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.1 aVELASQUEZ, E.1 aDUBS, F.1 aGOND, V.1 aCELINI, L.1 aMATHIEU, J.1 aROULAND, C.1 aHARRY, M.  tIn: INTERNATIONAL COLLOQUIUM ON SOIL ZOOLOGY, 15; INTERNATIONAL COLLOQUIUM ON APTERYGOTA, 12., 2008, Curitiba.
