下福里虾虎鱼（Tridentiger bifasciatus）原产于西北太平洋沿岸的海洋、咸水和淡水水域。我们的研究利用线粒体 DNA [mtDNA 细胞色素 b (cyt b ) 基因和 d 环区域以及核 DNA [nuDNA 兰尼碱受体 3 (Ryr3) 基因的序列，检查了中国海域（包括黄海、东海和南海）的双条带鱼种群遗传结构、多样性和人口统计学。 mtDNA 数据集显示出显着的群体分化，但 nuDNA 数据集显示不存在遗传分化。这两个数据集之间的不一致是由种群混合、选择和不完整的谱系排序造成的。尽管mtDNA和nuDNA显示出不一致的种群结构，但这些遗传标记揭示了相同的种群历史：（1）种群在冰期期间退回到两个避难所；（2）最近种群数量下降。我们的研究表明，冰期之后，台湾海峡的重新洪水并没有影响南方谱系从南海向东海的迁移，并表明两个线粒体DNA谱系在冰期期间向南迁移之前已经发生了分歧。这些结果为保护遗传学的进一步研究提供了重要资源。
The shimofuri goby ( Tridentiger bifasciatus ) is native to marine, brackish, and fresh waters along the coasts of the northwest Pacific. Our study examined the population genetic structure, diversity, and demography of T. bifasciatus in the China Seas, including the Yellow Sea, East China Sea, and South China Sea, using the sequences of mitochondrial DNA [mtDNA cytochrome b (cyt b ) gene and d-loop region and nuclear DNA [nuDNA ryanodine receptor 3 (Ryr3) gene. The mtDNA dataset revealed a significant population differentiation, but the nuDNA dataset displayed the absence of genetic differentiation. The discordance between these two datasets was accounted for by population admixture, selection, and incomplete lineage sorting. Although the mtDNA and nuDNA displayed a discordant population structure, these genetic markers revealed the same population history: (1) the populations retreated into two refugia during glaciations and (2) the populations declined recently. Our study revealed that after glaciations, the re-flooding in Taiwan Strait did not shape the migrations of the southern lineage from the South China Sea to the East China Sea, and displayed that two mtDNA lineages have diverged before they migrated southward during glaciations. These results offer important resources for the further study of conservation genetics.
