Coral larval settlement preferences linked to crustose coralline algae with distinct chemical and microbial signatures

Abstract The resilience of coral reefs is dependent on the ability of corals to settle after disturbances. While crustose coralline algae (CCA) are considered important substrates for coral settlement, it remains unclear whether coral larvae respond to CCA metabolites and microbial cues when selecti...
