The overall goal of this project is to discover novel viruses in Yellowstone hot springs, and learn what role they play in determining composition and function of the microbial communities in which they exist. The specific objective of the research is to significantly contribute to our understanding of virus diversity, ecology, and evolution. The specific aims are to (i) significantly expand knowledge of virus diversity and (ii) elucidate the mechanism(s) and impacts of virus movement on virus and microbial community structure and dynamics. These aims will be accomplished by temporal sampling and analysis of total virus communities associated with high temperature (80°C) acidic (pH4.0) hot springs found in Yellowstone National Park. The effects of virus movement and the mechanism of movement will be investigated experimentally by blocking migration within a hot spring and by directly sampling the air column for viruses, respectively.The broader significance and scientific importance of this project is to understand how and to what extent viruses influence Earth's ecosystems. This research is aimed at beginning to overcome our ignorance of virus diversity and function in nature due to the limited attention that they have received as compared to their cellular hosts. The broader impacts of this research include, but extend well beyond the training of postdocs and graduate, undergraduate and high school students. These broader impacts encompass development of a dynamic outreach program promoting Yellowstone's thermal environments, including but not limited to, (i) an outreach program that targets K-12 learners and teachers nationally through the development of science curriculum; (ii) a field-based teacher training class; (iii) participation in a variety of community outreach programs including a community lecture series; (iv) participation in field experiences for adults; (v) participation in ParKids, a 3-day thermal biology based learning experience for kids in Yellowstone Gateway communities; and (vi) distribution of national and international film documentaries, radio and popular press articles concerning Yellowstone's thermal biology and our research.

该项目的总体目标是在黄石温泉中发现新型病毒，并了解它们在决定其存在的微生物群落的组成和功能方面发挥的作用。这项研究的具体目标是为我们对病毒多样性、生态学和进化的理解做出重大贡献。具体目标是（i）显着扩大病毒多样性的知识和（ii）阐明病毒运动对病毒和微生物群落结构和动态的机制和影响。这些目标将通过对黄石国家公园中发现的高温（80°C）酸性（pH 4.0）温泉相关的总病毒群落进行时间采样和分析来实现。通过在温泉中阻断病毒的迁移和直接在空气柱中采集病毒样本，对病毒的迁移效果和迁移机制进行实验研究。本项目的更广泛意义和科学价值在于，了解病毒如何以及在多大程度上影响地球生态系统。这项研究的目的是开始克服我们对病毒多样性和功能的无知，因为与它们的细胞宿主相比，它们受到的关注有限。这项研究的更广泛的影响包括，但远远超出了博士后和研究生，本科生和高中生的培训。这些更广泛的影响包括制定一个动态的外展计划，促进黄石的热环境，包括但不限于：（i）通过开发科学课程，针对全国K-12学习者和教师的外展计划;（ii）实地教师培训班;（iii）参与各种社区外展计划，包括社区讲座系列;（iv）参与成人的实地体验;（v）参与ParKids，为黄石门户社区的孩子们提供为期3天的基于热生物学的学习体验;以及（vi）分发关于黄石热生物学和我们的研究的国家和国际电影纪录片、广播和大众媒体文章。
