Tundra vegetation change and impacts on permafrost
Tundra vegetation productivity and composition are responding rapidly to climatic changes
in the Arctic. These changes can, in turn, mitigate or amplify permafrost thaw. In this Review …

Pan-Arctic ice-wedge degradation in warming permafrost and its influence on tundra hydrology
Ice wedges are common features of the subsurface in permafrost regions. They develop by
repeated frost cracking and ice vein growth over hundreds to thousands of years. Ice-wedge …

Pan‐Arctic soil moisture control on tundra carbon sequestration and plant productivity
Long‐term atmospheric CO2 concentration records have suggested a reduction in the
positive effect of warming on high‐latitude carbon uptake since the 1990s. A variety of …

Climate‐driven vegetation greening further reduces water availability in drylands
Climate change alters surface water availability (WA; precipitation minus evapotranspiration,
P− ET) and consequently impacts agricultural production and societal water needs, leading …

Vegetation type is an important predictor of the arctic summer land surface energy budget
Despite the importance of high-latitude surface energy budgets (SEBs) for land-climate
interactions in the rapidly changing Arctic, uncertainties in their prediction persist. Here, we …

Landscape topography structures the soil microbiome in arctic polygonal tundra
In the Arctic, environmental factors governing microbial degradation of soil carbon (C) in
active layer and permafrost are poorly understood. Here we determined the functional …

Disappearing Arctic tundra ponds: Fine‐scale analysis of surface hydrology in drained thaw lake basins over a 65 year period (1948–2013)
Long‐term fine‐scale dynamics of surface hydrology in Arctic tundra ponds (less than 1 ha)
are largely unknown; however, these small water bodies may contribute substantially to …

Polygonal tundra geomorphological change in response to warming alters future CO2 and CH4 flux on the Barrow Peninsula
The landscape of the Barrow Peninsula in northern Alaska is thought to have formed over
centuries to millennia, and is now dominated by ice‐wedge polygonal tundra that spans …
