Session ID#: 15614

Session Description:
Climate extremes, such as drought and heat waves, are increasing in frequency and intensity, and the economic and ecological consequences of these extreme events can be substantial and widespread. Although there is still much to be learned about how ecosystems will respond to an intensification of climate extremes, even less is known about the factors that determine recovery of ecosystem function after these events. Such knowledge is particularly important because recovery periods can be protracted depending on the extent to which key plant populations, community structure and biogeochemical processes are affected. This session will address our current understanding of what factors determine the nature and pace of terrestrial ecosystem recovery after climate extremes. We invite contributions from biogeochemists, ecologists, hydrologists, and system modelers with expertise in the study of terrestrial ecosystem recovery from climate extremes.
