Figure 1.

Effect of breeding treatment and four ecological and demographic factors (covariates) on the size of A. cf. jucundus inbred/outbred offspring at three stages of their life cycle. Leftmost panels show mean±95% CI, estimated across individual family means. Dots in the top two rows represent individual family means (inbred clutches, grey; outbred clutches, black); dots in the bottom two rows are means for male (third row) or female (bottom row) offspring in a family. Separate regression lines for inbred/outbred offspring shown only where there was a significant difference between treatments. None of the interactions between treatment and covariates were significant. See table 1 for significance tests and table 2 for the proportion of the variance accounted for by each of the factors at the end of the maternal and social phases.
