It is popular to lean upon the bioclimatic models while discussing global warming influence on land and water ecosystems. These models to some extend assume similarity of phenological reaction of organisms on air temperature rising. In this connection the results of nine-year phenological observations of 22 forest plant species (trees, bushes, herbaceous perennial and annual plants) of broadleaved-coniferous zone in European part of Russia are considered. It is shown that species with early and late flowering demonstrate differently react on temperature rising in spring period. The reasons of unequal reaction of organisms on global warming are briefly discussed. As a whole the results of research confirm the assumption that species with early flowering most sharply react to climate warming.

In the Ulyanovsk region the estimation with help Acer platonoides L. is carried out bioindication. It is established, that A. platonoides L., growing on adverse under ecological characteristics to territories, are characterized by increase drought resistancea sheet that is expressed in reduction of the area of a sheet plate and increase of factor of the form of the central blade of sheet A. platanoides L.

In article major factors of risk of development diseases for building university students' and building complex workers' in the conditions of a capital megacity are considered. It is revealed that as such factors as improper feeding, high level of stressful pressure, hypodynamia, distributions of smoking and beer alcoholism are in sample of students. The important place in structure of risk development diseases to sample of building complex workers' in the conditions of a capital megacity occupies a wrong way of life. In disease structure illnesses of respiratory organs, musculoskeletal and nervous system prevail.

With the help plural of the analysis (correlation, factors, regression) the influence of socio-economic factors on sickness rate of the population of the Jewish autonomous region (JAR) by various classes of illnesses is investigated. The socio economic parameters, having the greatest reliability influencing on sickness rate of the population are revealed most information, priority. The mathematical models determining quantitative communications between priority socio economic parameters and such classes of illnesses, as illnesses of blood, blood making organs, endocrine of system, frustration of a feed and infringement of an exchange of substances, bodies of digestion, bone-muscles of system and connecting fabric, urine-genital of system, mental frustration and frustration of behavior are received.

The article discusses the opportunities of improving the quality of the learning process of school students through developing their adaptability to stress factors, which results in a better physical condition, improved academic and physical performance of students.

Results of a 2-year greenhouse experiment have shown, that fertilizers differently effect on spring wheat productivity and heavy metals accumulation in the plant. Contaminated with Cd, Zn и Сu soddy-podzolic soil shown 10-45% lower wheat yield, compared with the soil without heavy metals. Zn effects more negative on growth and formation of wheat yield, especially in a variant with NPK-amended soil. In the second year, the effect is the same. Suprodit-amended Cd, Cu and Zn contaminated soil showed a 1,4-2,0 lower uptake of heavy metals in the plant than NPK and nitrophosphate-amended soils in the first year and a 1,4-2,2 - in the second year.
