Earthworms are known to be good indicators of soil conditions, due to their susceptibility to management practices, vegetation types, disturbance, and other environmental properties. Little is known of the earthworm communities of Paraná State, Brazil, and therefore the present study was undertaken to evaluate the earthworm communities in Atlantic Rainforest fragments in the vicinity of Londrina, Paraná State, Brazil, and the effect of forest disturbance on their populations. Earthworms were sampled from three forest fragments at 1) the Godoy Forest State Park (GF); 2) the Arthur Thomas Municipal Park (AT); 3) the State University of Londrina (UEL) campus. GF is a moderately well preserved primary forest, AT is a secondary forest, at advanced level of succession, while UEL is a secondary forest at the incipient level of succession. Disturbance levels could thus be classified as UEL>AT>GF. Samples were taken in the wet and dry seasons (March and July) of 2005, and consisted 25 square soil blocks of 25 x 25 cm (1/16 m2), taken in a grid format, with 10 m distance between samples. Twenty samples were taken to 10 cm depth and five to 30 cm depth (diagonally in the grid). In the dry season, highest earthworm density was observed at AT (475 ind.m-2), followed by UEL (326 ind.m-2) and GF (24 ind.m-2). Earthworm biomass followed the order UEL (15.8 g.m-2) > AT (6 g.m-2) > GF (0.8 g.m-2). In the rainy season, highest populations were again observed at AT (1069 ind.m-2), followed by UEL (149 ind.m-2) and GF (139 ind.m-2). Earthworm biomass again followed the order UEL (23.1 g.m-2) > AT (18 g.m-2) > GF (3 g.m-2). Therefore, abundance and biomass were generally higher in the rainy season. Cocoon abundance and biomass was also greatest at all sites in the rainy season. In the dry season, more worms were found in the 20-30 cm layer compared to the top 10 cm, with the exception of the UEL forest. In the wet season, most earthworms inhabited the top 10 cm layer. Earthworm abundance was greater in the disturbed (UEL and AT) sites than the primary forest (GF). Species composition in the forests was also different. GF had only native earthworms (Urobenus brasiliensis, Urobenus sp. and Glossoscolex sp.), while both UEL and AT had both native (Urobenus brasiliensis, Fimoscolex sp., Glossoscolex sp., Belladrilus sp.) and exotic (Amynthas gracilis, Dichogaster spp. and Pontoscolex MenosEarthworms are known to be good indicators of soil conditions, due to their susceptibility to management practices, vegetation types, disturbance, and other environmental properties.
