Гидробионты как фактор регуляции потоков вещества и миграции элементов в водных экосистемах // Известия Самарского научного центра РАН. 2003. т.5, №2. с.249-255. http://www.ssc.smr.ru/ftp/2003/ssc52249.pdf АННОТАЦИЯ. Дана новая типология и классификация основных видов переноса вещества и миграции элементов. Эта классификация выделяет векторные и стохастические, а также циклические и нециклические миграции элементов. С учетом представлений В.И.Вернадского о биосфере, автором предложен термин "биокосная регуляция" миграции элементов и перемещений вещества. Даны примеры роли организмов в регуляции указанных видов миграции элементов и перемещений вещества, в том числе в регуляции в точках бифуркации траекторий миграции химических элементов. ABSTRACT: V.I.Vernadsky underlined the important role of living matter in determining the pattern of migrations of chemical elements on the surface of Earth, including the hydrosphere. On the basis of the data accumulated in hydrobiology, limnology, and biological oceanography, some conceptual conclusions could be made. The classification of migrations of elements, as proposed in this paper, can include the following types: vectorial and stochastic, cyclic and non-cyclic migrations. The role of living matter in regulation of that which proportion of matter (chemical elements) undergo any of those types of migrations is analyzed. Author considers both groups of factors (biotic and abiotic ones) as important in that regulation. The structurization of the migrations of chemical elements on the surface of Earth is under the combined and complex control of the both groups of the factors. Extending the area of usage of the unique adjective proposed by V.I.Vernadsky (biocosny, which means formed as a process and result of the combined and closely interwoven action of biotic and abiotic factors; the adjective consists of two parts, bio and cosny, the latter means inert in Russian and reflects the sum of abiotic factors), we consider the complex biocosny regulation of migrations of matter and chemical elements in the biosphere, including the regulation of dichotomies at the points of bifurcations among the vectorial and stochastic, as well as cyclic and non-cyclic types of their migrations.

Biocatalysis of matter transfer in a microcosm is inhibited by a contaminant: effects of a surfactant on Lymnaea stagnalis. - Doklady Biological Sciences, Vol. 373, 2000, pp. 397–399. [Translated from Doklady Akademii Nauk, Vol. 373, No. 2, 2000, pp. 278–280]. --Pellet excretion by the gastropods Lymnaea stagnalis feeding on the phytomass of macrophytes (such as Nuphar lutea) was as high as 4–7 mg absolute dry weight per gram wet weight of mollusks per 72 h. Pellet sedimentation contribute to vertical transfer of chemical elements in the ecosystem. The pellet composition varies depending on the species of the plants eaten by the mollusks. When L. stagnalis feed on N. lutea, the pellets contain, in addition to organic and inorganic carbon, nitrogen (N, 2.3–2.9%), phosphorus (P, 0.4–0.5%), and silicium (Si, 1.1–1.9%). The relative silicium content may be 30% higher than in the food phytomass. The surfactant tetradecyltrimethylammonium bromide (TDTMA, 2 mg/L) inhibited pellet production, their accumulation at the bottom of microcosms, and the matter transfer connected with this. The data obtained demonstrated a new aspect of the ecological hazard due to environmental pollution with TDTMA and other quaternary ammonium compounds at sublethal concentrations. According to the author opinion, other contaminants may also suppress pellet production, their accumulation at the bottom, and the matter transfer associated with that. --KEY WORDS: gastropods, Lymnaea stagnalis, Radix ovata, Physa fontinalis, Nuphar lutea, Taraxacum officinale, tetradecyltrimethylammonium bromide, TDTMA, mollusks, pellet sedimentation, vertical transfer, chemical elements, aquatic ecosystem, nitrogen, phosphorus, silicium, Si, ecological hazard, environmental pollution, quaternary ammonium compounds, sublethal concentrations, contaminants, matter transfer, xenobiotics, toxicity, bioassay, microcosm, detritus, feeding rate, invertebrates, water self-purification;
