Abstract: Antagonistic interactions like those between hosts and parasites or parasitoids or between predators and prey are important for many ecological and evolutionary processes. Here, we contrast the effect of commensalism and host-parasitoid interaction (complete fertility loss for infected host), on the concurrent evolution of host dispersal and habitat niche width. We assume that host habitat niche width is associated with a fertility trade-off; the wider the habitat niche, the lower the maximum fertility in optimal habitats. We implement a spatially explicit, individual-based one-host-one-guest metacommunity model (guest species are commensals or parasitoids) with landscape heterogeneity of a continuous habitat trait that affects the host's fertility only. The antagonistic interaction model follows the Nicholson–Bailey equation.
