TL;DR: In this paper, the authors measured annual methane emission from a boreal minerotrophic fen, Siikaneva, by the eddy covariance method and found that over 20% of the carbon assimilated during the year as carbon dioxide was emitted as methane.

TL;DR: In this article, the variability in carbon gas exchange at the plant community scale affected the C gas exchange estimates at the ecosystem scale in a fen that was homogeneous in a micrometeorological sense, that is, had an even surface topography and plant cover.

TL;DR: In this paper, the authors investigated the hydrometeorological responses of CO 2 exchange during a drought period in July 2005, and concluded that this was mainly due to increased respiration, but evidence was also found of suppressed photosynthesis due to a high VPD.

TL;DR: In this article, emissions of various C2-C10 hydrocarbons (VOCs) and halogenated HOCs from a boreal wetland and a Scots pine forest floor in south-western Finland were measured by the static chamber technique.

TL;DR: In this article, the authors compared the N 2 O fluxes obtained from both static chamber and eddy covariance (EC) measurements for a year using the static chamber method based on a gas chromatograph (GC) and the EC technique based on tunable diode laser (TDL).
