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 120šg/m2, above-ground lignified organsš— 344šg/m2 with trunks contributed of 66š%, and the trunk stock under the moss cover was 64šg/m2. The stock of dead branches was 19šg/m2. The total stock of above-ground mass of trees was estimated as 464šg/m2, with contribution of pine trees in the total aboveground phytomass of 36š% in ryams. Pine primary production was calculated as the sum of the current year needles and shoots and reached 47šg/m2 a year, ie 14š% 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 fromš300 to 2,200šg/m2, below-ground phytomassš— fromš1,200 to 4,200šg/m2. Net primary production varied fromš500 to 3,000šg/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 4,133šg/m2 in fens, 4,032šg/m2 in floodplains, and 3,681šg/m2 in the ryam.

Pankratovich T.M., Mikheeva T.M., Pankratovich Y.G., Stepanov V.M. 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 qualitiesš— 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.
