由于昆虫进化的早期差异、独特的水生幼虫阶段和较低的扩散能力，许多蚂蚁物种表现出准确反映地质历史和古气候变化的遗传结构。本研究调查了一种生活在日本不同淡水栖息地的粉虱Edyonurus yoshidaeTakahashi的遗传特征。从日本109个采样点的209份标本中扩增出线粒体细胞色素C氧化酶亚基I(COI)和16S核糖体RNA(16S RRNA)基因序列。共检测到145个单倍型，其中9个谱系表现出地理地域性，其中一个谱系是琵琶湖特有的。单倍型网络为“瓶颈型”，既包括星状结构，也包括缺失(或未观察到)的单倍型。总而言之，单倍型网络和FST值表明，福岛群体(支系I)与九州岛上的群体在基因上是不同的，九州岛与福岛岛之间由Gotonada海隔开。E的共同祖先。据估计，日本的Yoshidaelinee年龄偏离了1.14兆年(95%的最高后验密度区间，0.55-1.78 Ma)，在中更新世至晚更新世期间产生了更多的区域遗传差异。日本东部和西部的不同基因谱系被日本中部的近木三角地区隔开。栖息地的遗传多样性。Yoshidae在中更新世和晚更新世期间增加，当时日本群岛的地壳运动和气候变化同时发生。
Because of their early divergence in insect evolution, unique aquatic larval stage, and low dispersal ability, many mayfly species exhibit genetic structures that accurately reflect geological history and paleoclimatic changes. The present study investigated the genetic characteristics ofEcdyonurus yoshidaeTakahashi (Ephemeroptera: Heptageniidae), a mayfly that inhabits a variety of freshwater habitats in Japan. Mitochondrial cytochrome c oxidase subunit I (COI) and 16S ribosomal RNA (16S rRNA) gene sequences were generated from 209 mayfly specimens that were collected from 109 sites in Japan. A total of 145 haplotypes were detected, and nine of the lineages exhibited geographical regionality, with one lineage being endemic to Lake Biwa. The haplotype network was “bottleneck type” and included both star‐like structures and missing (or unobserved) haplotypes. Together, the haplotype network andFSTvalues indicated that the Fukuejima Island group (Clade I) was genetically distinct from groups on the island of Kyushu, which is separated from Fukuejima Island by the Gotonada Sea. The common ancestor ofE. yoshidaelineages in Japan was estimated to have diverged 1.14 mega‐annum (Ma) (95% highest posterior density interval, 0.55–1.78 Ma), and more regional genetic diversities were generated during the Middle to Late Pleistocene. Genetically distinct lineages of eastern and western Japan were separated by the Kinki Triangle region in central Japan. The genetic diversity of the habitat generalistE. yoshidaeincreased during the Middle and Late Pleistocene, when crustal movement and climate change in the Japanese archipelago occurred simultaneously.
