Soil organic carbon (SOC) is the largest terrestrial C reservoir on Earth, which plays a critical role in climate regulation. While global warming is a defining feature of anthropogenic climate change, its interactive effects with other global change drivers on the content of SOC remain unclear. For this study we conducted a global meta‐analysis of 2349 observations from 363 studies, which revealed that warming alone reduced S...

The frequency and intensity of droughts worldwide are challenging the conservation of soil organic carbon (SOC) pool. Microbial necromass is a key component of SOC, but how it responds to drought at specific soil depths remains largely unknown. Here, we conducted a 3‐year field experiment in a forest plantation to investigate the impacts of drought intensities under three treatments (ambient control [CK], moderate drought [30%...

Carbon (C):nitrogen (N):phosphorus (P) stoichiometry in plants, soils, and microbial biomass influences productivity and nutrient cycling in terrestrial ecosystems. Anthropogenic inputs of P to ecosystems are increasing; however, our understanding of the impacts of P addition on terrestrial ecosystem C:N:P ratios remains elusive. By conducting a meta‐analysis with 1413 paired observations from 121 publications, we showed that...

Aim The aim was to test whether the responses of C:N:P stoichiometry in plant–soil–microorganism systems to precipitation changes support the prediction of the double asymmetry model, which predicts ecological processes (i.e. aboveground productivity, soil microbial community, and soil respiration) are more sensitive to increased precipitation (R+) than decreased precipitation (R−) under normal precipitation changes, whereas m...

Aims Soil microbes are key to myriad processes in terrestrial ecosystems. Elevated CO 2 represents a dominant driver of global climate change; however, it remains unclear to what extent elevated CO 2 impacts soil microbial communities at ecosystem and global scales. Here, we sought to address the following questions: (a) Do the compositions of microbial communities shift from K ‐ to r ‐strategists under elevated CO 2 ? (b) Wha...
