Résumé

Global climate change is predicted to increase the intensity and frequency of futuredrought, which in turn may be expected to induce a range of biogeochemical climatefeedbacks. Acombination of model simulations and observational studies of a recentwide-scale drought, suggested that the drought induced substantial terrestrial ecosystemcarbon loss, but hypothesized mechanisms could not be evaluated via comparison toa control. Here, we investigated carbon-cycle responses to climate changes bycombining results from a controlled 15-year ecosystem warming experiment inmontane grassland with observational data from before and during the recentdrought. We found that both experimental warming and real-world drought inducedsubstantial soil carbon loss in our study system, and that the same mechanism, adrying-induced shift in plant species composition and an associated decline in communityproductivity, provides a common explanation for these declines in soil carbon.
