  1. A0 is the initial mortality rate, which is age-independent. G is the Gompertz coefficient, which expresses the exponential increase in age-specific mortality rate. MRDT is the mortality rate doubling time, which is expressed in years to facilitate comparison with other species. 95% CI is the 95% confidence interval of the parameter as obtained by WinModest. For every parameter, the average and standard deviation (SD) of the three replicate cohorts are calculated and presented.
