Original Russian Text Copyright © 2003 by Biologiya Morya, Ostroumov. On the Fourth International Conference “Water Ecosystems and Organisms-4” [CHRONICLE] S. A. Ostroumov Moscow State University, Moscow, Russia The Fourth International Conference (poster session)“Water Ecosystems and Organisms-4” took place in Moscow on June 19, 2002. The conference was organized under the aegis of several scientific organizations including the Hydrobiological Society at the RAS, the Inter-Departmental Ichthyological Commission, the International Society of Ecoethics, etc. The participants of the conference considered and discussed materials presented including presentations of scientists from Astrakhan, Vladivostok, Kishinev, Moscow, Sevastopol, and other regions of Russia and CIS, as well as colleagues from England, Spain, China, Germany, Singapore, the United States, and some other countries. International participants presented their reports as posters and sent them by mail. The presented posters reflected modern advances in hydrobiology, water ecology, limnology, biological oceanography, sciences on the biosphere and environment, and also the issues of education in biology and the conservation of nature. More than 50 communications were presented. Complimentary addresses for the participants of the conference arrived from the President of the Hydrobiological Society, Academician of the RAS, A.F. Alimov and Dr. Steven McCutcheon (Environmental Protection Agency, USA). In the Resolution it was pointed out that the participants of the conference consider the experience of such a meeting to be useful and are thankful to the organizers (the scientific team of Moscow State University), the Organizing Committee (including scientists of Moscow State University) and sponsors for their activities. The Chairman of the Organizing Committee and the Program Committee was D.Sci., S.A. Ostroumov. The Co- Chairmen of the Program Committee were Profs. Henri Dumont (Belgium), Otto Kinne (Germany), J. Widdows (Great Britain), and R. Wetzel (USA). A Resolution and the Recommendations of the Conference were accepted. A request was expressed to the Organizing Committee to forward the Recommendations to the RAS, the Russian Academy of Natural Sciences, and other interested institutions and persons. The Advisory Committee of the Conference comprised representatives of scientific institutions from Russia, Ukraine, Latvia, Estonia, Australia, Belgium, Brasilia, Germany, Netherlands, Egypt, Israel, Spain, China, Poland, Portugal, USA, Sweden, Switzerland, Japan, and other countries and included A.F. Alimov, V.L. Kasyanov, S.V. Kotelevtsev, E.A. Kriksunov, V.D. Romanenko, and G.S. Rozenberg (Russian Federation and Ukraine); Takashi Asaeda (Japan); M. Balode (Latvia); T.

Recommendations of the international poster session “Water Ecosystems and Organisms-4,” June 19, 2002 In carrying out scientific investigations it is necessary to pay attention to the following problems: —the role of water ecosystems in maintaining of stability in the biosphere, including stability of biological productivity, biogeochemical processes, and the heat regime of the biosphere and climate; —the treatment of chemical substances for ecology, especially sublethal effects of xenobiotics for water organisms; —problems that could result in the development of criteria to evaluate ecological treatment of anthropogenic effects and enhancement of the system of priorities when ranging the substances dependent on the degree of their threat for ecology; —problems of water self-purification; anthropogenic effects on organisms and processes that take part in water self-purification deserve more detailed investigations; —relationships between surface water ecosystems and subterranean waters.

The effect of selected edible preservatives, citric acid, sucrose and calcium chloride on the stability of C-phycocyanin (C-PC) at 0 5 8C and 35 5 8C was studied in aqueous solution. While screening the edible preservatives for a protein like C-phycocyanin, the denaturation of C-PC with urea as a denaturant and thermal unfolding studies through differential scanning calorimetry (DSC) was carried out to select a stabilizing agent having Hofmeister series behaviour acting on hydrophobic interactions. While studying the efficacy of edible preservatives, citric acid (4 mg/ml) was observed to be one of the best preservative for phycocyanin at 35 5 8C in aqueous solution for 45 days with negligible loss which is comparable to the stability of C-PC at 0 5 8C. Calcium chloride and sucrose were also found to be effective in maintaining the stability of C-PC in aqueous phase, but at lower temperature. Citric acid was able to maintain the stability even at higher temperature lasting for more than 1 month in aqueous solution. Citric acid C-phycocyanin Degradation DSC Preservative Stability
