Ratios of C{sup 13}/C{sup 12} have been measured in methane from a variety of sources in tropical Kenya. Ranges of delta-C{sup 13} in CH{sub 4} for termites (most values range from {minus}56 to {minus}64{per thousand}, one is at {minus}44{per thousand}), one is at approximately {minus}73{per thousand}, rice paddies (range {minus}57 to {minus}63{per thousand}), and wetlands (range-45 to {minus}50{per thousand} for Lake Baringo, approximately {minus}55{per thousand} in the Moloi River, approximately {minus}62{per thousand} and approximately {minus}31{per thousand} in two swamp areas) are presented. The data are interpreted with the help of additional measurements of delta-C{sup 13} of CO{sub 2} 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. 40 refs., 2 figs. 5 tabs.
