Increased microbial carbon use efficiency upon abrupt permafrost thaw

Proceedings of the National Academy of Sciences, Volume 122, number 33, August 2025.
Significant carbon use efficiency (CUE) describes the carbon (C) report preserved in biomass on the absorption of C. Despite its importance in determining the loss and formation of the soil C, how the microbial signal would change during the decline of pergialisol remains badly …
