Initial responses of carbon cycling to elevated CO2 and warming in native semiarid grassland,Wyoming,USA

摘要：

Introduction The effect of climate change on carbon (C) cycling,and potential feedbacks to global warming,constitute major uncertainties in prediction of future ecosystem sustainability.Decomposition of soil organic matter ( SOM ) pools may be stimulated by warming,but additional allocation of C belowground due to elevated atmospheric CO2 may offset warming-enhanced losses.
