We obtained lizard eggs from high- (fire ant invaded) and low-stress populations. Offspring were exposed weekly to fire ants or corticosterone until maturity. Early life stress did not affect stress physiology in adulthood. Transgenerational history with stress increased adult CORT reactivity. Stress exposure across generations may be more important than within a lifetime.
