Description
Simulation models are designed to reflect the cause-effect relationships between epizootic situation tensity for bovine leucosis and technogenic & radiation factors of environmental pollution. Zoning of Chelyabinsk region in terms of epizootic risk of bovine leucosis was carried out

DEVELOPING OF THE METHODOLOGY FOR THE IDENTIFICATION OF PICEA ABIES L. CLONES BY USING ISSR MARKERS
DescriptionThe technology for the identification of Picea abies L. clones by using ISSR markers was developed. 9 ISSR primers ((GA)9T; (AC)8C; (CA)6RY; (CA)6RG; (CA)6(GT); (CA)6(AC); (AG)8T; (GA)8С и (AG)8YT) were recommended to use for genotypes detection. The selected primers have shown the high level of polymorphism. A total of 172 amplified fragments were found by the selected primers and 149 (86.6%) of them were polymorphic

Description
We investigated the basic soil types (brown, brown wood) of foothill zone of Dagestan. We revealed that the distribution of nickel, chromium and lead in the soils depends on several factors: soil-forming rock, physical clay, humus and pH. We defined the background content of heavy metals in the studied soils of the region

Description
The article deals with the historical aspect of the formation of microbial-plant relationships. We study the details of the way the separate form components of the system "Microorganisms-plant" in the course of evolution. The research is based on the historical analysis of the interactions between microorganisms and plants. As a result of interactions a microbial-plant complex is formed. The article describes some types of interactions between microorganisms and plants. In general, various forms of symbiosis are components of a single evolutionary continuum

CURRENT STATUS AND PROSPECTS OF MANAGEMENT IN AGRARIAN SECTOR THE STAVROPOL REGION
DescriptionCurrently, when solving the problem of greening it is addressed to the technical and technological capabilities. These means can achieve some improvement of the environment in a particular region, but they are not enough to solve the problem of pollution in the whole country and the world. The problem in general can be solved only through an integrated analysis of the set of economic and ecological processes, which makes it possible not only to improve the development, but also to manage the process of impacts on the environment itself

Description
In herbaceous communities of annual crops dominate clean sowings, which are characterized by high productivity. However, it is very poorly adapted, different weak transformation of matter and energy and stronger exposed to stressful situations as compared to natural systems. In agroecosystems only structural diversity can supporting many processes on a much aligned level. In agrolandscape system creates mixed sowings that are practiced in forage production of many areas. Great importance is the selection of crops for joint sowing because the relationship of species in created systems are poorly investigated and documented in the literature is not enough. Investigations were carried out on experimental plots on the farm called "Zavety Ilyicha" of the Leningrad district and training farm called "Kuban" in Krasnodar. Formation of joint sowings in different moistening conditions, level of fertility, chemical and physical condition of the soil is a very big problem. Cultivation of different cultures in joint sowings significantly influences the terms the onset of main phases of vegetation in certain species. For example, the placement of sorghum between rows of soybean noticeably extended the period of its vegetation (5-7 days); acceleration of interphase periods was marked for amaranth; height of plant noticeably was changed, leaf area was varied, indicator of competitive features of individual species was differed. The existence of the relationship between the method of sowing crops, their farming practices and composition of species and population of microflora, mesofauna of soil, yield of dry matter and grain was observed

Works of painters of past is the source of information of crop domestication, use in horticultural, species diversity. Lagenaria crop images in painting can also be a resource for determining the morphological changes of the crop in evolution

Description
In the article we have studied the technology of obtaining a biomass of oil oxidizing microorganisms in a nutrient medium containing vegetable oil as the sole source of carbon and energy. In vitro and in soil experiment we have confirmed the effectiveness of the resulting biomass at work on bioremediation of oil contaminated sites. It is shown that the use of vegetable oil during culturing allows obtaining the same amount of biomass and carbohydrate raw materials, but the efficiency of its use is 20% higher, in average

BIOLOGICAL FEATURES OF THE CHINESE DATE (UNABA) IN WESTERN CISCAUCASIA
DescriptionThe article presents the results of the researches of growth and fructification of grades and forms of the Chinese date (unaba) in the Prikubansky zone of fruit growing. The biological features of the varieties and forms of unaba which are selected during researches on a research field of Kuban state agrarian university in the Prikubansky zone of fruit growing are considered. Novelty of work – such researches were conducted in Kuban for the first time

VARIETY OF LEGUMES IN NATURAL COMMUNITIES OF THE YAKUT BOTANICAL GARDEN
DescriptionThe article provides the information about the species diversity of the family Fabaceae in the natural area of the Yakut botanical garden. It also provides the information about the method and the study area, a description of the ambient phytocenotic, taxonomic analysis, areal analysis, bio-morphological analysis (the variety of life forms) given by K. Raunkier, rhythm analysis, environmental analysis (by A.P. Schennikov), analysis of phytocoenotic. We have also provided a summary of the endemics of Central Yakutia - Thermopsis lanceolata R. Br. subsp. jacutica (Czefr.)
