Drosophila Thermal Adaptation Data on Life History and Stress Traits

20 generations of laboratory selection on Drosophila simulans populations under constant, predictable, and unpredictable daily fluctuating thermal regimes. The data explores genetic and environmental correlations between traits like productivity, body size, starvation, and desiccation tolerance. It was created by Tommaso Manenti and published in 2020.

Use Cases

• Analyze genetic correlation matrices between productivity and body size across different thermal selection regimes.
• Model the effect of test regime on correlations between starvation tolerance and productivity using the experimental population data.
• Compare evolutionary responses in desiccation tolerance between populations selected in predictable versus unpredictable thermal environments.
• Investigate how environmentally dependent gene activation influences trait correlations in the three defined thermal test regimes.

Strengths

• Data originates from a controlled 20-generation laboratory selection experiment, providing clear evolutionary time series.
• Explicitly tests three distinct thermal regimes (constant, predictable fluctuating, unpredictable fluctuating) for both selection and testing.
• Focuses on correlations between multiple ecologically relevant traits: productivity, body size, starvation, and desiccation tolerance.

Limitations

• The specific data format, row count, column names, and individual measurements are not provided in the input.
• Findings are specific to Drosophila simulans in a laboratory setting, limiting direct extrapolation to wild populations or other species.
• The dataset's size and granularity are unknown, which may constrain certain types of multivariate or time-series analyses.
