Introduction to the Symposium: Stress Phenotype: Linking Molecular, Cellular, and Physiological Stress Responses to Fitness

Although most organisms respond to environmental and social stressors by initiating a stress response that is expected to increase fitness, we currently lack information about how the stress response is integrated across levels of biological organization. Organismal biologists and physiological ecologists have tended to focus on questions related to how the glucocorticoid stress response varies across ecological contexts and is related to...
