Note: F ratios are from separate nested ANOVA of the parameters from a logistic mortality model. Treatment is the environment in which the populations were evolved and environment indicates the conditions under which longevity was assayed. α is the initial mortality rate, β estimates the rate of senescence, and s is the rate of mortality deceleration. Results of post-hoc tests of significant effects (bold) are given (m = males, f = females, 5 = hypoxia, 21 = normoxia, 40 = hyperoxia).
