摘要
We integrated two methods, experimental heating and observations across natural 氣候 gradients, to elucidate both short-and long-term climatic controls on ecosystem carbon storage and to investigate carbon-cycle feedbacks to 氣候 in montane meadows. A 10-year heating experiment warmed and dried heated plot soils and substantially decreased (by similar to200 +/- 150 g C m(-2)) the amount of carbon stored in soil organic matter, a positive feedback to warming. In situ CO2 flux measurements, laboratory soil incubations, and a heating-induced shift in vegetation community composition from high- to low-productivity 物種 indicate that a decline in community productivity and resultant decrease in soil inputs from plant litter caused most of the soil carbon decrease. An alternative widely hypothesized m
