Carbon (C) and nitrogen (N) are closely coupled to regulate the cycle of soil organic carbon (SOC) and its feedback to climate change in terrestrial ecosystem. However, the response of SOC content to N input in different soil types on time scales is still less understood. Here, we did a meta-analysis by collecting global farmland data across 60 yea...
Understanding the effects of changing climate and long-term human activities on soil organic carbon (SOC) and the mediating roles of microorganisms is critical to maintain soil C stability in agricultural ecosystem. Here, we took samples from a long-term soil transplantation experiment, in which large transects of Mollisol soil in a cold temperate...
Background
Soil methanogens participate in complex interactions, which determine the community structures and functions. Studies continue to seek the coexistence patterns of soil methanogens, influencing factors and the contribution to methane (CH4) production, which are regulated primarily by species interactions, and the functional significance o...
Aim
The β‐diversity of plants and animals generally decreases with increasing latitudes. Here, we tested whether this relationship also holds for soil microbes at both functional and taxonomic levels.
Location
China.
Time period
Between June and October 2013.
Major taxa studied
Soil archaea, bacteria, and functional genes.
Methods
We used a spa...
Biological nitrogen fixation is an important process to reduce fertilizer application in agriculture ecosystem. However, with accelerated climate warming, it is still unknown how diazotrophs (nitrogen fixing microorganisms) succeed and assemble in long-term field-based experiment. By southward translocating arable Mollisols to a warm-temperate regi...
Global warming poses an unprecedented threat to agroecosystems. Although temperature increases are more pronounced during winter than in other seasons, the impact of winter warming on crop biomass carbon has not been elucidated. Here we integrate global observational data with a decade-long field experiment to uncover a significant negative correla...
Soil organic carbon (SOC) is the largest carbon pool in terrestrial ecosystems and plays a crucial role in mitigating climate change and enhancing soil productivity. Microbial-derived carbon (MDC) is the main component of the persistent SOC pool. However, current formulas used to estimate the proportional contribution of MDC are plagued by uncertai...
Soil microbes are essential for regulating carbon stocks under climate change. However, the uncertainty surrounding how microbial temperature responses control carbon losses under warming conditions highlights a significant gap in our climate change models. To address this issue, we conducted a fine-scale analysis of soil organic carbon composition...
Compelling evidence has shown that wetland methane emissions are more temperature dependent than carbon dioxide emissions across diverse hydrologic conditions. However, the availability of carbon substrates, which ultimately determines microbial carbon metabolism, has not been adequately accounted for. By combining a global database and a continent...
Studying the functional heterogeneity of soil microorganisms at different spatial scales and linking it to soil carbon mineralization is crucial for predicting the response of soil carbon stability to environmental changes and human disturbance. Here, a total of 429 soil samples were collected from typical paddy fields in China, and the bacterial a...
Soil microbes are considered the second genome of plants. Understanding the distribution and network of aluminum (Al)-tolerant microorganisms is helpful to alleviate Al toxicity to plants in acidic soils. Here, we examined soluble Al³1 and bacterial communities carrying Al resistance genes in paddy soils with a soil pH range of 3.6 to 8.7. In the a...

Methane (CH₄) is regarded as an important greenhouse gas, with a global warming potential 25 times higher than CO₂. Soil methanogens – organisms that generate CH₄ in the soil – participate in complex interactions, which determine the community structures and functions. Better understa...
