The common measure of physiological stress in organisms is often assessed through the level of corticosterone or other stress hormones in the bloodstream. These indicators reflect the physiological changes occurring in response to environmental challenges, such as predator exposure or resource scarcity. High levels of these hormones can be detrimental, affecting behavior, reproduction, and overall health. Additionally, measuring physiological stress can provide insights into the well-being of individuals and populations, making it a valuable tool in ecological research and conservation practices.
