Abstract

The metabolic rates of wild-caught adult female Drosophila melanogaster measured at 22@*C are significantly greater than those of sympatric Drosophila simulans. Similarly, the temperature-specific metabolic rates, measured at 18, 22, and 25@*C, in laboratory-reared granddaughters of the wild-caught D. melanogaster are greater than those of the laboratory-reared granddaughters of the wild-caught D. simulans females. These genetically encoded differences in metabolic rate between the two species may be related to differences in fecundity and seasonality.
