This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2011, Intersections of Biology and Mathematical and Physical Sciences. The fellowship supports a research and training plan in a host laboratory for the Fellow at the intersection of biology with mathematics and statistics. The title of the research and training plan for this fellowship to Julie Jedicka is "Prey selection by high order predators: modeling Western Bluebird foraging in patchy environments." The host institution for this research is University of California, Berkeley with sponsoring scientists Drs. Rodrigo Almeida, Perry de Valpine and Wayne Getz. Insectivorous birds are ubiquitous, multi-trophic-level predators, whose ecological function is poorly understood, primarily because their consumption patterns elude researchers due to their high mobility and predation of relatively small organisms. This research develops novel experimental techniques that quantify the prey of a model predator, the Western Bluebird (Sialia mexicana). Diet is analyzed through fecal DNA of nestling and adult bluebirds foraging in patchy environments. By pairing these data with arthropod availability in the field and prey consumed, customized mathematical models are being developed drawing from hierarchical statistical models, dynamic state variable models, and a biomass transformation approach to model populations in food webs. The scientific payoff includes interdisciplinary techniques for quantifying foraging niches not previously attainable and for understanding the ecological consequences of high order predator extinctions or exotic invasions.Training goals include gaining expertise in mathematical modeling and statistics. Broader impacts of this research include outreach to diverse student groups through workshops and existing programs to broaden participation. Mathematical models and sequence data are being made available on the web and through existing open databases.

这一行动为2011财年的NSF生物学博士后研究奖学金提供资金，生物学与数学和物理科学的交叉点。该研究金支持在一个东道实验室为研究员开展生物学与数学和统计学交叉研究和培训计划。朱莉·杰迪卡研究和培训计划的标题是“高阶捕食者的猎物选择：在不规则环境中模拟西部蓝鸟觅食”。“这项研究的主办机构是加州大学伯克利分校，赞助科学家罗德里戈·阿尔梅达博士、佩里·德·瓦尔平博士和韦恩·盖兹博士。食虫鸟类是普遍存在的，多营养级的捕食者，其生态功能知之甚少，主要是因为它们的消费模式躲避研究人员，由于其高流动性和捕食相对较小的生物体。这项研究开发了新的实验技术，量化的模型捕食者，西部蓝鸟（Sialia mexicana）的猎物。通过在斑块环境中觅食的雏鸟和成年蓝知更鸟的粪便DNA分析饮食。通过将这些数据与节肢动物在该领域的可用性和猎物消耗配对，正在开发定制的数学模型，从分层统计模型，动态状态变量模型和生物量转换方法来模拟食物网中的种群。 科学回报包括量化觅食生态位以前无法实现的跨学科技术，以及理解高阶捕食者的生态后果或外来入侵。培训目标包括获得数学建模和统计方面的专业知识。这项研究的更广泛的影响包括通过研讨会和现有的计划扩大参与，以扩大不同的学生群体。 数学模型和序列数据可在网上和通过现有的开放数据库获得。
