title: [A long distance colonization event of Chinese endemic bat Myotis davidii].
abstract: In order to reveal the population phylogenetic relationships and colonization history of Chinese endemic bat species Myotis davidii, a total of 126 samples from 14 populations in nationwide were collected in 2001-2009, taking the mitochondrial control region as the molecular marker. Based on the TCS network diagram of the mitochondrial DNA control region sequences, the 14 geographical populations were divided into three geographical regions, i.e., mid-east plain region, southwest plateau region, and south hills region. In the 53 haplotypes, the No. 14 in Zhejiang Province, No. 47 in Guizhou Province, and No. 50 in Guangdong Province were the ancestors in the three regions, respectively. Based on Geodis analysis, mismatch distribution analysis, and neutrality test, the population expansion events were found in mid-eastern plain region (76.12 and 79.17 ka BP) and southwest plateau (69.12 ka BP). In 61.24 ka BP, a long distance migration event originated from the southwest plateau region to the mid-east plain region occurred. The evidences of molecular biology, bionics, anatomy, and aerodynamics all revealed the long-distance migration capability of M. davidii.
