  1. Summary test statistics for a linear mixed model with ln(yolk sac area) as response variable. Replicate is random effect. Adjusted R2 = 0.713, N = 713. The parameter estimates are available in table A1 in Additional file 1. Square brackets indicate the nesting structure. Layout details: The (ln°d)2 notation indicates the total polynomial effect (i.e., ln°d + (ln°d)2) was fitted as a orthogonal polynome, an asterisk between model terms indicates interaction effect, and Df indicates degrees of freedom for the relevant model term.
