Differentiation of Soil Processes by Stages of Soil Formation in the Regions of a Dry Climatic Belt
Arid Ecosystems - Tập 12 - Trang 382-388 - 2022
M. M. Alichaev, M. G. Sultanova, P. D. Musalaeva
Modern manifestation of desertification stages and of arid degradation and the dynamics of the development of these processes depending on soil fertility under arid conditions are analyzed based on the example of some areas of the Western Caspian Sea Region: the Terek-Kuma Lowland and the Terek River delta. There are two stages of the development of degradation processes, which strongly differ in ...... hiện toàn bộ
Leymus Chinensis (Leymus chinensis (Trin.) Tzvelev) in the Western Trans-Baikal Region: Cenosis Structures, Production, and Biochemical Composition in the Current Growth Environment
Arid Ecosystems - Tập 11 - Trang 73-82 - 2021
M. G. Merkusheva, N. K. Badmaeva, L. N. Boloneva, I. N. Lavrentieva
The phytocoenotic characteristics of leymus-chinensis cenoses growing in soils of different types in the meadow–steppe, the floodplain–steppe, and the halophytic grasslands in the western Trans-Baikal region are considered. The botanical composition is found to consist of 28 glicophyte species, 17 halotolerant glicophytes, and 6 halophytes. It is determined that the genus Leymus contains three spe...... hiện toàn bộ
Mechanisms of primary successions on the Caspian Sea coast
Arid Ecosystems - Tập 1 - Trang 149-158 - 2011
L. A. Dimeyeva
Development patterns for vegetation on the Novo-Caspian plain are established on the basis of the study of spatiotemporal series. Three types of primary successions have been recognized, i.e., psammosere, halosere, and meadow sere, which differ in environmental conditions, regular features of temporal dynamics, and formation stages. The stages of the succession were identified on the basis of envi...... hiện toàn bộ
Features of Functioning of Constructed Wetlands in Arid Regions
Arid Ecosystems - Tập 11 - Trang 304-310 - 2021
K. Yu. Rybka, N. M. Shchegol’kova
This article discusses features of wastewater treatment in arid regions with constructed wetlands (CWs)—shallow artificial streams planted with higher aquatic vegetation. It is known that the efficiency of arid CWs at elevated temperature is higher with respect to some parameters than that of similar treatment systems in other climatic zones. However, arid CWs have a number of features that have n...... hiện toàn bộ
Trends of Variation in the Thermal Regime in Arid and Adjacent Areas in the European Part of Russia in Summer
Arid Ecosystems - Tập 11 - Trang 319-326 - 2021
L. M. Akimov
This paper presents the results of an analysis of trends in variation in the mean monthly air temperature in arid lands in the European part of Russia and adjacent areas in summer; the direction of these trends and the rate of temperature changes in the second half of the 20th and early 21st centuries are estimated. The regional features of the thermal regime in the European part of Russia (EPR) h...... hiện toàn bộ
Land Degradation of the Republic of Kalmykia: Problems and Reclamation Methods
Arid Ecosystems - Tập 10 - Trang 140-147 - 2020
E. B. Dedova, B. A. Goldvarg, N. L. Tsagan-Mandzhiev
The Republic of Kalmykia is located in the European part of the arid belt of the Russian Federation, in which the desertification of a significant part (up to 80%) of its territory is a serious environmental and socioeconomic problem. Thus, of the 6 264 000 ha of agricultural land, 77.9% are subject to various types of degradation, of which 93 960 ha are waterlogged, 526 180 ha are eroded, 1 753 9...... hiện toàn bộ
Increasing the Efficiency of Plant-Cover Restoration in the Modern Focus of Deflation on Pastures of the Northwestern Caspian Region
Arid Ecosystems - Tập 10 - Trang 358-367 - 2020
A. S. Manaenkov, L. P. Rybashlykova
The change in the use of forage lands in the Black Lands and the Kizlyar pastures of the Caspian Sea region in the second half of the 20th century from winter to year-round, their overload with livestock, and plowing for forage crops led to the degradation of natural ecosystems, an outbreak of light-soil deflation, and the formation of large foci (with an area of ​​hundreds or thousands of hectare...... hiện toàn bộ
Planktonic and Benthic Algocoenoses in Highly Mineralized Rivers that Drain into Lake Elton
Arid Ecosystems - Tập 12 - Trang 516-524 - 2022
O. G. Gorokhova, T. D. Zinchenko
This paper presents results of long-term (2008 and 2012–2019) studies of phytoplankton and phytobenthos in seven highly mineralized rivers of the Lake Elton basin. Two-hundred-and-fourteen algal taxa belonging to seven systematic divisions have been identified in the algal flora; of them, the division Bacillariophyta features the greatest species richness and abundance. A comparative analysis of t...... hiện toàn bộ
