NSF Postdoctoral Fellowships in Biology combine research and training components to prepare young scientists for careers in emerging areas where biology intersects with other scientific disciplines, in this case with mathematics. The Fellows are expected to lead the nation's scientific workforce of the future. This fellowship to Holly Moeller supports research and training on metabolic flexibility and marine ecosystem function. The host institution is the Woods Hole Oceanographic Institution, and the sponsoring scientists are Drs. Matthew D. Johnson and Michael G. Neubert. Training goals include coupling microbiological and modeling techniques. Educational and public outreach includes mentoring undergraduate and high school students at Woods Hole Oceanographic Institution by including them in experimental subprojects and by continuing as a scientific writer to place environmental issues in the public eye.The research investigates the environmental selection pressures that produce mixotrophs - organisms that can fuel their metabolism through either autotrophy, i.e., photosynthesis, or heterotrophy, ingestion of organic matter. Mixotrophy is widespread in aquatic microbial communities, yet remains poorly represented in ecosystem models. The research examines, from an evolutionary perspective, how an organism maintains metabolic flexibility, rather than specializing in just one mode of nutrition, and the importance of these types of organisms to primary production, nutrient cycling, and other ecosystem functions, particularly in the ocean where climate change is likely to increase their numbers. To test the physiological limits and competitive ability of mixotrophic marine microbes, laboratory studies are being extended to modeling broader questions of eco-evolutionary dynamics.

NSF生物学的博士后研究金结合了研究和培训组成部分，以准备年轻科学家在新兴地区的职业，在这种情况下，在这种情况下，在这种情况下，在这种情况下，在这种情况下，在这种情况下，在这种情况下与数学相交。 预计研究员将带领美国的科学劳动力。 授予Holly Moeller的奖学金支持有关代谢灵活性和海洋生态系统功能的研究和培训。 房东机构是伍兹洞海洋学机构，赞助科学家是Drs。 Matthew D. Johnson和Michael G. Neubert。 培训目标包括耦合微生物和建模技术。教育和公众外展包括在伍兹孔海洋学机构中指导本科生和高中生，通过将它们包括在实验性次要项目中，并继续作为科学作家将环境问题置于公众眼中。该研究调查了产生混音的环境选择压力 - 可以通过自动植物来促进其代谢，i.ee.eboterrophers，或者构成象征，或者构成了象征。 在水生微生物群落中，混合营养广泛，但在生态系统模型中的代表仍然很差。 该研究从进化的角度研究了生物体如何保持代谢柔韧性，而不是只专门研究一种营养方式，以及这些类型的生物对初级生产，营养循环和其他生态系统功能的重要性，尤其是在海洋中，气候变化可能会增加其数量。 为了测试混合营养海洋微生物的生理极限和竞争能力，实验室研究正在扩展到对生态进化动力学的更广泛问题进行建模。
