英文摘要	With approximately 60 Pg of carbon (C) released as CO2 annually, the decomposition of dead organic matter feeds the major terrestrial global CO2 flux to the atmosphere. Macroclimate control over this critical C flux facilitates the parametrization of the C cycle in Earth system models and the understanding of climate change effects on the global C balance. Yet, the long-standing paradigm of climate control was recently challenged by the so far underestimated environmental heterogeneity at local scales, questioning the conceptual framework of thousands of decomposition studies and accuracy of current predictive models. Using three complementary decomposition experiments at a European scale, we showed that macroclimate and litter characteristics largely control plant litter decomposition, reaffirming the role of macroclimate as an integrative decomposition driver through direct environmental control and by influencing co-evolving local plant and decomposer communities. Neglecting this latter indirect effect, commonly used standard litter types overrated micro-environmental control and failed to predict local decomposition of plot-specific litter. Our data help clarify a key question on the regulation of the global C cycle by identifying the relative role of control factors over decomposition and the scales at which they matter and by highlighting sources of confusion in the literature.
