  • On the 30th Anniversary of the “General Plan to Combat Desertification
           of Black Lands and Kizlyar Pastures”
    • Authors: K. N. Kulik; V. I. Petrov; A. S. Rulev; O. Yu. Kosheleva; S. S. Shinkarenko
      Pages: 1 - 6
      Abstract: This paper reviews the main historical stages of the development and implementation of the largest environmental project of the late 20th century—the “General Plan to Combat Desertification of Black Lands and Kizlyar Pastures.” The goal of this project was to implement a scientifically grounded set of measures to stop desertification processes, improve the economic state of pastures, increase their fertility, and protect lands. The implementation of the general plan has led to the performance of agroforestry works in an area of more than 7000 km2, the fixing of more than 4000 km2 of mobile sands, and the restoration of more than 2500 km2 of pastures. According to the forecasts, if all of the measures stipulated by the general plan were observed, the area of the ecological disaster zone would decrease and then completely disappear. A study conducted with Landsat satellite images showed that this forecast has partially come true: the area of open sands that was recorded in the test plot in 2016 (27.3 km2) is only 1% of the open sands area recorded in 1975, which is a consequence of the implementation of the general plan, a number of environmental measures, and favorable climate fluctuations.

  • Bioclimatic Subhumid Zone of Russian Plains: Droughts, Desertification,
           and Land Degradation
    • Authors: A. N. Zolotokrylin; E. A. Cherenkova; T. B. Titkova
      Pages: 7 - 12
      Abstract: The boundaries of bioclimatic zones (semi-arid, dry subhumid, and subhumid) on the plains of Russia were determined according to the values 0.35, 0.50, and 0.75 of the aridity index (AI is the ratio between mean annual rainfall and potential evapotranspiration). The potential evapotranspiration was calculated by the Penman formula. The dry subhumid area (dry steppe landscapes) is located between isolines 0.35 < AI < 0.50, while the subhumid area (mainly steppe landscapes on the East European Plain and forest-steppe ones on the West Siberian Plain) is located between 0.50 < AI < 0.75. The subhumid area is characterized by the high frequency of atmospheric and soil-atmospheric droughts in some regions which may be assessed as episodically arid regions. The satellite indicator of land degradation (albedo) shows a significant positive degradation trend in the dry subhumid and semi-arid areas and an unstable positive trend in the subhumid area.

  • Environmental Implications of Climate Warming for the Northern Caspian
           Region
    • Authors: M. K. Sapanov
      Pages: 13 - 21
      Abstract: The results of monitoring of the climatic and natural conditions of the semidesert in the Dzhanybek station of the Institute of Forest Science of the Russian Academy of Sciences (IFS RAS) in the northern Caspian region are presented. Monitoring studies have been conducted since the middle of the past century. The goal of the observations was to determine the implications of climate change for the habitat, profile, and state of the animated nature of the ecosystem components. In the course of the process, the station’s team observed an increase in the average annual air temperature by 2.2°C and the periodicity in the territory wetness caused by variations in the amount of precipitates. Moreover, in the period of increased wetness from 1980 to 1994, the ground water and water body levels increased, herbaceous communities and cereal crops became more yielding, and wild hoofed animals (saigas) proliferated as well. In the period of drought from 1995 to 2009, the spring melt water runoff attenuated, water bodies shoaled and dried, and dry spells repeated from year to year, which negatively affected the development of the ecosystem components. On the whole, the climate changes have not disturbed the dynamic balanced state of the natural ecosystems (e.g., yield of virgin land phytocenoses, wild animal stock); however, long dry spells have irreversibly aggravated the state of man-made forests and even caused their extinction and long-term cereal crop failures on zonal soils, which has led to unstable agricultural product outputs. The research results reveal the need to switch to adaptive fine-contour or focal farming suited most fitted for the climatic and natural condition of the region.

  • Effect of Aleppo Pine Plantations ( Pinus halepensis ) on the
           Transformation of the Semidesert Landscapes of Southeast Israel
    • Authors: S. Sprintsin; M. Shapiro; M. Sprintsin; R. Zaidenberg; E. Denisyuk
      Pages: 22 - 27
      Abstract: Anthropogenically deserted landscapes of southeastern Israel and their transformation under the influence of forest plantations are discussed. The first planting of coniferous forests in this area was performed in the middle of the last century on the stony hills of the southern part of the Hebron Highlands (Negev Plateau). The main forest-forming species of newly created forests is the Aleppo pine (Pinus halepensis). The interaction between the soil parameters of the landscape and the state of pine plantations is considered. The decisive influence of needle litter on the growth and development of coniferous forests was revealed. An approach to the assessment of the state of landscapes with coniferous forests in the normal state and forest with impaired integrity was proposed.

