Conceptual model of ecological and evolutionary relationships within communities that regulate prevalence of infection with a zoonotic pathogen in the reservoir host. (A) A simplified metacommunity composed of five communities (A, B, C, D, E). Reservoirs (red) and related species (alternative host species in orange) maintain higher infection prevalence. The highest prevalence is expected in communities C, D, and E and the lowest in communities A and B with nonhost species in blue. (B) Phylogenetic tree of all species in the metacommunity.
