通过对中国大蹄蝠线粒体DNA控制区序列变异的分析,探讨了中国大蹄蝠遗传结构的地理格局。分子变异分析表明,在H. armiger。邻接树、TCS构建的单倍型网络和多维标度图均显示了5个地区间的显著地理分化。在H. armiger可能是扩散能力差、局部适应性差或明显的雌性亲蜜的结果。高黎贡山脉和琼州海峡分隔的3个地区之间缺乏遗传结构,可能是由于谱系分类不完整。我们估计了H. armiger种群表明相对较新的分裂。遗传多样性最高的滇南种群和遗传多样性最低的海南种群应同等优先保护。虽然H.虽然已证明armiger携带与人类疾病有关的病毒,但我们几乎没有发现种群混合的证据。因此,我们建议尽量减少对蝙蝠栖息洞穴的干扰,以减少病毒传播的潜在风险。
The geographical patterns of the genetic structure of Hipposideros armiger in China were assessed by analyzing sequence variation in the mitochondrial DNA control region. Analysis of molecular variance revealed a very strong genetic structure among 5 regions in H. armiger. A neighbor-joining tree, haplotype network construction by TCS and multidimensional scaling plots all showed significant geographic differentiation among 5 regions. The high genetic structure detected in H. armiger could be a consequence of poor dispersal ability, local adaptation, or marked female philopatry. The lack of genetic structure among 3 regions separated by the Gaoligong Range and the Qiongzhou Strait could be due to incomplete lineage sorting. Our estimated times of divergence for H. armiger populations suggested a relatively recent split. The S Yunnan population with the highest genetic diversity and the Hainan population with the lowest genetic diversity should be equally given priority for conservation. Although H. armiger has been shown to carry viruses implicated in human disease, we find little evidence for population mixing. We thus suggest minimizing disturbance to bats' roosting caves for minimizing the potential risk of virus transmission.
