摘要： 随着生物技术的发展, 环境DNA(environmental DNA, eDNA)方法被广泛应用到水生生物多样性研究中。与传统方法相比, eDNA方法具有灵敏度高、省时省力、对调查的生物对象无损伤等优点, 并可以快速地检测出调查区域内生物种类组成、稀有物种等。但目前eDNA方法在极地海洋生物多样性研究中的应用极少, 本文综述了国内外eDNA的研究现状, 分析了该方法的优点与缺点, 结合北极地区海洋鱼类生物多样性研究现状, 展望了eDNA方法在北极地区海洋鱼类生物多样性研究中的应用潜力以及可能面临的相关挑战。

Abstract:

With the development of biotechnology, environmental DNA (eDNA) methods have become widely used in aquatic biodiversity research. Compared with traditional methods, eDNA methods can quickly detect species composition without damaging the biological samples and have the advantages of high sensitivity, saving time and labor saving, and preserving sample integrity. However, they are currently less widely used in polar marine biodiversity research. This article reviews the current status of eDNA methods, analyzes the advantages and disadvantages, considers the current status of marine fish biodiversity research in the Arctic, and discusses the potential of using eDNA methods in Arctic marine fish biodiversity research and the related challenges.
