Abstract

The paper gives the results of the first studies on the molecular divergence between native and non-native populations of Speonomus normandi hydrophilus (Jeannel, 1907). This species is endemic to Massif Arize in the Central Pyrenees (France), and represents highly specialised organisms that live underground. In 1982, one hundred specimens of S. normandi hydrophilus had been experimentally introduced into the Dzwonnica Cave (Poland). Since then, a numerous population has developed in the Towarna-Dzwonnica cave system, and the neighbouring Cabanowa Cave. After almost 40 years of isolation between native and non-native populations, the genetic variations were examined using the COI and 28S rDNA genes. Analyses of the haplotypes of 28S showed one common haplogroup, which confirms the origin of the Polish group. The differentiation of haplotypes for the COI marker was high for both the French and Polish populations. Altogether 18 haplotypes of this marker have been detected, 12 in the French population and 9 in the Polish. However, only a portion of the haplotypes is shared between the native and introduced population.

隔离生活近40年：法国和波兰洞穴甲虫Speonomus normandi hydrophilus种群28S rDNA和COI序列的分子差异（Jeannel，1907）

本文给出了首次研究正常嗜水气单胞菌（Speonomus normandi hydrophilus）本地和非本地种群之间分子差异的结果（Jeannel，1907）。该物种是中比利牛斯山脉（法国）Massif Arize的特有物种，代表了生活在地下的高度专业化的生物。1982年，在Dzwonnica洞穴（波兰）实验性地引入了100个嗜水气单胞菌标本。从那时起，Towarna Dzwonnica洞穴系统和邻近的Cabanowa洞穴中出现了大量人口。在本地和非本地种群之间隔离了近40年后，使用COI和28S rDNA基因检测了遗传变异。对28S单倍型的分析显示了一个常见的单倍型群，这证实了波兰组的起源。COI标记的单倍型分化在法国和波兰人群中都很高。共检测到18种该标记的单倍型，其中12种在法国人群中，9种在波兰人群中。然而，只有一部分单倍型在本地和引进种群之间共享。

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.
