TL;DR: The STEP project is documenting critical elements in the nature and extent of declines in pollinator declines, examining key functional traits associated with pollination deficits, and developing a Red List for some European pollinator groups.

TL;DR: In this paper, the authors investigate how area and habitat diversity, mediated by shrub encroachment after grassland abandonment, affect species richness of orthopterans in island-like grasslands, and how contrasting mobility might alter species richness response to both factors.

TL;DR: It was found that apple-dominated landscapes drastically reduced wild bee species richness and abundance in the orchard compared to landscapes dominated by either grassland or forest, while no interactive effect was found between temperature and landscape context.

TL;DR: The differential response of the three cultivars suggested opportunities to use cultivars that are less dependent on insect pollination in landscapes where this service has been deteriorated, and increased access of nitrogen seems to partly compensate yield losses from poor Insect pollination.

TL;DR: Complex landscapes characterized by highly connected crop–noncrop mosaics may be best for long-term conservation biological control and sustainable crop production, but experimental evidence for detailed recommendations to design the composition and configuration of agricultural landscapes that maintain a diversity of generalist and specialist natural enemies is still needed.
