The general outcomes of long-term trajectories of coevolutionary interactions between specific hosts and pathogens are set by the interaction of their life histories. However, within those outcomes the speed of co-evolutionary responses and the extent of their expression in the resistance/virulence structure of wild plant and pathogen populations respectively, are highly variable characters changing from place-to-place and time-to-time as a result of the interaction of host and pathogen with the physical environment. As a consequence, understanding of the role of diseases in the evolution of their hosts requires approaches that simultaneously deal with host and pathogen structures over multiple populations within a metapopulation framework.
