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 ...

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.

Transcriptional Profiling and Key Enzyme Activity of Epichloë sinensis Isolated from Festuca sinensis in Response to Na₂SeO₃

Fermentation
Fungal endophytes exhibit symbiotic relationships with their host plants and convert inorganic selenium to organoselenium and Se0. In order to elucidate how Epichloë sinensis from Festuca sinensis adapts to different concentrations of sodium selenate ...

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

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.

Updated Chorotypes of Terrestrial Vertebrates Shed New Light on Zoogeographical Regions in China

Integrative Zoology, EarlyView.
Chorotype represents a fundamental concept for identifying groups of species that share similar distribution patterns. However, the last comprehensive revision of animal chorotypes in China was performed more than a decade ago. Here, we update the chorotype classifications for 1040 species and propose an updated zoogeographical regionalization scheme ...

Effects of different mixed sowing ratios of oat and forage pea on forage yield and quality in alpine region

Frontiers in Plant Science
To optimize planting patterns for artificial grassland in the Guinan area, this study systematically compared the forage productivity, nutritional quality, and feeding value of four oat (Avena sativa L.)–forage pea (Pisum sativum L.) mixture ratios (8:2,
