Percentage of atmospheric CH4 oxidised in the soil profile and statistical analysis of whole profile % CH4 oxidised for early, mid and late succession islands.

Model assumes transport of CH4 in to the soil by diffusion (α transport = 1.0195). The whole profile estimate considers the total CH4 oxidised for the given depths of humus. Values in brackets are standard errors of the mean. For early and mid islands ‘nd’ indicates where samples could not be obtained due to a shallow humus depth. The number of depths sampled is given by n. For whole profile analyses values followed by the same letter in subscript indicate no significant difference at P Percentage of atmospheric CH4 oxidised in the soil profile and statistical analysis of whole profile % CH4 oxidised for early, mid and late succession islands.
