英文摘要	Soil microorganisms are known to significantly contribute to climate change through soil carbon (C) cycle feedbacks. However, it is challenging to incorporate these feedbacks into predictions of future patterns of terrestrial C cycling, largely because of the vast diversity of soil microorganisms and their responses to environmental conditions. Here, we show that the composition of the bacterial community can provide information about the microbial community-level thermal response (MCTR), which drives ecosystem-scale soil C-climate feedbacks. The dominant taxa from 169 sites representing a gradient from tropical to boreal forest mainly belonged to the phyla Actinobacteria and Acidobacteria. Moreover, we show that the MCTR in warm biomes and acidic soils was linked primarily to bacteria, whereas the MCTR in cold biomes and alkaline soils was primarily associated with fungi. Our results provide strong empirical evidence of linkages between microbial composition and the MCTR across a wide range of forests, and suggest the importance of specific microorganisms in regulating soil C-climate feedbacks. © 2021 Science China Press