  • Principles and Features of the Compilation of the Red Data Book of Soils
           of the Steppe Regions (on Example of the Rostov Oblast)
    • Authors: O. V. Chernova; O. S. Bezuglova
      Pages: 28 - 37
      Abstract: Compilation of the Red Data Books of soils for the subjects of the Russian Federation will provide for conservation of natural diversity of soils in regions significantly modified by management activities. When compiling the list of the reference soils it is proposed to focus primarily on soils, which are typical for provinces of soil-ecological zoning and to identify reference soils within protected nature areas. The research of virgin soils included in the Red Data Book of the Rostov oblast showed that their characteristics can be used as reference in the course of soil monitoring. The maintenance of the fallow regime in soils promotes restoration of their humus condition. In virgin and fallow chernozems, the weighted mean humus content (for a 25-cm thick soil layer) is by 0.7–3.0% greater than that in the arable analogs. It is demonstrated that the available normative documents are not applicable for assessing the degree of pollution of regional soils with heavy metals. To fulfil this task it is proposed to use regional background concentrations established for virgin soils with similar typology and textural composition, while taking into account natural variation of characteristics.

  • Dynamics of Chemical and Microbiological Soil Properties in the
           Desert–Steppe Zone of the Southeast Russian Plain during the Second Part
           of the Holocene (4000 BC–XIII century AC)
    • Authors: N. N. Kashirskaya; T. E. Khomutova; T. V. Kuznetsova; N. I. Shishlina; A. V. Borisov
      Pages: 38 - 46
      Abstract: The results of studies of the chemical and microbiological properties of the soils buried under the barrows of the Eneolithic, Bronze, and Middle Ages periods of the southeast of the Russian Plain are presented. It was shown that the climate of the region in the Eneolithic period (4200–4100 BC) and in the Middle Ages (700 years ago) was more humid in comparison to the present time. The third millennium BC was characterized by a gradual increase of the climate aridity. Its peak was at the end of the III millennium BC. The number and biomass of microbial cells was maximal in soils buried in periods of high atmospheric humidity (4200–4100 and 3000–2800 BC) and sharply decreased during the aridization period in the second half of the III millennium BC. In general, the variability of indicators of microbocenosis conditions of desert–steppe buried soils of all ages from the burial mounds correlated with the centuries-old dynamics of the climate.

  • Geoecological Problems of Zones of Ore Mining Technogenesis in the North
           Caucasus
    • Authors: M. R. Uraskulov; I. A. Bogush; V. I. Cherkashin; I. M. Gazaliev; A. R. Yusupov
      Pages: 47 - 52
      Abstract: Centers of ore-mining technogenesis and their specific landscapes have been identified within the Karachai-Cherkess Republic and the Republic of Dagestan. Elements of the technogenic ore-mining landscape have been revealed to have a negative impact on the environment within the identified centers. It is shown that mining works are one of the main sources of ecological tension and potable fresh water pollution in highly hazardous copper-pyrite deposits. A range of mine engineering, geoecological, and social problems of the mining republics of the northern Caucasus are evaluated.

  • Assessment of the Current State of Vegetation Cover in Khentii aimag of
           Mongolia
    • Authors: I. N. Safronova; T. Yu. Karimova; L. Jargalsaikhan
      Pages: 53 - 63
      Abstract: The steppe and forest–steppe communities of Khentii aimag are classified into ten formations and formation groups. The state of steppe rangeland ecosystems has significantly declined in recent years due to a rapid increase in livestock. The pronounced changes have occurred south of the Kherlen (Kerulen) River, where grazing pressure currently exceeds their carrying capacity.

  • Effect of Arid Conditions on the Distribution of Poisonous Plants in the
           Regional Biomes of Russia
    • Authors: T. V. Dikareva; S. M. Malkhazova; V. Yu. Rumyantsev; M. S. Soldatov
      Pages: 64 - 72
      Abstract: An ecological and geographical analysis of the distribution of poisonous plants in the regional biomes of Russia and the effect of arid conditions on it are presented. On the territory of Russia, 82 of the most toxic species of vascular plants (belonging to 34 families) were identified; of them, 55 were poisonous species of the genus Aconitum. Cartographic analysis demonstrated that the smallest number of poisonous plant species (excluding species of the genus Aconitum) is confined to the plain biomes of the forest-tundra and tundra, and the largest number of such species grows in lowland steppe biomes. In the lowland desert biome and in some mountain biomes, the number of poisonous plant species is also significant but is slightly lower than in the steppe biomes. The maximal number of species of the genus Aconitum was detected in the mountainous Far Eastern biomes. Correlation analysis of the relationship between the number of plant species and climatic factors revealed the maximal correlation between the total number of poisonous plant species (excluding species of the genus Aconitum) with the average annual air temperature.

