“…Selection of landscape circles was furthermore based on the type of habitat bordering the focal field of each circle, such that we would have six replicate landscape circles for each of three types of adjacent habitat: crop field, linear herbaceous SNH or linear woody SNH. The study site selection (Section 2.1), landscape description and classification of SNHs (Section 2.2), and experimental design (Section 2.3) were based on standardized protocols of the EU FP7 project QuESSA across participating regions and crops …”

“…Reliance on specific land cover types has also been seen recently in orchard systems where spider and pest fly abundance was altered by Mediterranean garigue and woody areas, respectively, in the surrounding landscapes (Picchi et al . ). Other highly disturbed land cover types such as pasture, soybean, and tobacco; and densely wooded covers like deciduous and evergreen forest had negative relationships with both ants and pests.…”

Land cover diversity increases predator aggregation and consumption of prey

A lower diversity of land cover types is purported to decrease arthropod diversity in agroecosystems and is dependent on patterns of land use and fragmentation. Ants, important providers of ecosystem services such as biological control, are susceptible to landscape-level changes. We determined the relationships between land cover diversity and fragmentation on the within-field spatial associations of ants to pests and resulting predation events by combining mapping and molecular tools. Increased land cover diversity and decreased fragmentation increased ant abundance, spatial association to pests and predation. Land cover diversity and fragmentation were more explanatory than land cover types. Even so, specific land cover types, such as deciduous forest, influenced ant and pest diversity more so than abundance. These results indicate that geospatial techniques and molecular gut content analysis can be combined to determine the role of land use in influencing predator-prey interactions and resulting predation events in agroecosystems.

“…Nave et al . () have reported the beneficial effects of presence of native Mediterranean plants for natural enemies of olive pest, and other studies have demonstrated the positive effects of cover in olive crop on specific entomophagous insects taxa as spiders (Picchi et al ., ), carabids (Dinis, ) and green lacewings (Porcel et al ., ).…”

“…entomofauna) maintain close relationships and connections with the surrounding area and landscape (Madeira et al ., ). These influences of external environment have been studied in several arthropods taxa, such as hymenopterans (Pascual et al ., ), coccinellids (Smith et al ., ), spiders and olive fruit flies (Picchi et al ., ), as well as other ground‐dwelling arthropods (Fox et al ., ). The heterogeneous surrounding area and landscape provide a reduction of wind speed, an improvement of the flying distance of insects (Smith & Lewis, ), a refuge from high temperatures (Gareau et al ., ) and shelter for many taxa that serve as prey for predaceous arthropods (Picchi et al ., ).…”

Farmers in Europe who subscribe to organic agriculture have greatly increased weed cover and diversity by not using synthetic fertilizers and pesticides (Bengtsson et al ., ), although the most extended production system still comprises a classical system in which herbicides are commonly used to prevent weeds.…”

1 Agricultural intensification has greatly affected biodiversity in recent decades. One common and recent transformation that has taken place in Mediterranean countries is olive grove intensification, although its effects on biodiversity have rarely been studied. 2 In the present study, we investigated the effect of soil management practices, with versus without soil cover crops, on the arthropod abundance, richness, diversity and species composition in Andalusia olive groves, South Spain. 3 The results obtained show that these soil cover crops positively affect the diversity of arthropods, along with other variables such as the diversity of the plant community and Shannon index of the landscape. By contrast, the number of arthropods was higher in olive groves with bare ground as a result of the abundance of two families (Entomobryidae and Aeolothripidae), which comprised more than 50% of all the individuals collected. 4 Rank abundance diagrams and multivariate analyses showed differences between the two types of soil management systems with respect to the composition of families. 5 In conclusion, soil cover crops strongly improve the diversity of arthropods in olive orchards, which helps to maintain biodiversity in these intensive agroecosystems at the same time as improving other ecosystems services, such as soil fertility and the prevention of soil erosion.
