科学家根据DNA和物理特征证实,格鲁吉亚河流中有两个新的黑贝斯物种,不同于红眼贝斯。 Scientists confirm two new black bass species in Georgia rivers, distinct from redeye bass, based on DNA and physical traits.

格鲁吉亚大学和伙伴机构的研究人员已经确定了两种新的黑贝斯物种——Bartram的贝斯和Altamaha Bass——以前被误认为红眼贝斯。 Researchers from the University of Georgia and partner institutions have identified two new black bass species—Bartram's bass and Altamaha bass—previously mistaken for redeye bass. 尽管目击可追溯到1980年代,但详细的物理和遗传分析证实了它们的独特地位。 Though sightings date back to the 1980s, detailed physical and genetic analysis confirmed their distinct status. 小组利用线粒体DNA和核基因组比较,排除了混合和记录的独特特征。 Using mitochondrial DNA and nuclear genome comparisons, the team ruled out hybridization and documented unique traits. 两种物种都居住在河流池和岩石群,在改变的生境中生存。 Both species inhabit river pools and rocky shoals, surviving in altered habitats. 这项研究在祖塔卡市出版,得到了国家野生动物赠款的支持,标志着北美鱼类分类学的重大更新。 The study, published in Zootaxa, was supported by state wildlife grants and marks a significant update to North American fish taxonomy.
