| 英文摘要 | The tibetan gazelle (procapra picticaudata) is a threatened species and distributed on the qinghai-tibet plateau of china (qinghai province, tibet autonomous region and the adjacent gansu province, sichuan province, and xinjiang uigur autonomous region). small peripheral populations of tibetan gazelle were once found in northern sikkim and ladakh, but now these are close to extinction. to describe the evolutionary history and to assess the genetic diversity within this monotypic species and population structure among different geographic locations in china, we sequenced mitochondrial dna from the control region (cr) and cytochrome (cyt) b gene for 46 individuals from 12 geographic localities in qinghai, tibet, xinjiang, gansu, and sichuan. a total of 25 cr haplotypes and 16 cyt b haplotypes were identified from these gazelle samples. cr haplotype diversity (0.98 +/- 0.01) and nucleotide diversity (0.08 +/- 0.009) were both high. phylogenetic trees indicate that the tibetan gazelle in china can be divided into three main clades: tibet, sichuan (sch) and qinghai-arjin shan-kekexili (qh-arj-kkxl). analysis of molecular variance (amova) and network analysis consistently support this geographic structure in both datasets. significant differentiation between populations argues for the presence of management units (mus). such differentiation may reflect a geographic separation resulting from the uplift of the qinghai-tibet plateau during the late pliocene and pleistocene. mismatch distribution analysis implies that tibetan gazelle has undergone complex population changes. we suggest that the present population structure has resulted from habitat fragmentation during the recent glacial period on the qinghai-tibet plateau and population expansion from glacial refugia after the glacial period. it is likely that the present populations of tibetan gazelle exhibit a pattern reminiscent of several bottlenecks and expansions in the recent past.
