蜜蜂可能会通过消耗公共资源来战胜野生蜜蜂，在鲜花丰富的栖息地已经失去的简化景观中可能更是如此。我们通过实验将蜂巢添加到9个站点来测试这一点，同时确保另外10个站点没有蜂巢。周围的景观，每个地理上分离的网站要么举行低（同质景观）或高（异质景观）的半天然草地的比例。添加蜜蜂抑制熊蜂密度在领域的边界和道路边缘均匀的景观，而没有这样的效果在异质景观检测。小觅食范围的熊蜂物种的比例丰度在蜜蜂网站比在控制网站在异质景观，而熊蜂群落在同质景观占主导地位的一个单一的物种与长觅食范围，无论是否加入蜜蜂。我们的结论是，蜜蜂可以影响熊蜂密度，但景观异质性修改了这种效果。
Honeybees might outcompete wild bees by depleting common resources, possibly more so in simplified landscapes where flower-rich habitats have been lost. We tested this by experimentally adding honeybee hives to nine sites while ensuring that ten additional sites were free from hives. The landscape surrounding each geographically separated site either held low (homogeneous landscape) or high (heterogeneous landscape) proportions of semi-natural grassland. Adding honeybees suppressed bumblebee densities in field borders and road verges in homogeneous landscapes whereas no such effect was detected in heterogeneous landscapes. The proportional abundance of bumblebee species with small foraging ranges was lower at honeybee sites than at control sites in heterogeneous landscapes, whereas bumblebee communities in homogeneous landscapes were dominated by a single species with long foraging range irrespective of if honeybees were added or not. We conclude that honeybees can impact bumblebee densities, but that landscape heterogeneity modified this effect.
