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×...

This study was carried out in the Eastern Plains of Colombia and assessed the impact of agricultural intensification on the structure of earthworm communities. Earthworms were hand-sorted in a variety of agroecosystems of increasing intensity, from natural savanna to pastures and annual crops. An...


Decaëns, ThibaudJiménez Jaén, J.J.[Earthworm communities under an agricultural intensification gradient in Colombia]Earthworm communities under an agricultural intensification gradient in Colombia

In this study, we investigated the spatial distribution of an earthworm community together with the heterogeneity of selected soil properties in a gallery forest (GF) of the Colombian Llanos . We performed fine-scale spatial variability by intensively sampling 100 points distributed in the nodes...
