Lifespan and fecundity of wild–derived <i>Drosophila melanogaster</i> strains responded to DR.

<p>The mean lifespans of all wild-derived strains and the laboratory strain exhibited a tent-shaped response to DR with highest mean lifespan values at 0.5 or 1.0 yeast concentration. Female fecundity showed a monotonic increase with yeast concentration in all strains. Both mean lifespan and fecundity were significantly affected by food. Mean lifespan for <i>W^Dah</i>: F = 94.21, R² = 0.8933, <i>p</i><1×10⁻⁴, for <i>FRA</i>: F = 35.42, R² = 0.7589, <i>p</i><1×10⁻⁴, for <i>GRE</i>: F = 81.23, R² = 0.8784, <i>p</i><1×10⁻⁴, for <i>GER</i>: F = 96.66, R² = 0.8957, <i>p</i><1×10⁻⁴, for <i>NETH</i>: F = 43.25, R² = 0.7936, <i>p</i><1×10⁻⁴, one-way ANOVA test. Fecundity for <i>W^Dah</i>: F = 136.5, R² = 0.9239, <i>p</i><1×10⁻⁴, for <i>FRA</i>: F = 158.3, R² = 0.9337, <i>p</i><1×10⁻⁴, for <i>GRE</i>: F = 103.1, R² = 0.9016, <i>p</i><1×10⁻⁴, for <i>GER</i>: F = 107.6, R² = 0.9054, <i>p</i><1×10⁻⁴, for <i>NETH</i>: F = 123.5, R² = 0.9165, <i>p</i><1×10⁻⁴, one-way ANOVA test. Points: mean lifespan. Bars: estimate of mean number of eggs laid/fly/day ± standard error; connected points: mean lifespan in days (<i>n</i> = 100). Data shown are from a single trial with second generation flies of the wild-derived strains.
