Earthworm burrow systems are generally described based on postulated behaviours associated with the three ecological types. In this study, we used X-ray tomography to obtain 3D information on the burrowing behaviour of six very common anecic (Aporrectodea nocturna and Lumbricus terrestris) and endogeic (Aporrectodea rosea, Allolobophora chlorotica,(More)
Soil compaction has a negative impact on both earthworm abundance and diversity. Recent studies, however, suggest that earthworm cast properties are not influenced by the initial soil bulk density. With time, earthworms could therefore transform soils with different bulk densities into a soil with the same physical state and thus with a similar ecological(More)
Earthworm casts weathered by rainfall are difficult to differentiate from surrounding soil aggregates. We tested the hypothesis that morphological characterisation of soil aggregates by 2D-image analysis helps to perform this differentiation. Compact surface casts produced by Amynthas khami and surrounding aggregates lacking visible signs of biological(More)
