NEW PAPER: HORMONE RESPONSES IN BIRDS

2/6/2017

 
Picture
New paper published in General and Comparative Endocrinology, "An experimental test of the effect of brood size on glucocorticoid responses, parental investment, and offspring phenotype". We demonstrate in barn swallows that while under moderately challenging environmental conditions brood size manipulations had context-dependent effects on female parental investment, and influenced nestling phenotype, maternal glucocorticoid levels were not modulated based on brood value but were individually consistent features of phenotype during breeding. 🔗

​This research was led by Maren Vitousek (Cornell University) and Rebecca Safran (University of Colorado-Boulder).
