Atmospheric deposition of nitrogen(N)plays a significant role in shaping the structure and functioning of various terrestrial ecosystems ***,the magnitude of N deposition on grassland ecosystems in Central Asia still remains highly *** this study,a multi-data approach was adopted to analyze the distribution and amplitude of N deposition effects in Central Asia from 1979 to 2014 using a process-based denitrification decomposition(DNDC)*** showed that total vegetation carbon(C)in Central Asia was 0.35(±0.09)Pg C/a and the averaged water stress index(WSI)was 0.20(±0.02)for the whole *** N deposition led to an increase in the vegetation C of 65.56(±83.03)Tg C and slightly decreased water stress in Central *** of this study will expand both our understanding and predictive capacity of C characteristics under future increases in N deposition,and also serve as a valuable reference for decision-making regarding water resources management and climate change mitigation in arid and semi-arid areas globally.

Arbuscular mycorrhizal fungi(AMF)are universally mutualistic symbionts that colonize the fine roots of most vascular ***,the biogeographical patterns and driving factors of AMF diversity of plant roots in grasslands are not well *** this study,we used high-throughput sequencing techniques and bioinformatics to evaluate the AMF richness of 333 individual plant roots in 21 natural grassland ecosystems in northern China,including the Loess Plateau(LP),the Mongolian Plateau(MP),and the Tibetan Plateau(TP).The AMF richness showed a significant parabolic trend with increasing *** regional situations,the AMF richness in the grasslands of the MP(60.4±1.47)was significantly higher than those of the LP(46.4±1.43)and TP(44.3±1.64).Plant traits(including plant families,genera,and functional groups)explained the most variation in the AMF richness across China's grasslands,followed by energy and water;soil properties had the least *** results showed the biogeographical patterns of the AMF richness and the underlying dominant factors,providing synthetic data compilation and analyses in the AMF diversity in China's grasslands.
