Predicting Methane Production in Dairy Cows [PDF]

open access: yes, 2013
Methane is a potent greenhouse gas, to which enteric fermentation from ruminants contributes significantly. Reliable and accurate predictions of methane (CH₄) production from dairy cows would be of interest to develop mitigation strategies and for national inventories.

A decision support tool for landfill methane generation [PDF]

open access: yes, 2013
This paper focuses on providing a decision support tool (DST) to enhance methane generation at individual landfill sites. To date there is no decision support tool (DST) available to provide landfill decision makers with clear and simplified ...

Quantification of methane oxidation in the rice rhizosphere using 13C-labelled methane [PDF]

open access: yes, 1994
In this paper isotope ratio mass spectrometry is used to determine the methane (CH4) oxidation fraction in the rhizosphere of intact rice plant-soil systems.

Methane oxidation and emission in Lake Lugano (Southern Switzerland) : a lipid biomarker and isotopic approach [PDF]

open access: yes, 2015
Methane is an important greenhouse gas in Earth's atmosphere. The sources of atmospheric methane are largely biogenic, being produced under anoxic conditions by methanogenic Archaea.

THE USE OF PRIN IPAL COMPONENT ANALYSIS IN IDENTIFYING AND INTEGRATING VARIABLES RELATED TO FORAGE QUALITY AND METHANE PRODU TION [PDF]

open access: yes, 2009
This research was aimed to explore the use of multivariate statistics i.e.principal component analysis (PCA)in identifying and integrating variables related to forage quality and ruminal methane production,and in classifying forage species into both ...

Carbohydrate Type and Level Affect in Vitro Methane Production from Cecal Contents of White Roman Geese [PDF]

open access: yesBrazilian Journal of Poultry Science
The type of carbohydrate diet is an important factor in methane (CH4) emission from livestock. In this study, a structural carbohydrate (rice hull) was tested as a feed ingredient and compared with the use of a non-structural carbohydrate supplemented to

Attribution of production-stage methane emissions to assess spatial variability in the climate intensity of US natural gas consumption

open access: yesEnvironmental Research Letters, 2021
Although natural gas is often viewed as a commodity fuel with limited variability due to standardization for pipeline transportation, life cycle impacts of natural gas vary substantially.

Upscaling methane emissions from rice paddies: problems and possibilities. [PDF]

open access: yes, 2002
Global methane emission estimates depend highly on the models, techniques, and databases used. Since emissions cannot be measured directly at large scales, it is impossible to judge which estimate is more realistic.
