Eighteen manuscripts of the meeting presentations were selected in this special issue. According to the four themes set in the ICBC meeting, this special issue include four sections, i.e., Coastal Biodiversity under Global Change, Adaptation and Evolution to Special Environment of Coastal Zone, Sustainable Utilization of Coastal Bioresources, and Coastal Biotechnology. Recent advances in these filed are presented.展开更多
