SPECIES COMPOSITION, DISTRIBUTION AND ABUNDANCE OF WATERFOWL ZHETYKOLSKOGO SHALKAR-LAKE REGION OF EAST ORENBURG (KEY ORNITHOLOGICAL TERRITORY OF RU-217, OB-002) ^{[№ 11 ' 2016]}
Wetlands in the region has long been known as a place for mass nesting and stopover for more than 50 species of waterfowl. In recent years, interest in the region has increased due to the worsening problems of the protection of the global flight routes and conservation of endangered species, because due to the increasing aridity of the territory of its waters gained value peculiar critical habitats and nodal points on the paths of migratory flows waterfowl extensive the Middle Region of Northern Eurasia. The paper summarizes the literature, departmental and personal material on the dynamics of species composition, the nature of the host, distribution and abundance of waterfowl in the region in recent decades, which can be used in the development of a set of measures aimed at optimizing the use of bio-resources of the region and the preservation of its biodiversity.

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.

ECOLOGICAL AND GEOGRAPHICAL FEATURES OF THE SHREW SPREAD (INSECTIVORA, EULIPOTYPHLA, SORICIDAE) IN THE URAL-CASPIAN REGION ^{[№ 7 ' 2016]}
Zemleroykovye are one of the most ancient and, in too time, the prospering group of mammals. In the region dwelling of 10 types from which 4 look are krayearealny, noted only in several points where their modern stay demands confirmation is so far established. Specification also distribution demands kutor which area was significantly reduced in connection with anthropogenous transformation of habitats. Speschanny deserts have connected distribution of a skewbald putorak. From other representatives modern conditions are rather favorable only for evritopny, with universal ecomorphological type of the organization of the ordinary common shrew and tightly specialized small common shrew inhabiting ecoton communities. Rasprostraneniye and small белозубок even in general remains belobryukhy insufficiently studied and on a considerable part of the region it is only possible to speak about their distribution presumably. Specifications demand also biotopical preferences of these types. Everything noted complicates monitoring of this important group in the tsenotichesky relation and, respectively, development of recommendations about preservation of this interesting link in a region biodiversity.

SOME EKOLOGO-GEOGRAPHICAL FEATURES OF DYNAMICS OF DISTRIBUTION AND NUMBER THE EZHINYKH (INSECTIVORA, EULIPOTYPHLA, ERINACEIDAE) IN URALO-KASPIYSK THE REGION ^{[№ 3 ' 2016]}
Ezhinye are the most archaic mammals that gives the grounds to consider them as especially vulnerable group. At the same time in a number of habitats they are quite usual types that testifies о their considerable ecological potential. According to literary data and personal materials in the region lives 3 quite well genetically, ecologically and topichesk of the hedgehogs isolated a look. Their modern distribution and number are defined by landscape and climatic features and economic development of the territory. Most negatively last affects distribution of the southern hedgehog, especially at the southern limits of his area. For a big-eared hedgehog the happening changes on the most part of the region (especially at northern limits of distribution) were favorable; they favor also to expansion of an ecological niche of a dlinnoigly look. A necessary condition of their preservation is reduction of scales of anthropogenous impact on landscapes.

CURRENT STATUS OF RESERVOIRS SHALKAR-LAKE DISTRICT GETICONIMAGE (IBAS EN-217, REV-002) AND THEIR ROLE IN THE REPRODUCTION OF ANSERIFORMES ^{[№ 10 ' 2015]}
The reservoirs of the Orenburg TRANS-Urals and adjacent territories of Kazakhstan known as the place of mass nesting and migratory stopover mass hunting, as well as rare and endangered species of Anseriformes broad Median region of Northern Eurasia. Now they are considered as a kind of critical habitats and key points on the path of migratory flows and a whole range of other waterbirds. However, they are extremely unstable hydrological regime and, as a consequence, significant changes in avifauna. All this urgently demands a constant monitoring of their condition and population dynamics of species inhabiting them. The paper summarizes literary information, departmental and personal collected by standard methods over the last two decades, the materials on the change of state lands, dynamics of distribution and abundance in plant communities and important socio-economic species after the maximum level of water bodies and subsequent reduce the water content site. The research has allowed to develop a typological classification of water bodies, which together form a unique complex Supplement each other land, which all the necessary conditions for vital activity of 16 species of nesting geese. Conducted in different years and seasons of censuses provide an opportunity to roughly estimate the state of the local populations of swans, grey geese, dabbling and diving ducks, to determine trends in their abundance at each reservoir that will allow to develop a rational set of necessary biotechnological and environmental measures.

