Bleached corals rapidly recover when they touch genetic clones

AI Insight

Research has demonstrated that bleached coral can recover in as little as 4 weeks when it comes into physical contact with genetically identical coral colonies. The recovery mechanism involves the transfer of symbiotic algae from the healthy clone to the damaged coral, effectively repopulating the bleached tissue through direct contact. This algal transfusion process represents a previously unrecognized pathway for rapid coral recovery following bleaching events.

Why it matters

This discovery could inform new coral restoration strategies, particularly in areas experiencing frequent bleaching events due to climate change. The finding suggests that strategic placement of healthy coral fragments near bleached colonies of the same genetic lineage might accelerate reef recovery and improve survival rates during restoration efforts.
