Abstract
We consider an individual-based spatial model of a generic host-pathogen systemand explore the differences between such models and mean-field systems. Wefind a range of new dynamical and evolutionary phenomena. In particular, (i) inthis system selective pressure is substantially reduced compared to the correspondingmean-field models and artificial suppression of the pathogen population leadsto faster evolution and reduces evolutionary stability; (ii) unlike the mean-fieldmodels,...Keywords
