BACKGROUND Although semi-arid and arid regions account for about 40% of terrestrial surface of the Earth and contain approximately 10% of the global soil organic carbon stock, our understanding of soil organic carbon dynamics in these regions is limited. METHODOLOGY/PRINCIPAL FINDINGS A field experiment was conducted to compare soil organic carbon dynamics between a perennial grass community ...

Enclosure is commonly used in the restoration of degraded grasslands. However, effects enclosure on grassland plant and soil remain controversial, particularly deserts. To assess desert plants properties, using high throughput sequencing, differences between were systematically analyzed before after construction. The organic carbon, total nitrogen phosphorus contents three flora increased decre...

Long-term protection of arid ecosystems changes the vegetation and soil structures. The quantification aboveground biomass carbon content are among principal indicators to evaluate these changes. Most methods used quantify parameters costly, time consuming destructive. In this paper, two non-destructive were compared: digital image processing biometric measurements. Aboveground five perennial s...

The article presents the phytocenotic characteristics of Kalidium capsicum, Halocnemum strobilaceum pasture variety (PV), which is a part type. described type widespread in central Karakalpak Ustyurt. on wet and plump salt marshes, with Haloxylon ammodendron, H. gypsum participation Reaumuria songarica, caspicum cones temporary watercourses combination Anabasis salsa located Kungrad district, g...

black saxaul (haloxylon aphyllum) is one of the best options for rehabilitating drought affected desert lands. the species is remarkably adapted to the central dry environment ofiran and a major source of raising pasture productivity of the areas. progenies of 25 randomly selected black saxaul trees from four populations of the species were studied in a randomized complete block design with thr...

The study of plant photosynthesis under different degrees drought stress can provide a deeper understanding the mechanism resistance. In Taklimakan Desert, saline groundwater is only local water source with regard to shelterbelt construction and determines growth photosynthetic changes. this study, daily dynamics gas exchange parameters their responses photon flux density at three irrigation le...
