High-Resolution Imaging Reveals Three-Stage Coral Fragment Attachment

The peer-reviewed work pinpoints species-level differences that can steer more effective reef restoration.

Overview

  • Published in Royal Society Open Science, the QUT-led study identified an immune and tissue transition, soft-tissue anchoring, and skeleton-building via a specialized appendage as the conserved attachment sequence.
  • Advanced microscopy captured cellular-scale activity as fragments of Montipora mollis, Pocillopora verrucosa and Acropora millepora established stable contact with reef substrates.
  • Structural variation in the attachment appendage shaped attachment speed and strength, with Montipora mollis forming faster, stronger bonds than Pocillopora verrucosa.
  • Mesenterial filaments were found to help prepare fragments for attachment by digesting unneeded tissues, indicating a larger role in recovery and resilience.
  • Authors say the findings support targeted selection and prediction of corals likely to establish in specific environments, informing programs backed by RRAP and Australian Government funding.
