本研究利用一个线粒体基因和一个核基因以及两个形态学特征对中华长翅天牛的地理分布进行了研究。系统发育和种群遗传学分析的序列揭示了两个不同的地理谱系从中国东海和南海，这是证实了形态数据。这两个谱系的分离归因于更新世冰期台湾海峡的暴露和随后的台湾与大陆的连接，从而在东海和南海的种群之间引入了基因流动的生态屏障。这两个支系的分布现在在东海重叠，这种次级接触归因于台湾海峡在间冰期再洪泛后沿两个主流沿着偏北迁移。总之，这项研究加强了“vicariance，然后二次接触”的重要性，由于晚上新世和更新世海平面的变化，海洋物种的地理分布。特别是，它证实了台湾海峡更新世海平面变化的重要性，中国近海物种的地理。(C)2015爱思唯尔公司All rights reserved.
This study assesses the phylogeography of the Chinese four-eyed sleeper (Bostrychus sinensis) with one mitochondrial and one nuclear genes and two morphological characters. Phylogenetic and population genetic analyses of the sequences reveals two phylogeographic lineages from the East and South China Seas, which are corroborated by the morphological data. The vicariance of the two lineages is attributed to the Pleistocene Ice Age exposure of the Taiwan Strait and consequent connection of Taiwan to the mainland, which thereby introduced an ecological barrier to gene flow between populations in the East and South China Seas. The distributions of the two lineages now overlap in the East China Sea and this secondary contact is attributed to biased northward migration along the two main currents of the Taiwan Strait following its interglacial re-flooding. In conclusion, this study reinforces the importance of "vicariance, then secondary contact" due to Late Pliocene and Pleistocene sea-level changes to the phylogeography of marine species. Specifically, it corroborates the importance of Pleistocene sea-level changes in the Taiwan Strait to the phylogeography of Chinese inshore species. (C) 2015 Elsevier Inc. All rights reserved.
