Tyler SC, Zimmerman PR, Cumberbatch C, Greenberg JP, Westberg C, Darlington JP: Measurements and interpretation of d13C of methane from termites, rice paddies, and wetlands in Kenya. Glob Biogeochem Cy 1988, 2:341-355.
Ratios of 13C/12C have been measured in methane from a variety of sources in tropical Kenya. Ranges of δ13C in CH4 for termites (most values range from −56 to −64‰, one is at −44‰ one is at ∼−73‰), rice paddies (range −57 to −63‰), and wetlands (range −45 to − 50‰ for Lake Baringo, ∼−55‰ in the Moloi River, ∼−62‰ and ∼−31‰ in two swamp areas) are presented. The data are interpreted with the help of additional measurements of δ13C of CO2 gas, and organic carbon in plant material, termite bodies, and termite fungus combs. The implications of these findings are related to the problem of studying the atmospheric methane budget.
