Does wetland degradation impact bird diversity differently across seasons? A case study of Zoige Alpine Wetland ecosystem

Avian Research, 2023
Wetland degradation is an escalating global challenge with profound impacts on animal diversity, particularly during successional processes. Birds, as highly mobile and environmentally sensitive organisms, serve as effective indicators of ecological change.

The Aridity Threshold of Soil Organic Carbon Density Along the Climate Aridity Gradient in the Alpine Ecosystem of the Qinghai‐Tibetan Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Soil organic carbon density (SOCD) is a key indicator for evaluating the stability of soil carbon pools, especially in alpine ecosystems that are sensitive to climate change. However, research on the response of SOCD to different aridity gradients is still limited. Therefore, we conducted extensive sampling along different aridity gradients of

Allelic variations in GA20ox3 regulate fruit length and seed germination timing for high-altitude adaptation in Arabidopsis thaliana

Nature Communications
Altitude significantly affects both fruit length (FL) and seed germination timing (SGT) in plants. Alpine plants often require prolonged chilling to enhance seed germination rates, yet the molecular mechanisms underlying these adaptations remain largely ...

Significant Imbalance Between Human Activities and Ecosystem Services in the Tibet Autonomous Region of China: Evidence From an Improved Coupling Coordination Degree Model

Land Degradation &Development, EarlyView.
ABSTRACT Maintaining balanced interactions between humans and ecosystems in plateau regions is critical to achieving global sustainable development. However, existing methodologies are insufficient to fully elucidate the complex coupling and coordination relationships between human activities and ecosystems, as well as the sustainable development ...

Shrub encroachment alters the diversity of soil fungal communities in topsoil, but not in subsoil under alpine grassland of the Qinghai-Tibetan plateau

Global Ecology and Conservation
Encroachment of alpine grassland ecosystems by shrubs is widespread in the Qinghai-Tibetan Plateau. However, effects of shrub encroachment on fungal community structure and its function are limited.

Response of Soil Fungal Communities to the Alpine Steppe Degradation Gradient

Land Degradation &Development, EarlyView.
ABSTRACT The degradation of alpine steppe on the Qinghai‐Tibet Plateau has become a critical ecological security issue. Soil fungi, as core regulators of grassland ecosystem functioning, play a pivotal role in mediating the feedback between degradation and soil ecological processes.

Multi‐Scale Pathways to Integrated Protection and Restoration of Mountains, Rivers, Forests, Farmlands, Lakes, and Grasslands in the Three Gorges Reservoir Area: A Social‐Ecological Systems Perspective

Land Degradation &Development, EarlyView.
ABSTRACT Human activities have intensified eco‐environmental problems, challenging harmonious human‐nature interactions. However, existing integrated protection and restoration (IPR) zoning approaches for mountains, rivers, forests, farmlands, lakes, and grasslands (MRFFLG) focus on a single scale and fail to incorporate the ecological network (EN) and

Dynamic monitoring and restorability evaluation of alpine wetland in the eastern edge of Qinghai–Tibet Plateau

Global Ecology and Conservation
Accurate monitoring of alpine wetland areas and scientific evaluation of alpine wetland restorability play important roles in revealing the changing mechanism of the ecological environment. However, because of the complexity and lack of spatial data, few

A Study on the Distribution Characteristics of Salinity and Nutrients and the Migration Mechanism of Soil Salt in the Delingha Saline‐Alkali Soil Profile of the Qaidam Basin

Land Degradation &Development, EarlyView.
ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt ...

Internal Permafrost Structure of Geomorphologically Distinct Palsas in Northern Sweden Revealed by Quasi‐3D ERT

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost in northern peatlands occurs within individual palsas or extensive peat plateaus and controls local carbon storage. These permafrost landforms are complex, and their internal structure remains poorly understood. We used quasi‐3D electrical resistivity tomography (ERT) measurements, supported by UAV‐LiDAR topography, frost probing ...
