Differential effects of semi-natural habitats and organic management on spiders in viticultural landscapes

Organic management has the potential to mitigate negative impacts of intensive farming on biodiversity. We aimed to determine the effects of management system (organic vs. conventional), local habitat conditions and the surrounding landscape on ground-dwelling spiders (Arachnida: Araneae) in vineyards. We studied spider species richness, abundance and community composition in fifteen pairs of conventional and organic vineyards along a gradient...
