- Bumble bees fill an important function in temperate, boreal and alpine ecosystems as pollinators of wild plants and cultivated crops. Global declines in population size of many bumble bee species call for knowledge about how habitats influenced by human land use can be managed to accommodate diverse bumble bee communities.
- We carried out a field experiment to study effects on bumble bee communities in power‐line clearings in response to different vegetation clearing practices: (i) cutting, (ii) cutting and removing, and (iii) not cutting the woody vegetation, whilst simultaneously assessing the effect of environmental variables, both individually and in interaction with treatment.
- Cutting the woody vegetation improved habitat quality for bumble bees relative to the uncut treatment, whereas removal of woody debris provided no additional benefit. The treatment effect on bee richness, diversity, abundance, and the abundance of generalist bees depended on local forb species richness. Increasing functional variation of forbs and cover of forbs with nectar tubes were positively related to species richness and abundance of bees, irrespective of treatment.
- The abundance of specialized long‐tongued and late emerging bumble bees – which are of special conservation interest – were higher in the cut and cut‐remove treatments and increased with functional variation of forb species irrespective of treatments.
- Management to improve habitat conditions for bumble bees in power‐line clearings does not require costly removal of woody debris after cutting, but more frequent cutting can benefit specialized bumble bee species of particular conservation interest.

在电力线清理中大黄蜂社区：实验性管理实践的影响
- 大黄蜂在温带，北方和高山生态系统中担当着野生植物和栽培作物的传粉媒介的重要角色。全球许多大黄蜂物种种群数量的下降要求人们了解如何管理受人类土地利用影响的栖息地，以适应各种大黄蜂群落。
- 我们进行了一项野外实验，以研究针对不同植被清理措施而对电力线清理中大黄蜂群落的影响：（i）砍伐，（ii）砍伐和清除，以及（iii）不砍伐木本植被，同时进行评估环境变量的影响，无论是单独还是与治疗相互作用。
- 相对于未砍伐处理，砍伐木本植被可以改善大黄蜂的栖息地质量，而去除木本碎屑则没有任何其他好处。对蜜蜂的丰富性，多样性，丰富度和多面手蜜蜂的丰富度的处理效果取决于当地的福布斯物种丰富度。不论处理如何，增加的花蜜的功能变化和用花蜜管覆盖的花蜜与蜜蜂的物种丰富度和丰度呈正相关。
- 在割割和割除处理中，具有特殊保护意义的专门长舌和晚期新兴大黄蜂的数量较高，而不论何种处理，其随杂草种类的功能变化而增加。
- 在电力线清理中，为改善大黄蜂的栖息地条件而进行的管理不需要在切割后昂贵地清除木屑，但是更频繁的切割可以使对特别具有保护意义的大黄蜂物种有利。
