更新世气候波动对东亚秦岭-大巴山种内多样性的影响仍然缺乏研究。我们检验了该地区最后一次冰川盛期(LGM)期间关于避难所的假设，方法是研究膨胀的喷口蛙(四角蛙；无尾两栖动物，无尾两栖动物)的系统地理。我们从34个种群中获得了224个个体的完整线粒体ND2基因序列，用于系统地理分析。此外，我们还获得了68个方斑扇贝、1个康县扇贝和3个太行山扇贝的核酪氨酸酶基因序列，以检测其中的线粒体渗透。基于所有基因的系统发育分析表明，它们之间没有相互渗透。基于ND2数据集的系统发育分析表明，四翼鸟由被深谷隔开的6个谱系组成，唯一的例外是主秦岭和米仓-西秦岭谱系在分布上重叠。对种群结构的分析表明，谱系之间的基因流动受到限制。联合模拟和发散测年结果表明，上新世青藏高原的剧烈隆升可能与四分星内部的基本多样性有关。合并模拟表明，武陵、大坝和西秦岭-米仓-龙门山是末次盛冰期象限管藻的避难所。人口统计分析表明，大巴族在大冰期前种群规模有所增加，但主要秦岭和米仓-西秦岭宗族在大冰盛期后种群规模和分布范围扩大，其他宗族的种群规模几乎保持稳定或略有缓慢的下降。在末次盛冰期，秦岭-大巴山曾接待过三次象限锥虫的避难所。起源于大巴山的种群在大冰盖年后殖民了主要的秦岭山脉。米仓-西秦岭和主要秦岭谱系近期的急剧扩张可能对它们今天的二次接触起到了作用。
The influence of Pleistocene climatic fluctuations on intraspecific diversification in the Qinling–Daba Mountains of East Asia remains poorly investigated. We tested hypotheses concerning refugia during the last glacial maximum (LGM) in this region by examining the phylogeography of the swelled vent frog (Feirana quadranus; Dicroglossidae, Anura, Amphibia). We obtained complete mitochondrial ND2 gene sequences of 224 individuals from 34 populations of Feirana quadranus for phylogeographic analyses. Additionally, we obtained nuclear tyrosinase gene sequences of 68 F. quadranus, one F. kangxianensis and three F. taihangnica samples to test for mitochondrial introgression among them. Phylogenetic analyses based on all genes revealed no introgression among them. Phylogenetic analyses based on ND2 datasets revealed that F. quadranus was comprised of six lineages which were separated by deep valleys; the sole exception is that the Main Qinling and Micang–Western Qinling lineages overlap in distribution. Analyses of population structure indicated restricted gene flow among lineages. Coalescent simulations and divergence dating indicated that the basal diversification within F. quadranus may be associated with the dramatic uplifts of the Tibetan Plateau during the Pliocene. Coalescent simulations indicated that Wuling, Daba, and Western Qinling–Micang–Longmen Mountains were refugia for F. quadranus during the LGM. Demographic analyses indicated that the Daba lineage experienced population size increase prior to the LGM but the Main Qinling and the Micang–Western Qinling lineages expanded in population size and range after the LGM, and the other lineages almost have stable population size or slight slow population size decline. The Qinling–Daba Mountains hosted three refugia for F. quadranus during the LGM. Populations that originated in the Daba Mountains colonized the Main Qinling Mountains after the LGM. Recent sharp expansion of the Micang–Western Qinling and Main Qinling lineages probably contribute to their present-day secondary contact.
