FIG. 2. Effect of manipulating paternal density on offspring post-metamorphic survival across low- and high-density offspring environments. Offspring sired from high-density males are shown in black; offspring sired by low-density males are shown in gray. (a) Absolute survival. Points are mean survival proportions for each set of six replicates per treatment combination per trial. Low offspring density values have been jittered slightly so that each point can be seen clearly. High offspring density values are mean densities for each set of six replicates. (b) Relative survival. Points are relative survival, calculated by dividing each point by the average survival within each environment.
