Dr. Arthur G. Humes of Boston University proposes continuation of his study of the taxonomy and distribution of copepods (a common representative of the Crustacea) found in deep-sea hydrothermal vent systems in several oceans. Dr. Humes has been actively describing representatives of these unusual ecosystems since their discovery through the use of submersibles ten years ago, and he has discovered dozens of new species under the auspices of an earlier award. The existence of heretofore unknown species on these isolated patches of biological richness in the deep sea raises important questions about evolution and biogeography. Are they the survivors of previously widespread species that dwindled and became isolated, or are they specialized and long-lived inhabitants that diverged long ago, or are they recently evolved and short-lived residents on these ephemeral food-sources? Can they disperse among the distant vents, or do they arrive there infrequently and accidentally? The proposed taxonomic work will form the foundation for future research projects that explore these controversial subjects, and will have impact on a wide audience of biologists.

亚瑟博士G.波士顿大学的Humes提议继续研究在几个海洋的深海热液喷口系统中发现的桡足类（甲壳纲的一种常见代表）的分类和分布。自从十年前通过使用潜水器发现这些不寻常的生态系统以来，休姆斯博士一直在积极描述这些生态系统的代表，他在早期奖项的赞助下发现了数十个新物种。在深海中这些生物丰富的孤立区域中存在着迄今为止未知的物种，这提出了关于进化和海洋地理学的重要问题。它们是以前广泛分布的物种的幸存者，减少并变得孤立，还是很久以前就分化的专门和长寿的居民，或者它们是最近进化的，这些短暂的食物来源的短命居民？它们能在遥远的火山口中扩散吗？还是偶尔偶然地到达那里？拟议的分类工作将为未来探索这些有争议的主题的研究项目奠定基础，并将对生物学家的广泛受众产生影响。
