Experiment 3 results (one or two exposures, three temperatures, but only one host genotype, see text). Panel A presents the average number of offspring produced per Daphnia until degree-day 700 at 15°C, 20°C, and 25°C. Panel B presents the proportion of hosts alive until degree-day1200 at 15°C, 20°C, and 25°. For panels A and B, full black lines represent hosts that were not exposed to parasites, dashed lines and dotted lines those that were exposed to a single or a double dose (respectively) but did not develop infection. Bars are standard errors.
