Scaled chrysophytes are microscopic organisms common to all freshwater environments. Most species grow under very specific conditions, making them excellent indicators of environmental change and of the health of the environments in which they live. These organisms are so named because they form highly ornate structures out of glass, called scales, which are unique in design for each species. These scales accumulate in sediments where they can be recovered later and used to piece together the history of the water body. Study of scaled chrysophytes, including use as bioindicators, has been hampered by the lack of taxonomic resources available to new researchers. The primary objective of this project is to synthesize three decades of research on scaled chrysophytes from thousands of collections made along the east coast of North America, and archive corresponding materials from all samples in international museums. A synthesis of the data is expected to yield insights for new research initiatives on global climate change and for addressing biodiversity and evolutionary questions.Worldwide taxonomic expertise in scaled chrysophytes has significantly declined over the last decade, a fact that has undermined the importance and use of these organisms for advancing our knowledge of key environmental issues such as global climate change. In addition, unlike most groups of organisms, there are no museum collections available to aid new researchers. These facts provided the primary stimuli for this project, namely to develop a comprehensive guide to the organisms and simultaneously archive materials and specimens that directly correspond to the guide in internationally recognized museums.

缩质的菊苣是所有淡水环境常见的微观生物。 大多数物种在非常具体的条件下生长，使其成为环境变化和生活环境健康的绝佳指标。 这些生物之所以如此命名，是因为它们从玻璃（称为鳞片）中形成高度华丽的结构，这些结构在每个物种的设计中都是独特的。 这些鳞片积聚在沉积物中，以后可以恢复，并用来将水体的历史拼凑在一起。 对新研究人员缺乏分类学资源的缺乏，对鳞状ch的研究（包括用作生物指导者）的研究受到了阻碍。 该项目的主要目的是综合北美东海岸成千上万种收藏品的缩放金叶菌的三十年研究，并从国际博物馆中的所有样品中归档相应的材料。预计数据的综合将为全球气候变化以及解决生物多样性和进化问题的新研究倡议提供见解。在过去的十年中，Worldwide的分类学专业知识大大下降，这一事实在这一事实中破坏了我们对这些生物体的重要性和使用，例如我们对关键环境问题的知识，这一事实损害了我们的知识。 此外，与大多数生物体不同，没有博物馆收藏可以帮助新研究人员。 这些事实为该项目提供了主要的刺激，即开发有关生物体的综合指南，并同时对与国际公认的博物馆中的指南直接相对应的归档材料和标本。
