Under a warming climate, degrading permafrost profoundly and extensively affects arctic
and alpine ecology. However, most existing relevant studies are more focused on the …

Where present, permafrost exerts a primary control on water fluxes, flowpaths, and
distribution. Climate warming and related drivers of soil thermal change are expected to …

As global temperatures rise, large amounts of carbon sequestered in permafrost are
becoming available for microbial degradation. Accurate prediction of carbon gas emissions …

Permafrost vulnerability to climate change may be underestimated unless effects of wildfire
are considered. Here we assess impacts of wildfire on soil thermal regime and rate of …

Terrestrial hydrology is central to the Arctic system and its freshwater circulation. Water
transport and water constituents vary, however, across a very diverse geography. In this …

Canadian boreal woodlands and forests cover approximately 3.09× 106 km2, located within
a larger boreal zone characterized by cool summers and long cold winters. Warming since …

It has been shown that reactive soil minerals, specifically iron (III)(oxyhydr) oxides, can trap
organic carbon in soils overlying intact permafrost, and may limit carbon mobilization and …

Permafrost contains about 50% of the global soil carbon. It is thought that the thawing of
permafrost can lead to a loss of soil carbon in the form of methane and carbon dioxide …

The term thermokarst describes the processes and landforms that involve collapse of the
land surface as a result of the melting of ground ice. We review the literature that has …

Abstract Ecosystems in the North American Arctic-Boreal Zone (ABZ) experience a diverse
set of disturbances associated with wildfire, permafrost dynamics, geomorphic processes …
