AGE CLASS
Fig. 15.12
Age-specifi c percentage mortality rates per round of mating in comparative trials
modeling the founding and subsequent growth of populations of a dioecious shrub similar
to
Lindera benzoin
(exact specifi cations are given in
Table 15.2)
.
Recall that trial q has the exact same age-specifi c mortality input
conditions as trial m, regardless of the age at which the 172 founders are
planted. In Fig. 15.12, trial q would appear exactly like trial m (but is not
shown for visual clarity). As outlined in Table 15.2, trials q and m are similar
to trial r in mortality schedules except for early slightly reduced rates of
mortality for population r. At age class 10, trials m, q, and r all have equal
and unchanging, low midlife mortality rates followed by a steep and equal
