Table 1. Effects of interactions between the variables Early treatment, Family lineage, and Sex on body mass at completion of the early experiment.

Results derive from a linear mixed model including the variable Start date (the time of allocating hatchlings to individual treatments) as a random effect to account for a potential influence of photoperiod on development. Body mass was log-transformed. Significant P values are shown in bold.
