Ground beetles (Coleoptera: Carabidae) on a recently established wood-pasture: a case study from southwest Germany-Historical experience shows that wood-pastures provide high habitat diversity and thus also a high degree of species diversity, and as such they have been under discussion for some years as a conservation measure. However, the developm...
Article
Full-text available
Agricultural intensification is a major cause of biodiversity loss. Organic farming may counteract the loss of species, however, knowledge about its benefits for perennial agroecosystems such as vineyards is incomplete. We therefore analyzed the effects of organic viticulture on carabid beetles, a frequently used indicator group in agroecology. We...
Article
Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop y...

Annual crops are generally assumed to host simplified arthropod communities that depend on immigration from the surrounding landscape. Perennial, low-input crops such as olive groves are likely to depend less on immigration from other habitats, however, studies on the landscape ecology of perennial crops are scarce. This paper studies the assemblag...
Article
The expansion and intensification of agriculture are the main causes of current insect declines. Pollinators like cavity-nesting bees can be limited by reduced nesting and feeding opportunities in farmland. As insects constitute the bulk of terrestrial biodiversity and fulfill important ecological functions, there is an urgent need to identify ways...
Article
Full-text available
Background Examining the effects of pesticides is difficult in regions such as Western Europe because of the relatively ubiquitous use of agrochemicals and the lack of unaffected areas. To study a wide gradient of agrochemical stress, we conducted a study in Central Romania, where traditional agriculture, which is assumed to use less agrochemicals,...
Article
Full-text available
Agricultural management should aim at high densities of beneficial organisms such as spiders. Here, we asked whether spiders in vineyards can be promoted either by using novel disease resistant grape varieties that allow for a reduced number of fungicide applications, or by minimal pruning which enhances the structural complexity of the grapevine c...
Article
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...
