This research project will continue studies of a taxonomically definitive group of early evolving (single-chambered) Foraminifera at both multi-gene molecular and ultrastructural levels of analysis, in order to generate more robust and detailed phylogenies of these ecologically-important organisms. Studies will be extended to include members of the enigmatic genus Gromia, to better define their ecological significance and placement within the protistan supergroup Rhizara. Together, these structural and molecular data will be used to complete taxonomic descriptions of over 20 new rhizarian species. The research will develop rapid molecular screening methods for future ecological studies of rhizarian protists, and uncover the driving forces that led to their diversification. A range of educational activities will target local and national audiences, and include development of hands-on, standards-based, innovative science classroom activities. In addition, a short art/science documentary film depicting research on the biology and evolution of Antarctic rhizarian protists will form the basis of a workshop hosted by the Capital Region Center for Arts in Education.

该研究项目将继续在多基因分子和超微结构分析水平上对早期进化（单室）有孔虫的分类学确定性组进行研究，以产生这些生态重要生物的更强大和详细的遗传学。研究将扩大到包括神秘的属Gromia的成员，以更好地确定其生态意义和原生生物超群Rhizara内的位置。总之，这些结构和分子数据将用于完成20多个新的根茎类物种的分类描述。这项研究将为未来的根茎原生生物生态学研究开发快速分子筛选方法，并揭示导致其多样化的驱动力。一系列教育活动将针对当地和全国观众，包括开发实践性、基于标准的创新科学课堂活动。此外，一个简短的艺术/科学纪录片描述了南极根茎原生生物的生物学和进化的研究将构成由首都地区艺术教育中心主办的研讨会的基础。
