The results of comparison show that in clear cutting populations of a bank vole fluctuating asymmetry is higher and correlations of signs development is lower than virgin forest populations. It indicates that stability and regulation of ontogenesis decreases in the ecological disturbed ecosystems of clear cuttings.

Results and periods of hollow nesting are influenced by a lot of factors, the main of which are weather dynamic conditions. An influence of periodically changeable climatic factors which effected by circulating processes in the atmosphere upon behaviour and development of Starling is searched in the work.

The model of silting of the settling pool is offered here. The methods of definition of parameters of the model by experimental figures are reduced. The factors, determined the maximal productivity, and necessary conditions of their optimization are considered.

Biologically active dietary supplement «Transfer-factor» obtained from cow colostrums by the company «4 Life Research Co» (the USA) has positive impact on the immune characteristics of the old laboratory animals and displays the complex gero-prophylaxis influence on the mice's physical state, dynamometric figures of the animals, the metabolism and the free radical mechanisms of ageing. «Transfer-factor» renews the cellular potential growth of old animals' tissues to the values specific for the young age. It can be used for the tissue regeneration activation with the purpose of their healing. As important is the described in the work anti-stress action of this remedy on the immune system and its protection impact on the age-specific and alimentary obesity.

The aim of the research is the study of the regularity of the phenotypic manifestation of the level of chromosome aberrations and of the transcriptional activity of chromosomes' kernel-forming areas on the example of arterial hypertension development. The obtained results proved the influence of the activity of the kernel-forming chromosomes' areas and the formation of chromosome aberrations on the development of the arterial hypertension in people.It was demonstrated for the first time that people with high transcriptional activity of chromosomes' kernel-forming areas have the lowest level of chromosome aberrations, which is explained by a high proliferative activity of this group and by a more intensive protein synthesis (including reparation proteins). The data on adaptive significance of chromatid chromosome destructions holding back the development of the arterial hypertension have been obtained. Thus, the interrelation between functional Ag-polymorphism and the level of chromosome aberrations during the development of arterial hypertension in people has been established, linear dependence being absent between these two characteristics.

Population health is a sensitive index of the ecological state and serves as the main biological indicator in the sphere of medical-ecological monitoring.

In article the results of the research work of series of springs are stated. Regularity of change of spring water quality under the influence of man-caused factors is revealed. Such factors as geological structure of rocks, sorption characteristics, presence of trees plantations etc., are very important for prevention of spring water pollution.

The large-scale environment pollution and its fatal influence on forest ecosystems has led to deterioration of a sanitary condition of forests in Belarus, to reduction of their biological resistance, to mass reproduction of many destructive insects and fungous diseases. The common pine - one of the basic forest creators in Belarus - is widely used as object for test due its high sensitivity to contamination. A number of works offer to use alterations in content of separate ingredients of an essential oil of a common pine as biochemical indicators of terrain industrial pollution. It is necessary to note also, that the basic biochemical processes in needles cells fade during the autumn-winter period, and radioactive disintegration does not stop, that causes the accumulation of radioactive products and, finally, leads to increase of stressful loading on the tree biomass. It was note, that the biochemical indicator - essential oil componential composition - is rather sensitive to quantitive changes of toxic elements and radioactive nuclides in conifer needle. The mechanism of influence of various elements on biosynthesis terpenoids is complicated enough, however some similarities in influence of toxic elements and radioactive nuclides on the process is marked.

In the article the estimation of volumes PTF-bottles acting on ranges of firm household waste products in the Russian Federation is given. The most widespread methods of secondary processing of PTF-bottles in the world and in Russia are analysed. The analysis of large pilot programs on separate gathering and secondary processing of the firm household waste products which are carried out in territory of the Russian Federation is carried out.
