Dynamics and Evolution of Networks: From the Genome to Ecosystems — •Barbara Drossel — Institut für Festkörperphysik, TU Darmstadt, Hochschulstr. 6, 64289 Darmstadt

This talk presents an overview of my research projects in the field of genetic networks and foodwebs. The study of genetic network models begins with Kauffman networks and aims at understanding the relation between the structural network properties and the properties of its attractors. The long-term goal is to model network evolution by including biologically realistic features such as mutator genes, transpositions and duplications. The main question addressed in the study of foodweb models is the relation between the population dynamics and the structural properties of foodwebs under long-term evolution. Our recent research shows that only certain types of population dynamics allow the formation and long-term persistence of complex webs.
