Ecological aspects of "Eurasia" canal construction are considered here. The fact that can negatively affect natural area preservation (preserves, reserves), located in Kumo-Manych depression, along where the canal construction will take place, is shown in this article.

Having been defined the position of morality in the modern ecological space it was found that ecological crisis increases because of spirit crisis, education crisis and human crisis. Defining the different levels of human spirituality it is revealed that at the highest level the nature is perceived as a human value, a value just as for people living in it.

The authors of the article reveal trends of climatic conditions changing and variability of hydro-thermal conditions in semidesert landscapes of Northern Caucasus.

The article is devoted to the results assessment of the influence of droughty periods which lead to parching of different intensity of nonirrigated lawns of different types for the period from 20 to 90 days. Parched lawns lose their decorative power and ability to form the environment: temperature on their surface is 6-9ºC higher then on the irrigated lawns and wetness is 20-29% lower.

The kofficients of its rang carrelation the other flora types are calculated. There are made the conclustions about the influence of the nearly flora types according to the taxonomic composition of the Dagestan coastal lowland.

The article is dedicated to the searching of oil-pollutions’ influence for the variety and quantity of the sandy and mixed sandy soils of the “Izberbash” deposit field.

Uncontrolled industrial effluents into water bodies and the use of different types of herbicides and pesticides in agriculture has led to widespread pollution of fishery waters.

In article are presented results of the study of embryonic and maggot’s development of prawns Ralaemon elegans fished out from Shamkir and Mingechaur water reservoirs. There have studied of the reproductive possibility by specimen, as well as particularities of their feeding.

The paper presents the results of analysis of the state of Caspian sturgeon stocks in long-term aspect. The main factors causing the decline in the state of Caspian sturgeon stocks are considered. It is noted that at the present stage when natural resources of the Volga-Caspian basin have been actively developed by man such factors as human impact and geopolitical changes in the region arise in the general succession of negative factors. It is shown that measures aimed at restoration of these valuable fish populations do not fully solve the problem.

Researches made by us have shown that 40 species of vermin and 16 species of predators play significant role in regulation of the quantity of 13 most harmful insects which inhabit in forest massive and fruit tree gardens of Lenkoran region of Azerbaijan. In general 56 species of entomophages which are related to the order of hymenopterans, neuropteras, coleopteras and dipteras. Their host significance in regulation of the quantity of hosts was identified.

The paper contains information about the origin and distribution of feral horses in different continents. The data on population dynamics and behavior of these animals in biosphere reserve “Rostovsky” are discussed. The article presents the factors which limit feral horse livestock.

In this article are regarded the problems of biology and ecology of Nycterentes procionoides in the Hamamaurtovsky reserve of Republic of Dagestan, which was acclimatized in the indicated reserve in the 1934.

The article is the first to present information on the ecological peculiarities of habitation for the fish rotan in Kuybyshev water reservoir; its morphometric characteristic, age and sex structure, terms of spawning, prolificacy, feeding, morphological deviations; and also on presence of heavy metals, toxic elements and radioactive nuclides.

The author of the article proves the topicality the ecologic and biologic research end biocoenotic relations of helminthes and their hosts.

There were isolated 124 kinds of bacteria related to genus Enterobacteria, kind of Enterobacter. These isolated kinds were researched for having some facts of pathogenicity hemaglutinating ability as by D-mannosy, as by its absence, hematlogic ability, resistance to antibacterial prepirations. As a resalt were apparented that the more of strains have got traitsof pathogenisity and multiple resistance to antibiotics.

The considered possibility of the use yeast Saccharomyces cerevisiae as suitable test-object, allowing define the quality of water and her its solution. Certain need of the biological testing in ecological monitoring.

The physical and chemical processes proceeding in soils polluted hydrocarbons of oil are described. The biological method of clearing and restoration ecological functions of the petropolluted soils, based on an intensification of processes of biodegradation of hydrocarbons of oil, at the expense of creation of optimum conditions of ability to live native carbon oxidizing microflorae is considered.

In the article features cjmposting of organic materials are considered at use of a traditional way and fermenting additives. Indicators of quality of the composts received with the use of dairy whey and a bacterial preparation as the fermenting additive are investigated. Comparison of the received samples of composts on such indicators of quality as is spent: humidity, acidity, the maintenance of organic substance in recalculation on dry weight, quantity of the general and fmmonium nitrogen.

They are considered natural and anthropogenic factors degradation and опустынивания Kizlyar pasture and measures upon their improvement.

Estimation of the adaptive potential natural phytocenosis is given to soil salinization ground under natural moistening. The Studied general regularities of the operation to pasture vegetation and condition of the renewing the vegetable cover on techno-broken ground (the lands). The analysed role prevail plants in conservation balances conditions pasture.

Influence of salinity stress on the morphological features of durum wheat in different phases of vegetation is studied in the work. It is revealed that in earlier phases the samples have weak stability, but further salt-stability increases.

165 persons suffering chronic generalized parodontitis (CGP) are surveyed. The medical course irrigation parodontits with mineral water has had positive influence on level of concentration of streptococcal and staphylococcal micro flora in parodontits pockets.

Oncological disease of the population living in areas of the Astrakhan region with various level of pollution of atmospheric air was investigated. Statistical validity of dependence between quantity of average annual emissions of polluting substances in atmospheric air of the Astrakhan region and oncological disease was found out on. Correlation coefficient was 0,595.
