Temperature–dependence of metabolic (A,B) and consumption rates (C,D). (A,B) The relationship between temperature and metabolic rate in Oregon R (A), and Canton S flies (B). The metabolic rate was measured in males that developed and were kept at 25 °C (12:12 L:D; 60–70% humidity) for four days and were prior to metabolic rate measurements exposed to given temperature for two days to allow acclimation. The values represent mean O₂ consumption per fly per hour measured during two-hour period (10:00–12:00 AM). (C,D) The relationship between temperature and consumption rate in Oregon R (C), and Canton S flies (D). The values represent mean daily food intake of individual males measured over a four day period. For global statistical analyses see Supplementary Table S3. Lines represent linear regressions. Each data point represents the mean value ± s.e.m. Sample size is reported in parenthesis.
