this reason, they are used in fish tanks to help clean the water, to prevent clouds of waste matter.(Wikipedia was used).

- Explanation of methodology (some details on the choice of the biological species and chemicals to study). Why the great pond snail and freshwater mussels were studied in this reseach project: they are among the most common benthic species of invertebrates in water habitats of Eurasia. Their biomass is one of the biggest, or just the biggest, among aquatic invertebrates in Eurasia and other parts of the world. Why the plant species, Nuphar lutea (Yellow Water-lily) , was used in this research project: it is one of the most common aquatic plant species in the freshwater habitats of Eurasia. Why the plant species, Taraxacum officinale, was used in this research project: it is a common laboratory practice to feed the great pond snail with leaves of this higher plant. Why the synthetic surfactants ТDТМА (tetradecyltrimethylammonium bromide) and SDS (sodium dodecyl sulfate) were used: they are representatives of the two major classes of synthetic surfactants, namely, cationic surfactants, and anionic surfactants. These two chemicals were studied in many other publications of Dr. Sergei Ostroumov, so that lots of data to compare toxic effects of these chemicals on organisms are available. A detailed explanation of methodology was also published in the book Biological Effects of Surfactants (Ostroumov, 2005, https://www.researchgate.net/publication/200637626)
- Comment on the biological species that were studied in this paper: the great pond snail is a species of large air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae. Range Description: A widespread species distributed in Asia (central, north and south and southeast), north America, north Africa and New Zealand. The great pond snail has a shiny yellowish brown shell.Nuphar lutea (Yellow Water-lily) is an aquatic plant of the family Nymphaeaceae, native to temperate regions of Europe, northwest Africa, and western Asia.Unio is a genus of medium-sized freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels. Unio is the type genus of the family Unionidae. About this family: The range of distribution for this family is world-wide. It is at its most diverse in North America, with about 297 recognised taxa, but China and Southeast Asia also support very diverse faunas. Freshwater mussels occupy a wide range of habitats, but most often occupy lotic waters, i.e. flowing water such as rivers, streams and creeks.
- Explanation of terminology: pellets are the particles of the undigested organic matter (mainly biomass of undigested food) that the aquatic mollusks (snails and freshwater mussels) excrete so that these mollusks function as engines that drive the transfer of a significant amount of the organic matter through aqautic ecosystems.

- An aquatic ecosystem: a large-scale diversified bioreactor with a water self-purification function.Dokl Biol Sci. 2000.3 commentsAbstract: An aquatic ecosystem: a large-scale diversified bioreactor with a water self-purification function. — Doklady Biological Sciences, 2000. Vol. 374, P. 514-516. 3 tables. Bibliogr. 15. ISSN 0012-4966. Distributed by Springer, orderdept@springer-sbm.com. ** Innovative conceptualization: The author developed a new fundamental concept of aquatic ecosystem as a multi-functional bioreactor. One of the key functions of that bioreactor is upgrading water quality via a multi-component biomachinery of water self-purification. ** New facts: Contribution of the main groups of aquatic organisms (heterotrophic bacteria, fungi, cyanobacteria and microalgae, protozoans, higher plants, invertebrates, fish and amphibians) to water self-purification: comparison and analysis (Tabl.1). Relatively small effects of a synthetic non-ionic surfactant (Triton X-100 or TX100, 4-5 mg/L) on marine bacteria Hyphomonas sp. MHS-3 (5 mg/L), and on bacteria Hyphomonas sp. VP-6 (5-10 mg/L), a significant inhibition by the synthetic surfactant Triton X-100 of the water filtration by the marine mussels Mytilus edulis (4 mg/L), and by the freshwater mussels Unio tumidus (5 mg/L). The negative (inhibitory) effects of a synthetic cationic surfactant TDTMA 1 mg/L on the marine mussels M. galloprovincialis (Tabl.2); the inhibition of feeding: effects of the synthetic surfactant TX100 1-5 mg/L on the freshwater mussels Unio tumidus, inhibitory effects of the synthetic surfactant TDTMA 1-2 mg/L on the freshwater mussels U. pictorum; effects of a number of synthetic surfactant and detergents, namely, TDTMA 1 mg/L, anionic surfactant SDS 1.7 mg/L, detergents 6.7 – 50 mg/L, shampoo (namely, the shampoo) AHC 5-60 mg/L (sublethal concentrations) on the marine mussels M. galloprovincialis; TX100, TDTMA (2 mg/L), laundry detergent (Tide-Lemon, 75 mg/L) on the freshwater mollusk (the pond snailLymnaea stagnalis) (Tabl.3).** A fragment of the text: "Sublethal concentrations of contaminants may inhibit vital activities of other organisms involved in the function of an ecosystem as an analogue of a bioreactor. This finding provides a deeper insight into the mechanisms of anthropogenic impact on biosphere. The concept put forward in this work emphasizes that intactness of the whole range of biological diversity of hydrobionts [aquatic organisms] is required to provide effective functioning of an ecosystem as an analog of a water self-purification bioreactor. Therefore, the monetary cost estimates of ecosystems and the biota should be increased" (p. 516).

