Behavioral mechanisms of male sterilization on plateau pika in the Qinghai-Tibet plateau

Behavioural Processes, 2012
Fertility control is an alternative non-lethal method in the management of rodents. Previous modeling suggests that the efficacy of male sterilization depends on mating systems of animals, but behavioral mechanisms of male sterilization have not been investigated. Here we investigated the behavioral mechanism of the sterilant quinestrol in reducing the

A Study on the Detection of Deformation of Tuotuohe Area on the Qinghai-Tibet Plateau

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
In permafrost regions, the ground surface deformation is closely related to the ice-water phase transition process in active layer and underground ice. It is of great significance to carry out ground surface deformation detection research for understanding the development of permafrost in the Qinghai- Tibet Plateau. The InSAR technology has been proved

Vertical distribution of Pu in forest soil in Qinghai-Tibet Plateau

Journal of Environmental Radioactivity, 2021
The 239+240Pu and 137Cs activities and 240Pu/239Pu atom ratios in surface soil and soil core collected from Qinghai-Tibet Plateau were investigated. The maximum of 239+240Pu and 137Cs activity concentrations in five soil cores were found in upper layers and have a same trend: the maximum followed by exponential decline.

Microplastics in Qinghai-Tibet Plateau and Yunnan-Guizhou Plateau lakes, China

Science of The Total Environment
As an emerging environmental pollutant, microplastics (MPs) have received widespread attention. Recently, studies examining microplastic pollution in plateau lakes have been increasing, but few have examined the distributions, sources, and fates of MPs in different plateau areas. In this work, the abundances and characteristics of MPs in surface waters

The Electrical Structure of Northeastern Qinghai-Tibet Plateau

Chinese Journal of Geophysics, 2005
The electrical conductivity model of the crust beneath northeastern Qinghai-Tibet is obtained from inverting TE and TM mode responses simultaneously using the non-linear conjugate gradient inversion (NLCG) algorithm. The result shows that there exist high electrical conductivity layers in the middle and lower crust beneath the northeastern Qinghai ...

Coherence based analysis of distributed scatterers in the Qinghai-Tibet Plateau

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
In Qinghai-Tibet Plateau, permafrost is usually full of ice underground and sensitive to the temperature. So due to the global warming and seasonal change of temperature, great changes of surface in physical characteristics would occur in the temporal dimension.

The process and mechanism of the rise of the Qinghai-Tibet Plateau

Tectonophysics, 1996
Abstract During the period from the Late Cretaceous to Eocene, the Qinghai-Tibet Plateau started a new stage of continental collision, crustal shortening and thickening and continuous rise. The rising process of the Plateau progressed through three stages: rise due to subduction collision, rise due to convergence compression and rise due to isostatic

Prevalence of Eimeria Infection in Yaks on the Qinghai-Tibet Plateau of China

Journal of Parasitology, 2012
Few data are available on the prevalence of Eimeria spp. in yaks. An observational study was conducted to determine the prevalence of coccidial infection in yaks on the Qinghai-Tibet Plateau of China. A total of 324 fecal samples from 4 counties was examined, and oocysts were identified to the species level on the basis of morphological features ...

Xanthone glycosides in Gentianceae of Qinghai-Tibet plateau

1999
Abstract Most species of Gentianaceae in Qinghai-Tibet Plateau are traditional Tibetan medicines which were used for stabilizing liver functions and improving the gallbladder. They were used for curing hepatitis, cholecystitis and other diseases.
