Overgrazing‐Induced Root Carbohydrate Depletion During Winter Dormancy Drives the Decline of Stipa purpurea Populations in the Tibetan Alpine Steppe

Land Degradation &Development, EarlyView.
ABSTRACT Plant carbon allocation and physiology are influenced by overgrazing during the growth period. However, the response of plant physiological processes to overgrazing during winter dormancy remains unclear. We analyzed root physiological processes of Stipa purpurea in winter dormancy across three plots: over grazing (FG), exclusions of 2 years ...

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

Effects of all-trans retinoic acid and oxygen concentration on the proliferation and differentiation of subcutaneous adipocytes in yak

Frontiers in Veterinary Science
In this study, we investigated the mechanism by which all-trans retinoic acid (ATRA) regulates the hypoxic adaptation of yak subcutaneous adipocytes through a dose-dependent regulation.

Post‐Fire Soil Organic Carbon Dynamics: Decline and Recovery Over Two Decades

Land Degradation &Development, EarlyView.
ABSTRACT Wildfire can significantly alter soil organic carbon (SOC) dynamics in forest ecosystems, with complex temporal patterns following fire events. However, research on post‐fire SOC recovery remains limited, particularly in dry‐warm valley regions that are prone to frequent forest fires.
