Abstract The relationship between plant aboveground biomass and diversity typically follows a unimodal pattern, showing positive correlation in resource‐poor habitats negative resource‐rich environments. Precipitation is crucial resource for both terrestrial ecosystems. However, the impact of precipitation changes on remains unclear. We conduct water addition field experiment semiarid grassland identify species richness under ambient conditions. Water delays declining phase this curve shift it upward compared to Our meta‐analysis experiments conducted across major biomes worldwide (grassland, shrubland, desert, forest) supports finding, while reduction does not alter biomass–diversity relationship. increases all climate but only arid climate. Similarly, decreases reduces Species dry subhumid humid change significantly. Furthermore, our shows that decreasing soil inorganic nitrogen levels. increase one resource, such as water, leads scarcity another, nutrient, thus postponing observed habitats. research contributes predicting changing conditions highlights complex interplay availability, nutrient level, diversity.

Nutrient addition, particularly nitrogen, often increases plant aboveground biomass but causes species loss. Asymmetric competition for light is frequently assumed to explain the biomass-driven However, it remains unclear whether other factors such as water can also play a role. Increased leaf area following nitrogen addition and warming may increase transpiration cause limitation, leading decline in diversity. To test this, we conducted field measurements grassland community exposed warming. We found that and/or significantly increased reduced richness. Water prevented loss either nitrogen-enriched or warmed treatments, while partially mitigated treatment both temperature nitrogen. These findings thus strongly suggest limitation be an important driver of after when soil moisture limiting. This result further supported by meta-analysis published studies across grasslands worldwide. Our study indicates richness future greatest under scenario increasing deposition, decreasing precipitation.

The world’s grasslands are under increasing threat of degradation. Given the potential for multiple drivers decline, precise diagnosis degradation is best achieved by comparison with a local, sustainable grassland community. Comparisons this kind becoming increasingly common regional plant communities, but these studies largely overlook interactions between soil responses to system and effective functioning seed bank. Surveys have revealed that only around 5% include information on bank composition no one aspect community structure features across all studies. Furthermore, majority provide ground coverage, sward biomass or species diversity in subcommunity, very few including health how changes environment could drive further deterioration size, We consider likely exacerbate rather than mitigate impacts function, leading spiral absence timely targeted intervention. propose improvements future seeking diagnose quantify

Residual films (RFs) disrupt the normal migration and distribution of water, salts nutrients in soil, posing a significant threat to sustainable development agriculture food security. The effect complexity RF on soil water-salt crop growth result conflicting findings previous studies. Systematic quantitative exploration thresholds is great significanse. Focusing influence agriculture, this study conducted meta-analysis 44 peer-reviewed studies using 1514 moisture data points, 568 salt 312 yield points. results showed: reduced by 2.62 %, decreased 11.72 increased salinity 4.09 %. These adverse effects were exacerbated environments with an average annual evapotranspiration (AAE) > 1800 mm, precipitation (AAP) < 500 temperature (AAT) 10°C. Although degradable film (DF) outperformed ordinary ones, no difference was observed between RFs varying thicknesses (p 0.05). levels 0 225 kg·ha

Abstract Quantifying terrestrial carbon (C) sequestration potential is crucial for climate change mitigation and achieving C neutrality. Ecosystem manipulative experiments (EMEs) provide valuable in situ assessments of dynamics under global change. Although EMEs have expanded rapidly China, their current state role elucidating spatial drivers the country's sink responses to major factors remain underexplored. This study systematically reviewed 1140 publications on Chinese EMEs, compiling a dataset net primary productivity (NPP) ecosystem (NEP). We identified 558 China since 1991, marked by two phases: (1) preliminary stage (1991–2004) (2) exponential growth (2005–present). Most focused grasslands, with limited emphasis CO 2 enrichment studies Northwest China. Our findings revealed that China's ecosystems serve as significant (positive NEP), strength positively associated temperature, soil clay, silt, nitrogen (N) contents, negatively sand content bulk density. Optimal conditions NPP NEP were observed at precipitation levels 850–1176 mm pH between 6.5 7.0. Elevated stimulated when combined N addition, particularly organic N, effects varied temperature texture (clay, contents). Warming impacts differed facility type, reducing wetlands open‐top chambers. Combined warming water or addition generally increased NEP, while coupling it reduced caused declines. above 1.5°C often had adverse impacts. Both responded nonlinearly precipitation, exhibiting negative asymmetry anomalies. Nitrogen consistently influenced application rates, frequency, duration, pH. Additive common. To improve our understanding feedbacks anthropogenic changes, future research should focus long‐term, multifactor mature forests wetlands, aiding pursuit net‐zero targets.
