Figure 4From: Effects of shortened host life span on the evolution of parasite life history and virulence in a microbial host-parasite systemFinal host density in the individual assay. Densities measured 20 days after isolation of single individuals. Means for parasites from early- and late-killing treatments were based on selection line means; means for uninfected controls were taken across all assay tubes.
