Novel Theoretical Approaches for Global Biogeochemical Cycles

In this project we will take a systems theoretical view on global biogeochemical cycles and develop novel computational method in order to tackle their enormous complexity. The project might combine a systems analysis methodology developed by the Bio Systems Analysis Group - like network analysis or multi-agent modeling -with a particular application in the domain of global biogeochemical cycles. An example is multi-scale modeling combined with the automatic identification of hierarchical structures in atmosphere chemistries (cf. F. Centler, P. Dittrich, Planet. Space Sci. , 55(4): 413-428, 2007; with its theoretical background in P. Dittrich, P. Speroni di F., Bull. Math. Biol., 69(4):1199-1231, 2007). The basic idea is to decompose the complex reaction network of atmospheric chemistry into an overlapping hierarchy of algebraically closed and self-maintaining sub-networks. Then the spatial dynamics of the system can be mapped to this decomposition and explained in a fundamentally new way. Another possible direction of research we will explore - in collaboration with the Biospheric Theory and Modelling Group lead by Axel Kleidon at the MPI for Biogeochemistry - the application of multi-agent simulation to study the interaction between the earth climate system and the biological system, e.g., the vegetation system in particular (e.g., K. Bohn et al. Biogeosciences Discuss., 7, 8215-8243, 2010). The individual based approach might also encompass evolutionary dynamics.
