项目摘要

Bee pollination plays a major role in maintaining the plant diversity of tropical ecosystems. Worldwide, agriculture also relies upon bee pollination, which plays a central role in many economically important crops. Increased destruction of bee-friendly habitat and declines in honey bee populations have led to interest in other bee pollinators, such as stingless bees, which have a key role in preserving native plant diversity and agriculture. However, little is known about how stingless bees influence plant gene flow by where they choose to forage. In particular, the role of competition, aggression, and interceptive eavesdropping (the ability of some stingless bee species to intercept foraging information intended for nestmates) on flower visitation and pollination are not well understood. The researchers will combine field studies of stingless bee foraging and mathematical modeling to determine how these foraging patterns vary with foraging strategy and how competition among stingless bees can change foraging patterns. Their results will increase our understanding of how interceptive eavesdropping shapes bee foraging and contribute to mathematical models useful for preserving native plant diversity and the management of these alternative agricultural pollinators. The research will also allow minority and underprivileged students to gain direct field research experience and provide outreach teaching the importance of native pollinators and the scientific method through the web and science workshops.

蜜蜂授粉在维持热带生态系统的植物多样性中起着重要作用。在全球范围内，农业也依靠蜜蜂授粉，这在许多经济上重要的作物中起着核心作用。蜜蜂种群中对蜜蜂友好型栖息地的破坏增加并减少了对其他蜜蜂传粉媒介的兴趣，例如无刺蜜蜂，这些蜜蜂在保护本地植物多样性和农业方面具有关键作用。但是，关于无刺蜜蜂如何通过选择觅食的地方影响植物基因流动的知之甚少。特别是，尚不清楚竞争，侵略性和拦截窃听的作用（某些无刺蜜蜂物种拦截饲养信息的能力）在花卉探视和授粉方面的作用尚不清楚。研究人员将结合无刺蜜蜂觅食和数学建模的现场研究，以确定这些觅食模式如何随觅食策略而变化以及无刺蜜蜂之间的竞争如何改变觅食模式。他们的结果将增加我们对拦截性窃听形状觅食的理解，并为数学模型有助于保存天然植物多样性以及这些替代农业传粉媒介的管理有用。这项研究还将允许少数民族和贫困学生获得直接的现场研究经验，并通过网络和科学讲习班提供外展教学本地传粉媒介的重要性和科学方法。
