Despite theoretical predictions, little is known about how individuals will respond to unpredictable short-lived stressors, such as thermal events. We examine the primary neuroendocrine response of coral reef fish populations from the AZles Eparses rarely exposed to anthropogenic stress, but that experienced different thermal histories. Skunk anemonefish, Amphiprion akallopisos, showed different cortisol responses to a generic stressor between islands, but not along a latitudinal gradient. Those populations previously exposed to higher maximum temperatures showed greater responses of their HPI axis. Archive data reveal thermal stressor events occur every 1.92-6 yr, suggesting that modifications to the HPI axis could be adaptive. Our results highlight the potential for adaptation of the HPI axis in coral reef fish in response to a climate-induced thermal stressor. specialized Climate change Phenotypic plasticity HPI axis Thermal stressor Cortisol Acclimation OCEAN INDIEN MOZAMBIQUE CANAL GLORIEUSES ILE JUAN DE NOVA ILE EUROPA ILE 034 032 021 34 4 1255-1260 2015 0722-4028 https://www.documentation.ird.fr/hor/fdi:010065490 10.1007/s00338-015-1333-8 0722-4028 [F B010065490] https://www.documentation.ird.fr/hor/fdi:010065490 https://www.documentation.ird.fr/intranet/publi/2015/12/010065490.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-01-14 2017-08-23 fdi:010065490 fre
