Estimating changes in terrestrial vegetation and carbon storage: Using palaeoecological data and models
International audience Climatic changes that accompanied the transition from the last glacial to the present interglacial conditions over the past 18,000 (14)C years impacted both terrestrial ecosystem structure (vegetation distribution) and function (carbon dynamics), which in turn influenced the c...

International audience Climatic changes that accompanied the transition from the last glacial to the present interglacial conditions over the past 18,000 (14)C years impacted both terrestrial ecosystem structure (vegetation distribution) and function (carbon dynamics), which in turn influenced the climate through biogeophysical mechanisms. Palaeoecological records provide not only past records of vegetation patterns at various spatial and temporal scales, but also a means of evaluating the associated change in past terrestrial carbon storage. After a brief review of the role of palaeoecological data and biosphere models in evaluating the potential impacts of past climate change on terrestrial ecosystems, we synthesize the methods for reconstructing the vegetation patterns from palaeoecological data and the way to integrate it with biosphere models to reconstruct the long-term terrestrial carbon dynamics since the Last Glacial Maximum (LGM). The main results obtained at both the global and regional scales suggest that colder, more arid and low atmospheric CO(2) climatic conditions at the LGM may have favored the extensions of steppe and grassland dominated by C4 plants, to the detriment of forested ecosystems.
