Plant roots play a critical role in ecosystem function in arctic tundra, but root dynamics in
these ecosystems are poorly understood. To address this knowledge gap, we synthesized …

Terrestrial biosphere models (TBMs) have become an integral tool for extrapolating local
observations and understanding of land–atmosphere carbon exchange to larger regions …

The topics assessed in this chapter were last assessed by the IPCC in 2007, principally in
WGII AR4 Chapters 3 (Kundzewicz et al., 2007) and 4 (Fischlin et al., 2007), but also in WGII …

The Arctic is a water-rich region, with freshwater systems covering about 16% of the northern
permafrost landscape. Permafrost thaw creates new freshwater ecosystems, while at the …

The ecosystem approach to ecology treats organisms and the physical elements of their
environment as components of a single, integrated system. This comprehensive textbook …

As the permafrost region warms, its large organic carbon pool will be increasingly
vulnerable to decomposition, combustion, and hydrologic export. Models predict that some …

Although the flux of dissolved organic carbon (DOC) through freshwaters is nearly
equivalent to the net carbon uptake of all terrestrial ecosystems, uncertainty remains about …

This synthesis addresses the vulnerability of the North American high‐latitude soil organic
carbon (SOC) pool to climate change. Disturbances caused by climate warming in arctic …

This second edition brings this definitive book completely up to date with the many advances
in our understanding of Arctic climate since the first edition was published in 2005. The book …

Permafrost degradation may lead to mobilization of carbon and nutrients and enhance
microbial processing rates of previously frozen organic matter. Although the pool size and …
