FEATURES OF DEVELOPMENT OF NATURAL SISTEMS AND AGRICULTURAL LANDSCAPES OF THE WESTERN AZOV
Description
We know, that in the development of the natural ecosystems of the Western Priazovye its biomass predominates. This ensures the maximum protection from noticeable changes of habitat. Basic succession defining a significant shift of energy flow in the direction to increase of their expenditures to maintain forming populations determined by broad specialization of natural systems on ecological niches, and their individuals have rather small size, the life cycles of many of them are very simple and short. The coastal strip of the Azov Sea has been seriously degraded due to powerful recreational load, especially in the summer. Presumably one should expect an increased anthropogenic load on ecosystems of this area. Quite obvious is a regularity of overload agroecosystem which occupies the territory between the river and other water formations. The relatively low productivity of agricultural systems of the Eastern Azov is limited by number of factors, among which the main place is occupied with the moisture, nutrients and high weediness of sown areas

FEATURES OF THE EVOLUTIONARY DEVEL-OPMENT OF LIFE FORMS OF HIGHER PLANTS
Description
Climatic cycles associated with global phases of create gasses are the reasons of oscillation ecosystems and their constituent. Ecological capacitance of systems increases or decreases due to the appearance of new ecological niches, which creating favorable conditions for expanding or narrowing opportunities of adapting new types of organization of living organisms and their significant changes. Conjugacy of the biological evolution of living organisms with geological crises and periodic variations in solar activity is observed. Direction in the development of plant life forms since the beginning of their occurrence was quite varied. The most deeply the development of life forms was developed for flowering plants, starting from of different groups of gymnosperms. The main reasons for selection of life forms are due to challenges facing researchers

Description
The analysis of the variability dynamics of recombination frequency in the population of splitting F2 interspecific and intraspecific tomato hybrids has been carries out. It was discovered that recombination frequency depends on the components of cross breeding. It has been established that it is reasonable to use mutant forms of Мо 393, Мо 628 and interspecific hybrid F1 Мо 628 × L. esculentum var. racemigerum in selection process as an inductor of genotypic variability

SIMULATION OF EARTH'S POLES DYNAMICS USING ASK-ANALYSIS
Description
Based on local semantic information models, we have examined the dependence of the dynamics of the displacement of the pole positions of celestial objects. We have also developed and differentiated an analysis of ASK-pole modeling of dynamics within sixty-year cycles of reference points and substantiated reasons for the population inversion and singular states in the dynamics of the pole
