BIOLOGICAL ACTIVITY OF URBAN SOILS (ON THE EXAMPLE OF ROSTOV-ON-DON)
DescriptionAbout 40 soil cuts were made in various parts of the city of Rostov-on-Don. The determinations of enzyme activity (catalase, invertase, polyphenoloxidase) were carried out in natural and antropogenic soils of a sub-urban park, residential and industrial areas of the city. The enzyme activity of soils in urban condition signif-icantly lowers than in non-urban soils. It is established, that significant impact on the biological activity has duration of sealing, and the longer the period, the higher the negative impact on the enzymes activity. However, a close relationship between humus state of soil and its enzyme activity kept in a condition of ur-ban pedogenesis. The high activity of investigated enzymes is typical to soil horizons which contain the highest amount of soil organic matter

ECOSYSTEM DEGRADATION OF THE LIMESTONE MASSIFS OF WESTERN CAUCASUS AFTER DEFORESTATION
DescriptionSignificant changes in mountain ecosystems occur after deforestation on limestone massifs of the Western Caucasus. Tall-mountain-meadow vegetation with a large variety of species formed at low and medium soil disturbance 3 years after logging. Physical and biological properties of calcareous soils also vary greatly. The values of biological activity decrease at the maximum load is more than 10 times. Biological activity is increased by 20-50% or more cutting stations with low disorders. Biological properties of soils (especially the enzymatic activity) are very sensitive indicators of changes that have occurred as a result of logging. Changes in the activity of soil hydrolases different from changing oxidase activity at different times after logging

Description
This work was carried out on the natural territories in the collection and of the Yakut botanical garden (JBG). The object of study was medicinal plants used in the treatment of cardio-vascular system. On the natural territories JBG we have noted 39 species of medicinal plants. 26 species were studied in a culture

Description
We studied the resistance of the eight strains of oil-destructive actinomycetes, isolated from the oil-contaminated ecosystems to heavy metal salts when cultivatiwng with different carbon sources. Furthermore we researched feasibility to use those microorganisms for bioremediation of oil- contaminated sites with high level of heavy metals

ANALYSIS OF TREE HIGHT GROWTH CURVE DEVIATION OF SCOTS PINE IN MINUSINSK PINE WOODS
DescriptionA deviation from tree height growth trends of Scots pine is analyzed. They have a periodicity and vary both by the amplitude and period. At average the value of period is 40-50 years and has a significant variabil-ity. It depends on longevity of tree life and age classes. The deviation depends on relation between the trees in stand. An abiotic factors effect increases and comes to the fore under constant of actual adverse environment conditions for growing

Description
The article presents a study on agro-biological and technological indicators of Don indigenous wine grapes in the conditions of the Anapa-Taman area of the viticulture of the Krasnodar region. It was found that the introduced varieties are consistent with the conditions of the area and can be recommended for growing in production plantations in southern Russia. On ripening, the varieties are as follows: the early ripening varieties are Sibirkovy; a group of middle-ripening - Aligote, Plechistik, Varyushkin; to the medium-late - Bessergenevsky 10 and Krasnostop Anapsky. Highest yield was proved to for such grape varieties as Bessergenevsky 10 (150 kg / ha) and Varyushkin (140 kg / ha). Test grapes of Aligoté and Krasnostop Anapsky showed an average yield of 120 and 130 kg / ha, respectively, red and Sibirkovy Plechistik - 140 and 135 kg / ha. Comparing the current literature with the results, we noted the following notable differences: all the studied indigenous wine grapes in the conditions of the Anapa-Taman area of the Krasnodar region matured earlier, had higher productivity indexes and gave higher yields, than in the conditions of their homeland Rostov region

ANALYSIS, OPTIMIZATION AND CORRECTION OF NUTRITIONAL STATUS OF ROAD-BICYCLISTS
DescriptionThe article analyzes the nutritional status of road-bicyclists and optimization of diets with use of com-puter modeling of quantitative parities of traditional food in view of feeding behavior of athletes. For cor-rection of a daily food allowance of sportsmen, the new drink of functional purpose is created

MODELS AND TABLES OF GROWTH OF ARTIFICIAL ORIGIN OAK FORESTS IN THE LOWER VOLGA REGION
DescriptionThe article discusses the function of growth for the simulation of forest indices of individual tree element of the forest. Algorithm calculate tables of growth based on materials by eye-measuring taxation on the basis of patterns of variability of the amount of Room space of sections of stands of oak is proposed. Tables of growth of stands of different density are developed
