Replanted Calligonum caput-medusae saplings in the Tarim River watershed face short-term and frequent herbivory by goats, which can result in either growth inhibition or stimulation. The effects of herbivory on shrub saplings are unclear. We simulated herbivory with clipping to test two hypotheses. We hypothesized that (1) moderate herbivory may positively(More)
Based on the observed data from 51 meteorological stations during the period from 1958 to 2012 in Xinjiang, China, we investigated the complexity of temperature dynamics from the temporal and spatial perspectives by using a comprehensive approach including the correlation dimension (CD), classical statistics, and geostatistics. The main conclusions are as(More)
Investigation of the water sources used by trees of different ages is essential to formulate a conservation strategy for the riparian tree, P. euphratica. This study addressed the contributions of different potential water sources to P. euphratica based on levels of stable oxygen and hydrogen isotopes (δ18O, δ2H) in the xylem of different aged P.(More)

Vegetation dynamics are very sensitive to climate change, especially in arid and semiarid regions. The Tarim River Basin, the largest and the most arid basin in northwest China, is a typically closed, independent, and self-balanced hydrological system. In this study, the Mann–Kendall trend test, partial correlation analysis, and gray relation analysis were(More)
This Article contains a typographical error in the Results section under subheading 'Terrestrial total water storage variations'. " This suggests that the water tower loss in Central Asia has been about − 2.23 × 10 8 m 3 /a over the past 10 years.

Different groundwater conditions affect leaf hydraulic conductance and leaf pressure–volume parameters in Populus euphratica at the extremely arid zone in the northwest of China. Efficient water transport inside leaves constitutes a major determinant of plant function, especially in drought-stressed plants. The previous researches have reported the(More)
Understanding runoff generation and dynamics is the basis for water resource management, while water isotopic ratios are a potential tool for studying the mechanism on a large scale. In this paper, spatial variations of δ 18 O and δD of river water and their sources within a large region of the Tarim River were investigated. The results showed obvious(More)
The Tienshan Mountains, with its status as "water tower", is the main water source and ecological barrier in Central Asia. The rapid warming affected precipitation amounts and fraction as well as the original glacier/snowmelt water processes, thereby affecting the runoff and water storage. The ratio of snowfall to precipitation (S/P) experienced a downward(More)
