Abstract The loss of floral resources is a leading cause wild bee decline in agricultural landscapes, but little known about the temporal aspects resource limitation for both social and solitary bees. Understanding when are most needed crucial optimal design pollinator conservation measures. We surveyed bees flowers 160 semi‐natural habitat patches multiple times per year (May–July) 5 years. identified seasonality examined inter‐ intra‐annual patterns at local landscape scales. Floral...
Agricultural intensification has resulted in a decline insect biodiversity and threatens the provision of valuable ecosystem services. Agri-environment schemes (AESs) have been implemented an effort to conserve on farmland increase agricultural sustainability, but their effectiveness can vary widely. To better determine which factors influence AES effectiveness, relative roles local habitat features, quality, landscape context need be further explored. The aim this study was most important...
Abstract To increase pollinator populations, international policy targets minimum levels of seminatural habitat cover, but it is unknown whether improving the quality existing habitats could bring similar benefits without need reducing cropland area. Using data we collected in 26 Italian agricultural landscapes during entire flying season, explored relative importance quantity (seminatural cover) and (flower availability) on densities habitats. We obtained transect‐based counts estimated...
Abstract Mass‐flowering crops have the potential to benefit pollinator conservation while still contributing agricultural production, but their effects on pollinators can be variable and remain uncertain. Lupin could particularly suitable for because it is a late‐flowering legume crop, its never been investigated. We tested intra‐ interannual of lupin cultivation wild bees in landscapes with no history cultivation. To do this, we surveyed semi‐natural habitats before, during, after bloom...
Abstract Novel relationships between the floral morphology of introduced plants and trophic native pollinators have been hypothesized to cause strong natural selection on both parties, but evidence for such is rare. We capitalized a disturbance examine an plant, Heliconia wagneriana , island Dominica, before after Hurricane Maria. Prior hurricane, female Anthracothorax jugularis hummingbirds, which longer bills than males, were main visitor H. directional corolla length was insignificant....
