The structure and seasonal changes of earthworm communities were evaluated in a natural savanna and in a improved grass-legume pasture in a Colombian oxisol over a period of 18 months. One plot of 90×90 m was isolated in each of the systems and each month five samples of 1 m2×0.5 m and ten of 20×...

Earthworm communities in native savannas and man-made pastures of the Eastern Plains of Colombia
Martiodrilus carimaguensis (Oligochaeta, Glossoscolecidae) is a large, anecic native earthworm species which was found in natural and disturbed savannas in the Oxisols of the Colombian Llanos. The population dynamics of this species were studied in a native savanna, and in a 17-year-old grazed gr...

Population dynamics and adaptive strategies of Martiodrilus carimaguensis (oligochaeta, glossoscolecidae), a native species from the well-drained savannas of 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...

Tropical savannas constitute one of the most predominant ecosystems in South America with an overall extension of almost 250 millions ha. The role that these grasslands play over the environment is a key factor to understand its functioning and the response to changes induced by humankind. Moreov...
