Annotation

Plant adaptation problem to a changing environment is relevant to the regional and global biology. Climatic factor varies throughout the year, causing the seasonal rhythm of plant development. Alternation of wet and dry periods in the seasonal rhythm of the plant causes feedback from plant systems at different levels (organism, population, phytocenosis). Description responses of plant species has a disjunctive area, on the climatic factor is represented in the work. For the first time in the region were obtained results related to the behavior of population systems plants surviving the stress due to climate anomalies (high temperatures and drought). Similar studies have not been conducted before. The climate was more stable, and methods of population analysis did not have wide application. The study was conducted by using the methods of population ecology of plants. This is a description of the seasonal rhythms of individuals of a species under the canopy of broad-leaved forest in different years and comparative population analysis. The latter includes: 1) descriptive statistics morphometric parameters of selected elements of the population of the species in different phytocenoses; 2) an analysis of the distribution curves of the same; 2) analysis of the correlation matrix. Characterize by different population systems; 3) a comparative analysis of similar data obtained at different times at different points of the species range. The research was Asarum europaeum L. (Aristolochiaceae) cenopopulations in the forest. The results showed that in response to climatic factor occurs substantial restructuring within the population of the species. It is reflected as follows: during the complete loss of assimilating organs evergreen herb A. europaeum comes in the middle of the growing season in response to prolonged dry with high air temperature period (climatic anomaly). Resumption of assimilation activity of individuals and restoring projective cover species takes place gradually over several years. The rate of this renewal is largely due phytocenosis factor. Ramet that survived the crisis and restore the activity of assimilation in the second year after anomalies were a number of indicators: 1) a straight plagiotropic shoot length over 26,7-44,9cm; 2) 1-2 pieces assimilative leaves; 3) 13,1-47,3 cm2 assimilative surface area; 4) the length of 3,1-7,2cm leaf petioles. Ramet have a low level of variation indicators. The distribution pattern of ramet all indicators is not left-modal
