Drosophila Pseudoobscura Aging 2026: Lifespan, Development Time, and Body Size Data

Data and analysis code for lifespan, development time, and body size assays in the fruit fly Drosophila pseudoobscura. The repository consists of nine data files and four code scripts, with data collected across different strains and temperatures. It was authored by Richard Meisel and last updated in April 2026.

Use Cases

• Modeling lifespan and mortality curves based on strain and temperature variables.
• Analyzing development time from egg to adult based on temperature and strain data.
• Investigating correlations between body size, development time, and lifespan.
• Comparing aging phenotypes across different third chromosome arrangements.

Strengths

• Includes data from assays conducted at three different temperatures (18C, 22C, 25C).
• Repository contains nine data files and four accompanying R analysis scripts.
• Data covers multiple phenotypic traits: lifespan, development time, and body size.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal or laboratory bias inherent to the experimental setup.
