Litter decomposition in Mediterranean ecosystems: Modelling the controlling role of climatic conditions and litter quality

► A new litter decay model is presented with improved climate limiting effects. ► Litter quality is assessed without traditional N-based indices. ► Model was calibrated by controlled experiments and validated with field data. ► Litter decay simulation for 7 species in 3 Mediterranean sites was highly predictive. ► Decomposition in Mediterranean region is mostly dependent on water conditions.
