Little information is avaliable on earthworm populations and biodiversity in the State of Paraná, southern Brazil, where most of the native vegetation (predominantly Atlantic Forest) was transformed into agroecosystems over the last 50 years. In the present study, earthworm biodiversity was evaluated in various land use systems near Jaguapitã, Paraná, where pastures predominated. Samples were taken during the rainy and dry seasons of 2004 and 2005. Seven sites were sampled: old pastures (n = 2), newly established soybean (n = 2) and sugarcane (n = 2) fields and a native forest (secondary) fragment (n = 1). Twentyfive samples (25 × 25 cm soil blocks) were taken at each site using a grid pattern; 20 samples to a depth of 10 cm, and five up to 30 cm depth, located on the diagonal of the grid. Earthworms were manually sorted from the soil and preserved in formaldehyde (4%). Fourteen earthworm species were found: the exotics Pontoscolex corethrurus (Glossoscolecidae) (the dominant species), Dichogaster affinis, D. bolaui and D. saliens (Acanthodrilidae), E. saltensis and Ocnerodrilus occidentalis (Ocnerodrilidae), and Amynthas sp. (Megascolecidae) (aclitellate sub-adult); the native species Glossoscolex n. sp. and Fimoscolex n. sp. (Glossoscolecidae), Eukerria eiseniana, Belladrilus n. sp.1 and an unidentifiable Ocnerodrilidade n. sp.1 (probably a Belladrilus sp.), as well as two unidentified Eukerria spp. (of unknown origin) (all of the Ocnerodrilidae family). The study revealed that some native earthworm species can be maintained, even in degraded pastures, but that exotics tend to predominate. This is particularly the case in cultivated agroecosystems and degraded forests, where both earthworm abundance and species diversity tend to be lower than in pastures.
