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 BASIS OF FUNCTIONING OF MIXED SOWINGS
06.00.00 Agricultural sciences
DescriptionCreation of joint sowings is very complicated modern environmental problem and the solution is impossible without a comprehensive study of the relationship between individuals of different species that are emerging at the level of a plant community. Studying biotic relationships between taxa used in these crops is very important; joint crops include combinations (sowing crops in rows) and mixed crops (crop seeds mixed and sown together); great attention in the mixed and combined sowings has been paid to selection and combination of cultures

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

ECOGEL IS THE NEWEST COMPLEX OF WATER SUPPLY FOR FRUIT PLANTS
06.00.00 Agricultural sciences
DescriptionFrom 2011 to 2015 in the laboratory conditions there were studied the physical properties of absorbents in the controlled environment. There was defined that in the variant of the "soil+water" the usual colloidal mass is formed and in variants "soil+absorbents+water" - a mixture of soil and gel. There was determined that the least diurnal evaporation was fixed at the use of the mixture: soil+ preparation “Ecogel-1”. In the control variant of the experiment the full water evaporation was marked on 31st day after beginning of the experiment, in the variant with the use of the absorbent Aqua Life the whole water evaporated on 48th day, and at the use of preparations Ecogel-1 and Ecogel-2 the duration of evaporation of the same amount of water supply at temperature 22-24оС and air moisture in 55-60% continued 57-65 days. In the result of five-year laboratory researches there was determined the possibility of development of water-saving technology for fruit plantations. When we used absorbents (granules, powders) in planting process and watering resulting the gel-like mass completely collapses the root system of fruit plants and the operation of the system "soil-roots-leaves" will not depend on the physical condition of soil and environment due to water consumption for transpiration

EVOLUTIONARY THEORY: THE SEARCH FOR NEW PARADIGMS
DescriptionThe article is devoted to the study of contemporary models of evolution based on new scientific discoveries. Integrative and systems approaches in the study of evolution that take into account deficiencies of “modern evolutionary synthesis” are systemized. Work also considers the directions and interdisciplinary perspectives of development of the “new evolutional synthesis”

SPECIAL CASES OF INVERSE MATRICES
01.00.00 Physical-mathematical sciences
DescriptionThe inverse matrix for the square matrix A of order n with coefficients of some field exists, as it is known then and only then, when its determinant is not equal to zero. If the matrix A has a certain type (certain structure), then an inverse matrix A-1 should not have exactly the same structure. Therefore, it is interesting to describe such square matrices A, which have an inverse matrix A-1, having the same structure as the matrix A, under certain conditions. For example, a subdiagonal matrix with nonzero elements on the main diagonal has an inverse matrix over a field of characteristic zero, having also the form of subdiagonal matrix. Similarly, an inverse matrix towards symmetrical or skew-symmetric matrix is also symmetric or skew-symmetric accordingly. Also, the matrix inverse to non-degenerate (nonsingular) circulant will be a circulant itself, and finally, the matrix inverse to nonsingular quasdiagonal matrix D will be quasdiagonal itself, and will have the same partitioned structure as D. Thus, there is a problem of determining these types of nonsingular matrices that have an inverse matrix of the same type as a given matrix. In line with this problem in the present study it is determined such type of matrices for which an inverse matrix has the same type, at that the conditions are identified in explicit form, ensuring the nonsingularity of the matrix. The matrices of three orders are shown in detail. These results allow determining the characteristics of fields over which there are inverse matrices of the considered types

CYCLICAL EFFECTS OF ACTINOMYCIN D ON THE BARLEY COLEOPTILES GROWTH
DescriptionIn cell biology, actinomycin D is shown to have the ability to inhibit transcription. Actinomycin D does this by binding DNA at the transcription initiation complex and preventing elongation of RNA chain by RNA polymerase. When soaking the seeds in a solution of actinomycin D, antibiotic blocks RNA synthesis and seed germination occurs at the expense of long-living RNA, available in the mature seed. In the article we present experimental data indicating that as storage seeds of winter barley are changing the action actinomycin D on the growth of coleoptiles. It is shown that actinomycin D at a concentration of 40 µg/ml in October reduced the growth, in December it was not authentically, and in February it was paradoxical amplified growing coleoptiles. We suggest the part of the actinomycin D fastened with growth inhibitor coleoptiles, whose structure changes during seed storage and increase the affinity of actinomicyn D to the inhibitors. At a concentration of 60 µg/ml actinomycin D effectively reduced of the coleoptiles growth. Suppression of seedlings roots growth was proportional to the concentration of the actinomycin D and exposure time
