“…The high values of weed diversity recorded in the dry farmland fields are similar to those found in other studies throughout Mediterranean Spain (e.g., José-María et al 2010, Ponce et al 2011, Concepción et al 2012. The higher biodiversity of the Mediterranean region compared with northern countries suggests that the biodiversity loss caused by agriculture intensification may also be higher (Ponce et al 2011). In our study, crop type seems to be the main factor explaining differences in weed richness, as it was much higher in either dry or irrigated wheat than in maize fields.…”

“…Only recently, the effects of agriculture intensification on plant diversity have been analyzed in Mediterranean Europe (José-María et al 2010, Ponce et al 2011, Concepción et al 2012, in contrast to the large number of studies performed in Atlantic and Continental Europe (e.g., Andreasen and Stryhn 2008;Firbank et al 2008;Cimalova and Lososová 2009;). Because climate and land-use policies are markedly different between these regions (see Caraveli 2000), there is a need for more information on the relative importance of different farmland management types for biodiversity conservation in Mediterranean agricultural landscapes.…”

The intensification of agriculture has increased production at the cost of environment and biodiversity worldwide. To increase crop yield in dry cereal systems, vast farmland areas of high conservation value are being converted into irrigation, especially in Mediterranean countries. We analyze the effect of irrigation-driven changes on the farm biota by comparing species diversity, community composition, and species traits of arable plants within crop fields from two contrasting farming systems (dry and irrigated) in Spain. We sampled plant species within 80 fields of dry wheat, irrigated wheat, and maize (only cultivated under irrigation). Wheat crops held higher landscape and per field species richness, and beta diversity than maize. Within the same type of crop, irrigated wheat hosted lower plant diversity than dry wheat at both field and landscape scales. Floristic composition differed between crop types, with higher frequencies of perennials, cosmopolitan, exotic, wind-pollinated and C4 species in maize. Our results suggest that irrigation projects, that transform large areas of dry cereal agro-ecosystems into irrigated crop systems dominated by maize, erode plant diversity. An adequate planning on the type and proportion of crops used in the irrigated agro-ecosystems is needed in order to balance agriculture production and biodiversity conservation.

“…Although these predators were present in all the treatment plots, their numbers in the nke treated and control plots were higher in comparison to other chemically insecticide treated plots. The finding of this study is in agreement with those of [24] who reported 20% increase in asilids abundance in organic fields compared to the conventional farming fields (which use chemical pesticides). Apart from repelling both adult and larvae, disrupting their development processes including sterility, nke is known to affect insect pests in various other ways such as causing confusion (immobilization) in the behaviour of adults [18].…”

“…Barbado and van Halder, 2009;Guerrero et al, 2014). Inconsistent results have been found in the literature concerning the beneficial effects of agroecosystems with lower levels of land-use management in relation to conventional agriculture (Ponce et al, 2011;Puech et al, 2014). In fact, several studies have shown that carabid beetles are influenced by agricultural practices, occurring generally in higher abundance or diversity in less intensive land-use systems, such as organic farming (e.g.…”

A B S T R A C TThe effects of land-use management and environmental features at different scales on carabid beetle diversity and trait structure were assessed across olive groves in northeastern Portugal. We selected organic and integrated olive groves that were distinct in terms of specific management practices, local linear features and landscape configurations. Besides the management intensification levels, differences in carabid diversity and community traits were mainly due to local habitat and ecological linear structures at a finer spatial scale. Carabid community traits related to disturbance, namely traits of body size and species dispersal ability, responded to land-use intensity and particular olive grove features were influencing diversity patterns. Within the olive grove patches, larger and brachypterous species were associated to plots with more dense vegetation cover while macropterous and small-sized species were more associated to open areas. Also, larger carabid species benefitted from higher patch size heterogeneity within the landscape mosaics. Our findings indicate that the effects of farming system is contingent on the specific management practices, local and linear features present in agroecosystems such as olive groves. Particularly, the influence of local features on carabid diversity patterns and community traits linked to dispersal and movement may be crucial in maintaining pest control at a landscape scale.
