- Body weight (g), kidney somatic index (KSI, kidney weight/body weight × 100), gonad somatic index (GSI, gonad weight/body weight × 100) and plasma levels (ng/ml) of 11-ketotestosterone (11KT) and testosterone (T) in breeding and post-breeding male and female sticklebacks. Means ± S.E. are shown. n = 6. a (Tukey's post hoc test, < 0.001) compared to all other groups. b (ANCOVA, p < 0.05) compared to post-breeding males. c (ANCOVA, p < 0.001) compared to post-breeding females. d (Tukey's post-hoc test, p < 0.05) compared to post-breeding males and females.
