Gas exchange between soil and atmosphere represents a major component of global
greenhouse gas fluxes. Chamber methods and micro-meteorological methods are well …

It is widely recognized that forest soils are important terrestrial sinks for atmospheric CH 4;
however, the complexity of the underlying microbial production and oxidation processes …

Recent warming in the Arctic, which has been amplified during the winter 1, 2, 3, greatly
enhances microbial decomposition of soil organic matter and subsequent release of carbon …

Methane (CH 4) emissions from the northern high‐latitude region represent potentially
significant biogeochemical feedbacks to the climate system. We compiled a database of …

Besides water vapour, greenhouse gases CO2, CH4, O3 and N2O contribute~ 60%, 20%,
10% and 6% to global warming, respectively; minor contribution is made by …

Soil respiration (ie from soils and roots) provides one of the largest global fluxes of carbon
dioxide (CO2) to the atmosphere and is likely to increase with warming, yet the magnitude of …

Wetlands are the world's largest natural source of methane, a powerful greenhouse gas. The
strong sensitivity of methane emissions to environmental factors such as soil temperature …

Abstract Nine years (2003–2011) of carbon dioxide (CO2) flux were measured at a black
spruce forest in interior Alaska using the eddy covariance method. Seasonal and …

Boreal ecosystems store 10–20% of global soil carbon and may warm by 4–7° C over the
next century. Higher temperatures could increase the activity of boreal decomposers and …

Wetland CH 4 emissions are among the most uncertain components of the global CH 4
budget. The complex nature of wetland CH 4 processes makes it challenging to identify …
