Evolution of Asian monsoons and phased uplift of the Himalaya–Tibetan plateau since Late Miocene times
TLDR
The results of a numerical climate-model experiment support the argument that the stages in evolution of Asian monsoons are linked to phases of Himalaya–Tibetan plateau uplift and to Northern Hemisphere glaciation.Abstract:
The climates of Asia are affected significantly by the extent and height of the Himalayan mountains and the Tibetan plateau1,2,3,4 Uplift of this region began about 50 Myr ago, and further significant increases in altitude of the Tibetan plateau are thought to have occurred about 10–8 Myr ago4,5, or more recently However, the climatic consequences of this uplift remain unclear Here we use records of aeolian sediments from China6,7 and marine sediments from the Indian8,9,10 and North Pacific oceans11 to identify three stages of evolution of Asian climates: first, enhanced aridity in the Asian interior and onset of the Indian and east Asian monsoons, about 9–8 Myr ago; next, continued intensification of the east Asian summer and winter monsoons, together with increased dust transport to the North Pacific Ocean11, about 36–26 Myr ago; and last, increased variability and possible weakening of the Indian and east Asian summer monsoons and continued strengthening of the east Asian winter monsoon since about 26 Myr ago The results of a numerical climate-model experiment, using idealized stepwise increases of mountain–plateau elevation, support the argument that the stages in evolution of Asian monsoons are linked to phases of Himalaya–Tibetan plateau uplift and to Northern Hemisphere glaciationread more

Age constraints on the India–Asia collision derived from secondary remanences of Tethyan Himalayan sediments from the Tingri area
TL;DR: In this article, the authors report paleomagnetic results from the Zhepure Shan Formation and the Youxia Formation of the Tingri section (28°42′N/86°43′E) and the Longjiang section in southern Tibet.

Iron oxide characteristics of the Chinese loess-red clay sequences and their implications for the evolution of the East Asian summer monsoon since the Late Oligocene
TL;DR: In this paper, the composition and relative abundance of pedogenic iron oxides of two eolian sequences from the Lingtai section and the Zhuanglang drill core were investigated using rock magnetic, optical spectroscopy, and geochemical analyses.
Altitudinal variation of skull size in daurian pika (ochotona daurica pallas, 1868)
J. Liao,Zhibin Zhang,N. Liu +2 more
TL;DR: This study tested the skull size of Daurian pika and showed that skull size is negatively correlated with altitude, confirming that Bergmann’s rule is not universally valid on interpreting for animal body size cline.

Clay mineralogy indicates a mildly warm and humid living environment for the Miocene hominoid from the Zhaotong Basin, Yunnan, China.
Chunxia Zhang,Zhengtang Guo,Zhengtang Guo,Chenglong Deng,Xueping Ji,Haibin Wu,Greig A. Paterson,Lin Chang,Qin Li,Bailing Wu,Rixiang Zhu +10 more
TL;DR: Comparing mid to late Miocene records from hominoid sites in Yunnan, Siwalik in Pakistan, and tropical Africa it is found that ecological shifts from forest to grassland in SiwAlik are much later than in tropical Africa, consistent with the disappearance of hominoids.

Landscape Features and Climatic Forces Shape the Genetic Structure and Evolutionary History of an Oak Species (Quercus chenii) in East China.
TL;DR: It is concluded that mountainous areas with higher climatic stability are more likely to be glacial refugia that preserved higher phylogenetic diversity, while plains and basins may have acted as dispersal corridors for the post-glacial south-to-north migration.

Global vegetation change through the Miocene/Pliocene boundary
Thure E. Cerling,John Harris,Bruce J. MacFadden,Meave G. Leakey,Jay Quade,Véra Eisenmann,James R. Ehleringer +6 more
TL;DR: For example, this paper found that between 8 and 6 million years ago, there was a global increase in the biomass of plants using C4 photosynthesis as indicated by changes in the carbon isotope ratios of fossil tooth enamel in Asia, Africa, North America and South America.

Mantle dynamics, uplift of the Tibetan Plateau, and the Indian Monsoon
TL;DR: For example, Hou et al. as mentioned in this paper show that a small increase in the mean elevation of the Tibetan Plateau of 1000 m or more in a few million years is required by abrupt tectonic and environmental changes in Asia and the Indian Ocean.

Surface Deformation and Lower Crustal Flow in Eastern Tibet
Leigh H. Royden,B. Clark Burchfiel,Robert W. King,Erchie Wang,Zhiliang Chen,Feng Shen,Y. Liu +6 more
TL;DR: This model predicts east-west extension on the high plateau without convective removal of Tibetan lithosphere and without eastward movement of the crust east of the plateau.

Correlation between climate events in the North Atlantic and China during the last glaciation
TL;DR: The authors examined grain-size data from Chinese loess and intercalated accretionary palaeosols of last-glacial age for evidence of similar climate signals remote from the North Atlantic region.

Finite strain calculations of continental deformation .2. comparison with the india-asia collision zone
TL;DR: In this article, a thin viscous sheet model for deformation of continental lithosphere subjected to an indenting boundary condition yield distributions of crustal thickness, of stress and strain rate, and of latitudinal displacements that may be compared with observations in the India-Asia collision zone.
