Mean effect sizes comparing the change in genetic variation across environments for studies where novel environmental manipulations were stressful (Stressful/Nonstressful) and with different breeding designs (Half-sib vs. Full-sib). (A) Total SDV between G matrices across environments. (B) Change in the proportion of variation along ${\mathit{g}}_{max}$ (PV_max) between G matrices across environments. Note that in all cases effect sizes are means for a study for an average number of traits and are independent of other factors (i.e., marginalized means) in the model (see Materials and Methods).
