人类对热带雨林的干扰可能会间接地改变传粉者群落，这是资源可利用性变化的结果。我们研究了机制，人为干扰影响社会的主要传粉者，无刺蜂，在马来西亚沙捞越。我们调查了森林结构和开花活动，并进行了巢普查和诱饵陷阱调查的无刺蜜蜂，无论是在原始森林和森林砍伐和轮垦干扰。演替后期乔木和胸径>50 cm的大树密度，原始林高于干扰林。开花树的密度较低的一年后，伐木，但恢复在老干扰的森林，因为活跃的开花的先锋树，成为建立后的干扰。无刺蜂只在大树上筑巢，且巢密度与大树密度呈正相关。然而，我们发现觅食的数量和植物区系参数之间没有关系。有些物种喜欢在龙脑香树上筑巢，而另一些则喜欢死树。诱饵调查结果还表明，一些物种丰富的原始森林，而其他物种丰富的干扰森林。这些结果表明，人类干扰改变了无刺蜂群落的物种组成。蜜蜂群落的这种变化可能会影响植物的繁殖成功，并最终影响森林的组成。
Human disturbance of tropical rainforests may change pollinator communities indirectly as a result of changes in resource availability. We studied the mechanisms by which human disturbance affects a community of major pollinators, stingless bees, in Sarawak, Malaysia. We surveyed forest structure and flowering activity, and conducted a nest census and a bait-trap survey of stingless bees, both in primary forests and in forests disturbed by logging and shifting cultivation. The densities of late successional trees and large trees (diameter at breast height >50 cm) were higher in the primary forests than in the disturbed forests. The density of flowering trees was lower one year after logging, but recovered in old disturbed forests because of the active flowering of pioneer trees that became established after the disturbance. Stingless bees nest only in large trees, and nest density was positively correlated with the density of large trees. However, we found no relationship between the numbers of foragers and floristic parameters. Some species preferred nesting in dipterocarps, while others preferred dead trees. The results of the bait-trap survey also indicated that some species were abundant in the primary forests, whereas other species were abundant in the disturbed forests. These results suggest that human disturbance alters the species composition of the stingless bee community. Such changes in the bee community may affect the reproductive success of plants, and ultimately forest composition.
