预测野生蜜蜂在作物中的潜在授粉服务需要了解它们在田间的空间分布。田野边缘可以作为野生蜜蜂的筑巢和觅食栖息地，也可以是传粉昆虫的来源。传粉者群落组成的区域差异可能会影响蜜蜂的溢出。研究了区域和地方差异对农田野蜂物种丰富度、活动密度和个体大小空间分布的影响。我们采样蜜蜂都从外地中心，并在两种不同类型的半自然领域的边缘，草带和树篱，在12草莓领域。这些油田分布在北方的四个地区，代表了近1100公里长的南北梯度。即使在这个梯度上，采样期间的白天温度在不同地区之间也没有显着差异，因此可能不会影响蜜蜂的活动。蜜蜂物种丰富度较高的领域边缘相比，独立的领域大小的领域中心。但在个体大小和活动密度上，中心与边缘无差异。与此相反，蜜蜂的活动密度增加向南部地区，而平均身体大小增加向北。总之，我们的研究揭示了欧洲地区蜜蜂多样性的一般模式，但不是活动密度，向外地内部下降，这表明传粉者的功能多样性的好处可能难以实现通过溢出效应从利润率到作物。我们还确定了不同的区域模式，蜜蜂的多样性和活动密度，这应该考虑到保护管理。
Predicting potential pollination services of wild bees in crops requires knowledge of their spatial distribution within fields. Field margins can serve as nesting and foraging habitats for wild bees and can be a source of pollinators. Regional differences in pollinator community composition may affect this spill-over of bees. We studied how regional and local differences affect the spatial distribution of wild bee species richness, activity-density and body size in crop fields. We sampled bees both from the field centre and at two different types of semi-natural field margins, grass strips and hedges, in 12 strawberry fields. The fields were distributed over four regions in Northern Europe, representing an almost 1100 km long north-south gradient. Even over this gradient, daytime temperatures during sampling did not differ significantly between regions and did therefore probably not impact bee activity. Bee species richness was higher in field margins compared with field centres independent of field size. However, there was no difference between centre and margin in body-size or activity-density. In contrast, bee activity-density increased towards the southern regions, whereas the mean body size increased towards the north. In conclusion, our study revealed a general pattern across European regions of bee diversity, but not activity-density, declining towards the field interior which suggests that the benefits of functional diversity of pollinators may be difficult to achieve through spill-over effects from margins to crop. We also identified dissimilar regional patterns in bee diversity and activity-density, which should be taken into account in conservation management.
