Molecular identification and species delimitation of Rhinogobius (Gobiiformes: Oxudercidae) gobies across Eurasia

This dataset employs mitochondrial COI barcoding, phylogenetics, and multiple species delimitation methods to resolve the identity of invasive populations in the Caspian Sea basin and assess Eurasian diversity.本数据集采用线粒体COI条形码（mitochondrial COI barcoding）技术、系统发育学分析与多种物种界定方法，以厘清里海盆地入侵种群的物种身份，并评估欧亚大陆的物种多样性。
