Приведены отобранные наиболее значимые фрагменты из монографии Э. С. Кульпина «Социоестественная история. От метода – к теории, от теории – к практике», опубликованной в 2014 г. издательством МБА и в том же году переизданной в качестве электронной книги издательством «Учитель». We open the present volume of the journal with addressing to the fundamental legacy of the founder, main creative source and promoter of socio-historical approach – Eduard Salmanovich Kulpin. In what follows we present the most elaborated and essential parts from his book “Socio-Natural History: From Method to a Theory, from Theory to Practice” published in 2014. This publication was discussed and approved at the Round Table “Socio-Natural History: Prospects of development” held in the Institute of Oriental Studies of the Russian Academy of Sciences on March 11, 2016.

Russian Journal of Ecology, Vol. 36, No. 6, 2005, pp. 414–420. Translated from Ekologiya, No. 6, 2005, pp. 452–459; ABSTRACT: Principles of the theory of the ecological mechanism of water self-purification based on multiple functions of the biota in freshwater and marine ecosystems are formulated. In developing this theory, the results of the author’s experiments with filtering hydrobionts have been used. These results indicate that the water selfpurification mechanism is vulnerable to the impact of some pollutants and, in particular, surfactants. Conclusions drawn on the basis of the theory have practical significance for biodiversity conservation and for the sustainable use of the biological resources of aquatic ecosystems. The first paper to formulate in detail the new qualitative theory of multifunctional activity of organisms in improving water quality, in other words, the theory of water self-purification by organisms. http://5bio5.blogspot.com/2014/03/article-on-multifunctional-role-of.html ; http://www.researchgate.net/publication/227317445_On_the_Multifunctional_Role_of_the_Biota_in_the_Self-Purification_of_Aquatic_Ecosystems; link.springer.com/article/10.1007%2Fs11184-005-0095-x‎; Additional data in support of the conclusions of this paper: see the book: Biological Effects of Surfactants.

On the Multifunctional Role of the Biota in the Self-Purification of Aquatic Ecosystems. - Russian Journal of Ecology, Vol. 36, No. 6, 2005, pp. 414–420. Translated from Ekologiya, No. 6, 2005, pp. 452–459. Moscow State University, Vorob’evy gory, Moscow, 119991, Russia; Abstract. It is the first publication that formulated a detailed conceptualiztion of principles of the ecological mechanism of water self-purification based on multiple functions of the biota in freshwater and marine ecosystems. In developing this fundamental in-depth analysis and formulating a new system of fundamental principles, the results of the author’s experiments with water filtering by filter-feeders have been used. These author's results discovered that the water self-purification mechanism is vulnerable to the impact of some pollutants and, in particular, synthetic surfactants and detergents. Conclusions drawn on the basis of the theory have practical significance for biodiversity conservation and for the sustainable use of the water resources and biological resources of aquatic ecosystems. http://www.springerlink.com/content/y6370w774lk7g786/; DOI 10.1007/s11184-005-0095-x; Additional details, and relevant publications see at: http://www.researchgate.net/profile/Sergei_Ostroumov/blog/13782_Worldwideevaluationsevidenceofmerit; [Main innovations made by Dr. S.A.Ostroumov]; A related paper see: Hydrobiologia. v.469:117-129. see: http://www.researchgate.net/profile/Sergei_Ostroumov/blog/13471_Hydrobiologia_v469117-129; Hydrobiologia. 2002. vol. 469, pages 117-129.

On the Biotic Self-purification of Aquatic Ecosystems: Elements of the Theory //Doklady Biological Sciences, Vol. 396, 2004, pp. 206–211. An innovative paper which generalizes and systematizes the basics of the theory of the multifunctional role that the biota plays in the self-purification and ecological remediation of aquatic (freshwater and marine) ecosystems. The author used the results of his experimental data, previous analyses and the theory of the function of aquatic ecosystems that was developed by Academician A.F.Alimov. Translated from Doklady Akademii Nauk, Vol. 396, No. 1, 2004, pp. 136–141. The original paper was presented to the journal by Academician M.E. Vinogradov
