Plasticity of liver mRNA levels for 14 genes in 72 half-sib Chinook salmon families at two temporal scales: (1) rearing environment (semi-natural and hatchery) and (2) stress response to an acute confinement stress for 24 h (rest and stress). Points (mean ± 2 SE) represent the estimated coefficient from the linear model and the statistical significance of main effects (RE rearing environment, SR stress response) and interactions (X) are indicated in each plot as determined using a linear mixed effects model with approximate F-tests using the Kenward–Rogers approach to estimate degrees of freedom
