Abstract:Upper lethal temperature tolerances of reef corals in Hawaii and at
Enewetak, Marshall Islands, were determined in the field and under controlled
laboratory conditions. Enewetak corals survived in situ temperatures of nearly
34° C, whereas 32° C was lethal to Hawaiian corals for similar short-term exposures.
Laboratory determinations indicate that the upper thermal limits of Hawaiian corals
are approximately 2° C less than congeners from the tropical Pacific. Differences in
coral thermal tolerances correspond to differences in the ambient temperature
patterns between geographic areas.
