“…Statistical dating methods placed the divergence times in late Miocene to mid-Pliocene, roughly congruent with the most significant uplift of Mount Ailao in southwestern China. Zhang et al (2009) further suggest that pairs of divergent lineages coexist at two sampled localities, which implies secondary contact after initial divergence. They suggest that this secondary contact was caused by dispersing downslope and across the historical lowland barriers during Pleistocene glacial cooling.…”

“…Zhang et al (2009) recovered deep genetic structure within L. ailaonicum (known from southwestern China and northeastern Vietnam) that coincides with the major river valley systems in this region. They present further evidence to suggest that these clades diverged in allopatry.…”

“…They present further evidence to suggest that these clades diverged in allopatry. Zhang et al (2009) also noted that tight mtDNA haplotype clustering suggests historical population isolation, possibly due to specific habitat requirements. Leptobrachium ailaonicum breeds in cold, slow-flowing water found at midelevation montane streams.…”

“…Although it seems likely that historical records of Tylototriton verrucosus in Indochina refer to other species of Tylotriton, we treated it as present in Indochina until otherwise demonstrated (see Nussbaum et al, 1995). There is conflicting evidence as to whether Leptobrachium echinatum is a valid species or synonym of L. ailaonicum (Dubois and Ohler, 1998;Ho et al, 1999;Grosjean, 2001;Ohler et al, 2000;Rao and Wilkinson, 2008;Zheng et al, 2008;Zhang et al, 2009;Matsui et al, 2010). The phylogenetic evidence of Matsui et al (2010), and Rao and Wilkinson (2008) conflicts with that of Zheng et al (2008), as the former studies found the two to be distinct lineages, but the latter study found that recognizing L. echinatum renders L. ailaonicum nonmonophyletic.…”

“…Molecular studies in amphibians have commonly revealed strong phylogeographic structure and limited gene flow among populations, and have shown high levels of intraspecific mitochondrial divergence (Vieites et al, 2006). In recent decades, molecular markers have been used extensively to study phylogeographical patterns in different amphibians, and to group populations of species into distinct units for conservation in mainland China (Murphy et al, 2000;Zhang et al, 2008;Zhang et al, 2010). Conservation management authorities are increasingly recognising the importance of protecting genetic diversity within a species.…”

ABSTRACT. Amji's salamander (Hynobius amjiensis) is a critically endangered species (IUCN Red List), which is endemic to mainland China. In the present study, five haplotypes were genotyped for the mtDNA cyt b gene in 45 specimens from three populations. Relatively low levels of haplotype diversity (h = 0.524) and nucleotide diversity (π = 0.00532) were detected. Analyses of the phylogenic structure of H. amjiensis showed no evidence of major geographic partitions or substantial barriers to historical gene flow throughout the species' range. Two major phylogenetic haplotype groups were revealed, and were estimated to have diverged about 1.262 million years ago. Mismatch distribution analysis, neutrality tests, and Bayesian skyline plots revealed no evidence of dramatic changes in the effective population size. According to the SAMOVA and STRUCTURE analyses, H. amjiensis should be regarded as two different management units.

Aim With the late Cenozoic uplift of the Qinghai–Tibetan Plateau (QTP), drainage of the southeastern edge of the QTP changed significantly. However, the impact of this dramatic change on the geographical distribution and genetic diversity of endemic organisms is still poorly understood. Here, we examined the geographical patterns of genetic variation in the Yunnan small narrow‐mouthed frog, Glyphoglossus yunnanensis (Microhylidae), and two alternative hypotheses were tested: That is, the geographical distribution of genetic variation was determined by either the contemporary drainage basin or historical drainage basins. Location The Mountains of southwest China. Materials and methods Analyses were based on 417 specimens collected from across the distribution of the species. We reconstructed the genealogy (Bayesian and maximum parsimony methods) and assessed demographic history based on DNA sequencing data from mitochondrial and nuclear markers. We also mapped the genetic diversity and estimated the divergence times by a relaxed clock model. Results The species has maintained a relatively stable population size without recent population expansion. Four major maternal lineages were identified with good support, one representing a possible cryptic species and the other three showing further subdivision. The distribution of these deeply differentiated lineages/sublineages corresponded well to geographical regions. The secondary contact zones and phylogeographic breaks in distinct lineages of G. yunnanensis were almost concordant with those of Nanorana yunnanensis. Main conclusions Lineage division conformed to the hypothesis of drainage system evolution, that is, the phylogeographic pattern of G. yunnanensis was shaped by historical drainage patterns. Concordance in phylogeographic patterns may suggest a shared response to common hydrogeological history and also might indicate that there was more contribution of the drainage history than ecological or life‐history traits in structuring genetic variation between these two disparate codistributed taxa G. yunnanensis and N. yunnanensis.
