Mechanism of Dietary Variation of Grazing Yaks on Tibetan Plateau: The Role of Seasonal Heterogeneity of Resources

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Using DNA metabarcoding, we show that Tibetan yaks are highly selective foragers in the resource‐rich summer but switch to a diverse, generalist diet to survive the harsh winter. This flexible foraging strategy is driven by seasonal plant availability, providing strong support for optimal foraging theory and highlighting the critical need to protect ...

Quantitative MRI Values for Atrial and Ventricular Parameters in Altitude‐Dwelling Youth

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 3, Page 828-845, March 2026.
ABSTRACT Background The hypoxic environment on the Qinghai Plateau significantly exacerbates myocardial remodeling, with sex/ethnicity‐specific variations in cardiac parameters among local youth. Current cardiac MRI reference values lack data from physiologically adapted populations on this plateau.

Regional Characteristics and Typical Circulation of Extreme Precipitation in the Warm Season over the Central and Eastern Qinghai-Xizang Plateau

open access: yesGaoyuan qixiang
Based on NCEP/NCAR reanalysis data and the daily precipitation data from 105 meteorological stations in the central and eastern Qinghai-Xizang Plateau from 1982 to 2020, we investigate the spatiotemporal anomalous characteristics and major falling areas ...

Anthropogenic interference and climatic change control long‐term dissolved silicate variation in the Yellow River

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Dissolved silicate (DSi) export from rivers is shaped by both natural processes and human activities. Using long‐term observations at Lijin station combined with chemical weathering and reservoir silicon cycling models, we reconstructed annual DSi fluxes and source‐sink dynamics in the Yellow River Basin since the 1980s.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Global Trends in Day‐Night Compound Thermal Extremes in Lakes

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Lake thermal extremes, both hot and cold, profoundly impact aquatic ecosystems, yet day‐night compound events remain understudied. Using the hourly resolution Global LAke Surface water Temperature (GLAST) data set (1981–2020), we found day‐night compound hot (cold) extreme events in lakes occurred annually at 6.9% (6.9%) frequency, lasted 3.7 (

Effects of environmental factors on genetic diversity in the endangered Notopterygium incisum from the southeastern Qinghai–Tibetan Plateau

open access: yesPlant Species Biology, Volume 41, Issue 2, March 2026.
This study focuses on 38 populations of Notopterygium incisum from its main distribution areas (Sichuan Province, Gansu Province, and Qinghai Province), conducting molecular genetic diversity analysis and investigating the correlations between genetic variation and climatic variables, geographical distribution, and elevation gradients.

Reduced Upwind Moisture Transport Contributes to Drought in the Agro‐Pastoral Ecotone of Northern China

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract It remains unclear how changes in moisture supply drive droughts in the Agro‐Pastoral Ecotone of Northern China (APENC), where ecological restoration and food security are increasingly vulnerable under warming. Using a moisture‐tracking model, we quantify the moisture sources of APENC's precipitation and its trends, and reveal mechanisms ...
