Paraquat resistance and starvation conditions in the selection of longevity extremes in Drosophila melanogaster populations previously selected for long and short developmental period.

This paper analyzes the interaction between resistance to free radicals, development under starvation conditions, sex, and its consequences to the lifespan of Drosophila melanogaster populations selected for developmental time and longevity. Our data suggest that the interaction between these physiological and environmental parameters is modulated largely by the pre-imaginal developmental time, since the response to selection for longevity extremes depends strongly on the previous selection for developmental time extremes.
