Relocation produced an overall increase in serum cortisol concentrations in monkeys, an effect that was maintained through the 1-year sample period (left Y-axis, dotted line, mean ± SEM; *p < 0.001 for pre-move compared to post-move, and *p < 0.01 for pre-move compared to 1 year later). Serum CBG concentrations at the post-move sample period showed no variation from the pre-move samples (right Y-axis, solid line, mean ± SEM; p = 0.91), but a significant increase occurred between the post-move and 1 year sample periods (*p < 0.005). No significant differences were found for serum cortisol or CBG between SIB and control monkeys at any of the three time points (not shown).
