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

open access: yesHigh 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.

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

open access: yesNature 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.

Soil N:P ratio influences species coexistence via nitrogen‐form niche differentiation in alpine grasslands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant species coexistence in nutrient‐limited ecosystems is often maintained by niche differentiation in nitrogen (N) uptake. However, how this partitioning responds to changes in nutrient stoichiometry is still poorly understood.

Dynamic rhizosphere C:N:P stoichiometry of plants, soils and microbial biomass under different grazing patterns

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Analysing grassland ecological stoichiometry is crucial for evaluating ecosystem quality and health via energy flow and elemental equilibrium. Grazing is a dominant human activity shaping alpine grasslands on the Qinghai–Tibet Plateau (QTP), yet few studies have used ...

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

open access: yesNature 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 ...

Nitrogen addition alters adaptive strategies of a dominant plant species in an alpine meadow via shifts in traits and trait coordination

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition significantly impacts plant functional traits in alpine meadows, yet the adaptive strategies of dominant species remain unclear. Understanding these strategies is crucial for predicting alpine grassland vegetation changes and ecosystem ...

Heterogeneous changes in global glacial lakes under coupled climate warming and glacier thinning

open access: yesCommunications Earth & Environment
Global glacial lakes have expanded markedly in recent decades, accompanied by many catastrophic glacial lake outburst floods. However, our understanding of glacial lake evolution and connections with global warming and glacier thinning remains ...

Soil pH thresholds mediate soil biodiversity by regulating interspecific associations in alpine wetlands of the Qinghai–Tibetan Plateau

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil pH is recognized as a major determinant of soil biodiversity. However, the extent to which soil pH regulates soil biodiversity by influencing the biotic associations among species is unclear.

From Nominalisation to Passive in Old Tibetan: Reconstructing Grammatical Meaning in an Extinct Language1

open access: yesTransactions of the Philological Society, EarlyView.
Abstract Based on an analysis of the Old Literary Tibetan corpus—a corpus of the oldest documented Tibetic language—the present study provides evidence that literary Tibetan v3 verb stems (commonly termed ‘future’) initially encoded passive voice. New arguments put forward in this article range from Trans‐Himalayan nominal morphology to early Tibetan ...

Spatio-temporally explicit reconstruction of upper range limit of trees since the LGM over the Tibetan Plateau

open access: yesScientific Data
Paleo-changes in upper range limit of trees provide a valuable analogue for understanding how high-elevational-trees may respond to future climate. Here, we presented a high-resolution (1 km) reconstruction of paleo-changes in the upper range limits of ...
