Abstract

Abstract Two mitochondrial genes (cytochrome oxidase I and cytochrome b) were examined to compare an isolated population of the Italian minnow in the central Apennines to other populations in the species’ range (Po plain) and other European minnow species. Both mitochondrial markers showed a new haplotype, fixed in a sample of 30 specimens, never observed in the main species distribution range, and ostensibly divergent from other Italian minnow haplotypes. The result suggests a long history of isolation, probably preceding the Holocene retreat northwards of the Po River. This relict population is now at serious extinction risk owing to habitat loss and predation by alien trout restocked into the wild for recreational fishing purposes.

线粒体DNA表明，亚平宁（意大利）中部一个孤立的意大利鲇种群（Phoxinus lumaireul Schinz，1840）（Teleostei：鲤鱼科）具有独特性

摘要检测了两个线粒体基因（细胞色素氧化酶I和细胞色素b），以将亚平宁中部的意大利鲇分离种群与该物种范围内的其他种群（Po平原）和其他欧洲鲇物种进行比较。这两种线粒体标记都显示出一种新的单倍型，固定在30个样本中，从未在主要物种分布范围内观察到，表面上与其他意大利米诺单倍型不同。这一结果表明，可能在蒲河以北的全新世消退之前，有着漫长的与世隔绝的历史。由于栖息地的丧失和为休闲捕鱼目的重新放养到野外的外来鳟鱼的捕食，这种残余种群现在面临着严重的灭绝风险。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
