The problem of socio-ecological reality origins is considered. Being formed as an integral system, socio-ecological reality suggests multi-dimentional interaction of society and nature when the former is viewed as a sociomorphic organism expressed in such phenomena as home and road. Home is regarded as a collective image converging a special source for «settled» structuring of socioecological reality, while road converging the latter’s «nomadic» structuring.

The researches combining a social, economic and ecological content, find out a generality of appendix area and global purpose. This purpose image is hidden behind the term sustainable development". These restrictions are presented as the multiplicative index of the development. This index is reflecting an information balance of a territory.The level of the Caspian Sea, the largest inland sea in the world, has fluctuated capriciously in history, with amplitudes up to 3 m in the last century, to 25m in the last millennium, and to over 150m since the Last Glacial. The results suggest that the last major highstands occurred around 2600 BP and in the Little Ice Age and coincide with global cooling events associated with minima in solar activity. This suggests that millennial precipitation changes in the Volga River drainage basin are also forced by solar activity.

It is shown that after Uf-processing of water jointly with with hlorsoderzhashchi бактерицидами and silver ions (or copper) occur increase antibakterial'noy stability of water as at rather low, and high
temperatures. The decline of dose is thus possible ecologically dangerous chlorine.

The data of intrapopulation variability of caucasian endemic Rosa oxyodon Boiss. are given in the article on the base of the complex of quantitative indications of the bush and biometric factors of the leaf.

Species’ variety of ephitipical lichens in different kinds of man-made plants of forests’ ecosistems in steppe zone of south Russia is represented at the article. The dinamic of appearence of ephitipical lichens at the different stadies of forest’s development was watched. On the base on found speciesindificators the works were held in Novocherkassk, Rostov district.

Regarded, that the plants‘s cover in Daghestan is well studied. However, flora in some regions, such as Gimrinskiy and Salatau chains are not investigated completely. The aim of analyses of flora is revealing and comparatively appraising the flora indicators, focusing on their systematic geographical, ecological and other characteristics.

The author of the article describes special features of the recovery of different botanical groups, plants which grow at sand soil, depending on morphological anatomical features of structure after fire.

In this publication the system of changes in nature and in climate of the Caucasus from the northwest to south-east direction are researched as a basis for the analysis of the condition of the animals and plants.

There is factual system of a structure of altitudinal belts in the Caucuses. The sorts of the animals and the area of their inhabitation is under the influence of this system.

In the work activity of some digestive enzymes participating in hydrolysis нутриентов of the albuminous and carbohydrate nature at молоди Black Sea кумжи Salmo trutta labrax Pallas and стальноголового of salmon Salmo gairdneri Rich has been investigated.

The peculiarity of migrations birds of prey in Precaucasus region is considered. Are analyzed date, character and direction of spring and autumn migrations, distribution and number on 19 species of Falconiformes.

The peculiarities of cuticulaglifics (“patterns” out of cuticular plates) of the hind leg of the fleas of the Ceratophyllidae family representatives, which are the distinctive features of many species, subfamilies and families are presented in this article.

As a result of our investigation of the South Dagestan fauna 325 species of Lepidoptera (Noctuidae), are revealed, including 181 species that are mentioned for the first time in the region of investigation, 4 species – in the Dagestan and Caucasian fauna and 1 species in the fauna of the Russian Federation.

Are studied individual questions of biology, ecology O. ovis, its distributions in the conditions of sharp reduction of number of population of the owner. Intensity and extensiveness gadfly's inculcatijn are established, places of localisation of larvae of all age, daily and seasonal activity imago insects and their feature biological mutual relations with an organism of the owner on larval development stages is studied.

The importance of macrophytes overgrowing spawning grounds located in the Volga River delta for the natural reproduction of roach is considered taking into account the depressive state of its stock. The key factors affecting the natural reproduction of roach are emphasized. Measures aimed at the enhancement of reducing processes are presented. The dynamics of nutritive base development, feeding, fish productivity of spawning grounds that are overgrown with macrophytes to different extent is studied. The present level of significantly overgrown spawning grounds is determined where the biomass of macrophytes negatively affects the development of their producing capacity.

The article is the first to provide data on the ecological peculiarities of the habitation of the blackstriped pipefish in the Kuybyshev water reservoir; and also on its morphometrical characteristics, age and sex structure, terms of spawning, prolificacy, nutrition. Data on content of heavy metals, toxic elements and radioactive nuclides is also provided.

Some aspects of ecology of groups of microorganisms concerning to Nocardia and Rhodocacus have been studied. Universal distribution of these microorganisms has been revealed. The new nutrient medium has been tested at allocation and cultivation of studied microorganisms prepared on the basis of geothermal water of not phenolic class.

The article deals with the environmental peculiarities of the water area sectors created as a result of the Caspian Sea division according to any principle. The correspondence between natural and human (state, administrative and economic) boundaries is assessed.

It is displayed that the composition of heavy metals compounds in water and suspensions in the area of marine and riverine waters mixing undergo natural changes due to sedimentation and transformation. The system “Volga Delta – North Caspian” as a geochemical barrier hampers the transfer of toxic heavy metals forms from the sea to the river, although the content of toxic iron and manganese forms at the marine border of coastal waters can reach up to 30% of total concentration.

In work attempt of division into districts of the city environment of industrial centre on the basis of geosistem-ecological (geoecological) the approach is resulted. For territories of city of Astrakhan it is allocated 7 ecological-depressive areas.

Eco-tourism is actively developed in high lands up to nival-glacial zone. Recreational resources are the object of eco-tourism, and, first of all, in national parks (zones: intensive and extensive recreation, buffer and difficult-to-access one), but every park has a specific profile, its own “ecorecreational face” and eco-touristic component. They can be used as a characteristic of park classification, as well as a terrain morphostructure. In general, the effective development in mountains requires to take into account eco-touristical features.
