Different landscape features within a simplified agroecosystem support diverse pollinators and their service to crop plants

Abstract Context Landscape simplification is a main driver of insect decline, threatening crop pollination services. Changes in functional features simplified agroecosystems may impact the abundance wild pollinators. Objectives Here, we studied whether different pollinator groups based on life-history are differentially associated to landscape features, and how this affects service delivery. Methods Using window traps highly agroecosystem, surveyed abundances diversity with: (1) bare fence-lines separating pastures (control), (2) conifer hedgerows (3) farm gardens diverse exotic plant species (4) effluent-ponds, (5) newly established native-plantings, (6) gorse ( Ulex europaeus ) (7) open water channels across six twelve dairy farms. We also measured delivery potted pak choi Brassica rapa plots near 1–5 Results Pollinators at gardens, effluent-ponds delivered significantly more than fence-lines, with flies being effective pollinators bees all assessed. Taxa delivering differed features. The native bee Lasioglossum sordidum garden native-planting other drone Eristalis tenax contributed majority while calliphorid most hedgerows. Conclusions Conversion negatively on-farm its plants. However, farmers can benefit from enhancing containing that support non-bee proven deliver measurable
