Predicting parameters of degradation succession processes of Tibetan Kobresia grasslands [PDF]

Solid Earth, 2015
In the past two decades, increasing human activity (i.e., overgrazing) in the Tibetan Plateau has strongly influenced plant succession processes, resulting in the degradation of alpine grasslands.

Large-Scale Patterns of Soil Nematodes across Grasslands on the Tibetan Plateau: Relationships with Climate, Soil and Plants

Diversity, 2021
Soil nematodes are important contributors to soil biodiversity. Nonetheless, the distribution patterns and environmental drivers of soil nematode communities are poorly understood, especially at the large scale, where multiple environmental variables ...

Impact of Road Network Development on the Spatiotemporal Soil Erosion in the Three‐River Source Region

Land Degradation &Development, EarlyView.
ABSTRACT As a vital water conservation region in China, the Three River Source Region (TRSR) plays a critical role in safeguarding regional ecological security and ensuring the sustainable utilization of water resources. In this study, the Revised Universal Soil Loss Equation (RUSLE) was employed to quantify soil erosion in the study area across three ...

Characteristics and Influencing Factors of Soil Shear Strength in Gully Erosion at Different Developmental Segments of Subalpine Meadows

Land Degradation &Development, EarlyView.
ABSTRACT Subalpine meadows play important roles in biodiversity conservation and soil carbon sequestration, but gully erosion poses a serious threat to their ecological stability. Soil shear strength (τ) is a key mechanical parameter for evaluating gully stability and soil resistance to failure. However, the spatial variation in soil shear strength and

Taxonomic revision of the genus Tzveleviochloa (Poaceae, Aveninae) in India

Nordic Journal of Botany, EarlyView.
The taxonomy of Tzveleviochloa in India is revised based on morphological evidence, comprehensive observations of herbarium specimens and field records, and several botanical explorations in the study area. The accepted diversity is increased from two to five species, including two recently described species. The genus is distributed in the Western and

Alpine meadow degradation regulates soil microbial diversity via decreasing plant production on the Qinghai-Tibetan Plateau

Ecological Indicators
In recent decades, alpine meadows have experienced severe degradation owing to external disturbances. Although soil microorganisms are critical for ecosystem services, little is known about their responses to soil degradation and the potential patterns ...

Elevation‐dependent soil and plant responses to a decade of warming and species removal

Oikos, EarlyView.
Understanding how ecosystems retain or release carbon under warming is a critical challenge. Dominant plant species, which contribute the most biomass, can mediate ecosystem responses to warming by modifying microclimate and nutrient cycling. To investigate how warming and shifts in plant dominance interact to affect carbon and nutrient dynamics, we ...

Effects of Restoration on Community Biomass and Its Allocation in a Patchy Alpine Meadow

Grasses
The degradation of alpine meadows on the Qinghai–Tibet Plateau has seriously affected the structure and productivity of grassland communities. In this experiment, a sample area was set up in Keqihetan of Zexiong Village, Youganning Town, Henan County ...
