摘要

我们报告了亚利桑那州维德河中存在Redeye Bass Microterus coosae的遗传和形态学证据,以前被认为是Smallmouth Bass Microtterus dolomieu。我们对亚利桑那州亚瓦派县上维德河野生动物区的15个个体进行了分生组织测量。侧线音阶、侧线以上音阶和侧线以下音阶的经线数据都与Redeye低音一致,而不是Smallmouth低音。我们分析了线粒体和核遗传数据,以确定历史上引入佛得角河的黑鲈鱼(Microterus属)物种之一是否是Redeye bass,以及它们是否在该系统中存在。我们从五个个体的鳍片段中提取DNA,用于NADH脱氢酶亚基2(ND2)线粒体基因的系统发育分析,并使用诊断性单核苷酸多态性(SNP)小组分析核DNA。ND2基因测序和系统发育分析结果表明,这些鱼类可能起源于阿拉巴马州、佐治亚州和田纳西州库萨河水系的本地Redeye Bass种群。同样,根据结构分析,从Verde河采集的五个个体的核SNP数据与Redeye-Bass参考基因型一致。这些结果支持了这样一种假设,即至少有一次在亚利桑那州的维德河引入黑鲈鱼,建立了一个以前未被识别的Redeye bass种群。需要进一步的工作来确定Redeye Bass在亚利桑那州的存在程度,Smallmouth Bass是否也存在于Verde河水系,以及Redeye低音和其他黑低音是否发生杂交。

A case of mistaken identity: Genetic and morphological evidence for the presence of Redeye Bass in the Verde River, Arizona
We report genetic and morphological evidence for the presence of Redeye Bass Micropterus coosae, in the Verde River of Arizona, previously thought to be Smallmouth Bass Micropterus dolomieu. We performed meristic measurements on 15 individuals sampled from the Upper Verde River Wildlife Area, Yavapai County, Arizona. Meristic data for lateral line scales, scales above lateral line, and scales below lateral line were all consistent with Redeye Bass and not Smallmouth Bass. We analyzed mitochondrial and nuclear genetic data to determine if one of the black bass (Genus Micropterus) species historically introduced to the Verde River was Redeye Bass and that they persist in the system. We extracted DNA from fin clips of five individuals for phylogenetic analysis of the NADH dehydrogenase subunit 2 (ND2) mitochondrial gene and for analysis of nuclear DNA using a diagnostic Single Nucleotide Polymorphism (SNP) panel. Results of the ND2 genetic sequencing and phylogenetic analysis indicated that these fish likely originated from native Redeye Bass stock from the Coosa River system of Alabama, Georgia, and Tennessee. Similarly, nuclear SNP data from the five individuals collected from the Verde River aligned with Redeye Bass reference genotypes based on STRUCTURE analysis. These results support the hypothesis that at least one of the introductions of black bass in Arizona’s Verde River founded a previously unrecognized population of Redeye Bass.  Further work is needed to determine the extent of the Redeye Bass presence in Arizona, whether Smallmouth Bass are also present in the Verde River system, and if hybridization of Redeye Bass and other black basses is occurring.

期刊介绍: Journal of Fish and Wildlife Management encourages submission of original, high quality, English-language scientific papers on the practical application and integration of science to conservation and management of native North American fish, wildlife, plants and their habitats in the following categories: Articles, Notes, Surveys and Issues and Perspectives. Papers that do not relate directly to native North American fish, wildlife plants or their habitats may be considered if they highlight species that are closely related to, or conservation issues that are germane to, those in North America.
