Figures
- Fig. 1.
(A) Resting metabolic rate (RMR) of adult butterflies measured at 26°C and at 32°C. The horizontal axis gives the wet adult body mass. Pgi genotype had no effect on RMR. (B) Peak flight metabolic rate (MRpeak) plotted against wet body mass. Grey squares and the dashed line represent Pgi AA111 AA homozygotes, black dots and the solid line Pgi AA111 AC heterozygotes. The temperature treatment had no significant effect.

Effects of adult body mass, measurement temperature, time of measurement and Pgi genotype on pupal metabolic rate (A–C), adult resting metabolic rate (D–F) and peak flight metabolic rate (G-I). (A,D,G) The rate of CO2 emission plotted against body mass. (B,E,H) Residual mass-independent metabolic rates plotted against measurement temperature. B and H show interactions between Pgi genotype and temperature. Grey squares and the long dashed line represent the genotype AA, black circles and the solid line represent AC, and white triangles and the short dashed line represent the CC genotype. (C,F,I) The effect of the time of day on residual metabolic rates (adjusted for mass, temperature and, when significant, for the genotype by temperature interaction).
- Fig. 3.
Peak flight metabolic rate (adjusted for body mass) plotted against measurement temperature in a pooled dataset containing the Finnish individuals from the two experiments. Grey squares and the dashed lines represent AA111 AA homozygotes, and black dots with the solid lines represent the AC heterozygotes. The long regression lines were fitted to the full dataset, while the short regression lines were fitted only to the data for higher temperatures and show an interaction between genotype and temperature (F1,69=10.31, P=0.002).