  • Rare Mammal Species in Arid and Semiarid Biomes of Russia: Distribution
           and Protection
    • Authors: L. G. Emelyanova; S. A. Tarasova
      Pages: 73 - 77
      Abstract: The distribution of thirty-two rare, endangered, and regenerated species of terrestrial mammals included in the Red Data Book of the Russian Federation that exist within the arid and semiarid biomes in Russia has been assessed. A group of rare species, which are not provided with protection at the level of the nature reserves, has been recorded. The results of surveys may be used to measure regional biodiversity and to develop standards for the protection of rare mammal species at a raised level.

  • Impact of Ecological Factors on Fishery-Biological Parameters of
           Acipenserids under Arid Conditions of a Closed Water Supply Cycle
    • Authors: M. A. Mammaev; M. M. Shikhsabekov; N. I. Rabazanov; M. S. Kurbanov; M. K. Mirzakhanov; R. M. Mammaev
      Pages: 78 - 81
      Abstract: The impact of ecological factors (abiotic and biotic) on some fishery-biological parameters is studied with the raising of acipenserids under arid conditions with a closed cycle of water supply (CCWS). The elements of a CCWS include the temperature, pH, oxygen concentration, and an artificial environment with varying oxygen supply. It was found that a significant increase in the content of a marker of oxidative stress is established in the blood of fish raised under a CCWS with an increased oxygen content by the end of experiment (four weeks). An oxygen content below 70% retards growth in the starlet, as food consumption is noticeably decreased. To obtain a high biomass in CCWS complexes, it is necessary to set the water temperature to 21–22°C in the basins of semidesert climate conditions and to have a stocking density of 60 kg/m3 for the commercial growth of sterlet.

  • Ecological intercomponent relationships in the natural solonetzic soil
           complex of the Northern Sarpinskaya Plain (Kalmykia Republic)
    • Authors: N. M. Novikova; M. V. Konyushkova; S. S. Ulanova
      Pages: 224 - 233
      Abstract: Thorough soil–geobotanical studies have been performed on a key plot located in the deserted steppe subzone of the light-chestnut–soil zone within the physicogeographical region of the Northern Sarpinskaya Lowland, Kalmykia, along a 64-m-long profile with coupled analysis of microrelief, vegetation, soils, and remote data (detailed Quickbird image). Geobotanical plots, soil trenches, and holes 1–2 m deep have been established along the profile at 1-m intervals. Analysis of the data has showed a close correlation of soils with plants communities (r = 0.72) and loose correlations of these parameters with microrelief (r = 0.42 and r = 0.36, respectively). Some species―Falcaria vulgaris, Limonium caspium, Agropyron desertorum, Stipa lessingiana, Artemisia lerchiana, Festuca valesiaca, and Tanacetum achilleifolium―are never seen on crust solonetzes; the first four species are also never found on shallow solonetzes, and the first two species are never encountered on solonetzic soils. Other species―Kochia prostrata, Artemisia pauciflora, Anabasis aphylla, and Bassia sedoides―are mainly confined to shallow and crust solonetzes and are rarely found on other soil types. The mowing data are well correlated with the normalized difference vegetation index (NDVI) (r = 0.77). The status of vegetation reflected by the NDVI value on the image is clearly determined by edaphic conditions, primarily the soil variety.

  • Changes in terrestrial ecosystems of the Lower Volga region caused by
           river flow regulation
    • Authors: Zh. V. Kuz’mina; S. E. Treshkin
      Pages: 234 - 242
      Abstract: We continued our complex ecological studies in the Lower Volga region started in 2014–2015 (Kuz’mina et al., 2015a) in order to investigate the current state of floodplain terrestrial ecosystems in changing climate conditions (Kouzmina and Treshkin, 2014a) and during regulation of the river flow. We studied typical ecosystem changes in two of four geological and geomorphological regions: western substeppe ilmens and the central part of the Volga-Akhtuba floodplain, which had not been investigated earlier (Kuz’mina et al., 2015a). We estimated changes in ecosystems and the tendencies of landscape dynamics in current conditions.

  • Saline soils and identification of salt accumulation provinces in
           Kazakhstan
    • Authors: G. T. Issanova; J. Abuduwaili; Zh. U. Mamutov; A. A. Kaldybaev; G. A. Saparov; T. A. Bazarbaeva

      Abstract: Saline soils are widespread in the southern and central parts of Kazakhstan. In these arid areas, the annual precipitation is 100–150 mm, while the evaporation exceeds the precipitation. The soils in these areas are medium and highly saline. In the framework of this study, numerous cartographic materials pertaining to the saline soils of Kazakhstan and Central Asia have been reviewed and researched. Four soil–halo–geochemical salt accumulation provinces have been identified in Kazakhstan on the basis of generalization and analysis of the available materials. The provinces differ from each other by their genesis, composition, and salt transportation patterns. ArcMap software was used as the main tool for the analysis of the soil–halo–geochemical provinces and the production of a salt accumulation map of Kazakhstan. The research of the salt accumulation geochemistry in the soils, mineral rocks, and groundwaters, salt accumulation types, and patterns of soil migration in the biosphere are the basis for the assessment of regions with irrigation activities. Therefore, the research of the saline soils and salt accumulation processes is of high practical importance.

