INTRODUCTION Road traffic can play an important role in strengthening regional economic activities, especially at high altitude, and it is necessary to know important traffic-related information. Although previous studies reported on road traffic in China, there has been little research on high-altitude road traffic to date. METHOD The annual official census of road traffic safety from 2006 t...

The culminating philosophy and practice for Buddhist traditions in Tibet is what is found in tantra, or Vajray ā na. Yet Tibet is unique in the Buddhist world in that it is a place where not only the traditions of tantra (for which it is widely known) are practiced, but where the epistemological traditions of valid cognition ( pram āṇ a ) and what came to be known as Pr ā sa ṅ gika-Madhyamaka a...

Carbonate oxygen isotope paleoaltimetry is based on analysis of the dO value of carbonate precipitated from surface water. Deciphering the diagenetic history is important for establishing whether particular carbonates are accurate recorders of paleosurface waters, which reflect paleoelevation. This study provides examples from southern, east–central, and northeastern Tibet of approaches aimed a...

Tibet makes up the majority of the Qinghai-Tibet Plateau, often referred to as the roof of the world. Its complex landforms, physiognomy, and climate create a special heterogeneous environment for mosses. Each moss species inhabits its own habitat and ecological niche. This, in combination with its sensitivity to environmental change, makes moss species distribution a useful indicator of vegeta...

The Tibetan Plateau is the highest and largest plateau in the world, generated by the collision of India and Eurasia. Details of this continent-continent collision and the uplift mechanism of the plateau are still hotly debated. In this study, I collected a large amount of seismic waveform data recorded by more than 300 stations in Tibet and its northern neighbor Tien Shan. I processed the data...

Overgrazing is considered one of the key disturbance factors that results in alpine grassland degradation in Tibet. Grazing exclusion by fencing has been widely used as an approach to restore degraded grasslands in Tibet since 2004. Is the grazing exclusion management strategy effective for the vegetation restoration of degraded alpine grasslands? Three alpine grassland types were selected in T...

Ethnic Tibetan populations are distributed over an area as vast as Western Europe. They are found not only in the Tibet Autonomous Region (of China), the traditional heartland of political Tibet, but also in parts of the neighbouring Chinese provinces of Qinghai, Sichuan, Gansu, Yunnan and Xinjiang, as well as in parts of other nations such as India (Ladakh, Sikkim, Northern Uttar Pradesh and A...

[1] Two of the most popular mechanisms for thickening the crust beneath the Tibetan Plateau are (1) pure shear with faulting and folding in the upper crust and horizontal shortening below and (2) flow of lower or middle crust without significant shortening of the upper crust. To help discriminate between the relative contributions of these two mechanisms, well-constrained estimates of upper cru...

The use of snow and ice cores as recorders of environmental contamination is particularly relevant for per- and polyfluoroalky substances (PFASs) given their production history, differing source regions and varied mechanisms driving their global distribution. In a unique study perfluoroalkyl acids (PFAAs) were analyzed in dated snow-cores obtained from high mountain glaciers on the Tibetan Plat...

BACKGROUND & OBJECTIVES Culex tritaeniorhynchus is the primary vector of Japanese encephalitis virus (JEV) which is a major threat to animals and humans health. This virus has been reported earlier from low altitude regions of Tibet, in mosquitoes, Tibetan pigs and local Tibetans, but no reports are available for the probable propagation of JE to high altitude regions (3100 m) of Tibet. This st...
