The spatio-temporal structure of an earthworm community was assessed in a tropical Colombian pasture and compared with the patterns of soil heterogeneity. Earthworms were sampled at six dates during a period of one year, while soil properties were assessed at a single date at the end of this ...

In the Vertisols of Martinique, the effect of roots and organic materials seem predominant in soil structure development and earthworms play a secondary role. (2) Endogeic earthworm species have different effects on soil properties. Large earthworms such as or egest large and compact casts. They ...
sequence typing (MLST) approach onVerminephrobacterisolated from two contrasting ecological types of earthworm hosts: the high population density, fast reproducing compost worms,Eisenia andreiandEisenia fetida, and the low-density, slow reproducingAporrectodea tuberculata, commonly found in garden soils....
Agricultural intensification, soil biodiversity and agroecosystem function in the tropics: the role of earthworms Earthworm biodiversity is modified when forests and natural savannas are replaced by agroecosystems; these changes can be studied from the taxonomic and fu......
The taxonomic structure of earthworms of coffee plantations systems at three different places in Puerto Rico (Las Maras, Lares, and Jayuya), representing different soil types, was assessed. Organisms were manually sorted in a 0.25 m2, and various soil analyses were carried out. Eight earthworm ...
