Abstract: Changing places These T4 page and their E. coli hosts are the model for a typical 'victim-exploiter' interaction in a study of the role of migration patterns in a 'tragedy of the commons' competition for limited resources within fragmented communities. In this host-pathogen system, growing in 96-well microtitre plates, coexistence, stability and evolution within the separated communities depend critically on migration: restricted migration can promote restraint in the use of the common resource. In this experiment and in theory, highly connected social networks favour virulence.
