Our research focuses on the development of African savannas in the Plio-Pleistocene. As a tool we work among other things with the analysis of stable isotopes from pedogenic archives to reconstruct the development of C4-grasslands as a result of changing atmospheric CO2-concentration, seasonality and distribution of precipitation, and retreat of tree cover. The southeast African savanna is here particularly interesting since the vegetation pattern can be correlated with paleontological data of the evolution and migration of the early hominids.
