Sex-Specific Life History Dynamics in Drosophila Under Selection

743,501 bytes of data from an experiment on Drosophila melanogaster populations selected for faster development and increased longevity (FLJs) compared to ancestral controls (JBs). The study reveals a sex-specific divergence in resource allocation, where FLJ males achieved higher longevity with comparable reproductive effectiveness, while FLJ females showed reduced lifetime fecundity and ovariole numbers. These findings illustrate trade-offs between growth, reproduction, and somatic maintenance under simultaneous multi-trait selection.

Use Cases

• Testing predictions of the Disposable Soma Theory based on longevity and fecundity measurements.
• Analyzing sex-specific evolutionary responses using data on pre-adult development and adult longevity.
• Investigating resource allocation trade-offs between reproduction and somatic maintenance.
• Comparing life history trait evolution in selected (FLJ) versus control (JB) Drosophila populations.

Strengths

• Dataset is openly licensed under CC-BY-4.0, facilitating reuse and sharing.
• Data originates from a controlled experimental evolution study, providing a clear comparative framework.
• Cross-platform presence on figshare indicates established sharing and potential for visibility.

Limitations

• Column names and a precise row count are not provided, limiting understanding of the data structure.
• The dataset size is given only in bytes (743,501), which is not a standard measure of data volume for users.
• Organization information for the author is missing, which can affect provenance assessment.
