Abortions
There was evidence of variation between individual mothers in the
probability of abortion for the nutritional stress group (model with
random intercept ω = 0.985; model without ω = 0.015), but
not for the control or mating delay groups, based on comparison of
models with and without random effects (Table S4.5). The predicted
probability of abortion increased with age across all treatments, up to
c. 0.2 for the mating delay group and c. 0.5 for the control group by
100 days (Fig. 3, Table S4.5). Females in the nutritional stress group
had higher expected probability of abortion than those in the control or
mating delay groups for any given age, increasing to c. 0.7 by 100 days
(Fig. 3, Table S4.6).
