Abstract—Northern and tundra forest ecosystems are especially vulnerable to climate impact because of their high sensitivity to changes in temperature. An important issue is how the growth and productivity of the main forest-forming species in the permafrost zone of Siberia are changing under conditions of current climate change. In this study, the...

Abstract—In recent years, the supra-long Yamal tree-ring chronology has been significantly extended and became much more reliable. This article characterizes the sample wood used to build the longest absolutely dated Siberian Larch tree-ring chronology of the Subarctic area, i.e. from 6748 BC to 2019 AD, for a total continuous period of 8768 years....

Abstract—Ecosystems of high-mountain and high-latitude regions are especially sensitive to changes in climate conditions. A considerable part of recent publications on climatogenic transformation of plant communities deal with the dynamics of the upper treeline, while similar studies on shrub vegetation are scarce. Our study on the age structure of...

AbstractOne of the fundamental problems of modern ecology is assessment of the response of woody plants to environmental effects under changing climate conditions on Earth. Various simulation models of tree ring growth can serve as an effective tool for solving this problem. We have proposed a new simulation model for the functioning of cambium, wh...

Abstract—Climate change entails shifts in the ranges of woody plants along both latitudinal and altitudinal gradients in the boreal forest biome. In this study, dendrochronological and GIS technologies have been used to evaluate shifts in the upper distribution limits of trees and shrubs in the Eastern Sayan Mountains. The results show that upward ...

AbstractRecent climatic changes significantly affected forest ecosystems in northern Eurasia. Trees growing in Siberia are very sensitive to climate change due to strong temperature limitation of their growth. Our study covers high-latitude (northeastern Yakutia, eastern Taimyr, central Evenkia) and high-altitude (Russian Altai) zones in Eurasia, w...

AbstractIn the southern tip of the Urals, late spring frosts, which regularly damage the leaves of the common oak (Quercus robur L.), are reflected in the formation of a specific anatomical structure of annual rings. The identification of calendar years with damage to oak leaves by late spring frosts, carried out on the basis of the known and revea...

AbstractThe question of the nature (random or ordered) of the loss of species in plant communities as a result of an increase in the participation of dominants is considered. The objects of study were 15 sites of communities of different types: riverbanks, forest meadows, steppes, subalpine and alpine meadows of the Western Caucasus, macrophytobent...

AbstractThe dynamics of the species richness, breeding density, and structure of the community of birds occupying nest-boxes upon a 50-fold reduction of atmospheric emissions from the Middle Ural Copper Smelter was analyzed based on long-term continuous observations (1989–2020). The total density in the deciduous forest was lower in the heavily pol...
