Vulnerability to Dams of the Last Undammed Large Rivers of Southeast Asia

River Research and Applications, EarlyView.
ABSTRACT The vast majority of large Eurasian rivers are regulated by hydropower dams, but some have survived as free‐flowing rivers so far in the Arctic and along stretches of the Myanmar coast. There, the Ayeyarwady (Irrawaddy) and Salween Rivers, two of the largest rivers of Southeast Asia, provide a huge amount of sediment, nurturing floodplains and

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 ...

Tectonic Evolution and Crustal Growth of the East Kunlun Orogen, NW China: Insights From the Late Permian–Triassic Granitoids

Geochemistry, Geophysics, Geosystems
The East Kunlun Orogen (EKO) on the northern margin of the Tibetan Plateau experienced complex Late Paleozoic–Early Mesozoic tectono‐magmatic activities associated with the subduction and closure of the Paleo‐Tethys Ocean.

Radio Interference Prediction Method for EHV AC Transmission Lines at High Altitudes Based on Long‐Term Observations

High Voltage, EarlyView.
ABSTRACT Radio interference (RI) is a critical factor in the design of extra‐high voltage (EHV) transmission lines at high altitudes. To address the insufficient field data of RI on high‐altitude transmission lines, the lack of adequate validation for existing RI prediction methods, and the difficulty in assessing RI levels under various meteorological

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.

Late Quaternary fluctuation in upper range limit of trees shapes endemic flora diversity on the Tibetan Plateau

Nature Communications
The influence of paleoclimate in shaping current biodiversity pattern is widely acknowledged. However, it remains unclear how the upper paleo-range limit of trees, which dictated the habitat of endemic alpine species, affects the variability in endemic ...

Multi‐level nitrogen and phosphorus addition synergistically reduces alpine grassland stability via species compositional changes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nutrient addition generally weakens the stabilizing effects of plant diversity on grassland productivity. However, whether this destabilizing effect is associated with species compositional changes and varies with nutrient input levels remains unclear.

Precipitation‐mediated asymmetric fitness consequences of nectar robbing in distylous Primula florindae

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowers with deep corollas are frequently associated with nectar robbing, a behaviour that often reduces pollen transfer and seed production. Robbing scars, however, may further affect plant reproductive success through rainwater entry into corolla tubes.

Grazing reverses climate-induced soil carbon gains on the Tibetan Plateau

Nature Communications
Soil carbon stocks on the Tibetan Plateau are widely considered to be increasingly threatened by drastic climate warming and intensified livestock grazing. But it remains elusive due to unconstrained model projections.

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

Integrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.
