Altogether 149 algal species were detected in this study, and 59 taxa have been reported to form resting stages. A total of 454 eukaryotic algal OTUs were detected, which belonged to 31 classes of 9 phyla. Biogenic elements including total organic carbon (TOC), total nitrogen (TN), total phosphorus (TP), biogenic silicon (BSi), and moisture content (MC) were analyzed. Diversity and community structure of eukaryotic microalgae in surface sediments were assessed by metabarcoding V4 region of the 18S rDNA, focusing on the distribution of HAB species. In this study, surface sediment samples were collected in the four sea areas along the southeast Chinese coasts, including Dafeng Port (DF) in the southern Yellow Sea, Xiangshan Bay (XS), Funing Bay (FN), and Dongshan Bay (DS) in the East China Sea. ![]() The distribution of resting stages in sediments especially those of HAB species can make good predictions about the potential risk of future blooms, however with limited reports. Resting stages are regarded as the “seed bank” of algal blooms, and play an important role in initiating HABs. In the past three decades, harmful algal blooms (HAB) have become more frequent and widespread in southeast Chinese sea areas. 2Southern Marine Science and Engineering Guangdong Laboratory, Zhuhai, China.1College of Life Science and Technology, Jinan University, Guangzhou, China. ![]() Zhaohui Wang 1†, Liang Peng 1†, Changliang Xie 1†, Wenting Wang 1, Yuning Zhang 1, Lijuan Xiao 1*, Yali Tang 1* and Yufeng Yang 1,2 ![]()
