The spatial distribution of seven earthworm species from the Lamto savannas (Côte d'Ivoire) was investigated by Taylor's Power Law. The method yielded aggregation indices highly correlated with species demographic and morphological parameters. A Principal Component Analysis showed that the smaller an earthworm species was and the higher its annual fecundity, the more its spatial distribution was aggregated. Mapping of some species density showed the diversity of spatial patterns in the field.
