Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A New Method of Diagnosing the Historical and Projected Changes in Permafrost on the Tibetan Plateau

open access: yesEarth's Future
The Tibetan Plateau (TP) is the largest permafrost distribution zone at high‐altitude in the mid‐latitude region. Climate change has caused significant permafrost degradation on the TP, which has important impacts for the eco‐hydrological processes.

The Mesozoic along-strike tectono-metamorphic segmentation of Longmen Shan (eastern Tibetan plateau) [PDF]

open access: yes, 2018
The Longmen Shan belt (eastern border of the Tibetan plateau) constitutes a tectonically active region as demonstrated by the occurrence of the unexpected 2008 Mw 7.9 Wenchuan and 2013 Mw 6.6 Lushan earthquakes in the central and southern parts of the ...

Adaptive Genomic Divergence Across Altitudes in Capsella bursa‐pastoris

open access: yesBiological Diversity, EarlyView.
Genomic divergence was observed between high‐altitude and low‐altitude populations of Capsella bursa‐pastoris in China, consistent with an important role of ecological factors. Candidate adaptive loci associated with enhanced energy metabolism, photoprotection, and growth plasticity under altitudinal stress were identified.

Importance of fluvial inflows in the intra-lake heterogeneity of surface water temperatures on the Tibetan Plateau

open access: yesnpj Climate and Atmospheric Science
Lakes on the Tibetan Plateau (TP) are highly responsive to environmental change. Spatiotemporal variations in the lake surface water temperature (LSWT) significantly impact regional ecosystem stability, carbon cycling, and regional climate.

Paleomagnetism From Central Iran Reveals Arabia‐Eurasia Collision Onset at the Eocene/Oligocene Boundary

open access: yesGeophysical Research Letters, 2023
We present two robust and well‐dated paleomagnetic poles from upper Eocene and Oligocene volcanics in the Urumieh‐Dokhtar magmatic arc, Central Iran. These two poles place Iran ∼3.7°–3° of latitude south of its present position between ca.

Seismic analysis and design of tunnels within fault ground: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
The research methods of seismic response of tunnels within fault ground, including field investigations, analytical solutions, physical experiments, and numerical simulations, and seismic countermeasures are discussed. The present study examines the shortcomings and limitations of the current research and design, and puts forward proposals for future ...

Functional group and aridity regulate impacts of climate change on plant phenology: a meta-analysis

open access: yesNature Communications
The interaction between temperature and precipitation greatly affects plant phenology. However, these effects can vary between additive, antagonistic, and synergistic, and it is not clear what determines these different outcomes.

Sino-Tibetan languages [PDF]

open access: yes, 2010
The Sino-Tibetan (ST) language family includes the Sinitic languages (what for political reasons are known as Chinese ‘dialects’) and the 200 to 300 Tibeto-Burman (TB) languages.

Selection and environmental adaptation along a path to speciation in the Tibetan frog Nanorana parkeri. [PDF]

open access: yes, 2018
Tibetan frogs, Nanorana parkeri, are differentiated genetically but not morphologically along geographical and elevational gradients in a challenging environment, presenting a unique opportunity to investigate processes leading to speciation. Analyses of
