1. Climate change will reduce litter decomposition and mineralisation rates, both directly through changes in environmental factors, and indirectly through changes in species composition with increasing dominance of drought-tolerant species sharing traits that negatively affect decomposition processes.
2. Reduced litter decomposition and mineralization rates negatively affect nitrogen availability in soil, but increase carbon-sequestration.3. Resistance against these climate change effects will be higher in diverse plant communities than in species-poor communities.
