Contrasting Patterns Of Phenotype-Dependent Parasitism Within And Among Populations Of Threespine Stickleback
Variation in infection rate arises from variation in host exposure and resistance to parasites both within and among populations. All things being equal, phenotypes that increase exposure risk should covary positively with infection among individuals. It might therefore be expected that populations...
