Detecting Plateau Zokor (Eospalax baileyi) Mounds in UAV Imagery of Alpine Meadows Using Deep Learning Algorithms

Remote Sensing in Ecology and Conservation, EarlyView.
We developed PZM‐YOLO to automatically detect plateau zokor mounds in UAV imagery of alpine meadows. The model achieved reliable detection of small and densely distributed mounds under complex backgrounds, outperforming the baseline YOLOv5s. This framework supports mound counting, mound position, rodent impact assessment, and grassland restoration ...

Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China 气候变化下中国大兴安岭漠河地区猞猁潜在适宜区的变化

Wildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

UVB-induced HaCat cell damage and Myricaria Paniculata’s molecular effects

Scientific Reports
The Qinghai‒Tibet Plateau, the “Roof of the World” in China, has high altitude, low pressure, thin air, little rain, long sunshine, and snow cover, causing 80–90% more Ultraviolet (UV) reflectance and greater skin UV exposure at high altitudes. Myricaria

Simulation of Daily Precipitation from CMIP5 in the Qinghai-Tibet Plateau

SOLA, 2019
As the earth's third pole, Qinghai-Tibet Plateau belongs to one of the most sensitive regions to climate change in the world. Based on the observed and the simulated daily precipitation from the Coupled Model Intercomparison Project Phase 5 (CMIP5), we evaluated the simulation performance of daily precipitation from selected CMIP5 models from 1975 to ...

Mechanism of Damage and Micro‐Characterisation of Irradiation‐Induced Free Radicals on the Epoxy Insulation of the Bridge Arm Reactors at High Altitude

High Voltage, EarlyView.
ABSTRACT Damage degradation of epoxy resin insulating materials by free radicals triggered by the ultraviolet irradiation environment at high altitude has become a key issue that restricts the reliability of the bridge arm reactor at high altitude.

Quantitative comparison and evaluation between aerial and underground parts of Gentiana straminea through simultaneous determination of five major compounds by RP-HPLC

Heliyon
Herbal Gentiana straminea Maxim. (Family Gentianaceae), “Ma Hua Jiao” in Chinese, is a commonly used Chinese medicine. Secoiridoids and flavonoids have been identified as the major active components of herbal medicines used in the treatment of hepatitis,

Mainland diversification and recent island lineages in the reduviid genus Tapirocoris: an integrative taxonomic framework with four new species

Insect Science, EarlyView.
Using an integrative taxonomic framework that combines COI DNA barcodes, geometric morphometrics and phylogeography, we revise the assassin bug genus Tapirocoris and recover seven well‐supported species, including four newly described cryptic species.

Experimental Insights on Carbon Sequestration and Yield Improvement in Oat Fields with 30% Organic Nitrogen Substitution in the Tibetan Plateau

Agronomy
To evaluate the optimal substitution ratio of organic fertilizer for chemical nitrogen fertilizer and its underlying mechanisms, a pot experiment was conducted in the rhizosphere soil of oat (Avena sativa) on the Qinghai–Tibet Plateau.

Resource Availability and Habitat Quality Drive Time‐Lag Effects in High‐Altitude Ungulate Distribution

Integrative Zoology, EarlyView.
Our analysis revealed that while climate strongly influenced species distributions, habitat change drove most observed delays in distribution responses. In terms of community ecology, dispersed communities exhibited shorter time lags than concentrated groups. Analyses of lag duration revealed a 5–6‐year distribution lag effect in high‐altitude ungulate
