Female adult metabolic rate is robust to mito‐nuclear genetic effects. (A) The only mito‐nuclear genetic effect was a small, but significant decrease in 16°C routine metabolic rate (RMR) in incompatible (simw ⁵⁰¹);OreR females (P < 0.05, Table S5). (B) At each measurement temperature, mass‐corrected metabolic rates were similar for females developed at different temperatures, indicating strong physiological homeostasis for metabolic rate. (C and D) Thermal reaction norms show that the Q ₁₀ for female mass‐corrected metabolic rate is similar under both developmental temperatures, and that incompatible (simw ⁵⁰¹);OreR females have similar metabolic plasticity as their nuclear genotypic control (ore);OreR. The analogous data for adult males are provided in Figure S2 and revealed similar patterns as observed in females. The mtDNA × nuclear interaction did not affect mass‐corrected metabolic rate of males or females at either measurement temperature (P > 0.28; Table S6). Error bars are ±1 SEM and symbols and colors designate genotypes as indicated in panel A.
