✦ Synopsis

In memoriam Prof. A. G. RODINA On May 30, 1966, Professor A. G. RODIKA, one of the outstanding workers in the field of microbiology and hydrobiology, died in Leningrad. A. G. RODINA was born on March 24, 1901, in the town of Borovitchy. I n 1924 she graduated from the Leningrad University where she studied microbiology under Prof. B. L. ISACHENKO. From 1924 to 1934 A. G. RODINA worked in the State Hydrological Institute. This period of RODINA'S scientific work was devoted mainly to investigations of the microbiology of lakes. From 1937 until her last days she worked in the Hydrobiological Department of the Zoological Institute of the USSR Academy of Sciences. Here she started research work on the biological productivity of water bodies, developing a microbiological approach to these problems. Her motto was: "Microbiology is an organic link of hydrobiological research". With this aim in view she widely used and popularized the method of ultrafiltration and direct acounts of bacteria. She compiled tables of direct count data expressed as weight units, and started the study of aquatic biocoenoses using a method of their graphic representation. The investigations were undertaken by her on the Onega and Baikal lakes, on the Neva, Oka, Kuban, and Venta rivers, and in ponds and hot springs. I n 1937-1951 A.G. RODIXA studied the role of bacteria and yeasts in the feeding of aquatic animals, demonstrating their value and the role of bacteria in trophic chains. To A. G. RODINA belongs the priority in establishing the various nutritive values of bacteria. She revised PUTTER'S theory of osmo-
