TL;DR: In this paper, a large-scale study of 25 agricultural landscapes in seven European countries, the authors investigated relationships between species richness in several taxa, and the links between biodiversity and landscape structure and management.

TL;DR: The total landscape species richness of all groups was most strongly affected by increased proximity of semi-natural habitat patches and the effect of increased habitat diversity appeared to be of secondary importance to total species richness but caused a shift in the relative contribution of α and β diversity towards the latter.

TL;DR: In this paper, the authors analyzed five arthropod taxa covering a broad range of functional aspects (wild bees, true bugs, carabid beetles, hoverflies and spiders) in 24 landscapes (4 x 4 km) across seven European countries along gradients of both land-use intensity and landscape structure.

TL;DR: In this article, the intensity of agricultural production was assessed in 25 landscape test sites across temperate Europe using a standardised farmer questionnaire and the intensity indicators, nitrogen input (to arable crops and to permanent grassland), density of livestock units and number of pesticide applications (herbicides, insecticides, fungicides and retardants), were recorded and integrated into an overall intensity index.

TL;DR: Habitat patch availability and habitat quality are the main drivers of functional group composition and plant species richness in European agricultural landscapes and in order to conserve vascular plant species diversity in agricultural landscapes.
