  abstract = {{E}cological and demographic parameters of 26 species of native and exotic earthworms species common in tropical agroecosystems, with large environmental tolerance and/or extended distribution were investigated. {P}rincipal component analysis ({PCA}) isolated four groups : (i) large native endogeic and anecic species (16-32 g individual fresh wt) with long generation time (2-4 years), low fecundity (0.5-3.1 cocoons/year/adult) and one hatchling per cocoon ; (ii) medium size species (1.2-6 g) endogeic mesohumic, with intermediate fecundity (1.3-45 cocoons/year/adult) ; (iii) small species (0.17-1.25 g f.w.) mainly endogeic polyhumic, with short generation time (3-7 months), intermediate fecundity (10-68 cocoons/year/adult) and one hatchling per cocoon ; and (iv) generally small (80-150 mg f.w.) species mainly exotic and epigeic, with short generation time (1-3 months), very high fecundity (50-350 cocoons/year/adult) and up to three hatchlings per cocoon. {C}asts may be either large globular or small granular. {T}he selective investigations of large organic particles and small mineral particles (clays) concentrates total organic matter in the casts. {T}here is an intense mineralization rate of nitrogen in the casts (6-29% of organic {N}), exotic worms seeming to be less efficient than natives at mineralizing {N}. {T}he mineral phosphorus content of casts is always at least 30% higher than in the non-ingested soil. {A}ll these worms ingest daily, on average, three times their own weight of soil at the adult stage (1-9) and much more when juvenile ; up to 1000 {M}g dry soil/ha may transit yearly through earthworm guts.
