referenceWhen an animal relies on cues indicating a threat to Potential Reproductive Potential (PRP) and responds with anticipatory elevation in glucocorticoid levels, it can lead to Emergency Life History Stage (ELHS) activation and/or homeostatic overload as described in the Reactive Scope model.
referenceThe Reactive Scope model, introduced by Romero et al. (2009), serves as a complementary framework to the allostatic load model.
claimL. M. Romero, M. J. Dickens, and N. E. Cyr introduced the 'reactive scope model' as a framework integrating homeostasis, allostasis, and stress in a 2009 paper in Hormones and Behavior.
claimIn the reactive scope model, acute responses are visualized as spikes in the reactive homeostasis range.
referenceIn the reactive scope model, acute responses are visualized as spikes in the reactive homeostasis range, and both the frequency and duration of these acute responses are expected to reduce the threshold at which homeostatic overload occurs, as noted by Romero et al. (2009).
claimDiscussions of the reactive scope model have been dominated by glucocorticoid physiology (Blas and Fairhurst, 2022).
claimBoth the allostatic load framework and the Reactive Scope model incorporate the concept of a threshold, though they apply the concept differently.
claimBlas and Fairhurst (2022) note that discussions of the reactive scope model have been dominated by glucocorticoid physiology.
referenceThe Reactive Scope model serves as an alternative to the allostatic load model and was first detailed in a 2009 paper by Romero et al.
referenceThe Reactive Scope model focuses on the physiological actions of endocrine mediators and the mechanisms by which adaptive responses indicate and generate physiological damage, excluding Eg and PRP components.
referenceThe reactive scope model is designed to consider the function and dysfunction of diverse mediators, though it is often used to understand glucocorticoid hormone function (Romero et al., 2009).

referenceRiede, S. J., van der Vinne, V., and Hut, R. A. (2017) proposed the 'reactive scope model' in their paper 'The flexible clock: predictive and reactive homeostasis, energy balance and the circadian regulation of sleep-wake timing', which integrates the concepts of homeostasis, allostasis, and stress.
