Outbreaks of large-scale green tides formed by Ulva prolifera in the Yellow Sea (YS) cause heavy ecological damages and huge economic losses. However, the ecological consequences of green tides remain poorly understood due to the lack of knowledge on the settlement region of massive green algae floating in the YS. In this study, we established a method to trace the settlement region of floating green algae, using 28-isofucosterol preserved in sediment as the specific biomarker for green algae. Sterols including 28-isofucosterol in surface sediment samples collected during an investigation in the YS and the Bohai Sea (BS) in August 2015 were analyzed using gas chromatography coupled with a mass spectrometer (GC-MS). Based on the content of 28-isofucosterol in sediment samples, the potential settlement region of fl oating green algae was identifi ed in the sea area southeast to the Shandong Peninsula around the sampling site H06 (122.66°E, 36.00°N). This paper presents a first result on the settlement region of floating green algae in the YS for providing a solid basis to elucidate the ecological consequences of green tides in the area.

浒苔(***)绿潮在黄海连年引发严重的环境灾害,然而对于浒苔及其近缘种缘管浒苔(***)的鉴定,仍缺少稳定可靠的分子标记。有文献提出tuf A可有效区分二者,本文选择前期鉴定为LPP簇(包含浒苔与缘管浒苔)的17个样本与一个Ulva sp.样本,对tuf A的适用性进行了评价。结果证明,tuf A实际上无法区分浒苔与缘管浒苔,深入分析发现,其错误结论源自对样本的错误鉴定。我们认为,应基于两个近缘种的叶绿体基因组序列变异区,开发可靠的新标记。
