Song complexity, song rate, and variation in the adrenocortical stress response in song sparrows (Melospiza melodia).

General and comparative endocrinology - 1 May 2014

Grunst Melissa L, Grunst Andrea S

Abstract excerpt

Physiological mechanisms that pleiotropically affect condition, life-history decisions, and fitness may covary with the expression of sexually selected ornaments. The adrenocortical stress response regulates energy balance, controls vertebrate responses to survival threats, and may divert energy expenditure away from investment in costly sexual displays. Further, developmental stress may induce correlations...
