New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Elevational variations of leaf morphological traits and its responses to simulated climate warming in Tibetan alpine meadows

Global Ecology and Conservation
Both climate and environment changes can lead to variations in leaf morphological traits within or among herbaceous species. However, evidence for leaf morphological traits of alpine herbaceous species shifts with elevations, particularly under climate ...

Levels of Germinable Seed in Topsoil and Yak Dung on an Alpine Meadow on the North-East Qinghai-Tibetan Plateau

Journal of Integrative Agriculture, 2013
In order to clarify the interactive mechanism between grazing yak and alpine meadow on the Qinghai-Tibetan Plateau, our study assessed seed density (by species) in the topsoil of alpine meadow with different grazing intensities in the Tianzhu area, north-

Effects of Desertification on Phosphorus Fractions of Alpine Meadow Soils

Shuitu baochi tongbao, 2023
[Objective] Soil phosphorus fractions determine the migration and availability of phosphorus during soil evolution. The spatial distribution characteristics of soil phosphorus fractions in alpine meadows under different desertification levels were ...

Species‐Specific Shrub Encroachment Drives Divergent Soil Fungal Assembly Processes and Network Structures in Alpine Meadows

Land Degradation &Development, EarlyView.
ABSTRACT Shrub encroachment is rapidly transforming alpine meadow ecosystems worldwide, yet its consequences for belowground microbial organization remain insufficiently understood, particularly when different shrub species exert contrasting ecological effects.

Biomass partitioning and its relationship with the environmental factors at the alpine steppe in Northern Tibet. [PDF]

PLoS ONE, 2013
Alpine steppe is considered to be the largest grassland type on the Tibetan Plateau. This grassland contributes to the global carbon cycle and is sensitive to climate changes. The allocation of biomass in an ecosystem affects plant growth and the overall

Asymmetric Response of Soil Heterotrophic Respiration and Its Temperature Sensitivity in a Desert Steppe Under Climate Change

Land Degradation &Development, EarlyView.
ABSTRACT Soil heterotrophic respiration (Rh) and its temperature sensitivity (Q10) are important variables reflecting the intensity of feedback between the grassland carbon cycle and climate change. However, the factors regulating Rh and Q10 in desert grasslands under climate change remain unclear, and the asymmetric response of Rh during warming and ...

Freeze–thaw cycle frequency affects root growth of alpine meadow through changing soil moisture and nutrients

Scientific Reports, 2022
Alpine meadows grow in alpine regions and play an important role in the production and life of alpine regions. As a unique feature of alpine regions, freeze–thaw cycles (FTCs) affect the growth of alpine meadows.

Patterns, Dynamics, and Drivers of Soil Available Nitrogen and Phosphorus in Alpine Grasslands across the QingZang Plateau

Remote Sensing, 2022
Soil available nutrient contents are critical for regulating ecosystem structure and function; therefore, exploring patterns, dynamics, and drivers of soil available nutrient contents is helpful for understanding the geochemical cycle at the regional ...

Integrated Prediction and Analysis of Soil Erosion and Soil Organic Carbon Loss in the Dayekou Watershed, Qilian Mountains

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion poses a critical threat to ecological security in mountain watersheds worldwide. Predicting its dynamics and associated soil organic carbon (SOC) loss remains an ongoing challenge during the 21st century due to complex interactions among climate, land use, and topography.
