302 The recent reduction of emissions from industrial enterprises to the atmosphere occurring in many countries motivates studies of natural ecosystem recovery. They are important both theoretically, with regard to resilience mechanisms, and practically, with regard to proper management of natural resources. However, the investigation of processes involved(More)
The effect of long-term exposure to a stress factor on the pattern of variation and intrapopulation differentiation with respect to phenotypic plasticity was studied in Crepis tectorum L. by means of family analysis of various traits in seedlings. Trends in the changes of variation patterns in populations and the possible consequences of the decrease in the(More)
The state of tree and ground vegetation layers in spruce-fir forests around the Middle Ural Copper Smelter (Revda, Sverdlovsk oblast) has been repeatedly evaluated in 25 permanent sampling plots at 5- to 10-year intervals (1989–2013). The results have been used to characterize the dynamics of plant communities in the period of reduction of emissions from(More)
17 The decrease in biota diversity caused by human activity is able to affect ecosystem functions on both local and global scales [1]. The main reasons for a present day increase in the species extinction rate are the loss, fragmentation, and decreased quality of hab itats [2]. Pollution is one of the factors resulting in the appearance of areas that are(More)
Recovery of the species richness of plant communities after experimental disturbances of various severities were studied in spruce forests polluted by atmospheric entry of SO2 and heavy metals from a copper smelter. In the three toxic load zones (impact, buffer, and background), 60 experimental “pit-and-mound” complexes (sized 1 m × 2 m, 20 complexes in(More)
Aftereffects of exposure to long-term chemical pollution with fluorine and sulfur compounds on intrapopulation differentiation of the rates of growth and development has been studied on Crepis tectorum L. progenies obtained from seeds collected in a pollution gradient and grown in a greenhouse under uniform ecological conditions. The results have shown that(More)
Specific features in the distribution of plant species differing in their attitude toward thermal conditions have been studied in communities of the present-day timberline ecotone on Mount Iremel’ in the Southern Urals. It has been shown that the distribution of such species is characterized by significant spatial nonuniformity. Elevation above sea level,(More)
The effect of temperature and soil contamination by fluorides on the early stages of the growth and development of narrowleaf hawksbeard plants from polluted and nonpolluted habitats has been studied. The character and degree of manifestation of the combined effects of pollution and temperature, as well as the variations in the direction of response(More)
Climate warming is shifting the elevational boundary between forests and tundra upwards, but the related belowground responses are poorly understood. In the pristine South and Polar Urals with shifts of the treeline ecotone documented by historical photographs, we investigated fine root dynamics and production of extramatrical mycorrhizal mycelia (EMM)(More)
The results of demographic studies on Crepis tectorum L. populations from polluted and clean habitats are presented. They show that these populations significantly differ from each other in a number of parameters, including the seasonal dynamics of seed germination, the number of generations, the time of plant transition to reproduction, and the rate of(More)
