The occurrence of multiple pathogen species on a shared host is unexpected when they exploit the same micro-niche within the host. One explanation for such observations is the evolution of pathogen-specific resistances that segregate the host population into sites that are differentially occupied by the competing pathogens. This study used experimental inoculations to test whether specific resistances may contribute to the maintenance of two anther-smut fungi in natural populations of Silene uniflora in England and Wales.
