    Response of bee and hoverfly populations to a land-use gradient in a Quebec floodplain
    (Kluwer, 2022-11-03) Slupik, Olivier; McCune, Frédéric; Watson, Chris; Proulx, Raphaël; Fournier, Valérie
    The main objective of this study was to inventory the abundance and species richness of wild bees and hoverflies in the Lac Saint-Pierre floodplain according to a land-use gradient. In 2019 and 2020, pollinators were sampled using pan-traps in three landscape types: Crop field margins, Perennial hayfields, and Natural habitats. Bee and hoverfly populations were dominated by a few species throughout the study area. Crop field margins contained greater floral availability and attracted more individuals and species of bees than other landscape types. Although hoverflies were not affected by either land-use type or flooding, the abundance and species richness of bees appeared to be reduced when spring flooding lasted longer, suggesting a mortality effect of flooding on their populations.
