• W4281252912 abstract "Predicted climate change extremes, such as severe or prolonged drought, may considerably impact carbon (C) and nitrogen (N) cycling in water-limited ecosystems. However, we lack a clear and mechanistic understanding of how extreme climate change events impact ecosystem processes belowground. This study investigates the effects of five years of reoccurring extreme growing season drought (66% reduction, extreme drought treatment) and two-month delay in monsoon precipitation (delayed monsoon treatment) on belowground productivity and biogeochemistry in two geographically adjacent semi-arid grasslands: Chihuahuan Desert grassland dominated by Bouteloua eriopoda and Great Plains grassland dominated by B. gracilis. After five years, extreme drought reduced belowground net primary productivity (BNPP) in the Chihuahuan Desert grassland but not in the Great Plains grassland. Across both grasslands, extreme drought increased soil pH and available soil nutrients nitrate and phosphate. The delayed monsoon treatment reduced BNPP in both grasslands. However, while available soil nitrate decreased in the Chihuahuan Desert grassland, the delayed monsoon treatment overall had little effect on soil ecosystem properties. Extreme drought and delayed monsoon treatments did not significantly impact soil microbial biomass, exoenzyme potentials, or soil C stocks relative to ambient conditions. Our study demonstrates that soil microbial biomass and exoenzyme activity in semi-arid grasslands are resistant to five years of extreme and prolonged growing season drought despite changes to soil moisture, belowground productivity, soil pH, and nutrient availability. Figure illustrating the effects of 5 years of extreme growing season drought (b) and delayed monsoon timing (c) on belowground productivity and biogeochemistry in two geographically adjacent semi-arid grasslands. Panel (a) represents ambient conditions and the two grassland sites within all panels; the blue grama (left side) represents the Great Plains grassland site, and the black grama (right side) represents the Chihuahuan Desert grassland site. In general, we found that, relative to the ambient treatment, the extreme drought and delayed monsoon treatments had few effects on soil microbial variables, including soil microbial biomass and exoenzyme potentials, and had no effect on soil C stocks (no effect = brown boxes). The lack of effects on microbial variables is despite reductions in BNPP (negative effects = red boxes with “- “) and impacts on biogeochemical variables, such as increased soil pH and available soil nutrients (positive effects = blue boxes with “+“). • Extreme and prolonged growing season drought reduces belowground primary productivity. • Microbial biomass and enzymes unaltered by severe or prolonged growing season drought. • Belowground properties are more sensitive to extreme drought than seasonality changes." @default.
