2021 Annual Research Progress ( HK Branch)

Distinguished Seminar Series 香港分部杰出学者講座 217 Prof. Daniel Schlenk University of California, Riverside, USA 美国加州大学河滨分校 Intro: Prof. Daniel Schlenk has conducted both the laboratory and field studies using the pelagic fish species as the model subjects. Laboratory experiments indicated that oil-exposure led to the genetic and epigenetic alteration of the embryonic and larval, correlating with the cardiac and neurobehavioral modifications in surviving adults. Field studies with wild-caught adult mahi (the model fish) of post oil-exposure indicated the same molecular signatures and physiological predictions observed in laboratory studies with embryos/larvae. Prof. Schlenk’s talk gave us a comprehensive understanding of the adverse impact of oil on fish population. His study highlights the importance of both laboratory and field studies for the prediction and risk assessment of environmental contaminants. This impressive talk also raises our awareness about the environmental protection. 内容摘要:Daniel Schlenk教授以实验室研 究和实地研究相结合,把中上层鱼类作 为模型实验对象进行了系统比较研究。 实验室结果发现,暴露在石油污染物中 的鱼胚胎和幼体在遗传和表观遗传方面 发生了改变,这个改变与幸存的成年鱼 的心脏功能和神经行为改变密切相关。 而实地研究则把捕获的野生成年mahi鱼 (一种模型鱼类)暴露于石油中,然后进行 分析。实地研究结果与在实验室研究中 观察到的胚胎/幼体显示的分子特征和生 理预测相同。Schlenk 教授的演讲让我们 全面了解了石油污染物对鱼类种群的不 利影响。此研究突出了实验室研究和实 地研究对环境污染物的预测和风险评估 的重要性。这场演讲大大提高了听众的 环境保护意识。 Predicting Population Impacts of Oil on a Pelagic Fish Species in the Gulf of Mexico, USA 預測石油對美国墨西哥灣中上層鱼类種群的影响 Distinguished Seminar Series 3 香港分部第三次杰出学者讲座 Date 日期 : 10 August 2021 (Wednesday) 2021年8月10日 (星期三) Zoom Meeting 线上平台 ID : 964 8986 2982 Participants 参会者 : 77
