This project addresses impacts of the invasive shrub, Amur honeysuckle (AH), on pollination in native species, seed predation by rodents, and seed dispersal by birds and rodents. This project will test: 1) if AH distracts pollinators (bees, butterflies, and moths) from visiting native plants; 2) if AH fruits and cover of leaves influence the abundance of white-footed mice, important seed predators; and 3) if AH distracts seed dispersers from attending native species. A combination of natural experiments (i.e., where abundance of AH differs naturally) and manipulative experiments (i.e., where AH is removed from large tracts) will be used to determine how this invasive shrub influences processes that maintain native plant and animal populations. Invasive species are very significant threat to biological diversity, costing over $137 billion/year for control in the U.S. Investigating the effects of invasives provides vital information for their eradication and reduction of their economic impacts. If the stated predictions are confirmed, invasive species should be considered more of a threat than previously thought, because they have less obvious indirect effects on native diversity through their impacts on pollination and seed dispersal processes. Because of the large scale of the project, many high school and undergraduate students will be trained in basic ecological and conservation theory and field methods.

该项目涉及侵入性灌木，阿米尔金银花（AH），对本地物种的授粉，啮齿动物捕食的授粉以及鸟类和啮齿动物的种子散布的影响。该项目将测试：1）如果AH分散了授粉媒介（蜜蜂，蝴蝶和飞蛾）的注意力，请参观本地植物； 2）如果Ah果实和叶子的覆盖会影响白脚的丰富小鼠，那么重要的种子捕食者； 3）如果AH分散了种子分散者的注意力，请参加本地物种。将使用自然实验（即AH自然不同）和操纵实验（即，从大区域中去除AH）的组合来确定这种侵入性灌木如何影响天然动植物种群的过程。 入侵物种对生物多样性是非常重大的威胁，在美国，耗资超过1,370亿美元的/年来控制入侵者的影响，为消除和减少其经济影响提供了重要的信息。如果确认了既定的预测，则应将入侵物种视为比以前想象的更多的威胁，因为它们通过对授粉和种子分散过程的影响对天然多样性的间接影响不太明显。由于该项目的规模很大，许多高中和本科生将接受基本生态和保护理论和现场方法的培训。
