Edited by T.N. Dautova. Vladivostok: Dalnauka, 2016. 180 p. The book summarizes results of the workshop in the area of biodiversity, marine ecology and biogeography of the South China Sea and adjacent regions held on December 21–22 in Nha Trang, Vietnam. It discusses the synthesis of the biological data concerning the region and surrounding environments, such as marine currents, sedimentation, eutrophication and pollution. The special attention is paid to the policy making for science-based conservation and rational using of the marine ecosystems along with the Asia-pacific coasts. Organizing Committee Dr. Tatiana N.
