Nitrogen deposition differentially regulates the sensitivity of gross primary productivity to extreme drought versus wetnessNARA Subscribed
Global hydroclimatic variability is increasing with more frequent extreme dry and wet years, severely destabilizing terrestrial ecosystem productivity. However, what regulates the consequence of precipitation extremes on productivity remains unclear. Based on a 9‐year field manipulation experiment on the Qinghai–Tibetan Plateau, we found that the responses of gross primary productivity (GPP) to extreme drought and wetness were...
Plant‐ and microbially derived carbon (C) are the two major sources of soil organic matter (SOM), and their ratio impacts SOM composition, accumulation, stability, and turnover. The contributions of and the key factors defining the plant and microbial C in SOM along the soil profile are not well known. By leveraging nuclear magnetic resonance spectroscopy and biomarker analysis, we analyzed the plant and microbial C in three s...

Vegetation type controls root turnover in global grasslandsNARA Subscribed
Aim Root turnover is an important process determining carbon and nutrient cycling in terrestrial ecosystems. It is an established fact that root turnover is jointly regulated by climatic, edaphic and biotic factors. However, the relative importance of these forces in determining the global patterns of root turnover time is far from clear. Location Global. Time period 1946–2017. Major taxa studied Grasslands. Methods We compile...
Regional variation in the temperature sensitivity of soil organic matter decomposition in China's forests and grasslandsNARA Subscribed
How to assess the temperature sensitivity ( Q 10 ) of soil organic matter ( SOM ) decomposition and its regional variation with high accuracy is one of the largest uncertainties in determining the intensity and direction of the global carbon (C) cycle in response to climate change. In this study, we collected a series of soils from 22 forest sites and 30 grassland sites across China to explore regional variation in Q 10 and it...
Nitrogen (N) deposition is impacting the services that ecosystems provide to humanity. However, the mechanisms determining impacts on the N cycle are not fully understood. To explore the mechanistic underpinnings of N impacts on N cycle processes, we reviewed and synthesised recent progress in ecosystem N research through empirical studies, conceptual analysis and model simulations. Experimental and observational studies have...
