Conteúdo: 	In three landscape windows representing different uses of the Amazon forest, soil macrofauna
was sampled at 16 points displayed every 200m on a regular grid. At each of the 48 points we
measured macroinvertebrate abundance and species richness in 15 Orders and assessed soil
macro aggregation. Landscape composition and structure were quantified by analysing landscape
maps with the FRAGSTAT programme. Significant co inertia was observed among landscape
variables and species richness in groups. Ants and Coleoptera showed increased species
richness in deforested and highly fragmented areas whereas termites and most litter dwelling
arthropods (Myriapoda, Isopoda) exhibited opposite patterns. Another significant co inercia
was observed among macro invertebrate communities and soil aggregation. This suggests
that changes in landscape affect soil structure and functions associated to this attribute through
changes in macroinvertebrate communities.