  • Intensity of gully erosion in arid zone of Azerbaijan republic (by the
           example of the region of the Mingechaur water reservoir)
    • Authors: E. A. Gurbanov; S. A. Ganieva
      Pages: 251 - 255
      Abstract: The growth and development of gullies in the basin of the Mingechaur water reservoir, which is located in the arid zone, were studied for the first time. Soil resistance to erosion by rain water was revealed. The first experimental works on filling funnel holes and gullies were performed. Quantitative and qualitative parameters of the gully network were received. Gully erosion is spread over the entire basin area. A dissection equal to 2.0–7.0 km/km2 or greater is seen in 68.3% of the area. The gully density is also high and may rise to 15.6 gullies/km2 in places. The mean annual growth of gullies is 0.34–7.48 m in length, 0.20–2.48 m in width and 0.10–1.16 m in depth. The rate of gully development depends on the catchment area.

  • Evaluation of the restoration dynamics of the Artemisia terrae-albae
           communities in the northern part of the Aral Sea region
    • Authors: L. A. Dimeyeva; V. N. Permitina; B. M. Sultanova; K. Ussen; V. V. Lyssenko
      Pages: 256 - 264
      Abstract: This article discusses the reclamation dynamics of vegetation cover and soils after the radical phytomelioration of Artemisia terrae-albae pastures communities on brown desert solonetzic soils of the northern part of Aral Sea region. The experiment was laid in the late 1970s. Agropyron desertorum was used to create the sowing pasture. Plowing led to the destruction of natural plant communities and soils. The low germination of Agropyron seeds promoted the spread of weedy annuals, which slow the demutation of natural vegetation for 10 years. At present, the development of the vegetation cover of the laylands has reached the late-succession stage, for which the spatial and synusial structure of zonal plant communities is typical. The soils are at the stage of reclamation of morphogenetic features and properties according to the type of desert soil formation.

  • Actual state of coenopopulations of Astragalus cenralis Sheld. under
           conditions of Kuldzhuktau ridge (Kyzylkum desert)
    • Authors: Sh. U. Saribaeva; Kh. F. Shomurodov
      Pages: 265 - 270
      Abstract: The paper is devoted to an assessment of the current state of the coenotic populations of Astragalus centralis, the rarest endemic of the Kyzylkum. It is established that the studied coenopopulations of A. centralis are normal and incomplete. The cenopopulation is young in the herbage-carboxylon-wormwood and lactuca-wormwood communities and transitional in the petrophytic plant group. By the sum of the scores of the organism and population characteristics, all of the examined cenopopulations are in a pessimal condition.

  • Effect of environmental conditions on the taxonomic diversity of plant
           species in the arid region of Tabuk
    • Authors: Khalid A. Al-Mutairi
      Pages: 271 - 276
      Abstract: Arid and semiarid regions are characterized by a unique floristic composition and structural diversity of their plant communities. The goal of the present study is to investigate the effect of physical and chemical properties of soil on these characteristics of the arid region of Tabuk in Saudi Arabia. With β diversity, the variability of a plant species composition has been studied at four sites (Alwaz, Alqan, Sharma, and Zetah) of the region. Two taxonomic diversity indices, average taxonomic distinctness (Δ+) and variation in taxonomic distinctness (Λ+), have been calculated, and the effect of the environmental situation and limitations of environmental conditions on these indices have been determined. The study represents the first stage of a study intended to evaluate the taxonomic diversity of plant communities of the arid region of the Arabian Peninsula and its connection with soil properties. According to the results, anthropogenic factors (woodcutting, pasture, and urbanization) significantly influence the floristic diversity. It is proposed that urgent strategies of nature conservation be developed to protect plant habitats and prevent their destructive changes.

  • Changes in the population structure and abundance of mammals and birds in
           pasture ecosystems of the southern Minusinsk basin
    • Authors: V. A. Prelovskii
      Pages: 277 - 284
      Abstract: The data from long-term observations (from 1970 to 2012) on changes in the population structure and abundance of mammals and birds under pasture load and reserve regime conditions in the steppe zone of the southern Minusinsk basin are presented. It has been revealed that insufficient grazing or its full absence cause no less serious structural changes in animal communities than its excess. Although a decrease in pasture load leads to the recovery of the mammal and bird population in steppe ecosystems, this recovery is significantly different from native recoveries, which are based on the fallout of some stenoecic species and the introduction of eurybionts at early succession stages. An increase in the effect of pasture load on the steppe ecosystems of the basin is currently being observed again.
