Effects of landscape simplification
The model testing for a linear relationship between service provision
and landscape simplification and its interaction with local flower
presence fitted the data better than a model testing for hump-shaped
relationships (Table S3). Pollination, but not pest control services,
decreased linearly with landscape simplification (12% decrease from 50
to 100% crops in the surrounding landscape), irrespective of the
presence of a floral planting (no significant floral planting ×
landscape simplification interaction; Fig 4; Table 1).
