Microbiome of CCA species from different habitats
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 selecting sites for attachment and metamorphosis. This study tested the settlement preferences of an abundant coral species (Acropora cytherea) against six different CCA species in laboratory assays, and compared these preferences with the metabolome and microbiome characterizing the CCA.
