This work shows the changes in the composition and structure of zoobenthos communities in the mountain rivers of the Belaya river basin (the North-West Caucasus), influenced by high water. Discuss how various factors of the environment in the conditions of stream affect zoobenthos communities during high water events. The new concept "hidrotranselimination" is proposed, which reflects a complex influence of high water on zoobenthos communities of stream.

In the forest and fruit conenoses Absheron, identified 37 species xylophagous harmful to forest crops. Of these, 6 species (Lucanus ibericus L., Oructes nasicornis L., Perotis lugubris Sub., Dicerca aenea Sem., Megopis scabricornis Scop., Cerambyx cerdo L.) are the most serious pests. Their bioecological particular economic importance and natural enemies has been studied. We have found that 34 entomophagous play a role in regulation of the number xylophagous. Of these, 12 species have economic value, of which 4 types (Xorides irrigator F., Atanycollus initiator Nees, Nidobius umbratus Mots., Tanasimus formicarius L.) examined in more detail bioecology, distribution and economic value

Presents an analysis of long-term data on cancer incidence of the population of theChechenRepublic. Examines the state of water quality in districts and cities of the Republic to reveal in these areas carcinogenic and carcinogenic factors of the environment.

The survey of tuberculosis spreading in the world, Russia and Dagestan Republic, connected with peoples infection from sick animals, in given. Special attention is paid to the ways of infections transmission from animals to man

The problems of accumulation of copper, cadmium, lead and zinc in such objects of the environment, soil, pine and spruce needles, leaves, poplar, birch, elm and elm foliose squat on different parts of the city of Ust-Kamenogorsk, Kazakhstan. Shown that the maximum accumulation of TM characterized soil, pine needles (leaves) of the northern, central (residential) areas of the city.

It is found out 9 florotsenotypes which include 15 florotsenoelementen. The results of this comparison of tacsonomical structure of florotsenoelementen by means of factor of the similarity of Syorensena-Chekanovsky (Кsc) are given.

Ecological conditions of habitats essentially influence on phenological phases terms at Leucojum aestivum, Galanthus woronowii and Pancratium maritimum on the Black Sea coast ofRussia. The general duration of vegetation of Leucojum aestivum and Galanthus woronowii populations on the shaded habitats exceeds that for the opened habitats on 3 and 2 weeks respectively; Pancratium maritimum, on the contrary, differs continuous vegetation on open habitats. Despite earlier beginning of flowering in the shaded conditions, fruits maturing of Leucojum aestivum and Galanthus woronowii is noted for a week later, than on the shined habitats; flowering of Pancratium maritimum in the shaded conditions can not be observed.

It is shown that the known vegetation index edge of the red zone (REP) can be presented in the form of the sum of two components from increased content of nitrogen in the air and the vegetation under normal conditions of air pollution.

The method of study of correlation of the index REP and protein content in plants, where the impact of air pollution with nitrogen gas is excluded. 

Dynamics of dying leaves investigated the eighteen species of herbaceous plants geranium-kopeechnikovy meadows in the Teberdinsky reserve.

The duration of the withering away of the individual leaves of summer-green plants geranium-kopeechnikovy meadows is on average from 9.6 to 11.8 days. Leaves of summer generation in the summer-winter-green plants die off from 10.2 days (Luzula multiflora) to 14.3 days (Carex atrata), while the leaves, leaving the winter green die within a few months. The Rhododendron caucasicum
part of the leaves died out in the average for the 14.9 days, and the leaves, dying for several seasons - within 10 months.

In article selitebny load of mountain and flat landscapes of the North Caucasus is considered. As a result of application of cartographical methods the spaces occupied by the main landscapes, are compared with the areas of settlements in their limits. The number of settlements within landscape contours, and also their average area is defined. It is revealed that foothill landscapes to Ciscaucasia and mountain kotlovinny landscapes – in the territory of Greater Caucasus are subject to most selitebny loading.

The features of the accumulation of copper, zinc, lead and cadmium in the soil of Ust-Kamenogorsk. Soils of different areas of the city are characterized by different levels of pollution. The maps of the diagram of distribution of chemical elements and their associations in the soils of the city.

The ecological status of the river Argun and Squirrel. It is shown that the Argun River and Squirrel are classified as "moderately polluted" water quality class III. The basic measures to protect water resources from pollutants CR.

In this article we studied the features of ekological and geochemical pollution by heavy metals урбаноземов Kaspiysk are investigated. The card of total pollution of soils of an urban area is made.

The content of persistent organic pollutants in agricultural and residential areas of the Czech Republic. Elevated levels of PCBs in samples of agricultural use found near the city of Grozny and Argun. Dioxin is the most polluted soil in areas of the asphalt plants.Mesker-Yurt.
