Pelagic biogeography, the study of the distribution of organisms in the open ocean, has been limited by the inability to determine the genetic composition and structure of marine species. Dr. George Matsumoto and colleagues will try to apply new molecular systematic methods of DNA analysis to samples of two poorly known groups of pelagic organisms, siphonophores and ctenophores. Emphasis in the laboratory will be placed on analyzing mitochondrial DNA and ribosomal DNA, because of the demonstrated utility of these classes of DNA in other animal groups. If successful, the study will yield data that will help characterize the genetic diversity and differences within and among groups of these colonial invertebrates. The organisms under study have gelatinous outer sheaths, which present special problems for the extraction and analysis of DNA. Thus, the SGER mechanism is especially appropriate for support of this exploratory research.

远洋生物地理学是对公海生物分布的研究，由于无法确定海洋物种的遗传组成和结构而受到限制。 George Matsumoto 博士及其同事将尝试将新的 DNA 分析分子系统方法应用于两个鲜为人知的远洋生物群体（管水母和栉水母）的样本。 实验室的重点将放在分析线粒体 DNA 和核糖体 DNA，因为这些类别的 DNA 在其他动物群体中已被证明具有实用性。 如果成功，该研究将产生的数据将有助于描述这些群体无脊椎动物群体内部和群体之间的遗传多样性和差异。 所研究的生物体具有凝胶状外鞘，这给 DNA 的提取和分析带来了特殊的问题。 因此，SGER机制特别适合支持这项探索性研究。
