Seasonal Variation in Soil and Herbage CO2 Efflux for a Sheep-Grazed Alpine Meadow on the North-East Qinghai-Tibetan Plateau and Estimated Net Annual CO2 Exchange

Frontiers in Plant Science, 2022
The Qinghai-Tibetan Plateau is a vast geographic area currently subject to climate warming. Improved knowledge of the CO2 respiration dynamics of the Plateau alpine meadows and of the impact of grazing on CO2 fluxes is highly desirable.

Grazing Exclusion Changed the Complexity and Keystone Species of Alpine Meadows on the Qinghai-Tibetan Plateau

Frontiers in Ecology and Evolution, 2021
Grazing exclusion is an effective approach to restore degraded grasslands. However, the effects of grazing exclusion on keystone species and the complexity of plant community were poorly investigated.

Soil moisture and pH differentially drive arbuscular mycorrhizal fungal composition in the riparian zone along an alpine river of Nam Co watershed

Frontiers in Microbiology, 2022
The riparian zone is an important ecological corridor connecting the upstream and downstream rivers. Its highly complex biological and physical environments significantly affect the biogeographical pattern of species and various ecosystem functions ...

Wood Microsites at Timberline-Alpine Meadow Borders: Implications for Conifer Seedling Regeneration and Alpine Meadow Conifer Invasion

Northwest Science, 2013
Abstract The importance of climate warming on forests is recognized worldwide and has increased attention on the significance of both timberline advance and alpine meadow invasion by forests. Successful seedling regeneration in alpine meadows depends on availability of suitable substrates, or microsites, for seedling establishment.

The Great Caucasus alpine belt syntaxonomy. Alpine meadows with restricted distribution

Vegetation of Russia, 2001
Alpine meadows with prevalence of perennial herbs and grasses and alpine fruticose-lichen heaths are widespread within the Great Caucasus alpine belt, 2400—3200 m above the sea level. The association Hedysaro hedysaroidis—Campanuletum collinae is met in the Western and Central Caucasus.

Quantifying the Controls on Evapotranspiration Partitioning in the Highest Alpine Meadow Ecosystem [PDF]

Water Resources Research, 2020
AbstractQuantifying the transpiration fraction of evapotranspiration (T/ET) is crucial for understanding plant functionality in ecosystem water cycles, land‐atmosphere interactions, and the global water budget. However, the controls and mechanisms underlying the temporal change of T/ET remain poorly understood in arid and semiarid areas, especially for
