Permafrost is a distinct feature of the terrestrial Arctic and is vulnerable to climate warming.
Permafrost degrades in different ways, including deepening of a seasonally unfrozen …

Organic matter (OM) refers to the largest reactive reservoir of carbon-based compounds on
Earth. Aside of its role as a source of carbon, OM is also actively involved in a wide range of …

Climate change induced permafrost thaw in the Arctic is mobilizing ancient dissolved
organic carbon (DOC) into headwater streams; however, DOC exported from the mouth of …

Northern high-latitude rivers are major conduits of carbon from land to coastal seas and the
Arctic Ocean. Arctic warming is promoting terrestrial permafrost thaw and shifting hydrologic …

CO2 emissions from inland surface waters to the atmosphere are almost as large as the net
carbon transfer from the atmosphere to Earth's land surface. This large flux is supported by …

New conceptual models that highlight the importance of environmental, rather than
molecular, controls on soil organic matter affect interpretations of organic matter (OM) …

The incomplete combustion of organic molecules produces a chemically diverse suite of
pyrogenic residues termed black carbon (BC). The significance of BC cycling on land has …

Riverine dissolved organic carbon (DOC) exerts a vital role in the global carbon cycle.
Although substantial studies have explored DOC dynamics in aquatic ecosystems, it …

Arctic warming is causing ancient perennially frozen ground (permafrost) to thaw, resulting
in ground collapse, and reshaping of landscapes. This threatens Arctic peoples' …

The dazzling variation in plant chemistry is a primary mediator of trophic interactions,
including herbivory, predation, parasitism, and disease. At the same time, such interactions …
