Host species as key drivers of Symbiodiniaceae assemblages: Coral and free-living diversity in a Southwestern Atlantic oceanic island

Key Points

• Symbiodiniaceae assemblages significantly vary based on coral species present in the environment, highlighting species-specific interactions.
• In this study, a diverse range of coral species was observed, contributing to distinct symbiodiniaceae assemblages across different habitats.
• Observational analysis across a Southwestern Atlantic oceanic island assessed coral and free-living diversity to understand ecological roles.
• This research may enable better conservation strategies by illustrating how host species influence symbiodiniaceae diversity.
