Effects of age at maturity, r, on the genetic drift per time step, σdg2, the ratio of effective population size to census (total) population size, Ne/N, and the proportion of adults at stable stage structure, uad, in populations with different levels of juvenile survival. Annual survival probability of prereproductive individuals, sym = syf, is equal to 0.5 (solid lines) and 1 (dashed lines). In the middle panel, the dotted line shows the ratio Ne/Nad, where Nad is the adult population size (as opposed to the total population size used in the ratio Ne/N represented by the solid and dashed lines). Variance in annual male mating success is equal to 2, the sex ratio, q, is equal to 0.5, and the expected number of offspring is adjusted to maintain a growth rate, λ, of 1.
