MODERN WAYS OF OIL-CONTAMINATED WASTE UTILIZATION FOR THE ELIMINATION OF POLLUTION
DescriptionThe article deals with the problem of eliminating environmental pollution by oil-contaminated waste. It's suggested modern ways of improving technologies for oily waste utilization. The comparative characteristic of the essence, advantages and disadvantages, effectiveness of ways of waste recycling is described. The basic utilization technologies of oil sludge of various origins are emphasized taking into account the aspects of their composition and properties. It's represented the results of a patent search in this area to ensure a high level of new developments. It's characterized the developed technologies for utilization and recycling of oily waste to produce environmentally products of utilization – organic and mineral additives which are suitable for use as secondary material resources

THE CURRENT STATE OF PIKES IN YAKUTIA WATERS
DescriptionPike inhabits almost all the rivers of the Yakutia system. It is more widespread in the lakes of YanoIndigirka and Kolyma lowlands. Objective: To provide a modern assessment of fish in the main model reservoirs, create an ecological prognosis and the possibility of their use in modern conditions. Methods. The material was collected in the conditions of anthropogenic pollution. Full general biological analysis was conducted for the fish. Cruise studies were conducted covering the northern territories - r. Anabar, Olenek, Lena, Yana, Indigirka, Kolyma and Chrome, as well as Vilyuy Dam, from 1969 to 2016. We used the standard ichthyologic methods of selection and processing of the collected material. Results. Because of climate warming, there were reported pike approaches in the lower reaches of the river Lena, Yana and Kolyma. Maximum dimensions were noted earlier in the lower reaches of the river Lena, where the maximum weight of pike was 18 kg. The fecundity of 16-211 thousand eggs. It was revealed, that the catch was better for young pike. Conclusions. Stocks of pike are in satisfactory condition, and its reserves are proposed to be increased, at the expense of unused areas (lakes Kolymo- Indigirka lowland) up to 220 m. It is proposed as a fish-breeding facility in Yakutia reservoirs

CURRENT STATE OF THE COLLECTION OF MEDICINAL PLANTS OF THE YAKUTSK BOTANICAL GARDEN
DescriptionThe article considers data on the stocktaking of plants in the collection of medicinal plants of the Yakut Botanical Garden on the following parameters: the study of the component composition, the inclusion in the Pharmacopoeia articles and the Russian State Register of medicinal products. Introduction test in the collection has been performed for 158 species from 99 genera and 41 families, currently the collection has 101 species from 79 genera and 34 families. Chemical composition of plants is known for 61 species. 17 species are pharmacopoeal and 15 species make medicinal products available. The rest of the medicinal plants can be used in folk medicine. Most represented are Asteraceae family (25), Ranunculaceae (20), Rosaceae (16), Fabaceae (15), Lamiaceae (13), among tested plants. According to the assessment of introduction capabilities, 49 species in the collection are highly stable, 51 - stable and just one is unstable

DescriptionThe article is devoted to results of researching of lichens flora of Nakhchivan AR Azerbaijan. During 2003 - 2009 specific structure, regular structure, laws of distribution on high-rise zones, ecobiomorphe, geographical features of lichenflora, rare species of lichens and the problem of their preservation were studied. In the region, there are 347 species of flora, 6 variations and 5 forms of the lichens concerning 83 genus and 38 families are revealed. From them, 17 families, 35 genus and 138 species are noted for the first time for research territory. In the article the facts about ecomorphological features of 12 new kinds of lichens of Nahchivan АR are given

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

COMBINED PLANTING OF ANNUAL CROPS - IMPORTANT PROBLEM OF PRACTICAL ECOLOGY
DescriptionSelf-regulation of agricultural systems is based upon taking into account the interaction of their components released in variety of species and trophic relations; agricultural systems is diversified in towards a sustainable, productive and strategic development of the systems; one of the most promising areas of diversification of agricultural systems is considered to be an introduction to the practice of combining crops, known in agriculture for a long time, which shows us the nature. The most developed technology for creating combined crops is the practice of creating mixtures and the nature of the relationship between their different components

MULTI-LAYER COMPOST AS AN IMPORTANT SOURCE OF ENRICHMENT OF SOIL NUTRI-ENTS
DescriptionMulticomponent compost represents a good environment for a significant number of species of living organisms and populations which produce enzymes, vitamins and other active substances. Chemical and physical properties of complicated composts are heterogeneous and polydisperse interim systems, and on the gene pool of living organisms are a rich comprehensive substratum. The heterogeneity of complicated composts of characterized by a very wide range of organisms which using animal waste and isolating of germinating seeds and spores of higher and lower plants

COMPLEX COMPOST AND ECOLOGICAL NICHE OF LIVING ORGANISMS IN AGROLANDSCAPES
DescriptionEcological niche acts as an important evolutionary function of living organisms in the ecosystem and determines its properties, which are caused by the nutrient requirements, mobility, ability to reproduction, biochemical features, structural features limits tolerance to environmental conditions, opportunities performing certain actions in the specific biocenosis; in the process of divergence (species, their internal and external properties and abiotic characteristics) features of ecological niches are changed , there are new kinds of living organisms and, of course, the formation of new ecological niches
