Long-term fencing can't benefit plant and microbial network stability of alpine meadow and alpine steppe in Three-River-Source National Park.

Science of the Total Environment, 2023
A great number of fencing facilities has been established in Three-River-Source National Park. However, with the transformation of wild animals into the main consumers of grassland ecosystem and the increasing years of fence (>15 years), whether the ...

Warming reduced flowering synchrony and extended community flowering season in an alpine meadow on the Tibetan Plateau.

Ecology, 2022
The timing of phenological events is highly sensitive to climate change, and may influence ecosystem structure and function. Although changes in flowering phenology among species under climate change have been reported widely, how species-specific shifts

Mobilization of soil phosphate after 8 years of warming is linked to plant phosphorus‐acquisition strategies in an alpine meadow on the Qinghai‐Tibetan Plateau

Global Change Biology, 2021
Phosphorus (P) is essential for productivity of alpine grassland ecosystems, which are sensitive to global warming. We tested the hypotheses that (1) mobilized ‘calcium‐bound inorganic P’ (Ca‐Pi) is a major source of plant‐available P in alpine meadows ...

Warming has a minor effect on surface soil organic carbon in alpine meadow ecosystems on the Qinghai–Tibetan Plateau

Global Change Biology, 2021
The alpine meadow ecosystem on the Qinghai–Tibetan Plateau (QTP) is very sensitive to warming and plays a key role in regulating global carbon (C) cycling.

Soil microbial communities and their relationships to soil properties at different depths in an alpine meadow and desert grassland in the Qilian mountain range of China

Journal of Arid Environments, 2021
This study examined whether soil microbial composition would respond differently between alpine meadow and desert grasslands located in the Qilian mountain range in the semi-arid region of northwestern China. The measurements were carried out along a soil

Increased annual methane uptake driven by warmer winters in an alpine meadow

Global Change Biology, 2022
Pronounced nongrowing season warming and changes in soil freeze–thaw (F–T) cycles can dramatically alter net methane (CH4) exchange rates between soils and the atmosphere.

Altitudinal niches of symbiotic, associative and free-living diazotrophs driven by soil moisture and temperature in the alpine meadow on the Tibetan Plateau.

Environmental Research, 2022
Legume-associated symbiotic diazotrophs contribute more to nitrogen (N) fixation than non-symbiotic diazotrophs in many terrestrial ecosystems. However, the percentage of legume biomass is low in alpine meadows on the Tibetan Plateau.

Lateral flow between bald and vegetation patches induces the degradation of alpine meadow in Qinghai-Tibetan Plateau.

Science of the Total Environment, 2021
Bald patches (BPs) are known to accelerate and simultaneously mitigate the process of desertification. However, the mechanisms of these two synchronous actions are little studied in high desert and cold systems; and the incidence of BPs on alpine meadows

Plasticity in over-compensatory growth along an alpine meadow degradation gradient on the Qinghai-Tibetan Plateau.

Journal of Environmental Management, 2022
Over-compensatory growth of plants after disturbance is generally preferred by grassland users and managers because of more forage. How the grassland productivity and the plant growth condition before disturbance affect the compensatory growth are ...

Disentangling the assembly mechanisms of bacterial communities in a transition zone between the alpine steppe and alpine meadow ecosystems on the Tibetan Plateau.

Science of the Total Environment, 2022
Alpine meadows and alpine steppes are two major grassland types distributed on the Tibetan Plateau. Due in large part to the differences in hydrothermal and nutrient conditions following the thawing of lakeshore permafrost, alpine meadows and alpine ...
