英文摘要the qinghai-tibetan plateau (qtp) uplift had a decisive effect on climatic and eco-environmental evolution in east asia during the quaternary. in the current study phylogeographic structure and diversification history of spiraea alpine across the qtp were investigated for the first time based on nuclear internal transcribed spacer. the nuclear internal transcribed spacers (its1a-its4) were generated for a total of 284 individuals distributed within 31 natural populations. a clear phylogeographic structure was found for s. alpina. the results showed that this species colonized in three different glacial refugia during the quaternary extensive glaciation and expanded during the interglacial period. analysis of molecular variance (amova) showed 74.13% genetic diversity among populations and 25.87% genetic variation within populations with distinct phylogeographic structure (f-et = 0.741*). the estimated divergence time revealed that the main lineages of s. alpine diversified during the quaternary 1.2-0.6 million years ago. the study concluded that severe climatic oscillations during quaternary and the uplift of qtp had a profound effect on intraspecific divergence of s. alpine.
