TL;DR: In this paper, the authors report the range and statistical distribution of oxidation rates of atmospheric CH4 in soils found in Northern Europe in an international study, and compares them with published data for various other ecosystems.

TL;DR: In this article, static chamber measurements of CH4 flux were made from a range of micro-environments in an area of blanket bog in Northern Scotland, and investigations into the response of net CH4 emission rates to temperature and water table were carried out under semi-natural conditions on 45 large peat monoliths, maintained in open top chambers, over a three-year period.

TL;DR: In this article, the authors review methods of assessing carbon fluxes through termite populations and argue that direct measurements of net CO2 and CH4 emissions from termites in natural settings (in their nests or in the soil) are the best data for scaling-up calculations, if accompanied by accurate estimates of biomass and assemblage feeding-group composition.

TL;DR: In this article, seasonal variations in flux and the influence of atmospheric N inputs on the land atmosphere exchange of these two gases were investigated at upland moorland and coniferous forest sites in Southern Scotland.

TL;DR: Soil N2O emissions were measured from a range of mineral soils supporting woodlands, grassland and agriculture between 1991 and 1996 and were co-analysed in order to establish some overriding relationships between the N 2O emission and soil temperature, water content, available NH+4 and NO-3, pH and N input by fertiliser, manure and atmospheric deposition.
