Measuring Physiological Stress in Mammals: How Metabolism Influences Fecal Glucocorticoid Levels

The concept of physiological stress is widely used but poorly understood. In mammals, physiological stress is often assessed noninvasively based on the concentration of glucocorticoid hormone (i.e., cortisol, corticosterone) metabolites in feces (i.e., fecal glucocorticoids—FGCs). Yet, it remains unclear if FGC level...
