报告内容简介:
        The ongoing global change exerts significant impacts on vegetation dynamics, ecosystem stability, and carbon cycling. In this talk, I will discuss (1) critical transitions from grassland to woodland driven by climate warming and microclimate feedbacks in Northern American woodland-grassland ecotones; and (2) the fundamental role of vegetation productivity and rainfall dynamics in controlling the variability of soil heterotrophic respiration across ecosystems. The results provide theoretical and empirical evidence of the emergence of ecosystem regime shifts and stochastic behavior of ecosystem carbon fluxes, which will improve our projection of ecosystem stability and carbon balance under future global change.
