Pollinators provide enhanced fruit and seed production for roughly 35% of global crop production and 75% of crop types. Wild pollinator populations are currently suffering from habitat loss, while semi-domesticated pollinators, particularly the most widely used crop pollinator, the European honey bee, are declining in North America and Europe due to diseases, pesticides and unknown causes. These losses have reached critical proportions in some areas. As pollination services decline, human diets could become impoverished in fruits and vegetables that provide us with essential vitamins and micro-nutrients. Wild plant populations that depend on pollinators for reproduction (the majority of flowering plants) may also suffer, with potential cascading effects on other wildlife. This research will utilize a multi-pronged approach to understand how the distribution of habitat patches in a landscape can support wild pollinator communities in agricultural regions and thus ensure the continued delivery of pollination services to crops. This comprehensive approach includes field observations and experiments in the Central Valley of California, development of mathematical models for understanding pollination services across space, and application of these models to pollination studies from around the globe. The increased understanding of pollination services can benefit society by identifying pathways for restoring a diverse community of pollinators to agriculture, and thus helping to reduce the risk of over-reliance on honey bees as a critical input to agricultural production. This research will also contribute to the fundamental understanding of the relationship between changing habitat distributions at the landscape scale and the ecosystem services they produce. Three postdoctoral scientists will be mentored and trained in this project, along with numerous undergraduate students. Results will contribute to public outreach through interactions with the Xerces Society which works with farmers in California and across the U.S. to conserve native pollinator communities to benefit agriculture. Additional outreach will be conducted through the Lincoln Park Zoo in Illinois to increase participation in a citizen science pollination program.

授粉媒介提供了大约35％的全球作物生产和75％的作物类型的果实和种子产量增强。 野生传粉媒介的种群目前正遭受栖息地的损失，而由于疾病，农药和未知原因，北美和欧洲的半含授粉媒介，尤其是使用最广泛的农作物授粉媒介欧洲蜜蜂在北美和欧洲下降。 这些损失在某些地区达到了关键的比例。 随着授粉服务的下降，人类饮食可能会在水果和蔬菜中贫穷，从而为我们提供必需的维生素和微量营养素。 依靠授粉媒介（大多数开花植物）的野生植物种群也可能遭受对其他野生动植物的潜在级联影响。 这项研究将利用一种多管齐下的方法来了解景观中栖息地的分布如何支持农业地区的野生传粉媒介社区，从而确保继续向农作物提供授粉服务。 这种全面的方法包括在加利福尼亚中部山谷中进行的现场观察和实验，开发用于了解跨空间的授粉服务的数学模型，以及这些模型在全球范围内的授粉研究中的应用。 对授粉服务的不断了解可以通过确定恢复多元化授粉媒介社区到农业的途径，从而使社会受益，从而有助于减少过度依赖蜜蜂的风险，以此作为对农业生产的关键投入。 这项研究还将有助于对景观规模不断变化的栖息地分布与他们生产的生态系统服务之间的关系的基本理解。将在该项目中与众多本科生一起在该项目中进行指导和培训三名博士后科学家。结果将通过与Xerces社会的互动来促进公众的宣传，该协会与加利福尼亚州和美国各地的农民合作，以保护本地传粉媒介社区以使农业受益。额外的外展将通过伊利诺伊州的林肯公园动物园进行，以增加参与公民科学授粉计划。
