a Average fecundity per female on day 11 (post-eclosion), b dry-weight per female at pre- and post-fecundity stages, and c fecundity per unit dry-weight loss (difference in pre- and post-fecundity dry-weight) for the early (E), the early-control (EC), the control (C), the late-control (LC) and the late (L) populations in LD12:12. Error bars indicate 95 % confidence intervals calculated by method of Tukey’s HSD. d Pearson correlation of average fecundity/female with that of dry-weight lost during the fecundity assay (r = +0.75, p < 0.0001). The data points for correlation were obtained by pooling values across all 20 populations. The dotted line indicates 95 % confidence interval. Fecundity and dry-weight measurements assays were performed only in LD12:12. Bars sharing same letters do not differ statistically while those with different letters are significantly different from each other
