The aim of this study was to evaluate the influence of land-use intensification on soil spider assemblages from six different land-use systems in Colombia and Brazil. The systems were fallows after crops and pastures, forest, crops, pastures and plantations. Spider species richness and density decreased with increasing farming management intensity. A principal component analysis (PCA) showed forests and fallows were separated from systems with stronger anthropogenic soil disturbance. The relationships of ten spider guilds differed significantly between land-uses, suggesting that they can be a reliable parameter for studies of ecological indicators. specialized Macroecology agroecosystems land-use guilds ecological indicators 074 082 076 39 2 296-302 2011 0161-8202 https://www.documentation.ird.fr/hor/fdi:010054190 0161-8202 [F B010054190] https://www.documentation.ird.fr/hor/fdi:010054190 https://www.documentation.ird.fr/intranet/publi/2011/12/010054190.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2012-01-10 2017-08-23 fdi:010054190 fre
