Selected papers.  aLand use changes in the Amazon region strongly impact soil macroinvertebrate communities, whichare recognized as major drivers of soil functions (Lavelle et al., 2006). To explore these relations, wetested the hypotheses that (i) soil macrofauna communities respond to landscape changes and (ii) soilmacrofauna and ecosystem services are linked. We conducted a survey of macrofauna communities andindicators of ecosystem services at 270 sites in southern Colombia (department of Caqueta) and north-ern Brazil (state of Pará), two areas of the Amazon where family agriculture dominates. Sites representeda variety of land use types: forests, fallows, annual or perennial crops, and pastures. At each site weassessed soil macroinvertebrate density (18 taxonomic units) and the following ecosystem service indi-cators: soil and aboveground biomass carbon stock; water infiltration rate; aeration, drainage and waterstorage capacities based on pore-size distribution; soil chemical fertility; and soil aggregation. Signifi-cant covariation was observed between macrofauna communities and landscape metric data (co-inertiaanalysis: RV = 0.30, p &lt 0.01, Monte Carlo test) and between macrofauna communities and ecosystemservice indicators (co-inertia analysis: RV = 0.35, p &lt 0.01, Monte Carlo test). Points located in pastureswithin 100 m of forest had greater macrofauna density and diversity than those located in pastures withno forest within 100 m (Wilcoxon rank sum test, p &lt 0.01). Total macroinvertebrate density was signifi-cantly correlated with macroporosity (r2= 0.42, p &lt 0.01), as was the density of specific taxonomic groups:Chilopoda (r2= 0.43, p &lt 0.01), Isoptera (r2= 0.30, p &lt 0.01), Diplopoda (r2= 0.31, p &lt 0.01), and Formicidae(r2= 0.13, p &lt 0.01). Total macroinvertebrate density was also significantly correlated with available soilwater (r2= 0.38, p &lt 0.01) as well as other soil-service indicators (but with r2&lt 0.10). Results demonstratethat landscape dynamics and composition affect soil macrofauna communities, and that soil macro-fauna density is significantly correlated with soil services in deforested Amazonia, indicating that soilmacrofauna have an engineering and/or indicator function.  aAmazonia  aEcossistema  aLandscape  aMacro-invertebrates  aMacroinvertebrado  aPaisagem deflorestada  aSoil services1 aGRIMALDI, M.1 aFEIJOO M.
