Abstract

The present study evaluated the possible occurrence of cryptic species among Merluccidae from Argentina by examining sequences of cytochrome c oxidase subunit I (coI) mtDNA. This approach can discriminate Merluccius hubbsi and Merluccius australis; specimens with morphological diagnostic characters of Merluccius patagonicus formed a cohesive cluster with M. hubbsi specimens. BIN analysis confirmed the effectiveness of barcoding within a global context.

摘要

本研究通过检测细胞色素c氧化酶亚基I（coI）线粒体DNA序列，评估了阿根廷无须鳕科中可能存在的隐存种。这种方法可以区分巴氏无须鳕和南方无须鳕；具有巴塔哥尼亚无须鳕形态诊断特征的标本与巴氏无须鳕标本形成了一个紧密的聚类群。BIN分析证实了条形码在全球范围内的有效性。
