The generalized large-scale maps as well as characteristic of the vegetation of three cluster sites of the new nature reserve “Altyn-Dala” (Kazakhstan) were compiled. The studied territory is located in two natural zones – steppe (sub-zone of desert steppes on light chestnut soils) and desert (subzone of northern deserts on brown soils). 7 types of vegetation – steppe, desert, forest, shrub, meadow, paludal and aquatic (aquatic macrophytes) occur on the territory of the nature reserve. Interesting and rare plant communities were recorded.

As a result of long-term (2004-2021) studies conducted in the Nakhchivan, 405 species of Anthophila belonging to 6 families and 50 genera were registered. Vertical zones and plant formations of semi-desert and mountainous ecosystems are given according to literature data. The distribution of Anthophila in these ecosystems is given based on the results of many years of scientific research. Desert and semi-desert ecosystems, limited by elevations of 700-1200 m, occupy the majority of the territory. Divided into separate plains along the left bank of the Araz river.

<em>Turkmenistan is located in the center of the Eurasian continent, far from the world ocean, in the desert and semi-desert zones of the temperate zone. The main part of its territory (80%) is occupied by the Karakum desert. As such, the majority of the country's population lives in oases, i.e. river valleys and foothills with underground streams. However, today the role of the Karakum desert in the development of various sectors of the national economy of Turkmenistan is indispensable.

AbstractThe concept of zonality is used to link well-drained mineral soils and processes along a bioclimatic gradient extending from ca. 48° to 87° S, including southernmost Chile, the subantarctic islands, and maritime and continental Antarctica. The following environmental factors decline along this gradient: mean annual temperature and precipitation and the type and number of plant species. Six pedological zones (along with representative soils) are identified along the gradient: (1) Subantarctic Forest Zone (Podzol?), (2) Subantarctic Low Tundra zone, (3) Subantarctic High Tundra Zone (Sub

Five altitudinal zones have developed on the south faced slope, including: warm temperate desert zone, mountain steppe zone, alpine meadow zone, alpine cushion vegetation zone and ice-snow zone. The demarcation elevation of the altitudinal natural zones on the south slope was extracted based on surface classification data, DEM and NDVI of the 1992 and 2016 Landsat TM/OLI data.

Four groups of indicator species have been distinguished — they enable one to identify and characterize the lichen growth zones and the boundaries between them. Changes in the boundaries of the lichen growth zones have been predicted on the basis of the results of this study. 269 lichen species have been recorded from the study area, of which 183 have been discovered or refou

Geological records have shown that the deserts east of the Helan Mountains in northern China were covered by grass during the Holocene Optimum, whereas during marine oxygen isotope stages 2 and 4 distribution of the deserts was almost the same as at present. The wide advance–retreat cycles of the deserts may have exerted an important control on grain-size changes in the loess of the Loess Plateau by altering the distance between the source and the accumulation zone of the loess.

The aim of the studies conducted in 2004-2008 was to estimate and compare the diversity of synanthropic flora of the kurgans and their microhabitats in three steppe zones in southern Ukraine. Kurgans located among large fields and pastures are very characteristic element of the Ukrainian landscape. Among the 400 visited kurgans, 81 were investigated within an area of about 20 000 km2 in the desert steppe, Pontic grass steppe and herb-grass steppe zones. The total number of species (613), as well as percentage of synanthropic species (55%) was estimated. The number of species on the kurgans in

Food insecurity (FI) is defined as “the limited or uncertain access to adequate food.” One root cause of FI is living in a food desert. FI rates among people with cystic fibrosis (CF) are higher than the general United States (US) population. There is limited data on the association between food deserts and CF health outcomes. We conducted a retrospective review of people with CF under 18 years of age at a single pediatric CF center from January to December 2019 using demographic information and CF health parameters.

The present study provides an analysis of the floristic composition, habitat types, vegetation structure and species diversity, elucidating the role of the environmental factors that affect species distribution in Kharga Oasis, Western Desert, Egypt. The vegetation was sampled from 89 permanently visited stands in 12 sites situated along N - S line transect across the oasis, and extending for about 185 km to cover as much as possible the physiognomic variation in habitats. Four main habitats were recognized and forming concentric zones (from inside to outside): farmlands and date-palm orchards

A largely boreal fauna occupies the spruce forest zone at high elevations of the Tienshan Mountains, giving way, lower down, in elm forest, to a mixed, but primarily mesic temperate fauna. Loess desert and degraded steppe at mid-elevations and in the foothills are overgrazed and have only a few species that elsewhere occur in temperate mesic and/or

Background: The prevalence of childhood obesity is higher in economically and socially deprived areas.

To address this gap, this study investigates and analyzes the morphological and chemical characteristics of 13 desert plant species in the farming–pastoral zone of the northern Tarim Basin.

Aeolian sediments accumulated along the desert-loess transition zone of the Tengger Desert include heterogeneous textures and complex component structures in their grain-size distributions (GSD). However, the sources of these aeolian sediments have not been resolved due to the lack of large reference GSD sample datasets from adjacent regions that contain various types of sediments; such datasets could be used for fingerprinting based on grain-size properties. This lack of knowledge hinders our understanding of the mechanism of aeolian dust releases in these regions and the effects of forcing o
