Table 8 Estimates for the fixed and random effects of the mixed-effects models of reproduction as a function of growth (reproduction and growth). Pearson’s R correlation between the observed and predicted data using independent training and validation datasets; marginal variance explained by the fixed effects (R²M) and by the fixed and random effects together (R²C). Results are obtained after 100 bootstraps
