DNA-based taxonomy of a mangrove-associated community of fishes in Southeast Asia

Abstract The Merbok Estuary comprises one of the largest remaining mangrove forests in Peninsular Malaysia. Its value is significant as it provides important services to local and global communities. It also offers a unique opportunity to study the structure and functioning of mangrove ecosystems. H...
