The effects of Martiodrilus carimaguensis (Oligochaeta, Glossoscolecidae) on soil seed banks was investigated in a Colombian savanna and two introduced pastures. Germination and washing-sieving methods were used to compare seed density, diversity, and germination rates in earthworm casts and the ...

El arado natural: las comunidades de macroinvertebrados del suelo en las sabanas neotropicales de Colombia
This was especially due to the presence of a large glossoscolecid anecic species, Martiodrilus carimaguensis Jim\233nez and Moreno, which has been greatly favored by conversion of savanna to pasture. Endogeic species were dominant in the natural savanna whereas the anecic species accounted for th...

Earthworms communities in native savannas and man-made pastures of the Eastern plains of Colombia
A detailed description and drawings of the aestivation chambers of five earthworm species are given plus a complete analysis of the mechanistic processes that determine this behavioral pattern for one anecic species from Colombia. The onset of aestivation differed in adults and juveniles for two ...
