Methane soil-vegetation-atmosphere fluxes in tropical ecosystems
(2007)
Recently, a surprising discovery indicated that, by an unknown process, vegetation emits methane to the atmosphere. This finding could have serious implications in atmospheric chemistry, climate, and mitigation of global ...
Afforested sites in a temperate grassland region: influence on soil properties and methane uptake
(Springer, 2018-04)
Methane (CH4) flux at the soil-atmosphere interface (SAI) results from the balance between CH4 production (methanogenesis) and CH4 consumption (methanotrophy). The latter predominates in well-aerated mineral soils; is ...
Enteric methane emissions by lactating and dry cows in the high Andes of Peru
(Springer NetherlandsNL, 2022-03-26)
The objective of the study was to determine enteric methane emissions using the sulfur hexafluoride (SF6) technique and comparing with The Intergovernmental Panel on Climate Change (IPCC) methodology in lactating cows (LC) ...
Methane oxidation and diffusivity in mollisols under an urban forest in Argentina
(Elsevier, 2019-09)
Methane (CH4) oxidation in aerated soils is regulated mainly by physical factors which limit CH4 diffusion into the soil. Using the static chamber technique, we measured CH4 flux at the soil-atmosphere interface (SAI) and ...
ENSO‐Influenced Drought Drives Methane Flux Dynamics in a Tropical Wet Forest Soil
(2019)
Global atmospheric methane growth rates have wildly fluctuated over the past three decades, which may be driven by the proportion of tropical land surface saturated by water. The El Niño/Southern Oscillation Event (ENSO) ...
Entrance dynamics of CH4 molecules through a methane-water interface
(Elsevier Science, 2015-09)
We studied the entrance mechanism of methane molecules into bulk water by Molecular Dynamics simulation over a broad time window. We corroborated that the presence of absorbed methane, under the studied thermodynamic state ...
Methane and carbon dioxide seasonal cycles at urban Brazilian inland sites
(Kluwer Academic Publ, 2004-02-01)
Methane and carbon dioxide seasonal cycles during years 1998 and 1999 at two Brazilian urban and inland sites are presented. The mixing ratio averages over the studied period of time were 1.80 ppm CH4 and 384.7 ppm CO2. A ...

Seasonal effect on feed intake and methane emissions of cow–calf systems on native grassland with variable herbage allowance
(Multidisciplinary Digital Publishing Institute, 2021-03)
The aim of this study was to measure methane emissions (CH4) and herbage intake, and, on the basis of these results, obtain the methane yield (MY, methane yield as g CH4/kg dry matter intake (DMI) and Ym, methane yield as ...
Elastic cross sections for low-energy e(-)-CH4 collisions
