Responses of soil respiration and its components to drought stress

Climate change is likely to increase both intensity and frequency of drought stress. The responses of soil respiration (Rs) and its components (root respiration, Rr; mycorrhizal respiration, Rm; and heterotrophic respiration, Rh) to drought stress can be different. This work aims to review the recent and current literature about the variations in Rs during the period of drought stress, to explore potential coupling processes and mechanisms between Rs and driving factors in the context of global climate change.
