Late Pleistocene Volcanic Rocks From Tengchong Volcanic Field at SE Tibetan Plateau: Constraints on Petrogenesis and Mantle and Crustal Processes

Geological Journal, EarlyView.
Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...

Independent leaf and root responses to autumn freezing in perennial herbs: Insights from cutting and transplant manipulations

Grassland Research, EarlyView.
In this study, we compared two sampling approaches to assess autumn freezing resistance. Our goal was to determine whether the commonly employed cutting method, which disrupts root‐tissue connectivity, provides a valid measure of true freezing resistance.

Gut microbiome seasonality is associated with dietary plasticity and coexistence in three sympatric Pamir ungulates

iMetaOmics, EarlyView.
This graphical abstract outlines a multi‐omics framework investigating the seasonal dietary composition and gut microbial communities of three coexisting ungulate species inhabiting the extreme high‐altitude Pamir Plateau (Ovis ammon polii, Capra sibirica, and Pseudois nayaur). By integrating dietary DNA metabarcoding, 16S rRNA gene sequencing, shotgun

Expansion of the Tibetan Plateau during the Neogene [PDF]

Nature Communications, 2017
AbstractThe appearance of detritus shed from mountain ranges along the northern margin of the Tibetan Plateau heralds the Cenozoic development of high topography. Current estimates of the age of the basal conglomerate in the Qaidam basin place this event in Paleocene-Eocene.

Spatial Patterns of Seed Plants and Their Conservation Priorities in Jiangxi Province, China 中国江西省种子植物的空间格局及其保护优先区

Integrative Conservation, EarlyView.
We comprehensively evaluated the seed plant diversity of Jiangxi province to address the regional biodiversity conservation of Asian subtropical evergreen broad‐leaved forests (EBLFs). Higher species diversity of seed plants was observed in eastern, southern, and western Jiangxi, with elevation and precipitation as mainly environmental factors.

The Significant Impact of Lost Species' Identity, Number and Abundance on Functional Structure of Alpine Meadow

Ecology and Evolution
Biodiversity, the cornerstone of ecosystem functions and services, faces threats from anthropogenic climate change. However, it remains unclear how species loss, including abundance, number, and identity of lost species, would alter the functional ...

Spatiotemporal Changes and Climate Driving Factors of Compound Precipitation‐Temperature Extreme Events Across Global Land Areas

International Journal of Climatology, EarlyView.
During the period 1901–2024, the dominant proportion of compound dry‐warm extremes in annual, June–July–August (JJA), and December–January–February (DJF) occurrences was the highest among the four types of compound precipitation and temperature extremes across global land areas, accounting for 40.1%, 50.3%, and 28.0%, respectively.

Land‐Atmosphere Coupling Is Associated With Severer Vegetation Productivity Losses During Compound Dry‐Hot Events in Drylands

International Journal of Climatology, EarlyView.
Compound dry‐hot events (CDHEs) exerted severer damage on vegetation productivity for temperate shrublands, savannas and grasslands in drylands. Land‐atmosphere coupling was associated with severer negative impacts of CDHEs through soil moisture–temperature feedback, especially for dry‐event‐leading CDHEs.

Lightweight Deep Learning for Real-Time River Surface Velocity Estimation From Low-Altitude Drone Remote Sensing

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Drone-based-low-altitude remote sensing has become an important means for hydrological monitoring, where real-time on-device perception of both waterbody extent and surface flow velocity is urgently required.

Compound Meteorological and Hydrological Hot‐Dry and Hot‐Wet Extremes Over Global Land Areas: Spatiotemporal Changes, Attribution, and Drivers

International Journal of Climatology, EarlyView.
The changes in joint return period of compound meteorological hot‐dry (CMHHE) and hot‐wet (CMHWE) and compound hydrological hot‐dry (CHHDE) and hot‐wet (CHHWE) extremes were attributed to changes in associated univariate extremes and their dependence.
