ECOLOGICAL CONDITION OF IRIKLINSKY WATER STORAGE BASIN. ASSESSMENT OF FISH CATCH FOR THE LAST DECADE
DescriptionBrief physical-geographical, hydrological, hydrochemical and hydrobiological characteristics of Iriklinsky water storage basin, the largest water storage basin on the river Ural, is given in the article. Assessment of ecological condition of the basin, ichtyofauna and fish catch in for the last decade is casted. Recommendations on rational use of Iriklinsky water storage basin were given.

Description
The genotypic variability is submitted by a coefficient of variation, a genotypic diversification coverage - by a coefficient of heritability. Some attributes are recommended to the count in the Rapid Ecological Crop Trial (RECT). It is determined that pre-vegetation environment influenced on development of quantitative characters and the designed parameters.

ANAEROBIC BIODEGRADATION OF ORGANIC COMPOUNDS IN MICROBIAL FUEL CELLS
DescriptionМF-4SК membrane-based microbial fuel cell (MFC) was used for an anaerobic utilization of organic com-pounds of various liquid wastes. During incubation in short circuit mode, decreasing of the COD value on range 30-87 % depending on the type of wastes was detected. The dependence of the microbial fuel cell output power on the value of the external load was determined by a number of structural characteristics of MFC

Description
Puccinia triticina isolates from North Caucasus and Leningrad region were compared in regard to the genetic structure, phenotypic composition as well as frequency of occurrence of RAPD-phenotypes and polymorphous major fragments with the help of Rogers index. Did not demonstrate any significant differences according to their genetic structure and occurrence of major fragments of DNA-polymorphism. The difference of isolates from given regions was determined with high degree of confidence according to the phenotypes of virulence and RAPD-phenotypes
