  • Desertification paradigm: 40 years of development and global efforts
    • Authors: I. S. Zonn; G. S. Kust; O. V. Andreeva
      Pages: 131 - 141
      Abstract: Abstract In light of the 40th anniversary of the United Nations Conference on Desertification and the 20th anniversary of the empowerment of the United Nations Convention to Combat Desertification (UNCCD), the periodization is given and the main stages in the development of international efforts to combat desertification and changes in the desertification paradigm are examined. The UNCCD initiatives, which require serious scientific study at the present stage, are reviewed, including the actively developed concept of land-degradation neutrality. A conclusion is drawn about the need to expand the mandate of the UNCCD beyond the narrow geographic scope of arid and dry regions.

  • Soil desiccation as indicator of desertification of forest–steppe
           ecosystems in the Barguzin depression
    • Authors: V. L. Ubugunov; P. D. Gunin; S. N. Bazha; Yu. I. Drobyshev; V. I. Ubugunova
      Pages: 142 - 154
      Abstract: Abstract This article presents study data on the status of plant and soil cover in the Barguzin Depression related to soil desiccation as the result of a 3-year drought, which caused the death of natural pine forests and shelterbelts composed of pine and balsam poplar. The main factors of tree death, as well as the soil conditions that favor survival under long-term air drought, have been revealed. A negative trend in the development of forest steppes under climate aridization in the North Baikal region was determined.

  • Background medical–geographical assessment of regions with high
           environmental tourism potential in the Republic of Kazakhstan
    • Authors: T. V. Dikareva; E. G. Koroleva
      Pages: 155 - 160
      Abstract: Abstract This paper is dedicated to the medical–geographical assessment of seven regions in the Republic of Kazakhstan where national parks have been designated that have potential for ecotourism development. The authors have grouped the regions by the level of population morbidity in order to identify their regional medical–geographical parameters and background (reference) characteristics. A medical–geographical map chart of the Republic of Kazakhstan showing the complex of natural focal diseases has been produced. Administrative regions with different medical–geographical risk levels have been identified. This makes it possible to develop detailed medical–environmental monitoring programs, combined with organizational and management actions in areas visited by tourists.

  • The nature of the patchiness of irrigated soils in the dry steppe zone (on
           example of the Svetloyarskaya irrigation system)
    • Authors: I. N. Gorokhova; E. I. Pankova
      Pages: 161 - 170
      Abstract: Abstract Various variants of the patchiness of irrigated soils, which are reflected on remote sensing materials and associated with the results of field research, have been analyzed on the example of the Svetloyarskaya irrigation system. The system is located on the right-bank part of the Caspian lowland within the solonetz complexes of the dry steppe. It is revealed that the reasons for the formation of the patchiness of irrigated fields fixed on remote materials are not unambiguous. During studies at the Svetloyarskaya irrigation system, it was found that the patchiness depends on the depth of the groundwater table (GWT) and the state of the field (bare soil, cropland, and layland) and can be caused by soil properties, such as primary and secondary salinization, alkalization, the carbonate content, and others.

  • Searching for benchmark soils in the steppe zone of the Trans-Ural Plateau
           to compile the Red Book of Soils
    • Authors: L. N. Plekhanova
      Pages: 171 - 177
      Abstract: Abstract A large amount of soil works on the steppe zone of the Trans-Ural Plateau has been analyzed for the purpose of finding benchmark soils to compile the Red Book of Soils. In light of the theory of basic, local, rare, and complex benchmark soils (Kliment’ev et al., 1996), the upland site on virgin soil in the center of the Stepnoe site of the Il’men State Reserve in the Ural Branch of the Russian Academy of Sciences (UB RAS), should be referred to the basic benchmark soils as the most valuable soil object in the area. The upland site is a representative example of the steppe zone of the Trans-Ural Plateau. Brown earth soils and paleourbanozems soils marked by anthropogenic impact should be considered rare soils in the region. Other rare soils include natural fossil soils—the vertical chronological series of buried soils of terraces above the flood plain and soils buried under mounds and under the ramparts of the ancient settlement of Arkaim. The entire Stepnoe site, where different soils of the region are found, is considered a complex benchmark soil site.

  • Carbon reserves in postagrogenic dry steppe soils of Western Transbaikalia
    • Authors: E. O. Chimitdorzhieva
      Pages: 178 - 183
      Abstract: Abstract New data on carbon reserves in the postagrogenic chestnut soils of Western Transbaikalia are given. Quantitative and qualitative characteristics of the formation of element reserves in these soils have been revealed. It has been shown that the ratio between organic and inorganic carbon compounds in the total carbon reserves in dry steppe ecosystems varies significantly. The element reserves are gradually restored in postagrogenic successions and become close to those in similar virgin soils.

