Desert Steppe Ecosystem

2020
This chapter focuses on Chinese desert steppe ecosystems. It introduces in brief the areal extent and provincially based distribution of this ecosystem type, simply discusses the relevant physical features and climatic characteristics at a regional scale, elaborates in great detail upon the flora, fauna, and microflora composing the various desert ...

Haloalkaliphilic actinomycetes in soils of Mongolian desert steppes

Biology Bulletin, 2007
The abundance of actinomycetes isolated from the soils of Mongolian desert steppes varies from several thousand to hundreds of thousands of CFU/g soil, depending on soil type and isolation medium. Eight actinomycete genera have been found in these soils: Streptomyces, Micromonospora, Saccharopolyspora, Actinomadura, Microtetraspora, Thermomonospora ...

Validation of Soil Moisture Retrieval in Desert Steppe Area

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Surface soil moisture (SM) plays a decisive function during the grassland degradation and restoration process. In this paper, a surface soil moisture retrieval model in desert steppe area with improved spatial resolution is established using diurnal temperature range (DTR) and Normalized Difference Vegetation Index (NDVI).

NDVI for Monitoring of the State of Steppe and Desert Ecosystems of the Gobi

Arid Ecosystems, 2019
The current state of the dry-steppe, desert-steppe, mountain-steppe, and desert ecosystems of the Gobi Desert (Mongolia) has been studied. In the dry steppes and steppe deserts, not only is there a decrease in the phytocenotic indicators of plant communities and deterioration of the state of dominants, but also a change in their composition has been ...

Effects of precipitation and grazing on the diversity and productivity of desert steppe

Land Degradation & Development, 2023
AbstractThe variability of annual precipitation and grazing are primary drivers shaping the structure and function of plant communities in grasslands. Yet it remains unclear on a mechanistic understanding of how annual precipitation and grazing affect the plant community structure, function, and their linkage via direct or indirect pathways.

Steppe and desert in the light of lichen vegetation.

Proceedings of the Linnean Society of London, 1937
Summary. .1. Bare places of the desert bear a rich cover of lower plants, i.e. of lichens. 2. Lichens may be of great use in defining the floristic characteristic of steppe and desert. 3. With the help of lichens it is possible to prove the identity of the desert in Egypt and in Southern Palestine. 4. A similarity of the desert

To Desert and Steppe

2006
The vast reaches of central Asia are redolent with history, with stirring tales of Marco Polo’s epic journeys and all the romance of the Silk Road, an arduous caravan route that connected Asia and the West for hundreds of years. The archaeology of both central Asia and the Silk Road has yet to reveal all their secrets, for the area presents formidable ...

The steppes and deserts of the Xizang Plateau (Tibet)

Vegetatio, 1988
The Xizang Plateau (Tibet) covers a vast area over 4 000 m with a severe environment. Steppes and deserts are widely distributed on the plateau to the west of 91.5°E. Poaceae, Asteraceae, Fabaceae and Cyperaceae are the most important families in the composition of steppe communities.

Ecohydrological influences of biocrusts and their pathways in a desert steppe ecosystem

Ecohydrology, 2023
AbstractBiological soil crusts (biocrusts) are a prevalent form of organic cover in drylands across the world, and they play a crucial role in shaping the ecohydrological processes and functioning of dryland ecosystems. However, in desert steppe ecosystems, the ecohydrological influences of biocrusts and their pathways have not yet been thoroughly ...

Spatial distribution of shrubs and perennial plants under grazing disturbance in the desert steppe of Inner Mongolia

Global Ecology and Conservation
The desert steppe is unique as a transition zone from the steppe to the desert of the Eurasian Steppe. The spatial distribution of shrubs and perennial plants has changed due to long-term disturbance caused by overgrazing in the ecosystem.
