Fig 2. The influence of senescent mortality, mediated by age-independent mortality, on the relationship between ${\overline{l}}_0$ and e₀ (in years).

Shown are data points calculated from mortality trajectories where b₀ and b₁ > 0, c ≥ 0, and b₀ = b₁ = 0. (a) The effect of the level of senescent mortality (b₀). (b) The effect of the rate of senescent mortality (b₁). (c) The effect of age-independent mortality c.
