Changes in the fluorescence parameters of the photosynthetic apparatus of lichens, induced by pollutants and drying, were studied. We suppose that fluorescence can be used for biomonitoring to assess the state of lichens.

Through a comprehensive physiological analysis of forest inventory data stands of Scots pine, Norway spruce, English oak and Downy birch Republic of Belarus, were obtained the quantitative data of net photosynthetic productivity, mineral and biological productivity and carbon sequestration in plants in ontogenesis at the organism level and the nature of the relationship between these parameters. The presented method of comprehensive analysis of forest inventory data can extend the range of research in ecology and physiology of trees.

The article deals with the study of the influence of environmental factors and social conditions of a major metropolis on the adaptive nature of the reactions of students in the first year of study. Shown that young people who come from all over Russia and CIS, compared with the Muscovites have a higher percentage of unfavorable adaptation reactions.

Article is devoted to studying of various strategy of coping behavior of teachers depending on motivation level to innovative activity on the example of teachers of the higher school of the Republic of Byelorussia. On selection of 127 people during psycho diagnostics two groups are revealed: teachers with the high and low, average level of motivation to training to new innovative technologies of professional activity. Further testing (a questionnaire "The indicator of coping-strategy" CSI) showed various coping-strategy. So at teachers with high level of motivation to training to new innovative technologies strategy “solution of problems” often prevailed, and teachers with the low and average level of motivation to training to new innovative technologies strategy “avoiding” and strategy “search of social support” respectively often dominated.

The results of biological testing of soil samples, and Vietnamese rice infusoria Tetrahymena pyriformis using an automated device BioLaT and compare the results with the results of bioassay on daphnia and fitotesta, as well as the results of analyzes. A new method for extraction of fat-soluble compounds from the soil through the combined extractant consisting of acetone and bile solution in ethanol.

As far as fracturing assessment is concerned the information completeness of the data is responsible both for the geoecological forecasts reliability and the engineering decisions implementation. Authors developed a new technique allowing to provide a computer assisted process of drawing charts for the assessment of rock fracturing and an filtration anisotropy. The detailed description and justification of this technique as well as examples of its application are provided.
