Scaling methane emissions from vegetation
Trends in Ecology & Evolution, 2006In a recent highly publicised paper, Keppler et al. [1] report the remarkable observation that methane is emitted directly by plants, and in an aerobic environment. Previously, emissions from vegetation were attributed to anaerobic microbial associations (e.g. in water-logged soils).

Methane emissions from natural wetlands
Environmental Monitoring and Assessment, 1996Methane is considered one of the most important greenhouse gases in the atmosphere. Because of the strict anaerobic conditions required by CH4-generating microorganisms, natural wetland ecosystems are one of the main sources of biogenic CH4. The total natural wetland area is estimated to be 5.3 to 5.7 × 10(12) m(2), making up less than 5% of the Earth ...

The atmospheric concentration of methane has increased rapidly in recent years. Because it is a radiative trace gas and takes part in atmospheric chemistry, the rapid increase could be of significant environmental consequence. Of the wide variety of sources, rice fields are considered an important source of atmospheric methane because the harvest area ...

C&EN Global Enterprise, 2016
In a move to slash U.S. greenhouse gas emissions, EPA on May 12 issued its first-ever regulations to reduce methane releases by the oil and natural gas sector. The regulations apply to new, modified, and reconstructed oil and gas operations. Similar rules for millions of existing oil and gas drilling and production facilities are on hold as the agency ...

Small Ruminant Research, 1998
Abstract A total of 1137 observations from sheep of different age fed with rations of different composition were collected from the literature. This study used measures of methane emissions from sheep under different feeding conditions to compute regression equations to predict methane emissions from ration descriptive variables.

Nitrogen Application Stimulates Methane Emissions
Global Change BiologyNitrogen fertilizer plays a vital role in rice cultivation, yet its excessive application significantly intensifies methane emissions from rice paddies. Therefore, the urgent adoption of effective agronomic interventions is crucial to mitigate methane emissions resulting from nitrogen fertilizer application.

Estimating landfill methane emissions
Energy Conversion and Management, 1996Landfill methane emissions, estimated to be around 2 million tonnes in 1990, represent a significant but highly uncertain proportion of the UK's releases of methane to the atmosphere. The mass and rate of methane emissions depends on many factors that are difficult to quantity and vary from site to site.

Methane Emissions and Ruminants
Microbe Magazine, 2009It was with great interest that I discovered the recent article entitled “Metabolic Teamwork between Gut Microbes and Hosts” in the July 2009 issue of Microbe (p. 323). Microbiologists, like myself, who work with gastrointestinal tract anaerobes are always interested in seeing this area of science highlighted in publications such as Microbe. Thanks for
