Abstract The recovery of coral populations depends on successful settlement and survivorship of recruits. Sedimentation is a major stressor for corals, yet information on its influence on Caribbean juvenile corals is limited. We evaluated larval settlement and recruit survival under sediment burial across six Caribbean species and multiple early life stages. Burial of suitable substrata under 2 mm of sediment reduced settlement probability to ≤25% and 4 mm suppressed settlement entirely.

| Frontiers in Marine Science
Abstract Over recent decades, coral reefs worldwide have experienced substantial declines in coral cover as a result of interacting global and local stressors. On Florida’s coral reef, coral cover has declined by over 70%, in recent decades, coinciding with pronounced shifts in benthic community composition.
