The main idea of this work is define a problem of human ecology, the aim of which to understand outward forms and inward mechanisms of adaptation of social and biological sphere at the different stage of human development. The modern human lost the contacts the nature in a considerable extent. The extent of ecologically personality’s development bounds up with high morals and recreation activities. It forms different needs such as world outlook’s integrity, syncretic of consciousness, freedom of thought and creation, aspiration for realization, for harmony and others in this conditions ecological crisis. Vital activity must be bases upon responsibility’s principle for the future conditions of our planet. The particular importance assumes the process of forming by ecological world outlook at this time, so as the main role at the process of human’s adaptation is
consciousness.

There are resulted the ecological bases of a biodiversity saving of the sea-bottom organisms of the Northern Caspian.

In the territory of Dagestan we studied the ecologic faunistic characteristics of the Echinostomatidae. During researches in republic 10 kinds of Echinostomatidae are noted relating to three types: Echinostoma, Echinoparyphium, Hypoderaeum. The most widespread kinds of Echinostomatidae in the territory of Dagestan are Echinostoma revolutum and Echinostoma corvi.

The presence of mosquito in biotopes is caused by different physical-geographical conditions, by habitat of spreading of suckles of mosquito, and also conditions of reception of to abrovirus. The largest number of species of mosquito Culex is met at a flat best. The least number of species are met at a mountain best.

Formation of carabid’ fauna Ciscaucasia has begun, possibly, in the epoch of beginning Cretaceous. There were the serious changes of landscapes during the subsequent epoch. They have led to formation of modern fauna.

Peracarilae – Paramysis (Paramysis) intermedia, Paramysis (Paramysis) kessleri, Paramysis (Mesomysis) lacustris, Limnomysis benedeni, Niphargoides (Pontogammarus) robustoides, can live in mountain lakes of Dagestan.

Dagestan Republic is a zone of complex beekeeping. To ensure favorable ecological and economic conditions of bees’ live bees it is necessary to estimate first of all an ecological condition of bee families, using thus melliferous bees as bioindicators.

The general character of distribution amphipodae mainly depends from abilitus to reach a food peculiar to all amphipodae.

The stream trout is one of the kind preferring pure ecological conditions, according to this kind maybe an indicator of ecological condition of environment in the Chechen Republic. That’s why studying biology of this kind is actual, to find out its condition in present.

Sheep living in the area of technogenic pollution have heavy metals accumulation and changes in histological structure of organs and tissues in ontogenesis as well.

The level of toxicants was studied, and the biological value of sheep meat in the area of anthropogenic influence was checked up. The level of toxicants in meat depends straight on the age of animals.

Functioning of particularities of adaptively-compensatory mechanisms have been identified in sheep living in different ecological zones.

Monitoring the state of the glutathione system in blood of sheep in the area of technogenic pollution revealed the significant changes in the concentration of common glutathione and its fractions (reduced and oxidized).

The impact of ecological, trophic and anthropogenic factors on biological characteristics of zander is shown. Specific features of water regime in the Ural River that limit zander abundance are determined.

There were researched 314 animals related to 6 genious in different zones of Azerbaijan. It is defined that 6 genious helminthes parasits on Sсiurus anomalus, 2 genious helminthes parasits on Hystrix leucura, 5 on Myocastor coypus, 3 on Dryomys nitedula, 13 genious helminthes and etc. parasits on Arvikola terrestris –totally 28 helminthes. There were fully analyzed bioecological connection with different living organisms in Azerbaijan.

This article contemplates nest ecology of the house sparrow (Passer domesticus) and the tree sparrow (Passer montanus) living in the conditions of the central part of Ciscaucasia. In the publication we can see an observation of nest – building, clutch – sizing and the effectiveness of breeding of the birds of both species.

The article presents the data, that the toxical effect of nitrites and their accumulation in water ecosystems. Formation of methemoglobin as a result of nitrite intoxications, leads to destructions of the metabolism and morphophysiological processes. Reaction of fishes to nitrites depends on the species and age of fishes, a dose of the nitrite and chemical composition of water.

Helminths are wide spread among agricultural animals. They bring huge damage to stockbreeding decreasing of production, and in some case bring out ruin of animals. The preparation using against, helminth are disturbing bacterial flora of stomatic and intestinal track of animals.

Within the limits of the town the lakes is permanently exposed to negative man's impact. In such conditions their protection demands special arrangements.

Landslide process manifests itself by taking off and climbing down under the influence of force of gravity masses of friable rock, mostly formed by taken turns of waterproof and water-carried stratums, particularly in case of satiation of friable rock by water.

Long-term sanitary-microbiological monitoring indicated persistence and domination of opportunistic bacteria of the families Enterobacteriaceae, Pseudomonadaceae and Vibriona-ceae in water and among hydrobionts which is indicative of unsatisfactory sanitary characteristics of the species under study. Most of the isolated microflora showed various degrees of pathogenicity and multiple resistances to antibiotics. This is suggestive of epidemiological importance of isolated microorganisms.

On the ground of data obtained in 1998 – 2007, it was demonstrated that the geochemical barrier of the Volga delta – the shallow water of the North Caspian - serves as a filter preventing natural and anthropogenic hydrocarbons from entering into the high sea with the river runoff. This circumstance explains a relevantly low level of the north Caspian offshore pollution and increased toxicity of desalinated water of the North Caspian in comparison to marine water.

There are defined the bottom sediments of the Caspian sea. Heir role in harlot metals accumulation and their impact on physiological state of the sturgeon fish.

The processes of degradation and evolution of soils because of natural and anthropogenic factors` influence were considered in East Pricaspy.

High adaptive ability of honey bee allow them notoney to settle versions ecological niches but to in flucuce favorably on their stability and productivity as a result of mutual coadaption honey bee and flowering plants.

The present condition of soil cover and biological productivity of Tersko-Sulakskaya lowland’s forage plants is studied. The conducted investigations showed that overwrite forage plants on the salted soils have low forage productivity and nutritive value. The soils under it need a deep melioration measures.

Landscape spatial structure of the Russian part of the Caucasus analyzed. Evaluation of adequacy of existing federal network of protected areas (nature reserves and national parks) done based on that analysis. Expansion of the network is suggested by including of new nature reserves in semi-arid, forest-steppe and sub-Mediterranean scrubland landscapes.

With the help of this article there has been made an attempt to show the role and the significance of regions values in stating harmonic relationship between a human being and nature, aiming at environmental protection.

Wetlands are areas of special protection status due to their extraordinary significance for the preservation of some animal species and their natural habitats. Despite the fact that such territories preserve valuable animal and plant species, they remain unknown for the community and their resource potential is not used optimally. Based on the concept for sustainable tourism development, this paper offers a model for their recreational assimilation in comply with tourism purposes, especially through tourism development. Under analysis are the Ramsar sites in the countries of the Balkan peninsula. Some recommendations and conclusions are made on the basis of their assessment and unused resources.
