Abstract
研究使用环境DNA宏条形码(eDNA metabarcoding)检测洱海鱼类多样性,探索适用于洱海鱼类多样性监测和保护的新方法。通过水样采集、过滤、eDNA提取、遗传标记扩增、测序与生物信息分析的环境DNA宏条形码标准化分析流程,从洱海16个采样点中获得可检测的9个采样点数据,共检测出17种鱼类,其中土著种5种、外来种12种;鲫(Carassius auratus)、鳙(Hypophthalmichthys nobilis)、麦穗鱼(Pseudorasbora parva)、泥鳅(Misgurnus anguillicaudatus)和食蚊鱼(Gambusia affinis)为优势种。研究结果表明虽然环境DNA宏条形码无法完全替代传统的鱼类监测方法,但作为一种新兴的生物多样性监测手段,其可用于快速检测洱海鱼类多样性及其空间分布
