Abstract

Soil respiration (RS) is one of the largest fluxes in the global carbon cycle. It is composed of respiration by roots and heterotrophic organisms, with each component having distinctive drivers and sensitivities and, consequently, varying feedback potential to climate change. Global drivers of the total flux of RS are widely studied and generally accepted, but our understanding of the factors governing its component fluxes lags far behind.
