Carabid functional diversity is enhanced by conventional flowering fields, organic winter cereals and edge habitats

The continued decline in farmland biodiversity in Europe despite substantial funding for agri-environment schemes (AES) has prompted calls for more effective biodiversity conservation measures. The current AES regime allows for both holistic measures, such as organic farming, that broadly target the agricultural environment and biodiversity-specific measures, such as flowering fields, but little is known of their relative efficacies. To address...
