Overview

Ecological analyses reveal dead coral skeletons deter recruitment in reefs impacted by bleaching events.

Key Points

  • This research investigates how dead Pocillopora corals influence coral community recovery after bleaching.
  • Examined dead Pocillopora colonies and their skeletal structure using high-resolution microscopy
  • Analyzed ecological impacts of dead corals on reef sedimentation and invertebrate colonization
  • Assessed coral recruitment on settlement tiles versus dead skeletons
  • Coral recovery has not begun three years post-bleaching due to dead coral retention
  • Dead Pocillopora were colonized by macroalgae and unique invertebrate assemblages
  • Bioerosion of dead coral branches was detected, indicating structural decay
