“…The high mountains (e.g., Hengduan, Wumeng, Cang and Ailao, Gaoligong Mountains, etc. ), the gorges, and complex paleodrainage basins have served as effective barriers to dispersal and promoted genetic diversification of organisms, which has been reported in multiple phylogeographic studies (He and Jiang 2014;Yue et al 2012;Zhang et al 2010). Furthermore, the suitable habitats in these regions for Q. glauca are limited and scattered because of the extreme climatic variation across short distances.…”

Historical geoclimatic events have shaped the distribution patterns and intraspecific divergence of plants. Numerous phylogeographical studies in China have focused on the Qinghai-Tibetan Plateau and surrounding areas due to the complex topography and high species diversity, but the impact of Neogene events and Quaternary climatic change on the flora of subtropical China remains poorly understood. Quercus glauca, a widespread tree of East Asian subtropical evergreen forests, has rich fossil records dating back to the Neogene, and it provides a good model to explore the impact of paleogeoclimate changes on East Asian subtropical forests. We used three chloroplast DNA (cpDNA) intergenic spacer regions and ecological niche modeling (ENM) to analyze the divergence pattern and demographic history of Q. glauca in China and Japan. A total of 33 haplotypes were detected. The phylogenetic analysis revealed two major haplotype lineages (Southwest China vs. Southeast China and East China Sea). The limited dispersal ability of seeds and complex topography resulted in the high total, inter-and intrapopulation haplotype diversity. The fossil-constrained BEAST analysis revealed a lineage diversification in the late Miocene-Pliocene. The formation of complex topography changes since Miocene in east Himalaya and adjacent area might be the key factor that triggered the intraspecific divergence of Q. glauca. Haplotype spatial distribution, ENM, mismatch distribution, and neutrality tests suggest that Q. glauca in Southeast China experiences expansion, and the current distribution in region III might be shaped by southward expansion from regions I and II after last glacial maximum (LGM). Regions I and II were the potential glacial refugia of Q. glauca.

“…Climate and geography are strong drivers of genetic diversity (He and Jiang 2014;Mosca et al 2012). The relative roles that climate and geography play in driving genetic patterns have important implications for species diversification, conservation, and biogeography, among other phenomena (Fouquet et al 2010;Hewitt 1996;Shih et al 2006b).…”

“…During the Pleistocene, climatic fluctuations and periodic uplifting of the Qinghai-Tibetan Plateau had important effects on biodiversity and changes in the 6 geographic distribution of mammals in southwest China (He and Jiang 2014). For example, it has been suggested that the LIG (Last Interglacial Maximum) was an 8 unfavorable period for mole shrews (Anourosorex squamipes) because of increased seasonality in temperature extremes.…”

Snub-nosed monkeys (genus Rhinopithecus) are a group of endangered colobines 2 endemic to South Asia. Here, we re-sequenced the whole genomes of 38 snub-nosed monkeys representing four species within this genus. By conducting population 4 genomic analyses, we observed an similar load of deleterious variation in snub-nosed monkeys living in both smaller and larger populations and found that genomic 6 diversity was lower than that reported in other primates. Reconstruction of Rhinopithecus evolutionary history suggested that episodes of climatic variation over 8 the past 2 million years, associated with glacial advances and retreats and population isolation, have shaped snub-nosed monkey demography and evolution. We further 10 identified several hypoxia-related genes under selection in R. bieti (black snub-nosed monkey), a species that exploits habitats higher than any other nonhuman primate. 12These results provide the first detailed and comprehensive genomic insights into genetic diversity, demography, genetic burden and adaptation in this radiation of 14 endangered primates. 16

“…The MSC, also known as the Hengduan Mountains, and the adjacent areas have complex topographies that support extremely high biodiversity, and have been recognized as biodiversity hotspots (He and Jiang, 2014). One plausible explanation for the great biodiversity is known as the 'refugia hypothesis' (Zhang, 2002).…”

“…In the MSC, the complex topography provides ecologically diverse habitats, so that organisms could find suitable habitats by moving up and down the mountains during periods of unfavorable climate conditions, with lower extinction risks. An alternative hypothesis suggested that the complex topography created fragmented habitats in the mountains, so that populations of a species were isolated, resulting in allopatric diversification (He and Jiang, 2014).…”

The mountains of southwest China (MSC) harbor extremely high species diversity; however, the mechanism behind this diversity is unknown. We investigated to what degree the topography and climate change shaped the genetic diversity and diversification in these mountains, and we also sought to identify the locations of microrefugia areas in these mountains. For these purposes, we sampled extensively to estimate the intraspecific phylogenetic pattern of the Chinese mole shrew (Anourosorex squamipes) in southwest China throughout its range of distribution. Two mitochondrial genes, namely, cytochrome b (CYT B) and NADH dehydrogenase subunit 2 (ND2), from 383 archived specimens from 43 localities were determined for phylogeographic and demographic analyses. We used the continuous-diffusion phylogeographic model, extensive Bayesian skyline plot species distribution modeling (SDM) and approximate Bayesian computation (ABC) to explore the changes in population size and distribution through time of the species. Two phylogenetic clades were identified, and significantly higher genetic diversity was preserved in the southern subregion of the mountains. The results of the SDM, continuous-diffusion phylogeographic model, extensive Bayesian skyline plot and ABC analyses were congruent and supported that the Last Interglacial Maximum (LIG) was an unfavorable period for the mole shrews because of a high degree of seasonality; A. squamipes survived in isolated interglacial refugia mainly located in the southern subregion during the LIG and rapidly expanded during the last glacial period. These results furnished the first evidence for major Pleistocene interglacial refugia and a latitudinal effect in southwest China, and the results shedding light on the higher level of species richness in the southern subregion.
