Plant diversity is closely related to the density of zokor mounds in three alpine rangelands on the Tibetan Plateau [PDF]

open access: yesPeerJ, 2019
Background Plateau zokor (Myospalax baileyi) is a subterranean rodent endemic to the Tibetan Plateau. This species has been generally viewed as a pest in China due to the competition for food with livestock and also causing soil erosion.

Tree growth acceleration and expansion of alpine forests: The synergistic effect of atmospheric and edaphic change. [PDF]

open access: yes, 2016
Many forest ecosystems have experienced recent declines in productivity; however, in some alpine regions, tree growth and forest expansion are increasing at marked rates.

Plant community dynamics during the growing season of typical ecosystems on the Tibetan Plateau

open access: yesGeography and Sustainability, 2020
The relationships between vegetation and environmental factors have always been a core concern of ecologists. The dynamic characteristics of plant communities during the growing season can directly reflect these relationships, so we examined this issue ...

Response of forage nutrient storages to grazing in alpine grasslands

open access: yesFrontiers in Plant Science, 2022
Forage nutrient storages can determine livestock size and husbandry development. There is insufficient research on the response of forage nutrient storages to grazing and related driving mechanisms in alpine grasslands, especially on the Tibetan Plateau.

Continuous grazing in comparison to cutting management on an organic meadow in the eastern Alps [PDF]

open access: yes, 2010
Continuous grazing is an appropriate pasture system for dairy cows in low input milk production systems like organic farming. Grazing increases for economic reasons and is also caused by regulations in organic farming.

Restoration Practices Affect Alpine Meadow Ecosystem Coupling and Functions

open access: yesRangeland Ecology & Management, 2020
Degradation of alpine meadows on the Qinghai-Tibetan Plateau is an important issue for ecological science, policy making, and the welfare of local herders. Destruction of alpine meadows results from degeneration of vegetation and soil systems and from the mechanical decoupling of the environment, grassland, livestock, and herders and, subsequently ...

Variation and control of soil organic carbon and other nutrients in permafrost regions on central Qinghai-Tibetan Plateau

open access: yesEnvironmental Research Letters, 2014
The variation and control of soil organic carbon (SOC) and other nutrients in permafrost regions are critical for studying the carbon cycle and its potential feedbacks to climate change; however, they are poorly understood.

Insight into influence of roots on hydrothermal properties of alpine meadow in Tibetan Plateau

open access: yesFrontiers in Environmental Science, 2023
The physical and mechanical behavior of alpine meadow in Tibetan Plateau is now attracting widespread attention. In this paper, a series of experiments were conducted to study the influence of roots on hydrothermal behavior of alpine meadow located at ...

Monitoring Polycyclic Aromatic Hydrocarbon Concentrations in Austin, TX, After the Coal-Tar Sealant Ban [PDF]

open access: yes, 2012
Polycyclic Aromatic Hydrocarbons (PAH) are a group of chemicals consisting of three or more fused benzene rings. Many of this group of compounds are considered Toxic Pollutants and listed as Priority Pollutants by the EPA.

Plant community responses to warming modified by soil moisture in the Tibetan Plateau

open access: yesArctic, Antarctic, and Alpine Research, 2020
Predicted warming in Tibetan Plateau may have profound effects on plant community structure and function. We used open-top chambers to artificially warm two different plant communities in Tibet from 2012 to 2016.
