Fig. 1. The time course of change in plasma corticosterone levels of 40 female
water skinks (Eulamprus heatwolei) following exposure to a stressful
stimulus (having a blood sample taken, then being chased around an enclosure
for 30 s), and 10 `control' females that were undisturbed prior to the blood
sample being obtained. Each sample is based on data from 10 females, so that
each animal provided only a single sample for analysis. Values are means
± s.e.m.
