考虑到世界各地城市的预期扩张，了解城市化对蜜蜂动物群的影响是保护蜜蜂的一个主要问题。这项研究的目的是了解城市化如何影响沿不透水表面梯度的野生蜜蜂群落，并确定景观组成和植物资源可获得性对这些群落的影响。我们选择了12个地点，其不透水表面(停车场、道路和建筑物覆盖的土壤)的比例在500米半径内从0.06%到64.31%不等。我们采用平底锅诱捕法收集数据，并估计了半径500米范围内站点的景观组成和半径200米范围内植物组合的物种丰富度。我们收集了74个物种的1104只蜜蜂。景观尺度上不透水表面的比例对野生蜜蜂丰富度和物种丰富度有负面影响，而当地花卉组成对野生蜜蜂丰富度和物种丰富度没有影响。地面筑巢的蜜蜂对城市化梯度特别敏感。这项研究为城市化对蜜蜂聚集的影响提供了新的证据，景观尺度上不透水表面的比例成为驱动这些聚集的关键因素。
Given the predicted expansion of cities throughout the world, understanding the effect of urbanization on bee fauna is a major issue for the conservation of bees. The aim of this study was to understand how urbanization affects wild bee assemblages along a gradient of impervious surfaces and to determine the influence of landscape composition and floral resource availability on these assemblages. We chose 12 sites with a proportion of impervious surfaces (soil covered by parking, roads, and buildings) ranging from 0.06% to 64.31% within a 500 m radius. We collected using pan trapping and estimated the landscape composition of the sites within a 500 m radius and the species richness of plant assemblages within a 200 m radius. We collected 1104 bees from 74 species. The proportion of impervious surfaces at the landscape scale had a negative effect on wild bee abundance and species richness, whereas local flower composition had no effect. Ground‐nesting bees were particularly sensitive to the urbanization gradient. This study provides new evidences of the impact of urbanization on bee assemblages and the proportion of impervious surfaces at the landscape scale emerged as a key factor that drives those assemblages.
