Abstract

and pollination services. However, context and species-specificresponses makeit challenging to draw general conclusions about the most important componentsof landscapes that support diverse and abundant pollinator communities.2. In this study, we took a functional-traitsapproach to community assembly andtested the hypothesis that landscape properties act most strongly on pollinatorsindirectly, through their influence on flowering plant communities. Using plantand pollinator data from 96 landscapes in Britain, we tested the associations betweenplant and pollinator communities and local environmental factors, such ashabitat cover and configuration, using path analysis based on Mantel and partialMantel statistics.3. When all pollinators were considered, we found that the environmental factorshad stronger links to the composition of flowering plant communities than to thecomposition of pollinator communities. Further, the flowering plant communitywas strongly linked to the pollinator community suggesting a mediating role betweenland use and pollinators. When separating the pollinator community intotaxonomic groups, we found the same result for hoverflies, but wild bees werelinked to both environmental factors and flowering plants.
