In the recent several decades, glacial lakes have been expanding at the terminus of debris-covered glaciers associated with glacier shrinkage in the Himalayas. Accordingly, glacial lake outburst floods (GLOFs) have become serious natural disasters in the Himalayas. Bathymetrical surveys have been carried out at several glacial lakes, and the relationship between the lake area and water volume h...
The visit of two Tibetan physicians provided a unique opportunity to gain insight into a practice of medicine very different from that of Western civilization. Initial discussions indicated that the practice of medicine and mysticism were inextricably interwoven in the Tibetan culture. Accordingly, the focus of the study was directed to goiter, which is both common in the Himalayas and easy to ...
This document aim to develop and publish the glacial lake inventory in the Bhutan Himalayas using optical instruments onboard the Advanced Land Observing Satellite (ALOS, nicknamed “Daichi”), which was launched on January 24, 2006. The Glacial Lake Outburst Flood (GLOF) is exposing to a risk for peoples living in downstream regions. The glacial lake inventory is newly developing using ALOS data...
We present a hypothesis for the phylogeny and phylogeography of a group of bush warblers in the genus Cettia, based on parts of the mitochondrial Cytochrome b gene and the nuclear myoglobin intron II (in all approximately 1.7 kb). Ancestral areas were reconstructed by dispersal-vicariance analysis and constrained Bayesian inference. The results suggest that the insular taxa in the Cettia vulcan...
The roller coaster flight strategy of bar-headed geese conserves energy during Himalayan migrations.
The physiological and biomechanical requirements of flight at high altitude have been the subject of much interest. Here, we uncover a steep relation between heart rate and wingbeat frequency (raised to the exponent 3.5) and estimated metabolic power and wingbeat frequency (exponent 7) of migratory bar-headed geese. Flight costs increase more rapidly than anticipated as air density declines, wh...
The rich built heritage of the Himalayas has great but currently under-exploited tourism potential. Nowhere is this seen more clearly than in the Tibetan kingdom of Lc (Upper Mustang) with its intact network of medieval inns. Despite local pressure for a distinctive heritage tourism product based around upgraded inns, conventional tent-based trekking tourism still predominates. Alternatives inc...
Despite the importance of precipitation and moisture transport over the Tibetan Plateau for glacier mass balance, river runoff and local ecology, changes in these quantities remain highly uncertain and poorly understood. Here we use observational data and model simulations to explore the close relationship between summer rainfall variability over the southwestern Tibetan Plateau (SWTP) and that...
