Soil salinization is a growing environmental problem caused by both natural and human activities. Excessive salinity in soil suppresses growth, decreases species diversity, alters the community composition of plants; however, effect on microbial communities poorly understood. Here, we characterize along gradient Gurbantunggut Desert, Northwestern China. Microbial diversity linearly decreased with increases salinity, dissimilarity significantly increased differences. showed strong...
The means through which microbes and plants contribute to soil organic carbon (SOC) accumulation remain elusive due challenges in disentangling the complex components of SOC. Here we use amino sugars lignin phenols as tracers for microbial necromass plant components, respectively, investigate their distribution surface soils across Mongolian grasslands comparison with published data other grassland world. While decrease, increase SOC contents all examined soils, providing continental-scale...
China has experienced a dramatic change in atmospheric reactive nitrogen (Nr) emissions over the past four decades. However, it remains unclear how (N) deposition responded to increases and/or decreases Nr emissions. This study quantitatively assesses temporal and spatial variations measurements of bulk calculated dry N from 1980 2018. A long-term database (1980–2018) shows that peaked around 2000, had declined by 45% 2016–2018. Recent (based on monitoring 2011 2018) decreased 2018, with...
Belowground plant traits play important roles in diversity loss driven by atmospheric nitrogen (N) deposition. However, the way N enrichment shapes microhabitats patterning belowground and finally determines aboveground responses is poorly understood. Here, we investigated rhizosheath trait of 74 species seven N-addition simulation experiments across multiple grassland ecosystems China. We found that formation differed among functional groups contributed to changes community composition...
Aboveground biomass (AGB) is a sensitive indicator of grassland resource quality and ecological degradation. However, accurately estimating AGB at large scales to reveal long-term trends remains challenging. Here, single-factor parametric models, multi-factor non-parametric models (Random Forest) were developed for three types (alpine meadow, alpine grassland, swampy meadow) in the Bayanbuluk Grassland using MODIS satellite data environmental factors, including climate topography. A 10-fold...
Abstract A recent study (Wolf et al ., 2010) suggests that short—lived pulses of N 2 O emission during spring thaw dominate the annual budget and grazing decreases emissions thaw. To verify this we conducted year—round flux measurements from June 2010 to May 2011 in Tianshan alpine grassland central Asia. No pulse were found at management sites nitrogen addition The contribution total was small accounted for only 6.6% fluxes, with winter accounting 16.7% growing season 76.7%. difference...
Abstract It remains unclear how nitrogen (N) deposition affects soil methane (CH 4 ) uptake in semiarid and arid zones. An situ field experiment was conducted from 2010 to 2014 systematically study the effect of various N application rates (0, 10, 30 90 kg ha −1 yr on CH flux alpine grassland Tianshan Mountains. No significant influence addition found. Initially rate increased with increasing by up 11.5% 2011 then there gradual inhibition 2014. However, between-year variability very highly...
Arid areas play a significant role in the global nitrogen cycle. Dry and wet deposition of inorganic (N) species were monitored at one urban (SDS) suburban (TFS) site Urumqi semi-arid region central Asia. Atmospheric concentrations NH3, NO2, HNO3, particulate ammonium nitrate (pNH4+ pNO3−) NH4-N NO3-N precipitation showed large monthly variations averaged 7.1, 26.6, 2.4, 6.6, 2.7 µg N m−3 1.3, 1.0 mg L−1 both SDS TFS. Nitrogen dry fluxes 40.7 36.0 kg ha−1 yr−1 while 6.0 8.8 TFS,...
China is seeking to unlock its shale gas in order curb notorious urban air pollution, but robust assessment of the impact on PM2.5 pollution replacing coal with natural for winter heating lacking. Here, using a whole-city energy shift opportunity offered by substantial reductions combustion during periods Urumqi, northwest China, we conducted four-year study reveal mass concentrations and chemical components PM2.5. We found significant decline PM2.5, major soluble ions metal elements January...
Abstract. Soil respiration (Rs) is the most important source of carbon dioxide emissions from soil to atmosphere. However, it unclear what interactive response Rs would be environmental changes such as elevated precipitation, nitrogen (N) deposition and warming, especially in unique temperate desert ecosystems. To investigate this an situ field experiment was conducted Gurbantunggut Desert, northwest China, September 2014 October 2016. The results showed that precipitation N significantly...
