Most plant species depend on animals for successful reproduction. However, many plants and their associated pollinators are declining for reasons that are not well known. This project examines the extent to which pollen limitation is due to reduced movements of pollinators caused by landscape fragmentation and habitat loss. Since most pollinators are very small, the effects of habitat fragmentation on their movement has never before been tested. A large-scale experiment designed to disentangle the effects of tropical forest landscape connectivity, patch size, and habitat loss on plant pollination will test this idea. The study will be conducted in a tropical forest; this forest type is declining rapidly and plant-pollinator interactions in tropical forests is often highly specialized.The project will capitalize on the charisma and diversity of tropical hummingbirds to transmit ideas about the importance of biodiversity conservation and ecosystem services to the general public. Results will be transferred to over 10,000 school children and undergraduates annually. School children in Oregon and Costa Rica will take part in a citizen-based monitoring effort to test whether landscape fragmentation affects hummingbirds.

大多数植物物种依靠动物成功繁殖。然而，许多植物及其相关的传粉者正在减少，原因尚不清楚。该项目研究花粉限制的程度是由于景观破碎化和栖息地丧失造成的传粉者的运动减少。 由于大多数传粉者都很小，栖息地破碎化对它们的运动的影响以前从未被测试过。 一项旨在解开热带森林景观连通性、斑块大小和栖息地丧失对植物授粉影响的大规模实验将检验这一想法。该研究将在热带森林中进行;这种森林类型正在迅速减少，热带森林中的植物-传粉者相互作用往往是高度专业化的，该项目将利用热带蜂鸟的魅力和多样性向公众传播关于生物多样性保护和生态系统服务重要性的想法。每年将向10，000多名在校儿童和大学生提供研究结果。俄勒冈州和哥斯达黎加的学童将参加一项以公民为基础的监测工作，以测试景观破碎化是否会影响蜂鸟。