  • Short-term exclusion of degraded pasture in the permafrost zone: aspects
           of soil microbial community
    • Authors: A. A. Danilova; G. N. Savvinov; L. D. Gavril’eva; P. P. Danilov; M. I. Ksenofontova; A. A. Petrov
      Pages: 184 - 190
      Abstract: Abstract The properties of alas soils were studied in short-term isolation (4–5 years). According to the speed of the response to the isolation of degraded pastures, components of the cryoarid–alas ecosystem form the following decreasing series: above-ground vegetation—functional range of cultivated soil microbial community—colony-forming units—underground phytomass, total mobile soil carbon, and nitrification activity. The response rates, respectively, are equal to 1, 4, 5, and over 5 years. The biodynamic features of degraded grasslands in the early years of isolation indicate that these ecosystems have a high regenerative potential. The high activity of autotrophic nitrification indicates a continuing imbalance in the circulation of substances in the isolated area.

  • Characteristics of ecological and faunistic complex of soil nematodes in
           dry-steppe landscapes in Manych valley
    • Authors: V. Y. Shmatko; L. P. Il’ina
      Pages: 191 - 202
      Abstract: Abstract The ecological and faunal similarity between different communities of soil nematodes have been established in samples of dry-steppe soils with close genetic positions and soil-forming processes. Seventyeight species of soil nematodes from 41 genera, 24 families, and seven orders have been identified in seven model plots with different habitats. It has been shown that specific features of soil nematodes communities are manifested in the species diversity and dominance of certain trophic groups and genera. On the whole, nematode fauna can be evaluated as diverse (Shannon diversity index was 1.53‒2.35) and sufficiently mature (Bongers maturity index of communities was 2.83‒4.9); our data indicates the stability and weak disturbance of the living conditions of nematodes.

  • Diversity and taxonomic composition of weeds in olive orchards in Tabuk
           Region, Saudi Arabia
    • Authors: N. A. Al Harbi
      Pages: 203 - 208
      Abstract: Abstract The introduction of weeds into the agricultural landscape is considered a major problem that threatened the cultivated plants as weeds compete with them for water, nutrients, space and light. The information about taxonomic diversity of weeds in olive orchards in Saudi Arabia is still incomplete. The present study aims to investigate the diversity patterns and taxonomic composition of the weeds in olive orchards in four sites located in Tabuk Region in the northern part of Saudi Arabia: Juraydah, Tayma, Qulaybah, and Tabuk. A total of 46 weeds species were identified from olive orchards in the four districts. The weeds communities in the Tabuk region is dominated by Pulicaria undulata, Anisosciadium lanatum, Cynodon dactylon, Emex spinosa, and Euphorbia granulata. The highest species richness of weeds was reporte in Juraydah, followed by Qulaybah, with values of 30 and 24 taxa, respectively. However, the lowest number of weed species was reported in Tayma. The highest values of Shannon-Weiner (H') and Simpson’s (1-D) indices were reported in Juraydah and Qulaybah. The diversity of species within the locations, expressed as beta diversity (β), was also measured. The olive orchards in Qulaybah and Tayma are characterized with high diversity within sites as indicated by the high values of beta diversity of 3.231 and 3.226, respectively. The diversity measures did not show significant differences among the sites (ANOVA, P > 0.05). Based on cluster analysis, olive orchards in Qualybah showed a strong relationship in the taxonomic composition of weeds with other orchards in Juraydah and Tabuk. Further studies concerning other biological and ecological aspects of weeds in the olive orchards of Saudi Arabia are urgently needed. This will facilitate the development of effective control strategies to manage the weed communities and increase the crop yield in olive orchards of Saudi Arabia.

      Abstract: Abstract New approaches using mathematical methods have been developed for estimation of the effect of undrained plain heights in delta ecosystems on soil diversity. This makes it possible to consider the effect of positive elements in the delta plain located below the zero marks that favoring the formation of local drainage. Models have been developed from the height gradients of the Terek–Kuma Lowland by the least squares method. The proposed method has revealed the soil diversity and spatial parameters characteristic of alluvialdelta coastal plains common to different continents.

  • Gypsification processes and porosity changes in soils from southern Iran
           (Jooyom region-Fars province)
    • Authors: Sahar Fazeli; Ali Abtahi; Rosa M. Poch; Hakime Abbaslou
      Pages: 80 - 91
      Abstract: Abstract Population growth are leading to intensive and extensive land use even in gypsiferous and gypseous soils which resulted in a greater demand for information of these common soils. The soils of Jooyom region located in southern Iran were studied in order to estimate the rates of soil formation processes, such as gypsum accumulation, and how they affect soil porosity. Soils have gypsum contents ranging from 0.02 to 42.1%, which increases with depth. In the field, gypsum accumulations are described as powdery nodules and vermiform gypsum. Different kinds of micromorphological pedofeatures related to gypsum are observed, which include infillings and coatings of gypsum crystals, typic nodules and crystal twins. Nodules of micrite pseudomorphs after lenticular gypsum are found, where calcite has substituted the original gypsum, which are indicators of a more arid climate in the past, followed by a more humid one. The extent, morphology and size of gypsum crystals depend on the pedogenic processes. In regard to micromorphological classification of gypsiferous soil materials, they are classified in two groups of Eogypsic and Gypsic. Soil porosity changes related to gypsum accumulation were studied and quantified by image analysis. The understanding the retention and movement of water and air in the soil; therefore, these results have a practical importance for land use and management of gypsiferous soils.

