- Аннотация: S.A. Ostroumov, X. Cai, Study of chemico-biotic interactions in the biosphere and hydrosphere and contribution to scientific basis of protection of biodiversity of organisms including marine hydrobionts.Sergei A. Ostroumov S.A. 1, X. Cai 2, 1 Lomonosov Moscow State University, Faculty of Biology, Moscow, 119991, Russia;2 Shenzhen MSU-BIT University, No. 299, Ruyi Road, Longgang District, Shenzhen, Guangdong Province, P.R. China;ar55[at]yandex.ru;Ecological and environmental research conducted by the co-authors led to obtaining new experimental data on chemico-biotic interactions including biological effects of man-made chemicals and emergent chemical pollutants on biological organisms. Some of the new data contributed to development of an innovative approach to understanding function of aquatic ecosystems, and multi-functional role of aquatic biodiversity in maintaining and improving water quality (water self-purification). These considerations were published in a series of publications of the first of the co-authors of this abstract (namely, S.A.Ostroumov) in the journals ‘Doklady Biological Sciences’, ‘Russian Journal of General Chemistry’, ‘Hydrobiologia’, ‘Water Resources’, and ‘Russian Journal of Ecology’, as well as in some other academic journals. As a result, these publications formed an interdisciplinary qualitative theory of ecosystem-driven and polyfunctional (multifunctional) biota-driven water self-purification. The results and conclusions of this theory might be applied to further development of the scientific basis for protection of biodiversity including biodiversity of aquatic organisms. The traditional approach to protection of biodiversity is based on the principle of conservation of the diversity of species of biological organisms. When the existence and fate of the populations of given species is endangered, the situation is considered bad and the conclusion follows that the protection measures are needed. When the existence of the given species is not endangered, the situation is considered as acceptable and it is thought that no worries about this species are needed. The new data obtained and the innovative theoretical considerations mentioned above lead us to a conclusion that the traditional approach needs to be corrected and supplemented. In the presentation, we plan to prove that the additional input to the scientific basis of protection of biodiversity is needed, and additional attention and protection should be given to quantitative parameters of ecosystem function of the populations of the species under consideration. An example is the water-filtering activity of filter-feeders (however it is only one of many examples). We plan to give new examples in support of this consideration, in addition to previously published examples. A relevant result of the abovementioned theory of ecosystem-driven and biota-driven water self-purification is a better understanding of the indispensable role of biota in maintaining water quality of water resources. The practically important conclusion is that it is absolutely necessary to protect aquatic biodiversity in order to protect water quality. It is important for both freshwater and marine water systems.
