This study shows that genetic variation persists under intense directional selection in Drosophila and can be rapidly redeployed when selection reverses, suggesting balancing-selection maintains this variation.

The paper examines microbiota changes in Drosophila melanogaster populations selected for different aging trajectories, finding a consistent loss of Wolbachia in short-lived populations and its dominance in long-lived ones.

This study uses metabolomic profiling in Drosophila melanogaster to show that selection for early reproduction leads to repeatable metabolic changes and a reliable predictor of biological age.

This study investigates the genetic basis of Drosophila melanogaster's defense against Beauveria bassiana using QTL mapping and evolve and resequence approaches, revealing genetic variation and trade-offs in immune defense.
