Provided that 13C natural abundance of earthworm tissues is determined by their diet, the assimilation of soil organic matter by earthworms was estimated by measuring 13C/12C ratio of tissues of earthworms sampled in soils containing organic pools with differing 13C/12C ratios. Earthworms were collected in two locations where the vegetation shifted from a C3 to a C4 type (France), or from a C4 to a C3 type (Ivory Coast) 3 to 20 years ago. The results show that irrespective of their ecology (litter or soil-feeding), earthworms mainly feed on recent soil organic pools and assimilate soil organic matter with the same age distribution as the overall decomposers in the soil.
