Description
Qualitative and quantitative composition of the low-molecular carboxylic acids (CA) which were contained in the cultural liquid (CL) of the four strains of Escherichia coli and Salmonella enteritidis var.Issatchenko was investigated. The differences in the composition of the CA were shown, their dynamics during the bacterial growth and their total concentration in CL were strain specific characteristic. The differences in the composition and dynamics of the CA, which are specific only to probiotic and opportunistic strains were revealed

Description
The article demonstrates the taxation parameters of the pine plantations that was damaged by fire in 2010 in Suburban forestry of the Voronezh region and was calculated the basic ecological functions they performed before death. The intercommunication was found between increasing level of air pollution in the study areas and growing of heart and pulmonary morbidity of population

Description
The article gives the estimation of the influence of Agro industrial complex on the state of small water basins. Hidrochemical and microbiological researches of rivers at their main stages of water regime were conducted. Seasonal fluctuations of main polluting substances were revealed. For microbiological estimation of the water quality in investigated water basins, there was done the calculation of the total quality of microorganisms. At the same time, a quality control of sanitary demonstrative microorganisms was done

ECOLOGICAL PATH "CHOCHUR-MURAN" ON THE NATURAL TERRITОRY OF YAKUTSK BOTANICAL GARDEN
DescriptionThe article presents the data about flora and vegetation of the territory of the Yakut Botanical garden, where an ecological trail will be; there is a characteristic of plant communities and their classification. Preliminary, the flora of the ecological path includes 310 species of higher vascular plants belonging to 54 families and 172 genera

ECOLOGICAL BASES OF SIMBIOGENIC DEVELOPMENT OF PLANT AT COMPLEX SOWINGS
DescriptionDevelopment of plants in mixed or combined sowings is based on the symbiotic association in the basis of which we have decreased sexual process and its mechanism of genetic exchange among endosymbionts and stimulating of genetic exchange and expansion of the diversity of species among exosymbionts. The exception is the symbiosis of orchids and fungi - activators of orchids mycorrhiza with developed micellar system easily passing on saprophytic option. Coevolution of plant organisms with fungi indicates the specifics symbiogenic conjugate evolution, showing an example of the evolution of a small community with different contact with the external environment. The phenomenon of symbiogenesis has a long history and was manifested in a variety of different types of organisms. Today, some dependence of existence of one species from other organisms is observed at approximately 75% of higher plants and 90% of the animals in varying degrees of symbiogenic dependence from other species and taxa. Originality of symbiogenesis was analyzed by Academician A.A. Takhtadzhyan (1973) during its consideration of origin of eukaryotic cells as process of "assembly" of a complex system. Different approaches to determining the biological essence of symbiosis are known in the history of study of this phenomenon. On the whole phenomenon of symbiosis belongs to the category mutual relations of organisms of different phylogenetic groups

Description
The article presents the ecological characteristics of soil types and forest cover of the Red October forestry of the State Unitary Enterprise of the Republic of Adygea. We have defined their relationship and the division into groups of forestry and environmental values. A complex combination of bioclimatic factors, parent rocks and topography has led to a large diversity of soil cover. We have revealed that different soils have different degrees of erosion on sloping hillsides, ravines, and steep slopes are dominated by strongly eroded soils. The most common form of physical degradation of soils of the red October experienced forestry is seal root layer observed on heavily used areas and pastures. Also, we found that poorly structured soils containing little humus are prone to compaction. Methods of rooting out areas after clear cutting of forests lead to secondary soil degradation. It especially enhanced if, at the moment of stressing, the soil is in the waterlogged condition. Therefore, at reforestation we should use different reclamation processing. And this leads to the difficulty of their use in reforestation. It is established that intensive anthropogenic activity leads to degradation of soil and forest cover of the study area

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.

ECOLOGICAL AND BIOLOGICAL FEATURES OF GROWING OF OWN-ROOT PLANTING MATERIAL OF FEIJOA
DescriptionThe results of breeding of lignified cuttings of varieties and forms of Feijoa in the humid subtropical of Russia are presented. Lignified cuttings cut from the top and bottom were covered with uterine of root-own plant varieties of "Superba", "8-10""0-01"and "D-1" and placed on the beds with different substrates: tea soil; peat + sand, perlite. It is established, that the lignified cuttings from the bottom of the overgrown Feijoa variety “Superba” were better rooted in the "tea soil," from the top of the shoots - on the substrate peat + sand. Lignified cuttings of all forms and types of plants studied rooted worse in perlite

ECOLOGICAL-HYGIENIC ASPECTS OF THE RECREATIONAL ZONE OF THE KRASNODAR REGION
DescriptionThe anthropogenic interference plays more and more increasing role in modern ecologic paradigm. Adjusting this role to the studied region, it is defined by the socio-economic conditions being formed in our country. The rate of construction in the resort zones of the Krasnodar region is sweepingly rising. In spite of the high therapeutic-recreational capacity of the region, this tendency is leading to the further worsening of the ecological situation. The strengthening of the ecological control in the terms of the present economic crisis is highly urgent when more and more Russians prefer native resorts for their rest and in the first turn - resorts of the Krasnodar region. The condition of the ambient air of some recreation zones of the Krasnodar region has been studied. Methods of atomic-absorbing chromatography and optical emissive spectrometry have been used. It has been shown that the differences in data are mainly determined by the different content of the air impurities depending on the probe selection place. According to the studied data, the ecologically purest places are Krasnaya Polyana and Goryachy Klyuch. Whereas, the content of atmospheric air pollutants in the central districts of the resort towns of Sochi and Goryachy Klyuch exceeds MAC. The comparison of the obtained data with the same data of the city of Krasnodar that had been obtained before allows making a conclusion about the favorable eco-hygienic state of the resort zones of the Krasnodar region. So our investigations authentically prove the existence of the significant differences in the ecological conditions of the city on the one hand and of the resort zones of the Krasnodar region on the other hand
