Abstract

Microbial carbon use efficiency (CUE) is a crucial parameter for characterizing soil organic carbon (C) dynamics. However, the response of microbial CUE to land-use change and the underlying mechanisms remain unclear. In this study, we estimated CUE using a biogeochemical equilibrium model across three paired natural and anthropogenic land-use systems. We found that the conversion from natural to anthropogenic ecosystems reduces CUE and increases microbial C limitation. Through a combination of variation partitioning modeling, random forest analysis, and partial least squares path modeling, we showed that elemental stoichiometry was up to 4.2 times more important in determining CUE than soil physiochemical properties and microbial physiological characteristics, and the microbial C to nitrogen ratio had a key positive effect on CUE. Therefore, the role of microbial eco-physiological traits (e.g., fungi:bacteria) in improving CUE and thus mitigating C loss from anthropogenic ecosystems requires consideration in land management strategies for C sequestration.
