Effect of DR of yeast with constant sugar on male and female mortality rates in Drosophila. (A and B) Comparison of 1.0X media to 0.4X media. Left panel, raw survival data. Center panel, plot of natural log mortality rate versus time, and trend line for data fitted to the G-M model. Right panel, reconstructed survival curves for data fitted to the Gompertz model. (A) Female Drosophila. (B) Male Drosophila. Statistical summary in Table 1. (C and D) Change in parameter a versus change in parameter b across four yeast concentrations: 0.4X, 0.6X, 1.0X, and 3.0X. (C) Female Drosophila. Linear regression R[2] = 0.99, significance of predictor p = 0.00474. (D) Male Drosophila. Linear regression R[2] = 0.75, significance of predictor p = 0.134.
