Title : Effects of experimental drought on soil respiration and radiocarbon efflux from a temperate forest soil
Journal : Global Change Biology
Comment : Prolonged drought periods in 1995, 1998, and 1999 at the Harvard Forest resulted in decreased soil respiration rates in the uplands, particularly once soil moisture contents decreased below about -150 kPa. In contrast, wetland respiration increased upon drying. The inter-annual variation soil respiration at the Harvard Forest, 0.23 kg C m-2 yr-1, exceeds the inter-annual variation in net ecosystem exchange (NEE), 0.14 kg C m-2 yr-1 previously measured for this forest, indicating that inter-annual variation in soil respiration can have an important influence on NEE.
