claimCirculating glucocorticoid levels are likely regulated in part based on an individual’s proximity to energetic crisis, which is identified as the perturbation resistance potential (PRP).

claimResponsiveness to cues of an impending energetic crisis functions similarly to a smoke detector, where the cost of failing to respond is high compared to the cost of a false activation.

claimPerturbation resistance potential (PRP) is defined as an individual's proximity to energetic crisis, which helps regulate circulating glucocorticoid levels.

claimAnimals should ideally respond to cues that reliably reflect or predict an impending energetic crisis by elevating glucocorticoids.

claimAn organism engaging in decision-making about activating the Emergency Life-History Stage (ELHS) must navigate the risks of remaining in its normal seasonal life-history stage to face an energetic crisis unprepared versus reducing the duration over which such a crisis can be survived.

claimIn the context of error management theory, an energetic crisis or low probability of reproductive potential (PRP) is considered the critical risk associated with a false negative error, defined as a non-response to a real threat.

claimThe reliability of environmental cues as indicators of Predictive Regulatory Potential (PRP) varies, and these cues can either reliably signal an impending energetic crisis or lead to errors in physiological decision-making.

perspectiveThe authors propose that a model utilizing error management theory could interpret physiological data by treating energetic crisis or low PRP as the critical risk of a false negative error, defined as a non-response to a real threat.

perspectiveThe authors propose examining two specific mechanisms to understand how animals inform themselves about the status of their perturbation resistance potential (PRP) and the probability of energetic crisis: (1) elevation in glucocorticoids as an endocrine 'decision,' and (2) error management strategies in evaluating responsiveness to cues.

claimAnimals elevate glucocorticoids in response to cues that reliably reflect or predict an impending energetic crisis.

claimOrganisms exhibit responsiveness to cues of an impending energetic crisis, which functions similarly to an over-response bias.
