THE ABILITY OF TTRAMA OF TRUE POLYPORE (FOMES FOMENTARIUS FR.) TO OIL SORPTION [№ 12 ' 2017]
Oil and oil products are among the most toxic environmental pollutants. There is a wide range of substances with necesarului ability, which include mineral and organic sorbents. The use of organic sorbents are more environmentally friendly due to their genesis; as the sorbents are oil-impregnated they can be used as fuel. Search and evaluation of new organic sorbents is an actual problem of ecology. The ability of the oil sorbing by trama of basidioms of Fomes fomentarius Fr. was studied. This species is a cosmopolitan widespread in many regions of the world and occurring on dead wood and weakened trees of many genera of deciduous trees. In the experiment were used 3 canisters filled with distilled water containing oil products with a concentration of 5, 10 and 15 %. In each canister was dropped segments of fruiting bodies with a thickness of 1, 1.5 and 2 cm were dropped. For 3, 7 and 10 day of the experiment, there was a steady absorption of oil in each of the samples. As the saturation of oil, the segments were immersed to the bottom. The saturation of oil products was uneven and depended on the thickness of the sorbent and the concentration of oil. In parallel with adsorption, there was a gradual separation of the oil to fractions in all three cans, accompanied by the formation of mycogenic protein-mat. It can be concluded that the tissue of a fruit body of polypore present effectively oil absorbtion; the fungi has a pronounced catalytic activity, which leads to the decomposition of the oil to the fractions. The most efficient thickness of the oil — sorbent was 1.5 cm.

BIOTECHNICAL MEASURES TO MAINTAIN THE POPULATION DENSITY OF THE SIBERIAN ROE DEER (CAPREOLUS PYGARGUS) ON THE TERRITORY OF THE ORENBURG REGION [№ 8 ' 2017]
Biotechnical measures, or measures to protect and improve animal habitats Wednesday, planned and executed with the purpose of impact on population density and placement on the territory of the Orenburg region of individual species or groups of animals, as well as maintain or increase biodiversity of animals. In modern conditions of optimal density is animals, providing an environmentally and economically acceptable ratio between the different components of natural communities. Factors that characterize the capacity of land for a particular species, are their feed and protective properties, mutual spatial combination of these conditions, as well as the presence of competitors and enemies. Specific impact on the capacity of the land have climate and human activities. The optimal size is determined by: in terms of quality; as winter forage capacity; based on comparative (expert) evaluations. Way to establish the optimum number of quality in terms of the land can be recommended as the primary method of counting numbers. This method gives the most reliable indicators through comprehensive assessment factors Wednesday. Determination of optimum number this way includes the following stages: selecting the types of habitats and their inventory; environmental assessment types of habitats; bonitirovku territory; calculation of the optimum number of species.

DISTRIBUTION AND ECOLOGY OF PHYTOPATHOGENIC WOOD-DESTROYING BASIDIOMYCETES OF THE SOUTHERN PREURALS [№ 9 ' 2014]
Southern Preurals features a low percentage of forest that defines a focus on forests in the region. One of the factors that determine the dynamics of forest stands are phytopathogenic basidial fungi. The article presents data on the species composition and the spatial distribution of phytopathogenic basidiomycetes at the Southern Preurals. Discusses the variation in the degree of contamination of forest stands by phytopathogenic species depending on forest type and in the latitudinal gradient. The decline in the share of plant pathogenic species in the latitudinal gradient in the transition of the forest-steppe by steppe zone is marked, which testifies to the increasing of time of conservation of elements in wood.

COMPREHENSIVE ASSESSMENT OF ARTIFICIAL PINE TREE STANDS IN THE ORENBURG PREURALS [№ 10 ' 2013]
The results of the comprehensive assessment of artificial pine tree stands in the South Ural steppe zone (Novosergievskyi district of the Orenburg region) with the use of geobotanical indices, the vitality of forest stands, the structure of wood-destroying fungi biota are given. Noted that high richness of fungi species is characteristic for plantations with high vitality. Discussed prospects of integrated assessment of forest stands with the use of these indicators, and made recommendations for conservation of the most valuable plantations.

ACCUMULATION OF HEAVY METALS IN THE SYSTEM "SOIL-TREE-FUNGUS" IN THE SOUTHERN PREURALS [№ 6 ' 2013]
The article presents the results of a study of the accumulation of zinc, copper, manganese, iron in the system "soil-tree-fungus" at the conditions of Southern Preurals. In the soil noted the high content of Fe, Mn, in birch wood — Mn, in the fruit bodies of Fomes fomentarius — Zn, Fe, Cu. In the system "soil-tree-fungus" noted increase in the quantity of zinc and copper. Indices of accumulation of fruit bodies of all heavy metals, in addition to copper, are quite low.
