Support of the Diatom Herbarium of The Academy of Natural Sciences of Philadelphia

自然科学院硅藻标本馆， 费城包含超过110，000个编目标本幻灯片， 224，000件未编目的拍品，4，500件模式标本的卡片档案， 60，000个地点，160，000个分类出现，51，000个书目 引用和200，000个未处理的样本，使其成为最大的 在西半球的同类收藏。 爱德华博士 负责植物标本馆的馆长Theriot继续计划 改进标本的物理保存，特别是 模式标本，用于理论和应用研究。 硅藻是浮游植物的一个不同的群体， 用作环境指标，是许多 生物地层学和进化研究。 系统收集 化石和现代硅藻对这项研究至关重要， 费城的硅藻标本馆是世界上 其类型的重要集合。 未来的全球研究 气候变化、进化过程和环境质量 将依赖于系统的持续增长和改进 像这样的收藏。

The Diatom Herbarium of the Academy of Natural Sciences, Philadelphia contains more than 110,000 catalogued specimen slides, 224,000 uncatalogued lots, card files for 4,500 type specimens, 60,000 localities, 160,000 taxon occurrences, 51,000 bibliographic citations, and 200,000 unprocessed samples, making it the largest collection of its type in the western hemisphere. Dr. Edward Theriot, Curator in charge of the Herbarium, plans continued improvement in the physical preservation of specimens, especially type specimens, for use in pure and applied research. Diatoms are a diverse group of phytoplankton that are widely used as environmental indicators, and are the subjects on many biostratigraphic and evolutionary studies. Systematic collections of fossil and modern diatoms are essential to this research, and the Diatom Herbarium in Philadelphia is one of the world's most important collections of its type. Future research on global climate change, evolutionary processes, and environmental quality will rely on the continued growth and improvement of systematic collections such as this.
