Biodiversity evaluation in agricultural landscapes : An approach at two different scales
Abstract Evaluating biodiversity in agricultural areas requires two steps: (i) adequate measurement and (ii) pertinent interpretation. Since the whole spectrum of biodiversity in the sense of the RioExpand

Population movements of arthropods between natural and cultivated areas
Abstract ‘Edge permeability’ between habitat patches in a mosaic landscape of mixed intense agriculture and semi-natural areas was investigated with directional trap devices along field borders andExpand

Biodiversity evaluation in agricultural landscapes: above-ground insects
Abstract In agriculture, sustainability can be linked to ecological resilience. In view of present or imminent environmental changes in agricultural landscapes, the diversity of species andExpand

Biodiversity indicators: the choice of values and measures
Abstract Ideally, an indicator for biodiversity is a linear correlate to the entity or aspect of biodiversity under evaluation. Different motivations for assessing entities or aspects of biodiversityExpand

The effects of windthrow on forest insect communities: a literature review
This paper reviews the effects that windstorm-induced drastic changes (micro-climate, soil, vegetation, and ground structural heterogeneity) have on forest insect communities. In the current contextExpand

The Swiss agri-environment scheme enhances pollinator diversity and plant reproductive success in nearby intensively managed farmland
Summary 1. Agri-environment schemes attempt to counteract the loss of biodiversity and associated ecosystem services such as pollination and natural pest control in agroecosystems. However, only aExpand

Interaction diversity within quantified insect food webs in restored and adjacent intensively managed meadows.
1. We studied the community and food-web structure of trap-nesting insects in restored meadows and at increasing distances within intensively managed grassland at 13 sites in Switzerland to test ifExpand

In search of the best correlates for local organismal biodiversity in cultivated areas
Based on a transect consisting of 19 identical trap stations in cultivated areas and seminatural habitats, the correlation of species numbers of higher taxonomic groups with total species numbers ofExpand

Regional biodiversity in an agricultural landscape: the contribution of seminatural habitat islands
Abstract An important goal of ecological compensation measures in agricultural areas is the conservation and enhancement of regional species diversity. However, some current European agri-environmentExpand

The European spruce bark beetle Ips typographus in a national park: from pest to keystone species
The influence of natural disturbance on biodiversity is poorly known in the intensively cultivated landscape of Europe. As an example of insect disturbance we studied effects of gaps generated byExpand
