“…Our results agree with some other studies showing that the introduction of flowering plants into agricultural settings leads to increased arthropod abundance (Rebek et al, 2005;Walton & Isaacs, 2011). Higher arthropod diversity was associated with greater compositional diversity of weed cover (Benton et al, 2003;Gaigher & Samways, 2010). Our results showed that the number of total insects was lower in meadows and pastures than in wildflower strips of field paths and weedy areas, what is similar to the results of Zurbrügg & Frank (2006).…”

“…In almost all localities, vegetation structure was the best explanatory factor for insect distribution, abundance, and species richness. Our results are similar to the results reported in other studies of arthropods in organic and intergrated vineyards (Gaigher & Samways, 2010). The best plant families for preserving predators (Coccinellidae, Syrphidae and Chrysopidae) are Apiaceae, Asteraceae and Chenopodiaceae (Fiedler et al, 2008;Bertolaccini et al, 2011).…”

“…As Raymond et al (2000), we also found ladybugs (all developmental stages) on Chenopodium spp. Gaigher & Samways (2010) indicated that abundance of carabids was higher in organic than in the integrated vineyard. O' Rourke et al (2008) and Eyre et al (2012) reported that crop rotation and diverse crop habitats increased Carabidae activity, density and diversity.…”

Weeds and non-cultivated plants have a great impact on abundance and diversity of beneficial arthropods in agriculture. The main aim of this work was to study the influence of the ecological infrastructure (meadows and weedy margins) on the arthropod composition in vineyard surrounding landscape. Research was carried out from May to October during three years. Sampling took place in the ecological infrastructure of three differently managed vineyards (organic, integrated and extensive). Three zones were chosen in each vineyard (3 m, 10 m, and 30 m from the edge of the vineyard). Samples were taken using a standardised sweep net method. In total, we captured 6032 spiders and 1309 insects belonging to 4 orders and 10 families. Arthropod fauna was numerically dominated by Aranea (82.1%); among insects, Coleoptera was the most abundant taxonomic group (10.6%); Neuroptera showed the lowest value (0.88%). Significant differences were found between sites and zones. Organic vineyard showed the highest abundance of arthropods (92.41% were spiders) and in the integrated vineyard there was a 23% of insects. Both the highest abundance of arthropods and the highest Shannon Index value (2.46) was found 3 m away from the edge of the vineyard. Results showed that spiders were the dominant arthropods and ladybugs the dominant insects. Weedy strips near the edge of the vineyard contained a high number of insects and spiders. Our results support the importance of weedy margins in enhancing the population of arthropods as well as in biodiversity promotion. Well-managed field margins could play important role in biological control of vineyard pests.

“…For example, though vineyards have very different arthropod communities than those in natural vegetation, organic vineyards support greater diversity than do more intensively managed vineyards (Gaigher and Samways 2010). However, these effects may be taxon dependent; for 22 instance, organic vineyard management benefits richness of monkey beetles (crucial pollinators), but not bees (Kehinde and Samways 2012).…”

Supporting conservation with biodiversity research in sub-Saharan Africa’s human-modified landscapes

Protected areas cover 12% of terrestrial sub-Saharan Africa. However, given the inherent inadequacies of these protected areas to cater for all species in conjunction with the effects of climate change and human pressures on protected areas, the future of biodiversity depends heavily on the 88% of land that is unprotected. The study of biodiversity patterns and the processes that maintain them in human-modified landscapes can provide a valuable evidence base to support science-based policy-making that seeks to make land outside of protected areas as amenable as possible for biodiversity persistence. We discuss the literature on biodiversity in 2 sub-Saharan Africa"s human-modified landscapes as it relates to four broad ecosystem categorizations (i.e. rangelands, tropical forest, the Cape Floristic Region, and the urban and rural built environment) within which we expect similar patterns of biodiversity persistence in relation to specific human land uses and land management actions. Available research demonstrates the potential contribution of biodiversity conservation in human-modified landscapes within all four ecosystem types and goes some way towards providing general conclusions that could support policy-making. Nonetheless, conservation success in humanmodified landscapes is hampered by constraints requiring further scientific investment, e.g. deficiencies in the available research, uncertainties regarding implementation strategies, and difficulties of coexisting with biodiversity. However, information currently available can and should support efforts at individual, community, provincial, national, and international levels to support biodiversity conservation in human-modified landscapes.

“…In vineyards, ants are one of the most abundant arthropod group (Addison et al, 2013;Thomson et al, 2004), while spiders are one of the most abundant predator group (Gaigher & Samways, 2010;Pérez-Bote & Romero, 2012).…”

This study, held in vineyards from Douro Demarcated Region, aimed to: a) identify the communities and main functional groups of spiders and ants; b) check patterns of co-occurrence between the two communities; and c) evaluate the impact of ground cover and adjacent non-crop habitats in the proximity of vineyards, on the two communities. Samplings were done using pitfall trapping. Twenty species of ants and 44 species of spiders were identified, which included respectively three and nine Iberian endemic species. Aphaenogaster gibbosa (Latreille 1798), Aphaenogaster iberica Emery 1908, Cataglyphis hispanica (Emery 1906), Cataglyphis iberica (Emery 1906), Messor barbarus (L. 1767) and Tapinoma nigerrimum (Nylander 1856) totalized 71.21% of ants. Alopecosa albofasciata (Brullé 1832), Callilepis concolor Simon 1914, Eratigena feminea Simon 1870, Zodarion alacre (Simon 1870) and Zodarion styliferum (Simon 1870) accounted for 38% of spiders. Abundance of both ant-mimicking and ant-eating spiders were positively correlated with Formicinae, while only ant-eating spiders showed positive correlation with Myrmicinae ants. All genera/ species of ant-associated spider were associated with one or more genera/ specie of ants. The abundance of specialist spiders was higher in areas where abundance of ants was also higher. Sheet web weavers spiders were found to be positively correlated with the percentage of ground cover. The present study a) stresses that vineyard agroecosystem support a rich assemblage of ants and spiders evincing that wine production and species conservation is possible and b) the co-occurrence between some species of this two groups is not determined by random patterns.
