Hormones and Fitness: Evidence for Trade-Offs in Glucocorticoid Regulation Across Contexts

Glucocorticoid hormones are important regulators of metabolic processes, and of the behavioral and physiological responses to stressors. Within-population variation in circulating glucocorticoids has been linked with both reproductive success and survival, but the presence and direction of relationships vary. Although conceptual models suggest the potential for interactions between glucocorticoid secretion under acute stress and non-acute stress...