EKOLOGICHESKAYA CHARACTERISTICS OF WATER QUALITY IN MAJOR LAKES OF THE FAR EAST DISTRICT OF THE ORENBURG REGION ^{[№ 9 ' 2015]}
Accumulation of chemical elements and their receipt in objects of environment are result of industrial and agricultural activity of the person. At the same time, the significant role in pollution of environments is rendered by natural factors, especially in places of concentration of deposits of mineral resources, in particular copper колчедановых, nickel ores. Studying of the quantitative content of harmful chemical impurity in water objects, in particular in the territory of the Svetlinsky region of the Orenburg region having deficiency in fresh water wasn't carried out in connection with a lack of ecological information on an assessment of a surface water of the main lakes of the area, otsutstvy long-term plans of their use in the production, economic and household and recreational purposes earlier. For the solution of this problem authors conducted hydrochemical research of waters of the main lakes of the Svetlinsky region of the Orenburg region in 2010 and 2015, the analysis of the received results is made and the ecological assessment of these water resources is for the first time given. In article the arisen reasons (natural and anthropogenous factors) having negative impact on qualitative composition of lake water are also considered. Water resources of the Svetlinsky region of the Orenburg region include, first of all a network of drainless lakes of the large, average and small size. Are most significant lakes: Shalkar-Ega-Kara, Zhetykol, Obalykol, Kayrankol. These and other lakes are of special value for the nesting and flying natatorial  — swans, geese, ducks and other representatives of aviafauna. Hydrochemical indicators of quality of lake waters according to the content of sulfates, chlorides, ammoniyny nitrogen, oil products and other substances exceed the maximum-permissible concentration (MPC). The majority of lakes in adverse weather conditions (2013—2014) completely or partially dried up that testifies to need of carrying out on them environmental monitoring.

EKOLOGO-GEOGRAFICHESKIE ASPECTS OF DISTRIBUTION OF INSECTIVOROUS MAMMALS TO URALO-KASPIYSKOM REGION ^{[№ 6 ' 2015]}
For the unique territory of the Uralo-Kaspiysky region in the landscape and biogeographical relation now special relevance the problem of studying of reactions got it the most archaic insectivorous on escalating influence of a versatile economic complex. Thus paramount value the problem of inventory of fauna assuming the solution of the following tasks — studying of specific structure of group in general on the region and its structural components gets, specification of qualitative and quantitative structure of various ecological groups and the faunogeneticheskikh of complexes, identification of outlines of their areas, especially on borders of biomes where pass the major biogeographical boundaries. It will allow to adjust monitoring of structure of fauna and to develop system of actions for preservation of a biodiversity. The analysis of literary data and personal materials the ezhinykh, mole and the zemleroykovykh allowed to establish dwelling in the region of 15 types. From them 4 look (26,6 %) belong to European, 5 (33,3 %) — palaearctic and 6 (40,0 %) to Asian faunogenetichesky complexes. In the ecological plan 2 look are semi-water, 2 — typical geofila, 3 — the land running forms and 8 — gerpetofilam. Landscape and climatic features of the territory and specifics of ecology of types determined nature of their distribution in general by the region and its parts. In forest-steppe, steppe and semidesertic zones it is known on 10, in desert 11 types, носостав them significantly differs. The number of representatives European and palaearctic complexes in process of advance to the South gradually decreases, the area of the habitats occupied by them is reduced, there is a fragmentation of areas, and at the southern limits they meet only locally. At representatives of Asian faunistic complexes the opposite tendency is observed.
