Journal of Animal Ecology, EarlyView.In this paper, we show that pronounced differences in pollinator communities exist between grasslands embedded in contrasting agricultural landscape contexts. Opportunistic foraging strategies of most pollinators resulted in large interaction turnover, but these shifts did not translate into major changes in overall network structure, most likely as a ...

Ants contribute to raspberry pollination in protected cropping systems
Agricultural and Forest Entomology, EarlyView.Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Evidence of forage distance limitations for small bees (Hymenoptera: Apidae)
European Journal of Entomology, 2015 The distribution of ground-nesting bees was investigated using transects of water traps in a mosaic of nesting and forage habitats at Shotover Hill in Oxfordshire, UK. The site includes a large area of ground-nesting bee activity and is adjoined on three
