Hierarchical Drivers Shaping the Global Patterns of Soil Organic Carbon

open access: yesEarth's Future
Recent advancements in observational data and experimental research have significantly enhanced our understanding of the mechanisms governing the magnitude, distribution, and dynamics of soil organic carbon (SOC) patterns.

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

open access: yesLand 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 ...

Paleoclimate and vegetation records from the Himalayan foreland basin during the Cenozoic Himalayan exhumation

open access: yesDiscover Geoscience
The Siwalik Group is a key laboratory for the study of the Neogene environment. The lower unit of the Siwalik Group was deposited in a meandering river system (between ~ 16 and 10 Ma) that changed to braided during the deposition of the Middle Siwalik ...

Asymmetric Responses of Ecosystem Health to Urbanization in a Typical Karst City: Spatiotemporal Patterns and Driving Mechanisms in Guilin, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Urban expansion can substantially reshape ecosystem structure and functioning, especially in ecologically fragile Karst landscapes. Clarifying how ecosystem health (EH) responds to urbanization and identifying the factors that drive spatial variation in EH are important for regional sustainability.

Particle Size as a Key Driver of Black Carbon Wet Removal: Advances and Insights

open access: yesAtmosphere
Black carbon (BC), as a potent light-absorbing aerosol, is mainly removed from the atmosphere through wet deposition. The efficiency of this process depends on the capacity of BC particles to serve as cloud condensation nuclei (CCN) or ice nuclei (IN ...

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Global trends in epilepsy and the Chinese experience: Epidemiological transitions, underlying mechanisms, and integrated strategies (1990–2021)

open access: yesNeuroprotection, EarlyView.
Epilepsy: Global Trends and the Chinese Experience (1990–2021). The infographic depicts (left) the global distribution of age‐standardized epilepsy DALY rates; (center) the triple inequality gap within China, including regional mortality disparities (9‐fold difference between western and eastern provinces), urban‐rural treatment gaps (60%–90%), and ...

Petrocosmea wentsaii sp. nov. (Gesneriaceae) from Guizhou, China

open access: yesNordic Journal of Botany, EarlyView.
Petrocosmea wentsaii M.Q. Han, Miao.M. Wang & Yan Liu, a new species from Guizhou, China, is described and illustrated. Petrocosmea wentsaii was found on damp walls in a huge limestone cave. It is most similar to Petrocosmea hexiensis S.Z. Zhang & Z.Y. Liu in the conformation of the corolla.

Road air pollution harms the reproductive success of a bee‐pollinated wildflower: A dusty threat to biodiversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Dust, a common form of air pollution, is particularly problematic on roadsides, which are important habitats for plants and pollinators. We investigated whether and how road dust affects plant sexual reproduction using Primula chungensis in a biodiversity hotspot. Our study provides compelling evidence that road dust can harm plant reproductive success

How interference between the North Atlantic Oscillation and the tropical Indo‐Pacific convection modulates wave trains along the subtropical jet: Impacts on the Asian winter climate

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study reveals that the combined effects of the North Atlantic Oscillation (NAO) and anomalous Indo‐Pacific Walker circulation on the excitation of the wave train along the wintertime subtropical jet strongly depend on their phase combination. Their impacts interfere constructively or destructively over South Asia, leading to notable differences in
