9902269DoakThe ecology of invasive exotic species is a very important topic and concern among both applied and theoretical ecologists. However, very few studies have examine this problem using a solid experimental design. This study will examine the impacts of the invasive European honeybee (Apies mellifera) on native pollinator and plant communities in coastal California. This work will investigate and quantitatively link the impacts of European bee on foraging behavior and colony reproductive success for an important group of native pollinators, the bumblebees (Bombus spp). This is proposed to be done by combinations of large-scale manipulations of bee densities, measurement of resource availability and depletion, monitoring of bumblebee colony performance and quantitative modeling of competitive effects. In addition to providing information on the impact of invasive species on native communities, this work will provide insight into how and why invasive species cause community-level effects and it will contribute to a greater understanding of competitive interactions among behaviorally flexible colonial organisms.

外来入侵物种的生态学是应用生态学家和理论生态学家关注的一个重要问题。然而，很少有研究使用可靠的实验设计来检验这个问题。本研究将研究入侵的欧洲蜜蜂对加利福尼亚沿海地区本地传粉者和植物群落的影响。这项工作将调查和定量联系欧洲蜜蜂对觅食行为和一个重要的本地传粉者群体的群体繁殖成功的影响，大黄蜂（Bombus spp）。这建议通过大规模操纵蜜蜂密度、测量资源可用性和枯竭、监测大黄蜂群体表现和竞争效应的定量建模来完成。除了提供有关入侵物种对本地群落影响的信息外，这项工作还将深入了解入侵物种如何以及为什么会引起社区层面的影响，并有助于更好地理解行为灵活的群体生物之间的竞争相互作用。
