The results of studying four mountain lakes in different climatic zones (in regions of the Kola North and the Western Caucasus) are given. Original methods of paleoecological reconstruction developed by the authors have been used to characterize the main trends and rates in environmental changes at historical scale (by geochemical composition and diatom complexes in bottom sediment layers). Similar processes of modern water enrichment by metals (especially, Cd and Pb) have been determined in the examined lakes. Trends in changes in acid-base balance in The Kola North lakes since the late XIX century have been identified, reflecting the effect of transboundary transport of acid-forming substances from industrial Europe. Studies of diatom complexes in Caucasian lakes showed a rise in the mean annual temperature of lake water during the XX century supposedly by 1.5°C. 相似文献

Data on diatom complexes from bottom deposits of Lake Karakel’ (the Karachayevo-Cherkessian Republic) have been analyzed. The principle of unification of bioindication methods has been applied. The hydrological parameters of lake water (temperature, pH, and saprobithy) have been reconstructed over a period of 2000 years. The results of isotopic dating of bottom sediments have been used. For the first time for the Central Caucasus, the current and Late Holocene diatom alga complexes have been described. Photographs of the most abundant and significant lower taxa of diatom algae are given. 相似文献
