DEB-9972120Siver The primary focus of this project will be to survey and inventorythe scaled chrysophyte and diatom floras in seepage lakes and ponds alonga transect from Maine to Florida, with a focus on coastal Maine, Cape Cod,the Carolina Bay region and central Florida. Although seepage lakes fromeach region along this transect differ in their origin, they are similarin being acidic, poorly buffered, and high in sodium and chlorideconcentrations. We plan to critically examine collections in order tofully depict each flora, describe new species, gain knowledge on raretaxa, and identify habitats that are particularly rich and diverse withthese organisms. We will use our data to address the following question.How many waterbodies within each region, or between all regions, will needto be set aside and protected in order to conserve the biodiversitycontained within these two organismal groups? A basic understanding ofthis question is needed before conservation and biodiversity managementplans can be designed and implemented for these and other microscopictaxa. We will also continue to develop our World Wide Web-based resourcesto inventory, archive and disseminate research results using searchabledatabases, expand our library of images of important taxa, and to continueto expand our ecological knowledge of these siliceous algal groups.Lastly, we will train a group of undergraduates in the techniques andapproaches used in the taxonomy and identification of scaled chrysophytesand diatoms.

DEB-9972120Siver 该项目的主要重点是对缅因州至佛罗里达州横断面沿线的渗漏湖和池塘中的金藻和硅藻植物群进行调查和清查，重点是缅因州沿海、科德角、卡罗莱纳湾地区和佛罗里达州中部。 尽管该样带沿线各个地区的渗漏湖来源不同，但它们的相似之处在于都是酸性、缓冲不良、钠和氯浓度高。 我们计划严格检查馆藏，以便全面描述每种植物群、描述新物种、获得有关稀有类群的知识，并确定这些生物体特别丰富和多样化的栖息地。我们将使用我们的数据来解决以下问题。每个区域内或所有区域之间需要预留和保护多少个水体，以保护这两个生物群体中包含的生物多样性？ 在为这些和其他微观类群设计和实施保护和生物多样性管理计划之前，需要对这个问题有基本的了解。 我们还将继续开发基于万维网的资源，以使用可搜索的数据库来盘点、存档和传播研究结果，扩展我们重要分类单元的图像库，并继续扩展我们对这些硅质藻类的生态知识。最后，我们将培训一组本科生用于鳞片金藻和硅藻的分类和识别的技术和方法。
