Table 4 Comparison of CORT concentrations of Canary Islands stonechats with those of African and European stonechats

From: Baseline and stress-induced levels of corticosterone in male and female Afrotropical and European temperate stonechats during breeding

  Africa Canary Islands Europe
Males ng/ml ng/ml ng/ml
Post-capture CORT 7.9 [6.4, 9.8] 23.1 [12.4, 42.9] NA
Stress-induced CORT 42.1 [35.9, 49.1] 84.6 [53.8, 132.6] NA
Females    
Post-capture CORT 9.5 [7.9, 11.4] 16.6 [8.0, 34.1] 13.7 [7.8, 23.9]
Stress-induced CORT 51.0 [43.4, 60.1] 107.2 [57.3, 200.5] 60.8 [37.5, 98.5]
  1. Data show back-transformed CORT concentrations (mean and 95% Bayesian credible intervals) of male and female African, Canary Islands and European stonechats during incubation and when feeding young. All individuals were caught without STI. As European males were always caught with STI, they were not included in the comparison with Canary Islands stonechats
