Quantitative characterization (mean ± SEM) of the adrenocortical response of 15 greater sage grouse to capture, chemical injection (ACTH or saline), and up to 22:43 h of confinement

		Injection		Sex
	All Birds	ACTH	Saline	Male	Female
n	15	7	8	8	7
1° slope (ICM/min)^a	4.25 ± 1.19	3.02 ± 1.74	5.31 ± 1.63	5.17 ± 1.64	3.19 ± 1.76
1° peak (1° peak ICM/baseline ICM)	4.27 ± .72	3.74 ± 1.07	4.73 ± 1.00	5.04 ± .97	3.39 ± 1.04
Time to 1° peak (hours:minutes)	2:05 ± 0:08	2:14 ± 0:12	1:59 ± 0:10	2:17 ± 0:09^b	1:51 ± 0:11^b
2° slope (ICM/min)	.73 ± .16	1.18 ± .27^c	.38 ± .13^c	.96 ± .21	.18 ± .16
2° peak (2° peak ICM/baseline ICM)^d	3.85 ± .92	5.24 ± 1.29	2.63 ± 1.21	5.11 ± 1.20	2.41 ± 1.28

Note. Boldface type indicates statistical significance at P < 0.05.

Units for ICM are ng ICM/g dry feces.

Sex-wise comparison of time to peak response postcapture by t-test (P = 0.0994) and one-way Wilcoxon test (P = 0.0525).

Injection-related difference in 2° response slope (mixed-effects ANCOVA, P = 0.0139 for effect “HPI × injection type”).

No statistical analyses to compare group means were performed for this category because of an inconsistent total time of captivity among birds.
