Reproductive strategies of three native earthworm species from the savannas of Carimagua (Colombia)

Abstract

Some data on the reproductive biology of three native glossoscolecid species from the Colombian “Llanos” are presented. The seasonal dynamics of reproduction varied among the species considered which displayed either one or two reproductive periods per year. Cocoons were laicl at different depths to a maximum of 50 cm. The relation between cocoon weight and adult weight was the sanie for two endogeic species, ca. 6%, whereas for one anecic species the value has been the highest obtained to date for any tropical and temperate earthworm, i.e., 16 %.
