Ecological preferences of some earthworm species in southwest Spain

A total of 80 samples were taken from three SW provinces of Spain (Cلceres, Badajoz and Huelva), from which 28 earthworm species were collected and 22 soil factors analyzed. The zone studied has a continental climate with scarce rainfall, high temperatures during the summer months and Mediterranean vegetation. ting to characterize the ecological preferences of those species present in more than 5% of the samples, we used the technique of ecological profiles, to point out speciesʹ preferences for such factors.
