According to theory, the functional traits of species dictate how environmental selection
affects them, and also the functioning of ecosystems that those species form. However, we …

Permafrost peatlands in northern regions store a significant proportion of global soil carbon
and have historically played an important role in global carbon cycling. Recent warming is …

Tundra ecosystems are a globally important store of organic soil carbon (C) that is
vulnerable to greater microbial decomposition with warmer temperatures. The net C balance …

Terrestrial arctic ecosystems store large amounts of carbon (C). With global warming, this C
might be released into the atmosphere as CO2 by stimulation of soil microbial degradation …

Abstract Models are indispensable tools for projecting future permafrost extent and carbon
cycle. In this chapter the current state of the art in modelling is compared with the permafrost …

The release of carbon dioxide from Arctic permafrost soils is both a consequence and a
driver of the amplified increase of near-surface temperatures observed in the Arctic. The …

Abstract Retrogressive Thaw Slumps (RTSs)—a highly dynamic form of mass wasting, are
now exerting a dominant influence on geomorphic changes in the ice-cored terrain of the …

In recent years, polar regions have undergone the dramatic effects of global warming.
Determining the current composition of the microbial communities of these environments …

As the Arctic region continues to warm, permafrost melting contributes greenhouse gases to
the atmosphere by microbial digestion of soil organic carbon (SOC). While the permafrost …
