The aim of this work was to identify the degree of tepal bend shape variation in representatives of six Colchicum s.l species: C. laetum L., C. ancyrense B. L. Burtt, C. bulbocodium var. versicolor (Ker Gawl.) K. Perss, C. umbrosum Steven, C. trigynum (Steven ex Adam) Stearn, C. eichleri (Regel) K. Perss. In each of the 53 populations located in the territory of European Russia, 30 plants were studied. The analysis of tepal bend shape variation was carried out using the geometric morphometry method. Principal Component Analysis (PCA) showed that C. laetum and C.

The purpose of this study was an environmental assessment of the contamination of medicinal plant raw materials of the Rostov region with sim-triazine pesticides.

Bird habitat capacity depends of forest community vertical heterogeneity in a most degree. Recreation intensively and force have a great influence on forest habitats organization and as a consequence – changes in bird species diversity and total breeding birds abundance.

The paper summarizes the basic results of the research concerning the application of some concepts of chemical physics in environmental protection and life safety.

Short-term fluctuations of the bird number and distribution, exhibiting a reliable relation with microclimatic phenomena (weather features of adjacent seasons, the nested population value in the previous year etc.) are shown.

By means of annual sociological surveys of the population of the Saratov region the level of its environmental consciousness, the dynamics and dependence on various factors (including mass-media campaigns) were studied.
