Vegetation Structure and Temperature Regimes of Tropical Alpine Treelines [PDF]

open access: yesArctic, Antarctic, and Alpine Research, 2007
Alpine treeline ecotones can be gradual transitions, abrupt boundaries, or patchy mosaics, and these different patterns may indicate important processes and dynamic properties. We present observed spatial patterns of a wide range of tropical treelines and try to explain these patterns.

The aridity index governs the variation of vegetation characteristics in alpine grassland, Northern Tibet Plateau [PDF]

open access: yesPeerJ, 2019
The vegetation dynamic (e.g., community productivity) is an important index used to evaluate the ecosystem function of grassland ecosystem. However, the critical factors that affect vegetation biomass are disputed continuously, and most of the debates ...

Classification of alpine grasslands in the western Tian Shan Mountains (Kyrgyzstan, Middle Asia)

open access: yesActa Societatis Botanicorum Poloniae, 2023
In this paper, we present the first syntaxonomic classification of alpine grasslands in the western Tian Shan Mountains (Kyrgyzstan) with some remarks on its environmental gradients. A total of 251 relevés were sampled in 2015-2022 using the seven-degree

Vegetation NDVI Linked to Temperature and Precipitation in the Upper Catchments of Yellow River [PDF]

open access: yes, 2012
Vegetation in the upper catchment of Yellow River is critical for the ecological stability of the whole watershed. The dominant vegetation cover types in this region are grassland and forest, which can strongly influence the eco-environmental status of ...

Is grazing exclusion effective in restoring vegetation in degraded alpine grasslands in Tibet, China? [PDF]

open access: yesPeerJ, 2015
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.

Soil Moisture Variations in Response to Precipitation Across Different Vegetation Types on the Northeastern Qinghai-Tibet Plateau

open access: yesFrontiers in Plant Science, 2022
An understanding of soil moisture conditions is crucial for hydrological modeling and hydrological processes. However, few studies have compared the differences between the dynamics of soil moisture content and soil moisture response to precipitation ...

Impact of soil application with selenite and selenate on ‘soil-highland barley-dietary’ system in Tibet

open access: yesFrontiers in Plant Science
IntroductionSelenium (Se)-fortified foods have demonstrated efficacy in augmenting dietary Se intake and ameliorating human Se nutritional status. To mitigate Se deficiency-related health risks in Tibetan populations, systematic biofortification trials ...
