“…A Pleistocene divergence time for L. phoenicea and L. ripponi roughly coincides with those for some montane forest birds in the region [80] but is later than others [74]. The Mekong-Salween Divide has been proposed as a biogeographic barrier for the region [98,99]. The divide between the parapatric distributions of L. phoenicea and L. ripponi appears to be west of the traditional MekongSalween Divide approximately at the Myitnge River and Myanmar's Eastern highlands [1] but additional data on the distribution of these taxa are needed.…”

A multilocus molecular phylogeny for the avian genus Liocichla (Passeriformes: Leiothrichidae: Liocichla)

Background: Historically the babblers have been assigned to the family Timaliidae but several recent studies have attempted to rest the taxonomy of this diverse passerine assemblage on a more firm evolutionary footing. The result has been a major rearrangement of the group. A well-supported and comprehensive phylogeny for this widespread avian group is an important part of testing evolutionary and biogeographic hypotheses, especially in Asia where the babblers are a key component of many forest ecosystems. However, the genus Liocichla is poorly represented in these prior studies of babbler systematics. Methods:We used a multilocus molecular genetic approach to generate a phylogenetic hypothesis for all five currently recognized species in the avian genus Liocichla. Multilocus DNA sequence data was used to construct individual gene trees using maximum likelihood and species trees were estimated from gene trees using Bayesian analyses. Divergence dates were obtained using a molecular clock approach. Conclusions:This study supports an origin of the Liocichla occurring sometime prior to the Miocene-Pliocene boundary, a period of significant climatic upheaval in Asia. The biogeographical patterns within the Liocichla mirror those of other birds in the region and allude to common geological and climatic drivers of avian diversification in Asia.

“…4, inset). Extensive migrations up and down mountain slopes and river valleys particularly in the Three River gorges, driven by climatic effects of glacialinterglacial cycles during the Quaternary (Li et al 2011), may have been involved in the diversification of C. lanuginosus which would have created opportunities for secondary contacts, even of populations that have diverged a long time ago (e.g. subclades II and III) and now occupy the same localities.…”

“…Climatic fluctuations during the Quaternary (e.g. Wang et al 2010;Xu et al 2010) can add to the diversity by expanding and contracting distribution ranges, local adaptation, allowing secondary contacts and creating, over time, biodiversity hot spots such as the Himalayas and Hengduan Mountains (Myers et al 2000;Liu and Tian 2007;Li et al 2011).…”

Corallodiscus lanuginosus is distributed 12,000 km across its northeast-southwest boundaries, showing its highest morphological diversity in the Hengduan Mountains, Southwest China. We investigated the mechanisms behind the high diversity in this species. We acquired ITS sequence data across the distribution range of the genus, reconstructed dated phylogenies, projected the resulting clades onto geographic maps and linked the results with inferred ploidy levels of the populations. We found strong geographic patterns for the ITS clades but with extensively overlapping ranges, particularly in the Hengduan Mountains area. We deduced an origin of C. lanuginosus in the mid-Oligocene. We used the presence of ITS polymorphisms to infer a high level of hybridization events mainly in areas of clade overlap, where we also inferred repeated tetraploidization events to have taken place. Pre-and post-Quaternary climate oscillation-driven expansions and contractions of distribution ranges have allowed secondary contacts, hybridization and introgression that shaped the current patchy distribution of morphological diversity in the species. Polyploidization as a reinforcing genetic barrier added to the genetic diversity in space and time particularly in the Hengduan Mountains.

“…Then, as no fossil records are available to calibrate intergenic spacers substitution rate for genus Rosa, branch lengths of the clock-constrained ML tree were transformed into absolute time by assuming the substitution rates of these spacers to be (1.2-1.7) 9 10 -9 substitutions per site per year (s/s/y) (Graur and Li 2000). Of course, this is merely a rough estimation for the substitution rate of non-coding chloroplast regions of seed plants, which can be used to estimate the divergence time of taxa without fossil records in the same studied area (e.g., Sinopodophyllum hexandrum, Li et al 2011).…”

Phylogeography of Rosa soulieana (Rosaceae) in the Hengduan Mountains: refugia and ‘melting’ pots in the Quaternary climate oscillations

The Hengduan Mountains is the core of the Sino-Himalayan Floristic Region. Different views have been postulated from phylogeographic studies in understanding the historical biological events shaping presentday distributions and species diversities in this area. We analyzed the phylogeography of Rosa soulieana, a widely distributed rose species in dry and semi-dry valleys of the Hengduan Mountains of southwestern China using two cpDNA intergenic spacers. 9 cpDNA haplotypes were confirmed in 650 individuals from 39 populations, with the most dominant one existing in 36 populations. The relationship among the cpDNA haplotypes did not reflect the morphology-based intra-specific taxonomy of different varieties. There was very low cpDNA genetic diversity and relatively high population differentiation combined with lack of phylogeographic structure. The populations from Northwestern Yunnan, Southeastern Tibet and upper Yalongjiang River embraced most of the species genetic diversity, but with contribution of different historical effects. Northwestern Yunnan and upper Yalongjiang River appear to be the species refugia and centers of adaptive diversification, while Southeastern Tibet rather represents the species 'melting pot' in the Quaternary climate oscillations.
