Hawaiian Corals Reveal Surprising Heat Resilience, Offering Hope Amidst Warming Oceans
A new study by Florida Atlantic University (FAU) researchers has found that Hawaiian corals respond differently to ocean heat based on their species and where they grew up, offering a glimmer of hope for future conservation efforts. Published on October 13, 2026, in 'Scientific Reports', the study focused on two common Hawaiian corals, 'Montipora capitata' (rice coral) and 'Porites compressa' (finger coral), from two distinct Oʻahu bays: the warmer, sheltered Kāneʻohe Bay and the cooler, more exposed Kailua Bay. The findings revealed that 'Porites compressa' from the cooler Ulupaʻu area in Kailua Bay showed much stronger heat resistance compared to those from Kāneʻohe Bay or even 'Montipora capitata' from either location, indicating that past environmental conditions play a crucial role in how corals handle heat stress.
