    The effects of earthworms on soil CH4 emissions remain ambiguous, as previous studies revealed both positive and negative effects on net rates of CH4 production. These differences may be linked to land-use history such as pasturing intensity, as the treading of livestock and the input of faeces will affect physical and chemical soil characteristics that are important to methanogenic and methanotrophic bacteria. In order to concomitantly measure the effects of earthworms on the activities of both of these bacterial groups, we performed an isotope dilution assay to measure gross CH4 production and consumption rates. Samples from three soil types, differing mainly in pasture intensity over the past 15 years, were incubated for 8 weeks in the presence or absence of the vermicomposting species Eisenia andrei.
