Scaling methane emissions from vegetation

Trends in Ecology & Evolution, 2006
In 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 MBT landfills

Waste Management, 2013
Within the scope of an investigation for the German Federal Environment Agency ("Umweltbundesamt"), the basics for the estimation of the methane emissions from the landfilling of mechanically and biologically treated waste (MBT) were developed. For this purpose, topical research including monitoring results regarding the gas balance at MBT landfills ...

Methane and nitrous oxide emissions: an introduction

Fertilizer Research, 1994
Methane and nitrous oxide are important greenhouse gases. They contribute to global warming. To a large extent, emissions of methane and nitrous oxide are connected with the intensification of food production. Therefore, feeding a growing world population and at the same time controlling these emissions is a great challenge.

Methane Emissions and Ruminants

Microbe Magazine, 2009
It 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

Methane emissions from natural wetlands

Environmental Monitoring and Assessment, 1996
Methane 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 ...

Methane emission of the Amsterdam urban area

1995
Within the Dutch National Research Programme on Climate Change, the emission of methane from urban areas was considered to be one of the uncertain sources in the national methane budget. Amsterdam was chosen to be the urban area for methane emission assessment. An emission inventory was made and concentration fields were calculated using the Danish OML

Methane Emissions from the Amazon Floodplain

1997
Methane (CH4) is an important greenhouse gas that also affects the chemistry and oxidation capacity of the atmosphere (Cicerone and Oremland 1988). The current burden of methane in the atmosphere is about 4700Tg (1 Tg =1 million tons) (Wahlen et al. 1989), and the global annual emission is ca. 505 Tg CH4 year−1 (Crutzen 1991). Ca.
