Terrestrial-like (A) and river-like landscapes (B) lead to differences in virulence evolution (C) which vanish when parasite kin structure is broken (D). Thus, differences in virulence evolution between the two landscape types is explained by diverging patterns of landscape defined parasite relatedn
