Nitrogen deposition does not exacerbate phosphorus limitation of rhizosphere microbes in subalpine forests

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

Tourism in the Arctic is at risk due to intensifying permafrost degradation

Communications Earth & Environment
Climate change is destabilizing Arctic landscapes by accelerating permafrost degradation, leading to more frequent slope failures, especially during summers.

Review of Permafrost Degradation in the Mongolian Plateau

Land
Permafrost serves as a crucial indicator of global climate change. Its degradation significantly influences Earth’s surface systems, including hydrology, soil, climate, ecosystems, and even civil construction.

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

Archaeometry, EarlyView.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Permafrost degradation of peatlands in northern Sweden

, 2023
Abstract. Climate heating is degrading palsa peatlands across the circumpolar permafrost region. Permafrost degradation may lead to ecosystem collapse and potentially strong climate feedbacks, as this ecosystem is an important carbon store and can transition to being a strong methane emitter.

Ice-rich permafrost thaw under sub-aquatic conditions [PDF]

, 2017
Degradation of sub-aquatic permafrost can release large quantities of methane into the atmosphere, impact offshore drilling activities, and affect coastal erosion.

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Seismic Performance of Bridge Pile Foundation Considering Effects of Material Freeze-Thaw Deterioration and Permafrost Degradation

Zhongwai Gonglu
In cold and high-seismic regions, such as the Qinghai‒Xizang Plateau in China, the deterioration of material properties caused by freeze-thaw cycles and permafrost degradation due to climate change have become increasingly severe, posing significant ...

Thaw processes in ice-rich permafrost landscapes represented with laterally coupled tiles in a land surface model [PDF]

The Cryosphere, 2019
Earth system models (ESMs) are our primary tool for projecting future climate change, but their ability to represent small-scale land surface processes is currently limited.

Permafrost degradation stimulates carbon loss from experimentally warmed tundra [PDF]

Ecology, 2014
A large pool of organic carbon (C) has been accumulating in the Arctic for thousands of years because cold and waterlogged conditions have protected soil organic material from microbial decomposition. As the climate warms this vast and frozen C pool is at risk of being thawed, decomposed, and released to the atmosphere as greenhouse gasses. At the same
