Fig. 3. Daily egg-to-adult viability (proportion of eggs laid that emerged) for flies experiencing constant (A) and transient (B) temperatures. In B, egg-to-adult viability is shown as the difference between treatment viability and viability at constant 25°C on the same day. Flies were kept at 25°C except for 1 day at 18°C or 29°C and 3 days at 18°C. P values from Kruskal–Wallis rank sum tests for each day are shown below each plot; values in bold are significant at P=0.05 level.
