NSF Postdoctoral Fellowships in Biology combine research and training components to prepare young scientists for careers in biology and provide them an opportunity to establish international collaborations and take advantage of research facilities and opportunities abroad. Forging strong international collaborations is mutually beneficial to the U.S. and the foreign hosts. The fellowship to Carly D. Kenkel supports a research and training plan to investigate the evolution of symbiont transmission mode using reef-building corals as a model system. The research will advance basic scientific knowledge concerning the evolution of mutualisms and elevate understanding of the coral-algal symbiosis, the foundation of one of the most ecologically and economically important ecosystems on earth. The host institution is The Australian Institute of Marine Science (AIMS) and the sponsoring scientist is Dr. Line Bay. Training goals include acquiring expertise in novel biochemical techniques, next-generation sequencing methods and bioinformatics analyses. Educational and public outreach activities include establishing a high school internship program at AIMS in collaboration a local school. This fellowship is being funded jointly by the Office of International and Integratiave Activities and the Directorate for Biological Sciences.Symbioses are ubiquitous in the natural world, yet little is known about how transmission mode evolves in any system. Reef-building corals are a good system in which to study this question because symbiont transmission mode has diverged repeatedly and recently across coral lineages. This research tests the hypothesis that vertical symbiont transmission (direct transfer of symbionts from parent to offspring) stabilizes mutualistic relationships. Laboratory experiments use biochemical and physiological assays to quantify resource sharing between coral hosts and algal symbionts in closely related corals with different symbiont transmission strategies. Comparative genomic methods are being used to identify genes involved in the evolution of different transmission modes by looking for signatures of selection.

NSF 生物学博士后奖学金将研究和培训部分结合起来，为年轻科学家从事生物学职业做好准备，并为他们提供建立国际合作和利用国外研究设施和机会的机会。 建立强有力的国际合作对美国和外国东道国来说是互利的。 卡莉·D·肯克尔 (Carly D. Kenkel) 的奖学金支持一项研究和培训计划，以调查使用造礁珊瑚作为模型系统的共生传播模式的演变。 该研究将推进有关互利共生进化的基础科学知识，并提高对珊瑚-藻类共生的理解，珊瑚-藻类共生是地球上生态和经济上最重要的生态系统之一的基础。 主办机构是澳大利亚海洋科学研究所（AIMS），赞助科学家是 Line Bay 博士。 培训目标包括获得新型生化技术、下一代测序方法和生物信息学分析方面的专业知识。教育和公共推广活动包括与当地学校合作在 AIMS 建立高中实习计划。 该奖学金由国际和综合活动办公室和生物科学理事会联合资助。共生在自然界中无处不在，但人们对传播模式在任何系统中如何演变知之甚少。 造礁珊瑚是研究这个问题的一个很好的系统，因为共生传播模式最近在珊瑚谱系中反复出现分歧。这项研究检验了垂直共生体传播（共生体从亲本到后代的直接转移）稳定互利关系的假设。 实验室实验使用生化和生理测定来量化具有不同共生体传播策略的密切相关的珊瑚中珊瑚宿主和藻类共生体之间的资源共享。比较基因组方法通过寻找选择特征来识别参与不同传播模式进化的基因。
