Global negative vegetation feedback to climate warming responses of leaf litter decomposition rates in cold biomes
Abstract Whether climate change will turn cold biomes from large long‐term carbon sinks into sources is hotly debated because of the great potential for ecosystem‐mediated feedbacks to global climate. Critical are the direction, magnitude and generality of climate responses of plant litter decomposi...
