Microbiome Diversity in Pacific Coral Reefs

The Tara Pacific expedition, the largest survey of Pacific Ocean corals, unveiled greater genetic diversity than previously known. Researchers collected 58,000 samples from 249 locations, discovering 542,399 DNA sequences among bacteria.

This challenges existing estimates, suggesting global reef diversity may reach 2.8 million amplicon sequence variants (ASVs). Understanding the links between diversity, reef function, and health is crucial in the face of climate change and pollution.

Another study focused on bacteria associated with corals, uncovering their role in providing vitamins and amino acids crucial for coral health and immunity.

The expedition, supported by the Tara Ocean Foundation, offers valuable insights into coral biology and reef ecosystems.
