It is advocated that phylogeographic studies of plants in China should be directed to the closely related species or a monophyletic group in the coming years; and population genetic data based on direct sequencing multiple loci, especially those from nuclear genome and statistical tests should be widely adopted and enforced.

Evolutionary history of Purple cone spruce (Picea purpurea) in the Qinghai–Tibet Plateau: homoploid hybrid origin and Pleistocene expansion

Analyses of genetic divergence, Bayesian clustering and model comparison using approximate Bayesian computation of nuclear (nr) DNA variation all supported the hypothesis that P. purpurea originated by homoploid hybrid speciation from P. wilsonii and P. likiangensis, and suggested that following its origin, P. Purpurea underwent an expansion during/after the largest Pleistocene glaciation for the QTP.
Pliocene intraspecific divergence and Plio‐Pleistocene range expansions within Picea likiangensis (Lijiang spruce), a dominant forest tree of the Qinghai‐Tibet Plateau

The findings point to the importance of geological and climatic changes during the Pliocene and Pleistocene as causes of intraspecific diversification and range shifts of dominant tree species in the QTP biodiversity hot spot region.
Phylogeography of Potentilla fruticosa (Rosaceae) in the Qinghai-Tibetan Plateau revisited: a reappraisal and new insights

The results suggested that the range of the species radically expanded across the whole Plateau before the last glacial maximum and the south-eastern, western and central QTP regions had together provided important refugia during recent glacial stages, highlighting the importance of adequate sampling strategies in phylogeographical studies.
Multiple autopolyploidizations and range expansion of Allium przewalskianum Regel. (Alliaceae) in the Qinghai‐Tibetan Plateau

- 1 April 2010
It is found that the Allium przewalskianum diploid–tetraploid complex underwent an earlier range expansion around 5–150 thousand years ago (kya), after the largest glacial period (800–170 kya) in the QTP.

Population genetic evidence for speciation pattern and gene flow between Picea wilsonii, P. morrisonicola and P. neoveitchii.

- 1 December 2013
Modelling of population genetic data supported the hypothesis that P. morrisonicola derived from P. wilsonii within the more recent past, most probably indicating progenitor-derivative speciation with a distinct bottleneck, although further gene flow from the progenitors to the derivative continued.
Population genomic analysis reveals that homoploid hybrid speciation can be a lengthy process

- 22 November 2018
This study emphasizes the power of population genomic analysis combined with coalescent analysis for reconstructing the stages involved in the origin of a homoploid hybrid species over an extended period and shows that these stages can in some instances span a relatively long period of evolutionary time.
Distributional dynamics and interspecific gene flow in Picea likiangensis and P. wilsonii triggered by climate change on the Qinghai‐Tibet Plateau

The early increase in the distributions of these two species might have been triggered by enlargements of the available cold habitats brought about by QTP uplift and Pleistocene glaciations, but the distributional ranges decreased in response to climatic warming since the end of the largest glaciation.
