Table 4. Effects of interactions between Treatment, Family lineage, and Sex on total duration of development and adult size.

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