The Taebaek Mountains in Korea serve as the most apparent biogeographic barrier for Korean freshwater fishes,resulting in 2 distinct ichthyofaunal assemblages on the eastern(East/Japan Sea slope)and western(Yellow Sea and Korea Strait slopes)sides of the mountain *** nearly 100 species of native primary freshwater fishes in Korea,only 18 species occur naturally on both sides of the mountain ***,there are 5 rheophilic species(Phoxinus phoxinus,Coreoleuciscus splendidus,Ladislavia taczanowskii,Iksookimia koreensis and Koreocobitis rotundicaudata)found on both sides of the Taebaek Mountains that are geographically restricted to the Osip River(and several neighboring rivers,for *** and ***)on the eastern side of the mountain *** Osip River and its neighboring rivers also shared a rheophilic freshwater fish,Liobagrus mediadiposalis,with the Nakdong River on the western side of the mountain *** assessed historical biogeographic hypotheses on the presence of these rheophilic fishes,utilizing DNA sequence data from the mitochondrial cytochrome b *** of our divergence time estimation indicate that ichthyofaunal transfers into the Osip River(and several neighboring rivers in East Sea slope)have occurred from the Han(Yellow Sea slope)and Nakdong(Korea Strait slope)Rivers since the Late *** inferred divergence times for the ichthyofaunal transfer across the Taebaek Mountains were consistent with the timing of hypothesized multiple reactivations of the Osip River Fault(Late Pleistocene),suggesting that the Osip River Fault reactivations may have caused stream capture events,followed by ichthyofaunal transfer,not only between the Osip and Nakdong Rivers,but also between the Osip and Han Rivers.

The phylogeography of the Kaloula genus in East Asia is still poorly *** of the difficulties is the absence of fossils to corroborate molecular dating ***,we examined the mitochondrial structure of Kaloula *** East Asia and focused on the impact of glaciations on the northernmost species:Kaloula *** determined the phylogenetic relationships,molecular dating,and genetic connectivity assessments within the genus from 1211 bp of concatenated mitochondrial 12S and *** relaxed clock analyses reveal the emergence of Kaloula *** ancestor in East and Southeast Asia between the Eocene and Oligocene,c.38.47 Ma(24.69–53.65).The genetic diversification of lineages then increased on the East Asian Mainland during the Lower Miocene,c.20.10(8.73–30.65),most likely originating from the vicariance and radiation triggered by the orogeny of the Qinghai–Tibetan ***,the dispersal towards the North East Asian Mainland during the Upper Miocene drove the population diversification of *** c.9.01 Ma(3.66–15.29).Finally,the central mainland population became isolated following orogenesis events and diverged into *** during the Pliocene,c.3.06 Ma(0.02–10.90).The combination of population genetic and barrier analyses revealed a significant genetic isolation between populations of Kaloula *** with the massive Qinling–Daba Mountain chain located in south-central ***,we highlight a young divergence within the Eastern Mainland population of ***,possibly attributed to refugia in south eastern China from which populations later expanded.

现有的鸟类谱系生物地理学研究多偏重于欧洲地区,对欧亚大陆广布种类的遗传格局比较及形成机制研究涉及较少。本论文对喜鹊(Pica pica)、大山雀(Parus major)及沼泽山雀(Poecilepalustris)的欧亚大陆整体格局进行比较并基于线粒体及核基因分析,结果显示,三种鸟类均呈现出欧亚大陆北部种群与亚洲东部种群间的深度谱系分歧,分化时间在第三纪晚期/第四纪早期。种群动态重建结果显示,三个物种各支系内种群扩张时间在0.03-0.13MYA,与欧亚大陆北部分支相比,亚洲东部、南部的分支经历了更长的种群历史或更早的种群扩张。
