Thermal effect of thermokarst lake on the permafrost under embankment

Advances in Climate Change Research, 2021
In permafrost regions of the Qinghai-Tibet Plateau, road disaster caused by permafrost degradation cannot be ignored. As a common thermal disaster in permafrost regions, thermokarst lake has serious thermal erosion on permafrost and results in permafrost

The rise and fall of a volcanic plateau: Landscape evolution at the fringes of the former Patagonian Ice Sheet, Meseta Chile Chico, central Patagonian Andes

Journal of Quaternary Science, EarlyView.
ABSTRACT Understanding Earth‐surface processes along the fringes of large ice sheets is integral to deciphering cold‐region environmental variability and anticipating slope instability under climate change. We investigate the Meseta Chile Chico, a volcanic plateau in the central Patagonian Andes, located at the eastern margin of the former Patagonian ...

Sensitivity of the impact of aeolian sand cover on permafrost degradation in the Qinghai–Xizang Plateau

Environmental Research Letters
Environmental transformations and intensifying desertification across the Qinghai–Xizang Plateau (QXP) are having a significant influence permafrost degradation, heightening the risks associated with carbon emissions, thermal hazards and infrastructural ...

Quaternary Permafrost in China: Framework and Discussions

Quaternary, 2020
The framework of Quaternary permafrost in China was reconstructed for the first time on the basis of available periglacial, glacial, and other proxies. During the Early Pleistocene (2.68–0.80 Ma BP), permafrost advanced southwards to 47–50° N in northern

Cutting through the noise: What can habitat selection modeling teach us about caribou‐fire space use dynamics?

The Journal of Wildlife Management, EarlyView.
We synthesize the current knowledge regarding caribou habitat selection in relation to wildfires. Caribou responses to recent burns were generally weak and highly variable across subspecies or ecotypes, suggesting that post‐fire habitat selection is likely context‐dependent and the need for regionally adapted habitat management strategies.

Research progress and perspectives on ecological processes and carbon feedback in permafrost wetlands under changing climate conditions

Fundamental Research
Permafrost wetlands are closely related to potential greenhouse gas emissions under climate warming. In recent decades, climate change and human activities have induced extensive permafrost degradation, severely influencing the stability of wetlands in ...

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Microbial communities in submarine permafrost and their response to permafrost degradation and warming [PDF]

, 2020
The Arctic region is especially impacted by global warming as temperatures in high latitude regions have increased and are predicted to further rise at levels above the global average. This is crucial to Arctic soils and the shallow shelves of the Arctic Ocean as they are underlain by permafrost.

A Generic Approach to Creating a National Soil Security Strategy

Sustainable Development, EarlyView.
ABSTRACT Soil is a living and non‐renewable resource that underpins our very existence. It produces our food, filters our water, stores vast amounts of carbon, cycles essential nutrients, and sustains the rich tapestry of biodiversity on which our planet depends.

Banking Biodiversity: Ex Vivo Solutions for a Planet in Crisis

Zoo Biology, EarlyView.
Genetic diversity is being lost faster than it can be cataloged. Biobanking preserves cells, gametes, and DNA as recoverable material for future conservation use, and delivers most when collections are established proactively rather than deployed once populations are already critically depleted.
