Spatiotemporal Biomass Changes of Tree Stands at the Upper Limit of Their Distribution in the Altai-Sayan Mountains in the Past and near Future

Pavel Moiseev, Nail’ F. Nizametdinov, Anton M. Gromov, Dmitry S. Balakin et autres

Global warming, which is mainly linked to CO2 increase, has led to a growing interest in assessing carbon conservation in forest biomass. Despite evidence that treelines have advanced by hundreds of meters, knowledge of associated stand biomass changes is insufficient for comprehensive …

Response of woody vegetation and soils to modern climate change in the Altai Mountains

Andrey A. Grigoriev, Irina N. Korkina, Sergey O. Vyukhin, Yulia V. Shalaumova et autres

The upper forest boundary in the mountains is a reliable bioindicator of modern climate change, though its dynamics are influenced by multiple factors. Conjugate studies on the structure of tree stands and the soil properties across the elevation gradient were performed at …

Mapping Long-Term Changes in Forest Cover Using Multispectral Satellite Remote Sensing Data

Mikhail I. Bogachev, Andrey A. Grigoriev, Yulia V. Shalaumova, Nataliia A. Obukhova et autres

Introduction. Shifts in the habitat ranges of tree species are among the continental-scale consequences of climate change. Mapping these shifts and their quantitative estimation are essential for evaluating the carbon balance. In this work, a method for mapping long-term changes in forest …

Structural Changes of Stands on Their Upper Limit at the Polar Urals over the Last 60 Years and Factors Effecting on Tree Establishment Rate

Pavel Moiseev, Valeriy S. Mazepa, Dmitriy S. Balakin, Yulia V. Shalaumova et autres

Abstract Climate has altered rapidly since the end of XIX century and species’ ranges advanced worldwide to higher latitudes and altitudes in response to changes of the environmental conditions. The most facts of treeline advance in response to global warming in the …

Alpine Shrubification: Juniper Encroachment into Tundra in the Ural Mountains

Andrey A. Grigoriev, Yulia V. Shalaumova, Dmitriy S. Balakin, Olga V. Erokhina et autres

Snow cover is one of the most important factors affecting the regeneration and growth of shrubs in cold arctic and alpine ecosystems. In many of these cold regions, climate change in the last century is manifested not only in a rapid rise …

Stand Biomass at Treeline Ecotone in Russian Subarctic Mountains Is Primarily Related to Species Composition but Its Dynamics Driven by Improvement of Climatic Conditions

Pavel Moiseev, Frank Hagedorn, Dmitry S. Balakin, Maxim O. Bubnov et autres

Climate change effects are strongest in forest ecosystems at the limit of their distributions. Despite the evidence that treelines have shifted upwards by hundreds of meters, knowledge of the associated changes in the stand biomass is limited. In this study, stand biomass …

Upward Treeline Shifts in Two Regions of Subarctic Russia Are Governed by Summer Thermal and Winter Snow Conditions

Andrey A. Grigoriev, Yulia V. Shalaumova, Sergey O. Vyukhin, Dmitriy S. Balakin et autres

Climate warming impacts on alpine treeline dynamics. However, we still lack robust assessments of the long-term impacts of climate on tree recruitment at the treeline, particularly in remote areas such as the subarctic regions of Russia subjected to different climate influences. We …

Current Expansion of Juniperus sibirica Burgsd. to the Mountain Tundras of the Northern Urals

Andrey A. Grigoriev, Yulia V. Shalaumova, Dmitriy S. Balakin

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 …
