VEGETATION AND PLANT MATTER OF RAISED BOGS IN FOREST-STEPPE ZONE IN THE SOUTH OF WESTERN SIBERIA [№ 3 ' 2017]
The forest-steppe zone within the Novosibirsk region of Western Siberia was surveyed. The following typical mire ecosystems in close contact with each other are functioning: oligotrophic pine-dwarf shrub-Sphagnum raised bogs (ryams), reed floodplains and mesotrophic fens around secondary lakes in ryams. Calculation of the productive parameters of the pine stand was calculated using young model trees. Photosynthesizing mass of pine trees was 120g/m2, above-ground lignified organs— 344g/m2 with trunks contributed of 66%, and the trunk stock under the moss cover was 64g/m2. The stock of dead branches was 19g/m2. The total stock of above-ground mass of trees was estimated as 464g/m2, with contribution of pine trees in the total aboveground phytomass of 36% in ryams. Pine primary production was calculated as the sum of the current year needles and shoots and reached 47g/m2 a year, ie 14% of the total aboveground production in the ryam. In all types of mire ecosystems the phytomass, mortmass and net primary production were evaluated. Stocks of aboveground biomass varied from300 to 2,200g/m2, below-ground phytomass— from1,200 to 4,200g/m2. Net primary production varied from500 to 3,000g/m2 a year, minimal production is produced in oligotrophic ryams, and maximal production is produced in mesotrophic and eutrophic mires. Phytomass stocks and production were estimated for dwarf-shrub, grass and moss layers. Value of standing crop is similar in the studied ecosystems and estimated as 4,133g/m2 in fens, 4,032g/m2 in floodplains, and 3,681g/m2 in the ryam.

SOME ECOLOGICAL AND GEOGRAPHICAL FEATURES OF THE DYNAMICS OF THE COMPOSITION AND ABUNDANCE OF WATERFOWL EAST ORENBURG (KEY ORNITHOLOGICAL TERRITORY OF RU-217, OB-002) [№ 10 ' 2016]
Reservoirs East Orenburg are nesting and staging numerous waterfowl on an important migration route for the transcontinental Northern Eurasia. It found 56 species stay of 6 units, of which 3 (5.3%) are considered as vagrants, 15 (26.8%) occurred during seasonal migrations, for 36 (64.3%) species are known meeting in breeding season nature and stay two (3.6%) is not set. The article summarizes the literature, departmental and personal materials to change the species composition, the nature of the host, distribution and abundance of waterfowl in the region over the past two decades. This information can be the basis for developing a set of measures aimed at optimizing the use of bio-resources area and the preservation of its biodiversity.

PRACTICE-ORIENTED ASPECTS OF ENDURANCE AMONG STUDENTS AT PHYSICAL CULTURE LESSONS DIFFERENT SPECIES ORIENTATION [№ 7 ' 2016]
In any activity there are specific requirements to abilities of the person a long time to perform the work without compromising its efficiency, resist fatigue, effectively to recover after work. This ability is identified as one of the leading physical qualities— endurance. A sufficient level of development of endurance allows each person to better cope with any prolonged work (whether work training, mental or physical). That is why in all curricula in physical education on all educational levels education endurance is very important, provides a basic level of development. Educational practice in higher education has shown that most students experience some difficulties in the implementation of the control requirements for assessing the level of development of endurance. This determined the search areas of the ways to improve indicators of endurance among students at physical culture lessons. In our study, we considered the practice-oriented aspects of endurance, substantiate and verify the effectiveness of pedagogical conditions aimed at improving General endurance of the students at the lessons of physical culture of different species orientation.

ENVIRONMENTAL ASSESSMENT TRANSPORT INFRASTRUCTURE IN FACTOR NOISE POLLUTION ON THE EXAMPLE OF ORENBURG [№ 10 ' 2015]
In article features of noise as physical factor of environmental pollution, namely, atmospheric air are considered. Its influence on mental and physical health and efficiency of the person is described. In article it is allocated as the main source of noise for research— a transport stream as makes more than a half of all noise pollution and is available to carrying out measurements. For measurements of noise level the choice of the territory of the central region of the city of Orenburg— the most crowded part of the city with a set of places for a recreation and a dense transport network is reasonable. The purpose of work is drawing up the noise card and identification of zones with excess and observance of standards of maximum permissible noise level. For drawing up the noise card the audio-noise meter of the second class of accuracy by which 280measurements on 23city streets were carried out was used: along transport roads, adjacent buildings, recreation areas, the inhabited yards. The measurement technique is given in compliance by methodical indications of determination of the noise level created by a transport stream the choice of the measured size is reasoned. Data of maximum-permissible noise level of the normalized size for the studied objects are provided. The noise card is created with use of geoiformatsionny ArcGIS10.3 system and made without a housing estate. All measured indicators are given in the card in average value during measurement of March, 2015. On a total conclusions are drawn on the general noise pollution of the central region, the reasons for the developed adverse situation in respect of noise pollution on streets with the maximum excess of admissible noise level are described. In work the lowered noise level on the weekend is also reasonable and shielding of noise along highways is considered by green plantings.
