Eukaryotic composition in sediment and marine water fractions by DNA metabarcoding. v9_18SrRNA_sediment_water

The marine environment includes diverse microeukaryotic organisms that play important functional roles in the ecosystem. In this study DNA metabarcoding was performed to describe eukaryotic diversity in sediment and marine water fractions sampled from 2016 to 2018. The detection of potential pathogens, invasive organisms as well as the causative agents of harmful phytoplanktonic blooms were also performed. This study allowed the evaluation of the health of a marine ecosystem that directly affects the aquacultural sector with a zoonotic concern.

海洋环境中栖息着种类繁多的微真核生物（microeukaryotic organisms），它们在生态系统中发挥着关键的功能作用。本研究采用DNA元条形码（DNA metabarcoding）技术，对2016至2018年间采集的沉积物与海水组分样本中的真核生物多样性进行了表征。研究同时开展了潜在病原体、入侵生物以及有害藻华致病原的检测工作。本研究可对直接影响水产养殖业且存在人畜共患风险的海洋生态系统健康状况进行评估。
