[en] The study of soil arthropods can provide valuable information how ecosystems respond to different management practices. The objective was to assess the total abundance, richness, and composition of epiedaphic arthropods in different agrosystems from southwestern Spain. Six sites with different agricultural uses were selected: olive grove, vineyards, olive grove with vineyards, wheat fields, fallows (150-300 m long), and abandoned vineyards. Crops were managed in extensive. Field margins were used as reference habitats. At the seven sites a total of 30 pitfall traps were arranged in a 10 × 3 grid. Traps were arranged to short (SD, 1 m), medium (MD, 6 m) and large (LD, 11 m) distance to the field margins in the middle of selected plots. Pitfall traps captured a total of 11,992 edaphic arthropods belonging to 11 different taxa. Soil fauna was numerically dominated by Formicidae (26.60%), Coleoptera (19.77%), and Aranae (16.76%). The higher number of soil arthropods were captured in the field margins followed by the abandoned vineyard. Significant differences were found between sites for total abundance, and zones. However, no significant differences for total abundance were found between months (April-July). Richness and diversity was highest in field margins and abandoned vineyards. Significant differences were found for these variables between sites. Our results suggest that agricultural intensification affects soil arthropods in Tierra de Barros area, a taxonomic group with an important role in the functioning of agricultural ecosystems.

[es] El estudio de los artr&oacute;podos puede aportar informaci&oacute;n de inter&eacute;s de c&oacute;mo los ecosistemas responden a las diferentes pr&aacute;cticas de manejo del suelo. El objetivo de este estudio fue determinar la abundancia, la riqueza y la composici&oacute;n de artr&oacute;podos epigeos en diferentes agrosistemas del suroeste de Espa&ntilde;a. Se seleccionaron seis parcelas con diferentes usos agr&iacute;colas: olivar, vi&ntilde;edo, plantaci&oacute;n mixta de vi&ntilde;edo-olivar, cereal, barbecho y vi&ntilde;edo abandonado, utiliz&aacute;ndose los linderos como sistemas de referencia. En cada parcela se colocaron 30 trampas de ca&iacute;da en una cuadr&iacute;cula de 10 &times; 3, de modo que cada l&iacute;nea de trampas qued&oacute; colocada a una distancia corta (SD, 1 m), media (MD, 6 m) o grande (LD, 11 m) de los linderos. Se capturaron un total de 11.992 artr&oacute;podos ed&aacute;ficos, pertenecientes a 11 taxa diferentes. Num&eacute;ricamente la fauna del suelo estaba dominada por Formicidae (26,60%), Coleoptera (19,77%) y Aranae (16,76%). El mayor n&uacute;mero de artr&oacute;podos se captur&oacute; en los linderos y en la vi&ntilde;a abandonada, encontr&aacute;ndose diferencias significativas en la abundancia entre las diferentes parcelas y las zonas donde se ubicaron las l&iacute;neas de trampas. Sin embargo, no se encontraron diferencias entre los distintos meses estudiados (abril-julio). La riqueza y la diversidad fue mayor en los linderos y en la vi&ntilde;a abandonada, encontr&aacute;ndose diferencias entre parcelas para estas variables. Nuestros resultados sugieren que la intensificaci&oacute;n de la agricultura afecta a los artr&oacute;podos en Tierra de Barros, un grupo taxon&oacute;mico con un importante papel en el funcionamiento de los ecosistemas agr&iacute;colas.
