150-th Anniversary Dokuchaev’s Pupils — Vernadsky V. I. and Williams V. R. From the Mind to the Sphere of Reason Trofimov I. A., Trofimova L. S., Yakovleva E. P. Eminent Russian scientists v. V. Dokuchaev, v. I. Vernadsky and v. R. Williams dedicated his life to solving important problems of a systemic approach to the study and reasonable, respect for the Earth. Their names associated major breakthrough in biology, geography, ecology, environmental management, agricultural research and development in practice of their results. Shows the crisis of agricultural lands of the planet, Russia, Central Chernozem region and the ways of environmental management in agriculture.

Petrol Products in Soil. Terminology and Definition of the Problem Okolelova A. A., Bezuglova O. S., Kasterina N. G. The term «oil products» can be defined both in technical and analytical ways. From a technical point of view, oil products (OP) are raw oils after the initial processing at the excavation facilities. Methods and definitions of water diagnostic limit the term «oil products» to soluble hydrocarbons. We propose to replace the term «organic carbon of oil toxicants» with «organic carbon of antropogenic origin». We furthermore suggest considering oil compounds as «organic pollutants» or xenobiotics. In the research it is suggested to calculate the oil content of the soils by the quantity of anthropogenic carbon. Additionally, the oil products accumulation factor (Kn) is suggested to use for an impartial assessment of the oil content in soils including the quality of their compounds.

The Influence of the Spatial Variability on the Goal-Directed Behavior Organization Serkova V. V., Nikolskaya K. A. The influence of the spatial variability on the goal-directed behavior organization in adult mice line F1 from DBA/2J and C57BL/6J was studied. It has been found that sudden change of initial structure of the maze during the moment of imprinting of spatial information has negatively affected on possibility to form the adaptive behavior in accordance with the offered task conditions. It is assumed that the constancy of the initial spatial information can be an system factor which together with the other will ensure the success of the cognitive process.

Spatio-Temporal Variability of Phytoplankton State of the Seversky Donets River Reshetnyak O. S. It was considered the variability of quantitative and qualitative indicators of phytoplankton communities in different parts of Seversky Donets. It is shown that the characteristic feature of the development of phytoplankton in period 2002–2011 is high variability of quantitative indicators, suggesting an unstable state community. In the composition of phytoplankton was recorded from 12 to 39 species, the dominant complex were compiled diatoms and green algae. Aquatic ecosystems are able to anthropogenic ecological stress by level of phytoplankton development.
