Resumen

The earthworm community in El Molar (Madrid) is studied, and its distribution
patterns and relation with some soil factors are described by using geostatistic and
multivariate tools. Six species were found, Hormogaster elisae, Allolobophora rosea
and Allolobophora caliginosa being the three most abundant ones. These species
exhibited a clumped distribution. The most dominant species, H. elisae, was
distributed in patches of an average size of 45m in spring and more than 100m in
autumn. A. rosea was aggregated in patches of an average size of 22m and
A. caliginosa formed patches of an average size of 38 m. There seemed to be a
positive correlation between the abundance of H. elisae and the percentage of total
and coarse sands, as well as a negative correlation with clay, nitrogen, carbon and
coarse loams contents, opposite to what was observed for A. rosea.
