Fig 1.

A factorial study design.

Eggs collected from an outbred population reared on maintenance diet (M) were seeded on H and L diets for development. Emerged flies from each treatment were split to H and L diets as adults in two large cage replicates for each treatment (NCAGES = 8). From each cage we measured fecundity and lifespan.

Fig 2.

Probability of survival grouped by larval-adult diet regime and sex.

Broken lines depict age (days) at median survival probability. Survival responded in an age-specific manner to treatment combinations, and differently between the sexes.

Fig 3.

Pattern of egg output in each treatment of larval-adult diet regime. a-c: Mean age-specific fecundity (i.e., mean number of eggs laid in a 3-hour period in each diet regime over lifespan is plotted.

Lines are linear models of those diets; d-f: same data in a-c calculated per female; c,f: are estimated regime effects calculated from regressing numbers of eggs on regime, ether in group fecundity c or per female fecundity f.

Fig 4.

Effect of regime on lifetime fecundity in D. melanogaster. Hedge’s d statistic for pairwise regime comparisons.

Positive effects reflect a larger effect (mean) of the first diet sequence before ‘vs’ while negative effects reflect a larger effect of the second sequence. We interpret these results as d < 0.2 (small effect), 0.2 ≤ d < 0.5 (medium effect), 0.5 ≤ d < 0.8 (large effect), and d ≥ 0.8 (very large effect) (Hedges and Olkin, 1985).

Fig 5.

Average number of eggs per female per day calculated from 3-hour laying periods sampled 3 times a week over lifetime. a – grouped by larval treatment H or L. b – grouped by adult treatment H or L. c – Mean difference in egg number per 3-hour laying period in each regime. d – Number of detected change points in egg-laying and duration of these periods.

Fig 6.

Age-specific fecundity patterns in each of the four diet combinations.

A reproductive value is the expected per 3-hour fecundity of a female calculated from lifespan-fecundity Leslie matrices. The dots represent mean per female fecundity at each sampling time over the lifespan.
