Final Report Abstract

Greater intra-annual rainfall variability is predicted for many regions on earth. Within this project, we analyzed the effects of four different precipitation regimes varying in distribution (frequency) and seasonality interacting with four different land use regimes varying in frequency and magnitude on productivity and diversity of natural grassland communities in Central Europe. We addressed above and below ground biomass production and protein content of selected species and monitored relative species abundance and diversity of plant communities. More variability in precipitation regimes proved to have significant effects on biomass production, feed value and plant species interactions.
