Data from: Shoaling guppies evade predation but have deadlier parasites

We collected data on coinfection rates, infection prevalence, and
infection intensity for Gyrodactylus spp. on wild Trinidadian guppies
(Poecilia reticulata). We also collected data on the shoaling preference
of wild-caught guppy hosts. Further, we collected data on transmission
rates, infection intensity, and infected host mortality rates of lines of
these parasites on guppies in the laboratory. We fouind that wild guppy
populations with stronger shoaling preferences had higher infection
prevalence and coinfection rates. Further, we found a transmission
rate-virulence tradeoff among parasite lines mediated by infection
intensity. Lastly, parasite lines from populations with stronger shoaling
preferences were found to attain higher infection intensity and impose
higher mortality on infected hosts. These data may be re-used with
citation of the corresponding manuscript, "Shoaling guppies evade
predation but have deadlier parasites." For more information, see
