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

Divergent Climate Sensitivities of the Alpine Grasslands to Early Growing Season Precipitation on the Tibetan Plateau

Remote Sensing, 2022
Warming is expected to intensify hydrological processes and reshape precipitation regimes, which is closely related to water availability for terrestrial ecosystems.

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.

Spatiotemporal Coupling Relationship Between Plateau Pika Disturbance and Alpine Meadow Degradation

Shuitu baochi tongbao, 2023
[Objective] Plateau pika (Ochotona curzoniae) is a key species in the alpine meadow ecosystem of the Qinghai-Xizang Plateau. The coupling relationship between pika activity and meadow degradation was analyzed in order to further improve the observation ...

Microbial Community Response to Alpine Meadow Degradation and Its Impact on Soil Nutrient Cycling

Agronomy
The degradation of alpine meadows on the Qinghai–Tibet Plateau is a major issue affecting both the ecology and the economy. Microorganisms play an important role in soil nutrient cycling and the regulation of ecosystem function.

Nitrogen economy of alpine plants on the north Tibetan Plateau: Nitrogen conservation by resorption rather than open sources through biological symbiotic fixation

Ecology and Evolution, 2020
Nitrogen (N) is one of the most important factors limiting plant productivity, and N fixation by legume species is an important source of N input into ecosystems.

Variations and Mutual Relations of Vegetation–Soil–Microbes of Alpine Meadow in the Qinghai-Tibet Plateau under Degradation and Cultivation

Land, 2022
Artificial cultivation had been applied to recover the meadow suffering from serious degradation in the Qinghai–Tibet Plateau. Studies focusing only on the changes in vegetation, soil and microbes along the meadow degradation were insufficient, and ...

Differentiation in the Underground Bud-Bank Structure of Poa pratensis Across Contrasting Alpine Grassland Habitats on the Eastern Qinghai–Tibetan Plateau

Plants
Underground bud banks play a critical role in vegetative regeneration of alpine grassland plants, but how species-level underground regenerative structures vary across contrasting habitats remains unclear.
