In this study, the effect of the soil dwelling earthworm Aporrectodea caliginoso and the woodlouse Porcellio scaber (litter inhabitant), atone or in combination, on soil aggregation was investigated in laboratory microcosms with litter of different quality (Quercus robur and Fagus sylvatica). After 4 months of incubation, the aggregate size distribution was measured using a dry-sieving method. A. caliginosa played an important role in the formation of large aggregates (> 2 mm), whereas P scaber greatly influenced litter disappearance. A. caliginosa individuals formed a greater number of large aggregates when fed with beech leaves compared to oak leaves even though they preferred the latter. In the presence of beech and P scaber, A. caliginosa produced significantly fewer large aggregates than expected. specialized soil dwelling invertebrates litter transformers litter palatability soil aggregation 074 021 51 5-6 439-443 2008 0031-4056 https://www.documentation.ird.fr/hor/fdi:010042565 10.1016/j.pedobi.2008.01.002 0031-4056 [F B010042565] https://www.documentation.ird.fr/hor/fdi:010042565 https://www.documentation.ird.fr/intranet/publi/2008/05/010042565.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-05-30 2017-08-23 fdi:010042565 fre
