Drought and biomass production in natural grassland ecosystems
Original language description
Global climate change is predicted to alter growing season precipitation patterns, potentially reducing total amounts of growing season rainfall and redistributing precipitation into fewer but larger individual events. Such changes may affect numerous soil, plant, and ecosystem properties in grasslands. A five-year field study with regulated amount of rainfall was executed in different types of grasslands (dry Festuca, wet Cirsium and mountain Nardus grasslands) in three different regions in the Czech Republic. Three simulated precipitation treatments were applied: reduced rainfall by 50% (dry), increased rainfall by 50% (wet), and natural rainfall of the current growing season (ambient). Our findings indicate that water availability regulates grassland responses to accumulation of below-ground biomass, which can affect the global carbon cycle. Our results also show a substantial effect of decreased precipitation in reducing root dry mass. These data also confirmed our previous finding
