Information on diversity indices and abundance of individual species is crucial for the assessment of ecosystem health, especially for endangered ecosystems such as coral reefs. The application of environmental DNA (eDNA) to monitor coral biodiversity is, however, just beginning to come into focus for marine biologists. In this study, an eDNA metabarcoding approach of seawater samples in three different reefs on Koh Pha-ngan, Thailand, was compared with simultaneously collected visual census data. In addition, differences...
