“…Studies of Quaternary glacial histories around this area gave controversial results. One class of opinion believed there was limited snowline decrease, less than 300 m, due to the extreme aridity of this area (Shi, 2002), whereas the other class suggests an ice sheet covering the entire plateau and its flanks during the LGM (Kuhle, 1998). Recently, Owen et al (2002) reviewed current knowledge about the timing of the late Quaternary glaciation in seven regions of the Himalayas, and concluded that glaciers had advanced only several tens of kilometres from the present ice front during the LGM.…”

“…All samples are located above 5000 m over sea level. Studies of Quaternary glacial histories around this area have given controversial results: some believe there was limited ice cover (Schäfer et al, 2002;Shi, 2002), whereas others suggest an ice sheet covering the entire plateau and its flanks during the global Late Glacial Maximum (LGM) (Kuhle, 1998).…”

“…In addition, some high Mountains (e.g., Taibai mountain) greater than 3,000 m above sea level (a.s.l.) in the QM region were likely covered by ice caps during the Pleistocene ice ages (Rost 1994;Shi 2002Shi , 2007Li et al 2004). A complex tectonic history and quaternary glaciations may have contributed to genetic-diversity patterns and evolutionary process of organisms in this region.…”

Phylogeographic Patterns of mtDNA Variation Revealed Multiple Glacial Refugia for the Frog Species Feirana taihangnica Endemic to the Qinling Mountains

Diversification patterns and demography of montane species are affected by Pleistocene climate fluctuations. Empirical cases from the Qinling Mountains (QM) region, which is a major biogeographic divider of East Asia, are few. We used DNA sequence data of the complete mitochondrial ND2 gene to detect effects of the Pleistocene glaciations on phylogeographic profiles of a frog species, Feirana taihangnica, which is endemic to the QM. Four distinct lineages consisting of seven sublineages were revealed. The strongest signal of biogeographical structure (F ct = 0.971, P \ 0.01) was found when populations were grouped according to these seven sublineages. One narrow secondary contact zone was detected in the middle QM between the lineage from middle QM and the lineage from eastern QM. Coalescent simulations indicated that this species colonized the QM region by a stepping-stone model. Divergences among lineages had likely been influenced by the uplift of the Tibetan Plateau during the late Miocene-tolate Pleistocene, as well as by the Pleistocene climatic cycles. Coalescent simulations also suggested that F. taihangnica populations have persisted through the Pleistocene glacial periods in multiple refugia across the QM region. Demographic analyses indicated that all lineages, except the lineage in the Funiu Mountains, have been experienced postglacial expansion of population size and distribution range. In conclusion, Pleistocene climate fluctuations and tectonic changes during the late Miocene-late Pleistocene have profoundly influenced the phylogeography and historical demography of F. taihangnica.

“…However, there is an ongoing debate on the timing of Quaternary glaciations and their relationship to changes of precipitation and temperature (e.g. Shi, 2002;Zhou et al, 2002;Lehmkuhl and Owen, 2005;Owen et al, 2009;Zhou et al, 2010;Ou et al, 2012), which is partly due to a lack of suitable datable materials (for radiocarbon and terrestrial cosmogenic nuclides exposure-age dating). Although the timing and succession of glaciations are ill-defined as a consequence of poor chronological control in most parts of the Tibetan Plateau, it was previously concluded that glacial advances there were mainly influenced by precipitation, controlled by the South Asian monsoon (e.g.…”

Late Quaternary paleoclimatic and geomorphological evolution at the interface between the Menyuan basin and the Qilian Mountains, northeastern Tibetan Plateau

The Tibetan Plateau is regarded as an amplifier and driver of environmental change in adjacent regions because of its extent and high altitude. However, reliable age control for paleoenvironmental information on the plateau is limited. OSL appears to be a valid method to constrain the age of deposits of glacial and fluvial origin, soils and periglacial structures in the Menyuan basin on the northeastern Tibetan Plateau. Dating results show glaciers advanced extensively to the foot of the Qilian mountains at~21 ka, in agreement with the timing of the global Last Glacial Maximum (LGM) recorded in Northern Hemisphere ice cores. Comparison with results from the eastern Tibetan Plateau suggests that the factor controlling glacial advance in both regions was decreased temperature, not monsoon-related precipitation increase. The areas of the Menyuan basin occupied by glacio-fluvial deposits experienced continuous permafrost during the LGM, indicated by large cryoturbation features, interpreted to indicate that the mean annual temperature was ≥7°C lower than at present. Glacio-fluvial systems in the Menyuan basin aggraded and terraces formed during cold periods (penultimate glaciation, LGM, and possibly the Younger Dryas) as a response to increased glacial sediment production and meltwater runoff then.
