Project C2

Vegetation dynamics in the Palaeogene and Late Cretaceous: feedback on climate and habitats for mammals

Julia Brugger

Principal Investigators: Thomas Hickler, Susanne Fritz (Senckenberg), Bodo Ahrens, Silke Voigt (Goethe University Frankfurt)

In this project, the role of dynamic vegetation changes in the climate system should be explored with a coupled vegetation-climate model, in particular to advance our understanding of polar amplification. Simulated climate gradients and vegetation shifts will be evaluated against the results from other VeWA projects and existing data. The vegetation-climate modelling will be carried out in collaboration with C1, most likely with the Community Earth System Model (CESM). In addition, a more detailed dynamic global vegetation model (LPJ-GUESS) should be used to simulate climate-driven changes in vegetation composition and structure to investigate habitat changes for mammals and other organism groups at the World Heritage site „Grube Messel“ and in North America (with projects B1-B3). B-projects will also provide forcing data derived from geological proxies. The vegetation modelling will be facilitated by other members of the LPJ-GUESS development group.
