Data and analyses for: Woodlands facilitate reproductive behaviour and niche partitioning in farmland bumblebee communities

Open and closed woodland likely dominated Europe’s landscapes during the evolution of its contemporary pollinator diversity, contributing distinct floral and non-floral resources, and cooler and darker microclimates, to otherwise treeless environments. As such, we would expect present-day, generalist pollinator species, such as farmland bumblebees, to exploit woodland resources to differing degrees, and for evolutionary adaptations, such as species’ light sensitivity, to accord with relative use of shaded understories. We would also expect exploitation to differ between the pollen-collecting and reproductive castes. However, a lack of temperate woodland sampling has meant these predictions remain largely untested. To address this knowledge gap, we sampled bumblebee activity (activity-density) with blue vane traps in shaded woodland understories and in sun-exposed field margins and woodland canopies from May to July, at 12 sites across agricultural landscapes in Norfolk, England.
