Istwa nan ekspoze: Koray jeneralman egzije chenn etwat de sèten kondisyon pou li siviv (pa egzanp, tanperati, salinite, limyè), men kèk koral te aklimate a kondisyon ki bay anpil strès nan limit eksteryè chenn yo. Yon istwa nan ekspoze a tanperati ki wo ka enfliyanse tolerans tèmik nan koray ak amelyore detèminasyon yo. Pou egzanp, koray sibi pi cho pase tanperati mwayèn anvan yon evènman blanchi ka gen plis tèmik toleran konpare ak koray ki pa te pre-ensiste (Middlebrook et al. 2008). Koray an sante nan zòn kote variation tèmik se wo (egzanp, nan lakou back-Reef) kapab tou gen plis rezistan a estrès tèmik (McClanahan et al. 2007; Oliver ak Palumbi 2011). Anplis de sa, pati nan resif ki regilyèman eksperyans kondisyon estrès chalè, tankou plat Reef ak krèt, yo ka peple pa koray ki pi toleran ak reziste nan ensiste.

History of exposure: Corals generally require narrow ranges of certain conditions to survive (e.g., temperature, salinity, light), but some corals have acclimatized to highly stressful conditions at the outer limits of their ranges. A history of exposure to high temperatures can influence the thermal tolerance of corals and enhance their resilience. For example, corals subjected to warmer than average temperatures prior to a bleaching event can be more thermally tolerant compared to corals that have not been pre-stressed (Middlebrook et al. 2008). Healthy corals in areas where thermal variability is high (e.g., in back-reef lagoons) may also be more resistant to thermal stress (McClanahan et al. 2007; Oliver and Palumbi 2011). Additionally, parts of reefs that regularly experience heat stress conditions, such as reef flats and crests, may be populated by corals that are more tolerant of and resistant to stresses.
