The materials about the phytoplankton composition and distribution in the Daghestan region of the Caspian Sea in connection with changing hydrologicaly-hydrochemical regime in conditions of anthropological and biological environment are presented. It was shown, that the change of water regime brought to alterations in floristic composition of sea weeds and succession of phytoplankton change group. Water biocoenosises of different seacoast zone distinguished specific character
dynamics. Introduction of Mnemiopsis leidyi (A. Agassiz) influences on phytoplankton association structure

Influence of a mineral nourishment on the growth, optical parameters and activity of the photosynthetic device of the plants which have sprouted on water, sandy and soil environments was investigated. The received results of researches expand representations about possibility of the decelerated to fluorescence use for express diagnostics of environment condition.

In article the general botaniko-geographical structure of flora of east part of the Skalistyj ridge and a vysotno-zone picture of distribution of the kinds concerning different geographical types and elements is analyzed.

In article data on new sites of tertiary relicts are resulted and the state of their populations is characterised.

Comparative analysis of three ecological factors influence on changeability of generative sprout dry mass features in general and its components (leaves, stalks and floscule) hast been accomplished at the beginning phase of flowering of four species of clover: Trifolium ambiguum, T. medium, T. pratense and T. raddeanum of mountainous Daghestan. Structure influence of these factors on generative sprout weight features has been found. Maximum of the floscule dry mass is observed in Daghestan high mountain endemic T. raddeanum. Increase of the dry mass of the floscule in the sprout mass in general and of the main factor of the adaptive strategy Re with the height gradient growth are observed both at population and species levels.

Intestines of IVth stage larvae of mass species of bloodsucking mosquitoes from the zone affected water reservoir have been studied. As a result it has been established that the main components of their food are algae, detritus, mineral particles and remains of zooplankton.

The Presented results of the studies to biologies Pontogammarus maeoticus. Special attention is given reconstruction typical of coast water biocenoses amphipod, which was destroyed as a result of lifting sea level. Most important environmental factors, that influence cenoses are noted.

The analysis of a qualitative condition of a soil integument is given in the paper.Environmental problems of soils protection and their rational use are considered.

Benthic biocenoses of the Dagestan area of the Caspian Sea were studied. Considered distribution, composition and structure benthic in connection with observed change in environmental conditions. Special attention is given influence Mnemiopsis leidyi (A. Agassiz) on condition zoobenthic.

The aim of this study was to estimate the links between chemical composition of drinking water and a level of arterial pressure (AP) and prevalence of an arterial hypertension AH) in populations in highmountainous (Kulinsky,Tljaratinsky, Tsuntinsky areas) and plane regions (Nogajsky area ) of republic Dagestan. Drinking water in high-mountainous region was low mineralized (128, 24±7, 41 mg /l). A parity of anions was HCO3SO4 CL, the parity of cations was Сa>Mg>Na. In plane region drinking water was more mineralized (633, 26±22, 56 mg /l) the parity of anions was HCO3 > SO4 > Cl and the parity of cations was Na> Ca> K> Mg. It was revealed, that in a high-mountainous region agerelated levels of AP were lower, than that in plane region. Age increase of BP was negligible. Prevalence AH (BP≥140/90 mm Hg) in high-mountainous areas was accordingly equal 5,67±0,48 %., 4,21±0,93 %, 7,23±0,73 %. In Nogajsky area the prevalence of AH was equal 26,90±0,92 %.
