Résumé
Spatial patterns of parasitism are thought to be strongly associated with local adaptation, relative rates of migration by hosts and parasites, and local levels of resource availability. This chapter reviews theoretical and empirical studies of local adaptation, and their bearings on spatial patterns of parasitism. It then reviews theoretical and empirical studies of dispersal and parasitism, and theoretical and empirical studies of the relationship between productivity and spatial patterns of levels of parasite defence and host offence. The effects of these processes on the distribution and spatial patterns of coexistence of hosts and parasites are investigated.
