Hawaiian Corals Show Uneven Heat Tolerance Tied to Past Conditions

Original: Hawaiian Corals Show Uneven Heat Tolerance Linked to Environmental History

New research indicates that coral reefs across Hawaii differ widely in their ability to withstand marine heatwaves, with variations traced to each reef's environmental history rather than geography alone. Scientists say corals exposed to past temperature stress may cope better with warming waters, findings that could shape which reefs are prioritised for protection and restoration as ocean temperatures continue to rise.

Why now: Rising ocean temperatures are making coral heat tolerance a pressing conservation question.
