A corrigendum on
Corticosterone Concentrations Reflect Parental Expenditure in Contrasting Mating Systems of Two Coucal Species
by Goymann, W., Trappschuh, M., and Urasa, F. (2017). Front. Ecol. Evol. 5:15. doi: 10.3389/fevo.2017.00015
In the original article, there was an error. In the last paragraph of the Results section on page 7 we reported the results of baseline corticosterone concentrations in relation to the number of fledglings. In the statistical results we accidentally stated “feeding rate slope” when actually the slope of the number of fledglings was meant.
A correction has been made to the results section, page 7, last paragraph:
Baseline corticosterone concentrations of parenting male black coucals (N = 29), parenting female white-browed coucals (N = 19), and parenting male white-browed coucals (N = 14) were unrelated to the number of fledglings (male black coucals: number of fledglings = −0.007 [−0.031 to 0.016], P(β) = 0.26; time between sampling and bleeding: slope = 0.16 [−0.10 to 0.43], P(β) = 0.89; marginal and conditional R2 = 0.02; female white-browed coucals: number of fledglings = 0.02 [−0.05 to 0.08], P(β) = 0.68; time between sampling and bleeding: slope = 0.06 [−0.27 to 0.39], P(β) = 0.64; marginal and conditional R2 = 0.01; male white-browed coucals: number of fledglings = 0.01 [−0.05 to 0.08], P(β) = 0.65; time between sampling and bleeding: slope = −0.01 [−0.38 to 0.36], P(β) = 0.46; marginal R2 = 0.004 and conditional R2 = 0.05).
The authors apologize for this semantic error and state that this does not change the scientific conclusions of the article in any way.
The original article has been updated.
