| Abstract | Using phylogenetic and population genetic approaches, the present study reports the phylogeographic structure of the sharp-snouted pitviper (Deinagkistrodon acutus), a threatened snake species with commercial and medicinal importance in China. The entire mitochondrial ND2 gene (NADH dehydrogenase subunit 2) sequences of 86 individuals of D. acutus from 14 localities across its range in China were determined. Based on the results of phylogenetic analyses, distribution of diagnostic sites, haplotype network, and AMOVA hierarchical analysis, an cast-west division of the whole D. acutus population could be observed. Geographically, a line formed by a lake, river, and mountain chain (the Poyang Lake, Gan River to the southern end of the Wuyi Mountains), results in vicariance and approximately vertically splits the range into two and the whole population into two main lineages (western and eastern). The bifurcating tree suggested generally west to east dispersal trend. The data fit the isolation by distance (IBD) model well. Star-like clusters in haplotype network, significantly negative values of Fs statistics, and unimodal mismatch distributions all suggest recent demographic expansions in four areas. The results show that isolation, dispersal, bottleneck, and expansion jointly constitute the history of D. acutus. In a haplotype network, the excessive predominance of central haplotypes, few medium-frequency haplotypes, predominance (73.1 %) of the singletons among the derived haplotypes, most of which are connected to the central haplotype by only one mutational step, unsymmetrical campanulate unimodal curve of mismatch distributions and leftwards shift of the peaks, all suggest that the whole D. acutus population is a young population with low genetic diversity. Based on the data, the first priority for conservation action should be given to the Huangshan unit. (c) 2007 Elsevier Inc.