  • Geoinformation system of assessment of the susceptibility of arid area
           landscapes in the Terek-Kuma Lowland to pollution
    • Authors: I. M. Gazaliev; I. A. Idrisov; A. M. Achmedov
      Pages: 97 - 102
      Abstract: Abstract The Terek-Kuma Lowland is characterized by a wide range of anthropogenic impacts. At the same time, with respect to other arid regions of Dagestan, the anthropogenic impact on the geological environment (hydrocarbon and artesian water extraction) is of great importance. The extensive development of sandy soils and the development of animal husbandry also lead to a number of significant geoenvironmental problems. Assessment of the current geoenvironmental state of the area shows that the degree of degradation of the landscapes is small, while the possibility of their self-regeneration is at a high level.

  • Structures of small mammal populations and communities in Steppe
           ecosystems of the Caspian northwest coastal area and Eastern Mongolia
    • Authors: K. Z. Omarov
      Pages: 103 - 107
      Abstract: Abstract The responses of populations and communities of small mammals have been studied under different grazing regimens. It is shown that overgrazing and grazing restriction can have a considerable impact on the population status, demographic structure, and alspecies composition of small mammals in the Caspian northwest coast area (Nogai Steppe) and the steppes of Eastern Mongolia

  • On the conditions of maintaining the ecological balance on gas and oil
           fields
    • Authors: M.-P. B. Aytekov
      Pages: 108 - 111
      Abstract: Abstract The concentrations of radionuclides responsible for radioactive contamination have been determined in an oilfield area based on the example of the Duzlak oilfield, where a gamma survey was previously conducted. The collector and drainage channel bordering the area is shown to lack effectiveness. An evaluation was given for travertines as a construction material. Measures for isolating the salts of radioactive and other elements that accumulated in the considered area are proposed.

  • Effect of the elemental composition of soils on the reproductive organs of
           permanent crops in relation to the altitudinal gradient
    • Authors: O. K. Vlasova; G. G. Magomedov
      Pages: 112 - 115
      Abstract: Abstract The qualitative composition and quantitative content of mineral substances in the soils and fruits of Prunus armeniaca L. and Malus domestica Borkh. cultivated in the environmental conditions of the plains and foothills of central Daghestan has been estimated. The adaptation of apricot and apple trees to the natural factors of the lower foothills results in higher sugar concentrations in their fruits in comparison with trees growing on plains; the apricot and apple trees growing on lower foothills concentrate more Ca and P, while the contents of K, Na, Mg, and Cu in their fruits are reduced. Plants of the same species growing on soils with different contents of mineral substances differ by the total content of macro- and microelements in their fruits but accumulate roughly equivalent levels of P, Na, Ca, Cu, Ni, and Pb.

  • Extremophilic microbial communities of saline soils and their diversity in
           the regions of the Caspian Depression
    • Authors: E. A. Khalilova; S. Ts. Kotenko; E. A. Islammagomedova; R. Z. Gasanov; A. A. Abakarova; D. A. Aliverdieva
      Pages: 116 - 120
      Abstract: Abstract The microbial communities of alkali-saline soils and halophytes of the Caspian Depression regions have been studied for the first time. Over 40 species and forms of bacteria have been revealed. Along with a wide variety of soil microorganisms, bacteria of the genera Bacillus and Salimicrobium are the main components of the extremophilic microbial communities; their detection is one of the indices of the taxonomical structure determination, which is closely related to the ecosystem type.

  • The dynamics of mobile iodine forms in components of arid ecosystems of
           the Western Caspians
    • Authors: N. T. Gadzhimusieva; A. A. Saidieva
      Pages: 125 - 129
      Abstract: Abstract Multiyear studies on the dynamics of iodine accumulation and migration processes in the soil–plant system are summarized. The characteristics of seasonal rhythms of iodine consumption by natural vegetation and agrophytocenosis are given, and the role of soil humus in the accumulation of mobile forms of iodine are defined. Indicators of the seasonal cycle and the dynamics of the outflow of mobile element forms from soil to plant vegetative organs are described. The reserves of total iodine forms indicate potential enrichment with mobile forms and the elimination of iodine deficiency of the soils of the Western Caspian Sea region.
