Boxplots (description see Fig 1) of concentrations of glucocorticoid metabolites (GCM; ng/g droppings) of female Blue-fronted parrots (<i>Amazona aestiva</i>), kept under natural light variation (sunrise: 06:02 ± 0:11 a.m.—sunset: 06:09 ± 0:03 p.m.–mean ± standard deviation), after an injection of saline solution (0.9% NaCl; white boxes), dexamethasone (1 mg/Kg; white striped boxes) and adrenocorticotropic hormone (25 IU of ACTH; gray striped boxes).

Please note the different y-axis scale in the upper (Dexamethasone; ACTH) and lower (Saline; Control) panels. Asterisks beside the gray striped boxes indicate significant differences compared with the same interval of the control group (<i>P</i> < 0.01). The P values of time (T), treatments (Treat) and the interaction time*treatments (T*Treat) are shown.</p> 2016-01-05 14:53:54 saline 25 IU IM hormone aestiva blood corticosterone concentrations acth behavioural disorders experiment method gcm blood sampling techniques adrenocortical activity dropping parrots Amazona eia species cortisone enzyme immunoassay stress measure glucocorticoid metabolites validation
