摘要

摘要Troglichthys (= Amblyopsis) rosae (Ozark Cavefish)目前在Ozark高地生态区内的83个地点被发现。我们在尼奥肖河(Delaware County, OK)西侧的切罗基大湖中的一个新位置发现了一条洞穴鱼，它位于欧扎克洞穴鱼范围的西北边缘。线粒体ND2基因的检测支持该标本是一条欧扎克洞穴鱼，但与其他遗传样本不同(4.6-9.2%的成对距离)，可能代表一个独特的种群。未来的研究应该集中在扩大取样工作和对欧扎克洞穴鱼进行广泛的遗传分析。

A Fisherman's Tale: An Unusual Observation of the Ozark Cavefish, Troglichthys (= Amblyopsis) Rosae (Eigenmann)

Abstract Troglichthys (= Amblyopsis) rosae (Ozark Cavefish) is currently known from 83 locations within the Ozark Highlands ecoregion. We found a cavefish at a new location in the Grand Lake O' the Cherokees on the western side of the Neosho River (Delaware County, OK), which is on the northwest periphery of the Ozark Cavefish range. Examination of the mitochondrial ND2 gene supports that the specimen is an Ozark Cavefish, but distinct (4.6–9.2% pairwise distance) from other specimens that have been genetically sampled, and could represent a unique population. Future research should focus on expanding sampling efforts and conducting a range-wide genetic analysis of the Ozark Cavefish.
