TL;DR: In this article, the effect of soil moisture on chamber measurements was tested by wetting the fine quartz sand to about 25% volumetric water content, and the results showed that the chamber headspace concentration also affects the flux by altering the concentration gradient between the soil and the chamber.

TL;DR: It seems that autochth onous and allochthonous carbon sources, which contribute to the CH(4) and CO(2) production in lakes, also have importance in the greenhouse gas emissions from reservoirs.

TL;DR: The authors showed that sediment respiration is one of the key factors contributing to the high CO2 supersaturation in and evasion from Finnish lakes, and evidently also over large areas in the boreal landscape, where the majority of the lakes are small and shallow.

TL;DR: In this article, the variability in concentrations of dissolved CH4 and annual flux estimates in the pelagic zone in a statistically defined sample of 207 lakes in Finland were explored, and they found that CH4 concentrations and fluxes to the atmosphere tended to be high in nutrient rich calcareous lakes, and that the shallow lakes had the greatest surface water concentrations.

TL;DR: It is found that the activity of methane-oxidizing bacteria provides not only carbon but also nitrogen to peat mosses and, thus, contributes to carbon and nitrogen accumulation in peatlands, which store approximately one-third of the global soil carbon pool.
