“…Given that the Tarim Basin probably did not have Quaternary glaciers [27][28][29][30][31][32], why did only the southwestern Tarim Basin contain refugia during glacial events, if the northeast was also not glaciated? The Tarim Basin is located north of the Qinghai-Tibetan Plateau.…”

Orogenesis of the Qinghai-Tibetan Plateau, which occurred in a stepwise manner, contributed to the extreme aridity of the Tarim Basin, resulting in vulnerable and unstable ecosystems. Quaternary climatic oscillations may have affected the ecosystems and, consequently, the distributions and genetic structuring of the Tarim Basin's biota. We used nucleotide sequence data from 2 mitochondrial (mt) DNA genes (Cyt b and the D-loop) to test hypotheses associated with the matrilineal and demographical histories of the Tarim Basin's endemic Yarkand hare (Lepus yarkandensis). Range-wide sampling involving 20 populations and 224 individuals detected 126 haplotypes that clustered into 5 major lineages in both the phylogenetic tree and median-joining network. Populations from the northern and eastern Tarim Basin shared a similar history, as did those from the western and southern regions. Demographical analysis and genetic diversity estimations suggested that the western and southern regions might have served as glacial refugia for the Yarkand hare during Quaternary climatic oscillations. The distribution of the Yarkand hare, especially in the northern and eastern parts, probably represented 3 postglacial colonization events, dated to 0.21, 0.090 and 0.054 MYA, which corresponded to known interglacial periods. Given the relatively complete geographic isolation between the eastern and southern populations, the Yarkand hare likely dispersed during postglacial periods from the southwest to the north, and then onward to the east. The absence of water likely forced the species into refugia, and this differed from other Pleistocene biogeographical drivers. The demographical and historical patterns have important implications for conservation. Chinese Sci Bull, 2011, 56: 1370−1382, doi: 10.1007 Pleistocene climatic changes imposed significant range shifts on many Palearctic biota, and contributed to their demographic history and genetic diversity [1]. Many temperate species existed only in refugia at times of glacial maxima, and recolonized or expanded into newly available habitats during interglacial periods [2,3].

“…Being extremely arid, the basin's ecosystem is vulnerable and unstable [23][24][25][26]. During the Quaternary, montane glaciers surrounded the Tarim Basin, but these were absent within the Tarim Basin itself [27][28][29][30][31][32].…”

“…Therefore, it can potentially date ages of the glacial sediments and augment conventional maping and relative dating in Quaternary glaciation research. In the past several years, many researchers have applied this technique in determining the timing of Quaternary glaciations with considerable successes [7][8][9][10][11][12][13].…”

The Pochengzi Glaciation is a typical glaciation in Quaternary in the Tianshan Mountains. The glacial landforms comprise several integrated end moraines, like a fan spreading from the north to the south at the mouth of the Muzhaerte River valley and on the piedmont on the southeastern slope of the Tumur Peak, the largest center of modern glaciation in the Tianshan Mountains. The landforms recorded a complex history of the ancient glacier change and contained considerable information of the glacial landscape evolution, and dating these landforms helps us understand the temporal and spatial shifts of the past cryosphere in this valley and reconstruct the paleoenvironment in this region. Electron spin resonance (ESR) dating of the glacial tills in the upper stratum from a well-exposed section, end moraines, and associated outwashes was carried out using Ge centers in quartz grains, which are sensitive to the sunlight and grinding. The results could be divided into three clusters, 13. 6-25.3, 39.5-40.4 and 64.2-71.7 ka. Based on the principle of geomorphology and stratigraphy and the available paleoenvironmental data from northwestern China, the end moraines were determined to deposit in the Last Glaciation. The landforms and the three clusters of ages demonstrate that at least three large glacial advances occurred during the Pochengzi Glaciation, which are corresponding to marine oxygen isotope stage 4 (MIS4), MIS3b and MIS2. The landforms also indicate that the glaciers were compound valley glacier in MIS2 and MIS3b and piedmont glacier in MIS4, and the ancient Muzhaerte glacier were 94, 95 and 99 km at their maximum extensions in these three glacial advances.

“…To the west of the Helan Mountain, three glaciations assigned as the Zhonglianggan Glaciation [31], Penultimate Glaciation and Last Glaciation occurred in Lenglongling of the Qilian Mountain (4843 m) and around Bogeda peak (5545 m) in the Tianshan Mountains during the Quaternary epoch. Yi and Zhou [32][33][34][35] first reported the older glaciation in the headwater area of the Urumqi River in the Tianshan Mountains and the Bailang River valley in the Qilian Mountain respectively, and its age is 520-405 ka. Recently, Zhao found the evidence of this glacial advance in Tuomuer peak and Ateaoyinake River drainage area of the southern slopes of western Tianshan Mountains (425.3 and 453.0 ka).…”