- The hazard of a two-level synergism of synecological summation of anthropogenic effects.Dokl Biol Sci. 2001.3 commentsAbstract: The author identified a new type of ecological hazard of anthropogenic impact (using chemical pollution as an example), which he proposed to term “synecological summation” or “synergistic summation” of anthropogenic effects on organisms of two adjacent trophic levels. ** NEW FACTS: in the study reported in the paper, the following new type of environmental hazards was found. It was shown that even some relatively mild influences on organisms of two adjacent trophic levels may eventually produce a synergistic, pronounced and definitely undesirable effect which will lead to an abnormal increase in the abundance of organisms of one of the trophic levels. The concrete examples of that type of synergism were found when anthropogenic impacts affected the organisms of two adjacent trophic levels (bivalves and algae). Some new bioeffects of the action of the synthetic detergent (exemplified by the laundry detergent, namely, the detergent 'Vesna') (1 mg/l) on the bivalves, oysters Crassostrea gigaswere described. Also, some new effects of the detergent (exemplified by the laundry detergent, namely, the detegent 'IXI') (10 mg/l) on the marine mussels Mytilus galloprovincialis, were found; also, new effects of the detergent (exemplified by the laundry detergent, namely the detergent 'Tide-Lemon') (50 mg/l) on M. galloprovincialis were discovered. ** CONCLUSION: The hazard of simultaneous influence of contamination of environment (e.g., by detergents) on organisms of the two trophic levels may occur when the polluting chemicals produce effects on algae and bivalves that are filter-feeders. It means that a new type of environmental hazards was discovered.

- Responses of Unio tumidus to mixed chemical preparations and the hazard of synecological summation of anthropogenic effects.Dokl Biol Sci. 2001.6 commentsAbstract: Responses of the freshwater bivalve Unio tumidus to mixed chemical preparations and the hazard of synecological summation of anthropogenic effects. - Doklady Biological Sciences, 2001, Volume 380, p. 492-495. ISSN 0012-4966 (Print) 1608-3105 (Online). DOI 10.1023/A:1012344026176. The author introduced a new concept and term, “the synecological summation of the effects of anthropogenic factors on organisms”. In the new author’s experiments, the effects of commercial detergents, which are chemical mixtures, on bivalves (e.g. effects of the laundry detergent OMO on the freshwater mussels Unio tumidus) were discovered and studied. Detergents exert two types of hazardous effects on organisms and ecosystems: the phosphorus-induced stimulation of phytoplankton growth and surfactant-induced inhibition of filter-feeders. Because filter-feeders are an effective natural factor of control of unicellular plankton populations, the two types of the detergent-induced effects on ecosystem facilitate the growth of phytoplankton populations. Therefore, these effects sum together, thereby increasing the hazard of the man-made impact on the ecosystem. The results contribute to a better understanding of the potential ecological danger of pollutants for integral functions of ecosystems. It is the synecological summation of the effects of anthropogenic factors on plankton populations and filter-feeders that is of particular concern. The interaction between populations of plankton organisms and filter-feeders that feed on plankton should be taken into consideration in the studies on the ecological effects of synthetic detergents on these populations. Situations of man-made impact should be analyzed with using the synecological approach to the problem. http://sites.google.com/site/2001dbs380p492unio/; www.springerlink.com/index/L33309208H28L87R.pdf; DOI 10.1023/A:1012344026176;

- 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.Dokl Biol Sci. 2002.3 commentsABSTRACT: 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).].

- 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.Dokl Biol Sci. 2002.2 commentsABSTRACT 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;

- 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).

- On the biotic self-purification of aquatic ecosystems: elements of the theory.Dokl Biol Sci. 2004.3 commentsFull text free: https://www.researchgate.net/publication/200567576_On_the_biotic_self-purification_of_aquatic_ecosystems_elements_of_the_theoryABSTRACT: 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.

- Decreasing the measurable concentrations of Cu, Zn, Cd, and Pb in the water of the experimental systems containing Ceratophyllum demersum: the phytoremediation potential.Dokl Biol Sci. 2009.1 commentDOI: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.

- Using rotifer population demographic parameters to assess impacts of the degradation products from trinitrotoluene phytoremediation.Ecotoxicol Environ Saf. 2003.1 commentThe 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.Dokl Biol Sci. 2010.2 commentsIn 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).

- 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.
- [An amphiphilic substance inhibits the mollusk capacity to fliter phytoplankton cells from water].Izv Akad Nauk Ser Biol. 2001.3 commentsThe term 'amphiphilic substance' here means 'a surfactant' or 'a surface active substance', namely, sodium dodecylsulfate (SDS).
- Similar results were obtained with/at lower concentrations of SDS. The results on the lower concentrations were published in the book 'Biological Effects of Surfactants'. More info on the book see here: https://www.researchgate.net/publication/200637626
- Presence and distribution of mosquito larvae predators and factors influencing their abundance along the Mara River, Kenya and Tanzania.Springerplus. 2015.1 commentI think it is a very interesting important study. This research project is useful to control malaria. My recommendation is to include the word 'malaria' and /or 'malaria control' to the list of key words.
- Distribution and abundance of schistosomiasis and fascioliasis host snails along the Mara River in Kenya and Tanzania.Infect Ecol Epidemiol. 2014.1 commentThis article is exploring new links between issues of ecology (trophic web, trophic chains) and medicine (malaria control). It is very interesting.
- Heavy metal adsorption properties of a submerged aquatic plant (Ceratophyllum demersum).Bioresour Technol. 2004.1 commentI have studied this species of plants also. It was also a factor to remove some metals from water. It is a useful paper, congratulations to the authors!
