Data from: Dynamic transmission, host quality and population structure in a multi-host parasite of bumble bees

The evolutionary ecology of multi-host parasites is predicted to depend upon patterns of host quality and the dynamics of transmission networks. Depending upon the differences in host quality and transmission asymmetries, as well as the balance between intra- and inter-specific transmission, the evolution of specialist or generalist strategies is predicted. Using a trypanosome parasite of bumble bees we ask how host quality and transmission networks relate to parasite population structure across host species, and thus the potential for the evolution of specialist strains adapted to different host species. Host species differed in quality, with parasite growth varying across host species. Hi…
