Some wild bees can persist in human‐altered habitats in the face of global wild bee decline. To date, however, little is known about why those bees can tolerate human disturbances. Here we hypothesized that wild bees living in human‐altered habitats could achieve their nesting resources and floral resources. Moreover, persistent provision of those resources could enhance their populations. The foraging areas of solitary, cavity‐nesting bees Anthophora waltoni were determined in two agricultural ecosystems with rich bee populations. The influences of seminatural habitats, nesting resources and farmlands on A. waltoni visit density were assessed by modelling bee density against landscape factors in 17 agricultural ecosystems. Moreover, temporal availabilities of those resources were measured across the last three decades. A. waltoni used vetch fields and field margins, instead of seminatural habitats, as foraging areas. The area of brick walls and the area of farmlands, as well as their temporal increases, synergistically positively influenced A. waltoni visit density on vetch flowers. The percentage of buildings and farmlands increased across the last three decades in spite of a slowdown in 5‐year growth of brick walls. The results demonstrated the synergistically positive effects of nesting resources and floral resources, as well as persistent provisions of those resources, on A. waltoni populations in agricultural ecosystems. A. waltoni could live in the human‐altered habitats because they persistently achieved their nesting resources and floral resources.

砖墙和农田对 Anthophora waltoni 种群的协同积极影响

面对全球野生蜜蜂的减少,一些野生蜜蜂可以在人类改变的栖息地中生存。然而,迄今为止,人们对为什么这些蜜蜂能够忍受人类干扰的原因知之甚少。在这里,我们假设生活在人类改变的栖息地的野生蜜蜂可以获得它们的筑巢资源和花卉资源。此外,持续提供这些资源可以增加他们的人口。在蜜蜂种群丰富的两个农业生态系统中,确定了独居、空巢蜂 Anthophora waltoni 的觅食区域。通过针对 17 个农业生态系统中的景观因素对蜜蜂密度进行建模,评估了半自然栖息地、筑巢资源和农田对 A. waltoni 访问密度的影响。此外,这些资源的时间可用性是在过去三年中衡量的。一种。waltoni 使用野豌豆田和田地边缘,而不是半自然栖息地,作为觅食区。砖墙面积和农田面积,以及它们的时间增加,协同积极地影响 A. waltoni 对野豌豆花的访问密度。尽管砖墙的 5 年增长放缓,但在过去的 30 年中,建筑物和农田的百分比有所增加。结果表明筑巢资源和花卉资源以及这些资源的持续供应对农业生态系统中的 A. waltoni 种群具有协同的积极影响。A. waltoni 之所以能够生活在人类改变的栖息地,是因为它们坚持获取筑巢资源和花卉资源。砖墙面积和农田面积,以及它们的时间增加,协同积极地影响 A. waltoni 对野豌豆花的访问密度。尽管砖墙的 5 年增长放缓,但在过去的 30 年中,建筑物和农田的百分比有所增加。结果表明筑巢资源和花卉资源以及这些资源的持续供应对农业生态系统中的 A. waltoni 种群具有协同的积极影响。A. waltoni 之所以能够生活在人类改变的栖息地,是因为它们坚持获取筑巢资源和花卉资源。砖墙面积和农田面积,以及它们的时间增加,协同积极地影响 A. waltoni 对野豌豆花的访问密度。尽管砖墙的 5 年增长放缓,但在过去的 30 年中,建筑物和农田的百分比有所增加。结果表明筑巢资源和花卉资源以及这些资源的持续供应对农业生态系统中的 A. waltoni 种群具有协同的积极影响。A. waltoni 之所以能够生活在人类改变的栖息地,是因为它们坚持获取筑巢资源和花卉资源。尽管砖墙的 5 年增长放缓,但在过去的 30 年中,建筑物和农田的百分比有所增加。结果表明筑巢资源和花卉资源以及这些资源的持续供应对农业生态系统中的 A. waltoni 种群具有协同的积极影响。A. waltoni 之所以能够生活在人类改变的栖息地,是因为它们坚持获取筑巢资源和花卉资源。尽管砖墙的 5 年增长放缓,但在过去的 30 年中,建筑物和农田的百分比有所增加。结果表明筑巢资源和花卉资源以及这些资源的持续供应对农业生态系统中的 A. waltoni 种群具有协同的积极影响。A. waltoni 之所以能够生活在人类改变的栖息地,是因为它们坚持获取筑巢资源和花卉资源。
