An experimental test of the effect of brood size on glucocorticoid responses, parental investment, and offspring phenotype.

General and comparative endocrinology - 1 Jun 2017

Vitousek Maren N, Jenkins Brittany R, Hubbard Joanna K, Kaiser Sara A, Safran Rebecca J

Abstract excerpt

Because elevated glucocorticoid levels can impair reproduction, populations or species that engage in particularly valuable reproductive attempts may down-regulate the glucocorticoid stress response during reproduction (the brood value hypothesis). It is not clear, however, whether individuals rapidly modulate glucocorticoid responses based on shifting cues about the likelihood of reproductive success. By...
