Hawaiian coral heat tests find species and location differences
A controlled study found greater measured heat tolerance in one Porites compressa population, a distinction that could help guide coral restoration choices.
Hawaiian corals tested under controlled heat stress showed different levels of tolerance by species and source location, according to a study reported on 13 October. Porites compressa collected at Ulupaʻu in Kailua Bay performed better than the other tested populations, a finding that could inform which corals are chosen for restoration.
How the two Hawaiian coral species responded
Researchers tested Porites compressa and Montipora capitata from Kāneʻohe Bay and nearby Kailua Bay, measuring photosynthetic efficiency during heat stress. The study found significantly greater measured tolerance in the Ulupaʻu Porites compressa than in Porites compressa from Kāneʻohe Bay or any tested Montipora capitata population. Montipora capitata showed similar tolerance across the two bays.
The authors say differences among species and source populations could guide coral selection for restoration. The tests measured physiological responses under controlled conditions; they did not assess whether those corals would survive on a reef or succeed after restoration.
