Treatment effects on logistic (male) and Gompertz (female) mortality parameters when measured under severe desiccation stress at generation 15(10 hyperoxia).

Note: Results of nested ANOVA, separately by sex, testing for treatment differences (d.f. = 2,9 in all cases). α is the baseline mortality rate, β is the rate of senescence, and s is the rate of mortality deceleration (estimated in males only).
