Abstract Intensification of the Earth's hydrological cycle amplifies interannual variability precipitation, which will significantly impact terrestrial carbon (C) cycle. However, it is still unknown whether previously observed relationship between soil respiration ( R s ) and precipitation remains applicable under extreme change. By analyzing observations from a much larger dataset field experiments (248 published papers including 151 grassland studies 97 forest studies) across wider range...
Abstract Nitrogen (N) deposition and land‐use practice (e.g. mowing) could have profound effects on soil respiration. However, the changes in other ecosystem components, such as plant functional groups ( PFG s), may control carbon (C) efflux response to long term global change. A 10‐year (2005–2014) field experiment was conducted with both N addition (10 g m −2 year −1 ) mowing (once a year) northern Chinese temperate grassland. We collected continuous data respiration over 10 years...
Based on a 6-year field trial in temperate steppe Inner Mongolia, we investigated the effects of nitrogen (N) and phosphorus (P) fertilization mowing abundance community compositions ammonia-oxidizing Bacteria (AOB) Archaea (AOA) upon early (May) peak (August) plant growth using quantitative PCR (qPCR), terminal-restriction fragment length polymorphism (T-RFLP), cloning sequencing. The results showed that N changed AOB composition increased both May August, but significantly decreased AOA...
Abstract Extreme precipitation events are predicted to occur more frequently and will have significant influences on terrestrial ecosystem carbon (C) cycling in the future. However, response patterns of soil respiration changes remain uncertain ecosystems. A field experiment with seven treatments (i.e. from −60% +60% ambient form a drought wet gradient) was conducted over three growing seasons (2010–2012) semiarid temperate steppe Northern China. Results showed nonlinear pattern along...
Fusarium stalk rot (FSR), a devastating soil-borne disease caused by species, severely threatens global maize production through yield losses and mycotoxin contamination. Bacillus subtilis, plant growth-promoting rhizobacterium (PGPR), has shown potential as biocontrol agent against pathogens, but its efficacy mechanisms FSR remain poorly understood. In this study, an identified strain of B. subtilis A3 was introduced to study biological control corn rot. The bacteriostatic stability the...
The Kekexili region of the Tibetan Plateau has become warmer and wetter since 1960s, resulting in a significant expansion Zhuonai Lake (+0.46 km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /year, p <; 0.05) before an outburst flood event occurred on September 15, 2011, mapped by Chinese Huanjing (HJ)-A/B satellites with two-day revisit ability 360-km orbit swath. direct cause was due to relatively heavy precipitation from May...
Abstract Third Pole natural cascade alpine lakes (NCALs) are exceptionally sensitive to climate change, yet the underlying cryosphere-hydrological processes and associated societal impacts largely unknown. Here, with a state-of-the-art cryosphere-hydrology-lake-dam model, we quantified notable high-mountain Hoh-Xil NCALs basin (including Lakes Zonag, Kusai, Hedin Noel, Yanhu, from upstream downstream) formed by Lake Zonag outburst in September 2011. We demonstrate that long-term increased...
Abstract Changes in water and nitrogen (N) availability due to climate change atmospheric N deposition could have significant effects on soil respiration, a major pathway of carbon (C) loss from terrestrial ecosystems. A manipulative experiment simulating increased precipitation has been conducted for 9 years (2005–2013) semiarid grassland Mongolian Plateau, China. Increased addition interactively affect respiration through the years. The interactions demonstrated that weakened...
Abstract vegetation is a sensitive indicator of climate change. The spatial-temporal dynamic changes cover and aboveground biomass their relationship with factors in Qaidam Basin recent 13 years were studied by using index. results are as follows: (1) the total area increased from 2002 to 2015, growth rate 644.11km2/a (R2 = 0.4919). In 14 years, change has been increasing → decreasing decreasing, among which continuously 2009 2012; (2) During period 2002-2015, each level coverage showed an...
Plateau lakes are sensitive indicators of climate change. This study used multi-source satellite data to monitor the temporal and spatial dynamics lake area in Qaidam Basin. There sults showed that Basin were different conditions. The core basin affected by human activities achanges drastically. around less could better reflect In past 50 years, has generally been warm humid. annual mean temperature increases from east west tends decrease; precipitation was just opposite temperature, rate...
Abstract In order to monitor the temporal and spatial dynamics of vegetation in Qaidam Basin, ground-based biomass model basin was established by using ground measurements data during 2016-2018 NDVI MOD13Q1: Y=0.0002X2-0.863X+2052.4(R 2 =0.7656, P<0.01), this estimate long-term aboveground set basin. Above-ground is mainly low-yield less than 1500 kg/hm , followed 1500-3000 area which accounts for 10% total area, other levels very small, only scattered, High-yield greater 6000 distributed...
Silvicultural practices are essential for alleviating the impacts of drought on health and structure forest ecosystem. However, it is yet uncertain how management together would affect soil carbon (C) cycling. Therefore, we carried out a field manipulative experiment to examine influences decreased precipitation (-25% -50%) thinning respiration (Rs) its heterotrophic autotrophic components (Rh Ra) in coniferous-broadleaved mixed warm temperate-subtropical climate transition zone Central...
As a big province which owns many grasslands, the potential carbon sequestration of Qinghai is very great. The strong (A2a) and weak (B2a) scenarios in global climate warming drying scenarios, Province opposite to trends, taking on warm trend; main subject grassland alpine tundra categories, accounting for total area 75.69%, annual 87.22% province. compared with nearly 50 years (1950–2000) ,the will show decrease trend Province, increasing forest area, be reduced respectively by 30.71%...
