Structure of canopy and ground-dwelling arthropod communities in olive orchards is determined by the type of soil cover

The intensification of agriculture in olive groves, especially the modification or elimination spontaneous vegetation, alters relationships arthropod communities and reduces their interactions ecosystem services. This study was carried out nine groves which there either a planted cover crop, crop bare ground. ground-dwelling, canopy flying arthropods trophic webs were calculated for each grove soil management regime at family level taking into consideration different functional traits: feeding guilds, specific agricultural traits level. Olive with had higher number plausible links between families more balanced distribution specimens among levels compared to those There similar consisting both pests natural enemies regime, while ground simpler webs. complexity greater plant despite values richness three-olive regimes. Qualitative (such as traits) diverse agroecosystems sources food.
